1. Introduction
This It’s well known that many in the world areas
enduring scare resources of potable, irrigation and
industrial water. And one of the scientific solutions
for this problem is distillation of sea water by the
thermal method [1]. Recent years were characterized
by increase percent of thermoelectric centers for
producing distillation water and electric power
required to cover the electric network in most world
countries and especially oil developed countries [ 1 ,
2 , 3 ]. Beside this, the stations of producing steam
electric power in most world countries are still
covering high percent from the load of electric power
consummation in the network. A great division of
these stations became from the technical aspect not
economic according to the new international
standards of durability and rate of consuming fuel to
produce electric power [4].
Modern study findings denote the economic
effectiveness to use steam distillation units of
multiple effect in the thermoelectric steam centers
allocated for production of electric power and
distillation water [5]. But in case of countries in
which network of electric power depends mainly on
condensation steam stations, it’s necessary to think
about preparing thermal power for distillation units
aforementioned via using steam from condensation
turbines or development of these turbines to work
with the system of steam turbines of versus pressure.
And this is when the distillation inside the electric
station or near to it. It’s notice worthy that this case
must take into consideration the design ability and
allowable increase in the power loaded on the phases
of steam turbines [6]. And due to continuous
scientific researches to submit what is more
economically effective in the field of electric power

production the researcher headed to adopt the idea of
dual cycle in development and expansion of old
steam stations [7, 8]. Upon the aforementioned, we
shall tackle in this study the investigation of
effectiveness of development of basic design for
condensation steam station to the dual press
thermoelectric center in which the electric power and
thermal power are produced as required for units of
evaporation distilling units of multiple effects.
2. Basic Design for the studied station
The basic design for the steam station (figure 1) in
steam boiler (SB) with production capacity of (320
ton/hr) and unit of condensation steam turbine of one
axis and design capacity of 84.65 MW and the steam
turbine consists of two cylinders (HPT, LPT) to
supply steam prepared by the boiler (TSB= 510 C ;
PSB= 92.2 bar) and includes four points to exhaust
steam from high pressure cylinder and low pressure
cylinder for the objective of recovery heating for
supply water (table 1).
Table 1. Properties of steamat various points of the turbine extraction
3. Specifications of Studied Design
The suggested design for development of basic
design of studied steam station provided in figure (2)
where the design of the steam station is amended to
the dual thermoelectric center in which the thermal
power for the exhaust gases out of the gas turbine
from the dual press steam boiler (HRSB) assigned to
produce the amount of steam required for steam
turbine in the basic design of the station in case of
new operating system. Thereupon, the steam
produced in the high pressure phase from the boiler
after achieving a volume of work inside the cylinder
of high pressure for steam turbine, shall be mixed
with the steam volume produced in low pressure
phase in the boiler. Where the quantity of steam
produced in both phases of pressure in the boiler
inside the low pressure cylinder till the preparation
pressure for steam in the distillation unit.In the
suggested design, the condenser and thermal
exchangers allocated for recovery heating of supply
water and main condenser were canceled. The design
of condensation steam turbine is developed to work
with system of thermal steam turbines of versus
pressure.
Where the last three phases have been canceled for
supplying the steam from low pressure cylinder so as
to achieve the required steam specifications for
distillation unit at the end of procedures of supplying
steam inside the turbine and preserving the point of
exhausting steam allocated for tank of extracting air
in the basic design (which works according to the
studied design at pressure of PD = 2.5 bar).
For the objective of decreasing the amount of steam
exhausted for the tank of extracting air, the main
condenser is heated (to the temperature less than the
degree saturation corresponding to the pressure of air
extraction tank with amount of 5°C) via putting a
thermal exchanger allocated for this objective in the
boiler. In addition to the aforementioned, it’s
considered the existence of supply tank (FV).
In which an amount of flash steam is produced via
the exhausted amount of water from cylinders of both
boiler phases, and so thermal exchanger (RFWH) to
heat up the compensation water for the thermoelectric
center via maximum use of thermal power remaining
in the exhausted water fromthe supply tank.
As to the design of distillation unit (MED) it consists
of a number of consequent steam condensers forming
multiple effects for the distillation unit.

