AN INTRODUCTION TO FAUJI FERTILIZER BIN QASIM
LIMITED
FFBL is one of the largest granular Urea and Dap fertilizer complex in Pakistan,
built at the cost of US$469 Million in November 1993, located in Eastern Zone of
Bin Qasim. The plant is approximately 45km south east to Karachi City and it is
connected to National High way. FFBL is one and only Fertilizer complex in the
Pakistan producing DAP (DI‐ AMMONIUM PHOSPHATE). It is the sole producer of
Urea and Dap in the country and forms part of Fauji group, one of the largest
conglomerates of Pakistan. FFBL and FFC jointly holds 63% of Urea and 51% of
DAP share of Pakistani fertilizer market. FFBL increases its product capacity which
is higher than the designed parameters. There are many features of FFBL that
make it distinct from any other Fertilizer complex in Pakistan.

with FFC (30%), FF (10%) and JPMC (10%) as main sponsors. The company
was formally listed with stock exchanges in May 1996 and commercial
production commenced wef Jan 2000. However, it continued to run in
crises due to technical, financial and managerial reasons till 2001. DAP
Plant brought to suspension in 2001 due to accumulated loss of Rs. 6.5
Billion. It resumed production in Sep 2003, after a lapse of 2 years.
 Renamed as Fauji Fertilizer Bin Qasim Ltd. (FFBL) in 2003, as such Jordan
Phosphate Mines Co. (JPMC) had sold its entire equity in the company.
Accordingly Phosphoric acid supply agreement with Jordan was
terminated. The company turned out to be profitable after 3 years i.e, by
2004 and declared 'maiden dividend' in 2004. Profitability has constantly
been on the rise since then and 2007 has been the most profitable year of
the company.

Utilities Plant
Utility plant provides the facilities to other plants to operate well and
continuously.
For that purpose, it is including the following equipment and machinery:
 Cooling tower
 Power generation
 Filtration of water
 Supply of water and steam for the whole plant
 Chillers and HVAC
 Compressed air for whole plant
 Demin water, hot water
 Natural gas distribution

 Raw water storage
 Fire water
 Potable water
Explanation
First of fall we take raw water from Pakistan steel mill and kinder lake. Raw water
storage consists of two parts. First part is use for steam and other part use for
emergency fire water. First part has 85000 m. cube and second Part is 5000 m.
cube.
Then raw send to 3 lines. First line goes to FPCL (fuji power company limited).
second line goes to ROp Plant (reverse osmosis) and third line goes to CLarifier.
Now in clarifier .... consist of 4 zone First fast mixing. second slow mixing third
sedimentation and 4 collectors. In calarifier we use dozing of polymer, hypo,
Alum. We use dozing of Alum and polymer when turbidity of raw water is very
high. Dozing of alam and polymer is in pipe lines .and the dozing of hypo is inside
the calarifier. * WHYDOZING OF HYPO IS INSIDE AND ALUM AND POLYMER IS
OUTSIDE OR IN PIPE LINE? ANSWER IS THAT when we use Alum and polymer, we
use mixer to mix it and in pipe line they mix each other. The purpose of Alum and
polymer is to Convert the small particles into big and polymer became it bigger...
So, the big particles separate down.
Then its goes to the two portion first cooling Tower and second sand filteration
Now we will discuss the major areas of utilities in detail.
Cooling tower
Cooling tower is basically used for cooling hot water coming from the plant of
urea or any other also using in the heat exchanger. For this purpose hot water is
injected from the top of the cooling tower and there are fans at the top of cooling
tower. Air from the fan passes through the hot water and takes heat, so
temperature of water will decrease from 43 c to 33 c. Total time of flow of water
is about 15 minutes. There are 10 cooling towers; 3 for Ammonia, 3