And the saline solution is prepared for these effects
on parallel basis among them exhausting the
concentrated saline solution from one effect to the
other consecutively (according to hierarchy of
pressure inside the effects) and so the design of
distillation unit includes a separate condenser for the
quantity of steam produced in the last effect from
distillation unit. Where as part of cooling water is
used for this condenser in preparing the amount of

CC, gas turbine GT, electric generator G).
Second design (gas turbine unit designed with simple
circuit with consecutive combustion for fuel, and
hence the gas turbine unit design shall include, in
addition to basic parts aforementioned in the first
design, a circular combustion room after the first
phase of gas turbine).
4. Method ofstudying the effectiveness of
studied design
To study the thermal and environmental effectiveness
of thermoelectric centers of dual press, it’s required
to calculate the thermal design for a number of
different alternatives for the studied design
characterized from each other with change in the gas
turbine design used and design characterizations
studied forming a consecutive coordination for the
objective of calculating the thermal and
environmental economic indicators for these
alternatives in each case.It’s notice worthy that the
basic design characteristics studied in this case: the
primary temperature degree for gases before gas
turbine (T3), air pressure percent in the compressor
(PRC), steam pressure prepared for the distillation
unit (PT) according to this, the design number for
effects of distillation unit (N).Yet, the thermal and
environmental effectiveness shall be defined in this
case via the amount of saving in the quantity of fuel
consumed from the electric network due to the joint
production process for electric power and a
distillation unit from type of Reverse osmosis for
production of distillation water. Hence, the amount of
saving in the fuel amount consumed in the electric
network due to development of the basic design for
the condensation steam station to a dual
thermoelectric center allocated for production of
electric power and distillation water:
Whereas:
BGT, NGT. The electric power produced (MW) and
fuel consumption rate (ton/hr) for the gas turbine unit
respectfully.
NST. Electric power produced (MW) for the gas
turbine unit in case of new operation system.
(NEST), (BSB). Electric power produced (MW) and
rate of fuel consumption (ton/hr) for the boiler in case
of basic design of the station respectfully.
NFP2 , NFP1. Electric power consumed (MW) in the
supply pump for the first and second phase fromthe
boiler respectfully.
EST. Efficiency of dual recovery station for
producing electric power in the network.
Qcv. Thermal value for qualitative fuel (Kj/Kg).
NMED, NRO. Rate of consumption of qualitative
electric power (MW.hr/ton) for producing distillation
water in the distillation unit from type of Reverse
osmosis and evaporation unit of multiple effects
respectfully.DDW. Quantity of distillation water
produced (ton/hr).Hence, the proper alternative is to
give the maximum value for equation (1) (any
alternative which has the studied design for
distillation unit and gas turbine unit and so
thermodynamic characteristics studied for this unit
gives the maximum effectiveness possible via the
amount of saving in the fuel quantity consumed to
produce electric power and distillation water).
It’s notice worth in the process of building the sport
model for calculating the thermal design for the dual
thermoelectric center, the thermoelectric centers
calculation method is used [9], and method of
calculating the gas turbine units of high primary
thermal degrees for gases [10], and method of
calculating steam boilers allocated for using
secondary resources for power [11], and method of
calculating the evaporating distillation units of
multiple effects [12]. In addition to the
aforementioned, the method of calculating the gas
turbine units aforementioned has been amended to
deal with gas turbine units of consecutive combustion
and defining the percent of gas expansion in the first
phase of gas turbine from requirements of the number
of phases in this turbine and equal distribution for
amount of decrease in the gas power among these
phases [13].
5. The results of study of the effectiveness of
the design studied
The effect of design of gas turbine unit and basic
design specifications aforementioned (paragraph 4)
on the measuring the economic effectiveness of the
studied design for dual thermoelectric center (amount
of saving in the quantity of fuel consumed in electric
networks and distillation water) - has been studied.

quantity of fuel in relation (1) at different primary
temperature degrees for gases (T3) before gas
turbine. The amount of steam required for the steam
turbine unit by an amount which is larger than the
increase in the qualitative job of gas turbine unit.The
effect of the properties of gas turbine unit on the
quantity of steam produced in the two phases of the
pressure of the boiler was also studied; where it was
noted of figure (5) that, at a fixed ratio of air
compression and an increase of initial temperature of
gases, the amount of steam produced in the high-
pressure stage of the boiler DSB1 is rising because of
the increased amount of thermal power available to
produce steam at this stage due to the high
temperature gases after the gas turbine . It was also
observed that the amount of steam produced in the
phase of the low-pressure of boiler DSB2 is declined
together with an increase of the initial temperature of
gases before the gas turbine. The reason for this
could be attributed to the low temperature of the
combustion gases after the provider of high-pressure
phase of the boiler as a result of increasing the
amount of thermal power required to heat the feed
water for such phase of the boiler. At the increase of
the compression ratio of air temperature and fixing of
the initial temperature of gases, it was observed of
Figure (5) that the quantity of steam produced in the
high-pressure stage of the boiler is declined, because
of the low amount of thermal power available to
produce steam at this stage. The quantity of steam
produced in the low pressure phase of the boiler
increases with higher ratio of air compression. The
reason for this is due to the low amount of water
needed to feed the high-pressure-phase of the boiler,
and then the high temperature combustion gases after
the provider of this stage of the boiler and thus an
increase of the amount of thermal power available to
produce steam in the low pressure phase of the
boiler.The effect of vapor pressure prepared for PT
desalination unit and efficiency of the compensatory
EST plant for the production of electric power, as
well as the rate of electrical power consumption for
the production of desalinated water in the
desalination unit of reverse osmosis type on the
amount of savings of the quantity of fuel consumed
DBST as shown in Figure 6, where it is noted the
drop in the amount of savings of the quantity of fuel
consumed (DBST1) together with an increase of
steam pressure prepared for desalination unit in the
case of recovery of the hydraulic power of water
drained from the reverse osmosis unit (NRO = 6
kW.hr / ton). The reason for this is due to a drop in
electrical power produced of the steam turbine unit
(NST, (Figure 7) ) in a greater amount than the
increase of the rate of consumption of electrical
power of the compensatory desalination unit as a
result of the high amount of desalinated water
produced for the electro-thermal center (DDW,
(Figure 7). In the case of non-recovery of hydraulic
power for water drained from the desalination unit
(NRO = 15 kW.hr / ton), it is observed of Figure 7
the high amount of savings of the quantity of fuel
consumed (DBST2) together with an increase of
steam pressure prepared for the desalination unit,
because of the high rate of electrical power
consumption for the production of desalinated water
in the reverse osmosis unit, and then an increase of
the rate of fuel consumption on the production of
desalinated water in the separated production process
in an amount that is greater than the rate of fuel
consumption in the double electro-thermal center for
the production of thermal power for the desalination
unit. On fixing the vapor pressure prepared for the
desalination unit and an increase of the efficiency of
the compensatory desalination plant, it is noted of
Figure (6) that the amount of savings of the quantity
of fuel consumed is declined because of the low rate
of fuel consumption for the production of electric
power in the compensatory station.
The effect of vapor pressure prepared for desalination
unit PT on the designed number of effects of
desalination unit N as shown in Figure 7; where it is
noted that an increase of steam pressure prepared for
desalination unit leads to a rise in the designed
number of effects of the desalination unit; and then
the low rate of qualitative thermal power
consumption of desalination unit (QR) as a result of
the high amount of thermal power recovery of
desalination unit, and therefore a high amount of
desalinated water produced (DDW).

Figure (7) also shows a slight increase in the amount
of thermal power prepared for the desalination unit
QT with a high steam pressure prepared for the
desalination unit. This is because of the high
temperature of condensed steam coming from the
desalination unit and the fixed amount of steam
prepared for this unit. The environmental
effectiveness of designing the double electro-thermal
center has been studied together with the impact of
gas turbine unit on such effectiveness; where it is
noted of Figure (8) the amount of decrease in the
quantity of nitrogen oxides (DMNOx) and carbon
dioxide (DMCO2) exposed to the surrounding
environment as a result of the use of the design
proposed for the double electro-thermal center
compared with the separate process of production of
electric power and water desalination. The reason for
this can be attributed to the decline in the rate of fuel
consumption for production of the two types of
power (electrical and thermal) in the thoughtful
design of the double electro-thermal center and low
the amount of combustion gases exposed to the
surrounding environment. It is also noted of Figure
(8) the increase of the amount of the decrease in the
quantity of nitrogen oxides and carbon dioxide
exposed to the surrounding environment with a high
ratio of air compression in the gas turbine unit,
because of the increase in the amount of electricity
produced and the high efficiency of the double
electro-thermal center for production of this power,
and then an increase in the fuel consumption rate for
production of electric power in the compensatory unit
which leads to an increase in the amount of
combustion gases exposed to the surrounding
environment in the separate production process of
electric power and desalinated water.Figure (8) also
shows environmental effectiveness of the use of gas
turbine units of sequential combustion. Figure (7)
also shows a slight increase in the amount of thermal
power prepared for the desalination unit QT with a
high steam pressure prepared for the desalination
unit. This is because of the high temperature of
condensed steam coming from the desalination unit
and the fixed amount of steam prepared for this
unit. The environmental effectiveness of designing
the double electro-thermal center has been studied
together with the impact of gas turbine unit on such
effectiveness; where it is noted of Figure (8) the

The reason for this can be attributed to the decline in
the rate of fuel consumption for production of the
two types of power (electrical and thermal) in the
thoughtful design of the double electro-thermal

exposed to the surrounding environment. It is also
noted of Figure (8) the increase of the amount of the
decrease in the quantity of nitrogen oxides and
carbon dioxide exposed to the surrounding
environment with a high ratio of air compression in
the gas turbine unit, because of the increase in the
amount of electricity produced and the high
efficiency of the double electro-thermal center for
production of this power, and then an increase in the
fuel consumption rate for production of electric
power in the compensatory unit which leads to an
increase in the amount of combustion gases exposed
to the surrounding environment in the separate
production process of electric power and desalinated
water.

thermal plants and centers, where the lowest level of
increase in the amount of decrease in the quantity of
nitrogen oxides and carbon dioxide exposed to the
surrounding environment reached to 14.9% compared
with the use of 1st thoughtful design of gas turbine
unit. The reason for this is due to the high efficiency
of the double plant or the double electro-thermal
center, and then a drop of the rate of fuel
consumption at the double plant or the double
electro-thermal center for production of electrical
power.
6. Summary findings and recommendations
The study results indicate the effectiveness of the
proposed design to :
1. The minimum amount of savings of fuel
consumed is 77.9 kg / hr for each MW of
electrical power produced by the steam plant.
Accordingly, the amount of the decrease in the
quantity of nitrogen oxides is 0.26 kg / MW.hr
and carbon dioxide is 241.8 kg / MW.hr exposed
to the surrounding environment. That is when the
vapor pressure prepared for desalination unit is
0.3 bar and accordingly the designed number of
effects of desalination unit is 8 and the amount
of desalinated water produced is 15.7 ton /
MW.hr.
2. The amount of electricity produced for the
electro-thermal center depends mainly on the
design of electric power for the steam turbine
unit as well as on the design of this unit.
3. The thermal and environmental efficiency of the
electro-thermal center increases with the increase
of basic thermodynamic properties of gas turbine
unit. The use of gas turbine units of initial high
temperature of gases leads to an increase in the
efficiency of electro-thermal center for
production of electrical power, and then an
increase in the amount of savings of the quantity
of fuel consumed despite the decline in the
amount of the increase in the quantity of

consumed and environmental indicators
(paragraph 1.6) mentioned above reached to 14.9
%.
5. The increase of steam pressure prepared for
desalination unit from 0.3 bar to 0.38 bar leads to
an increase in the quantity of desalinated water
produced by 15.3 % (as a result of low rate of
thermal power qualitative consumption of
desalination unit) as well as the decline in
electrical power produced for steam turbine unit
at a rate of 2.9%.
6. The need of an economic thermal study to
determine design specifications and ideal
thermodynamic properties for the proposed
design which gives the maximum possible
economic efficiency, taking into account the
amount of change in the cost of the gas turbine
unit and the boiler dedicated to the exploitation

this unit; this is for the effect of these properties
and specifications on the quantity of steam

Introduction This It’s well known that many in the world areas enduring scare resources of potable, irrigation and industrial water. And one of the scientific solutions for this problem is distillation of sea water by the thermal method [1]. Recent years were characterized by increase percent of thermoelectric centers for producing distillation water and electric power required to cover the electric network in most world countries and especially oil developed countries [ 1 , 2 , 3 ]. Beside this, the stations of producing steam electric power in most world countries are still covering high percent from the load of electric power consummation in the network. A great division of these stations became from the technical aspect not economic according to the new international standards of durability and rate of consuming fuel to produce electric power [4]. Modern study findings denote the economic effectiveness to use steam distillation units of multiple effect in the thermoelectric steam centers allocated for production of electric power and distillation water [5]. But in case of countries in which network of electric power depends mainly on condensation steam stations, it’s necessary to think about preparing thermal power for distillation units aforementioned via using steam from condensation turbines or development of these turbines to work with the system of steam turbines of versus pressure. And this is when the distillation inside the electric station or near to it. It’s notice worthy that this case must take into consideration the design ability and allowable increase in the power loaded on the phases of steam turbines [6]. And due to continuous scientific researches to submit what is more economically effective in the field of electric power RESEARCH ARTICLE OPEN ACCESS

Upon the aforementioned, we shall tackle in this study the investigation of effectiveness of development of basic design for condensation steam station to the dual press thermoelectric center in which the electric power and thermal power are produced as required for units of evaporation distilling units of multiple effects. 2. Basic Design for the studied station The basic design for the steam station (figure 1) in steam boiler (SB) with production capacity of (320 ton/hr) and unit of condensation steam turbine of one axis and design capacity of 84.65 MW and the steam turbine consists of two cylinders (HPT, LPT) to supply steam prepared by the boiler (TSB= 510 C ; PSB= 92.2 bar) and includes four points to exhaust steam from high pressure cylinder and low pressure cylinder for the objective of recovery heating for supply water (table 1). Table 1. Properties of steamat various points of the turbine extraction 3. Specifications of Studied Design The suggested design for development of basic design of studied steam station provided in figure (2) where the design of the steam station is amended to the dual thermoelectric center in which the thermal power for the exhaust gases out of the gas turbine from the dual press steam boiler (HRSB) assigned to produce the amount of steam required for steam turbine in the basic design of the station in case of new operating system. Thereupon, the steam produced in the high pressure phase from the boiler after achieving a volume of work inside the cylinder of high pressure for steam turbine, shall be mixed with the steam volume produced in low pressure phase in the boiler. Where the quantity of steam produced in both phases of pressure in the boiler inside the low pressure cylinder till the preparation pressure for steam in the distillation unit.In the suggested design, the condenser and thermal exchangers allocated for recovery heating of supply water and main condenser were canceled. The design of condensation steam turbine is developed to work with system of thermal steam turbines of versus pressure. Where the last three phases have been canceled for supplying the steam from low pressure cylinder so as to achieve the required steam specifications for distillation unit at the end of procedures of supplying steam inside the turbine and preserving the point of exhausting steam allocated for tank of extracting air in the basic design (which works according to the studied design at pressure of PD = 2.5 bar). For the objective of decreasing the amount of steam exhausted for the tank of extracting air, the main condenser is heated (to the temperature less than the degree saturation corresponding to the pressure of air extraction tank with amount of 5°C) via putting a thermal exchanger allocated for this objective in the boiler. In addition to the aforementioned, it’s considered the existence of supply tank (FV). In which an amount of flash steam is produced via the exhausted amount of water from cylinders of both boiler phases, and so thermal exchanger (RFWH) to heat up the compensation water for the thermoelectric center via maximum use of thermal power remaining in the exhausted water fromthe supply tank. As to the design of distillation unit (MED) it consists of a number of consequent steam condensers forming multiple effects for the distillation unit.

Second design (gas turbine unit designed with simple circuit with consecutive combustion for fuel, and hence the gas turbine unit design shall include, in addition to basic parts aforementioned in the first design, a circular combustion room after the first phase of gas turbine). 4. Method ofstudying the effectiveness of studied design To study the thermal and environmental effectiveness of thermoelectric centers of dual press, it’s required to calculate the thermal design for a number of different alternatives for the studied design characterized from each other with change in the gas turbine design used and design characterizations studied forming a consecutive coordination for the objective of calculating the thermal and environmental economic indicators for these alternatives in each case.It’s notice worthy that the basic design characteristics studied in this case: the primary temperature degree for gases before gas turbine (T3), air pressure percent in the compressor (PRC), steam pressure prepared for the distillation unit (PT) according to this, the design number for effects of distillation unit (N).Yet, the thermal and environmental effectiveness shall be defined in this case via the amount of saving in the quantity of fuel consumed from the electric network due to the joint production process for electric power and a distillation unit from type of Reverse osmosis for production of distillation water. Hence, the amount of saving in the fuel amount consumed in the electric network due to development of the basic design for the condensation steam station to a dual thermoelectric center allocated for production of electric power and distillation water: Whereas: BGT, NGT. The electric power produced (MW) and fuel consumption rate (ton/hr) for the gas turbine unit respectfully. NST. Electric power produced (MW) for the gas turbine unit in case of new operation system. (NEST), (BSB). Electric power produced (MW) and rate of fuel consumption (ton/hr) for the boiler in case of basic design of the station respectfully. NFP2 , NFP1.

Quantity of distillation water produced (ton/hr).Hence, the proper alternative is to give the maximum value for equation (1) (any alternative which has the studied design for distillation unit and gas turbine unit and so thermodynamic characteristics studied for this unit gives the maximum effectiveness possible via the amount of saving in the fuel quantity consumed to produce electric power and distillation water). It’s notice worth in the process of building the sport model for calculating the thermal design for the dual thermoelectric center, the thermoelectric centers calculation method is used [9], and method of calculating the gas turbine units of high primary thermal degrees for gases [10], and method of calculating steam boilers allocated for using secondary resources for power [11], and method of calculating the evaporating distillation units of multiple effects [12].

The amount of steam required for the steam turbine unit by an amount which is larger than the increase in the qualitative job of gas turbine unit.The effect of the properties of gas turbine unit on the quantity of steam produced in the two phases of the pressure of the boiler was also studied; where it was noted of figure (5) that, at a fixed ratio of air compression and an increase of initial temperature of gases, the amount of steam produced in the high- pressure stage of the boiler DSB1 is rising because of the increased amount of thermal power available to produce steam at this stage due to the high temperature gases after the gas turbine . It was also observed that the amount of steam produced in the phase of the low-pressure of boiler DSB2 is declined together with an increase of the initial temperature of gases before the gas turbine. The reason for this could be attributed to the low temperature of the combustion gases after the provider of high-pressure phase of the boiler as a result of increasing the amount of thermal power required to heat the feed water for such phase of the boiler. At the increase of the compression ratio of air temperature and fixing of the initial temperature of gases, it was observed of Figure (5) that the quantity of steam produced in the high-pressure stage of the boiler is declined, because of the low amount of thermal power available to produce steam at this stage. The quantity of steam produced in the low pressure phase of the boiler increases with higher ratio of air compression. The reason for this is due to the low amount of water needed to feed the high-pressure-phase of the boiler, and then the high temperature combustion gases after the provider of this stage of the boiler and thus an increase of the amount of thermal power available to produce steam in the low pressure phase of the boiler.The effect of vapor pressure prepared for PT desalination unit and efficiency of the compensatory EST plant for the production of electric power, as well as the rate of electrical power consumption for the production of desalinated water in the desalination unit of reverse osmosis type on the amount of savings of the quantity of fuel consumed DBST as shown in Figure 6, where it is noted the drop in the amount of savings of the quantity of fuel consumed (DBST1) together with an increase of steam pressure prepared for desalination unit in the case of recovery of the hydraulic power of water drained from the reverse osmosis unit (NRO = 6 kW.hr / ton). The reason for this is due to a drop in electrical power produced of the steam turbine unit (NST, (Figure 7) ) in a greater amount than the increase of the rate of consumption of electrical power of the compensatory desalination unit as a result of the high amount of desalinated water produced for the electro-thermal center (DDW, (Figure 7). In the case of non-recovery of hydraulic power for water drained from the desalination unit (NRO = 15 kW.hr / ton), it is observed of Figure 7 the high amount of savings of the quantity of fuel consumed (DBST2) together with an increase of steam pressure prepared for the desalination unit, because of the high rate of electrical power consumption for the production of desalinated water in the reverse osmosis unit, and then an increase of the rate of fuel consumption on the production of desalinated water in the separated production process in an amount that is greater than the rate of fuel consumption in the double electro-thermal center for the production of thermal power for the desalination unit. On fixing the vapor pressure prepared for the desalination unit and an increase of the efficiency of the compensatory desalination plant, it is noted of Figure (6) that the amount of savings of the quantity of fuel consumed is declined because of the low rate of fuel consumption for the production of electric power in the compensatory station. The effect of vapor pressure prepared for desalination unit PT on the designed number of effects of desalination unit N as shown in Figure 7; where it is noted that an increase of steam pressure prepared for desalination unit leads to a rise in the designed number of effects of the desalination unit; and then the low rate of qualitative thermal power consumption of desalination unit (QR) as a result of the high amount of thermal power recovery of desalination unit, and therefore a high amount of desalinated water produced (DDW).

It is also noted of Figure (8) the increase of the amount of the decrease in the quantity of nitrogen oxides and carbon dioxide exposed to the surrounding environment with a high ratio of air compression in the gas turbine unit, because of the increase in the amount of electricity produced and the high efficiency of the double electro-thermal center for production of this power, and then an increase in the fuel consumption rate for production of electric power in the compensatory unit which leads to an increase in the amount of combustion gases exposed to the surrounding environment in the separate production process of electric power and desalinated water.Figure (8) also shows environmental effectiveness of the use of gas turbine units of sequential combustion.
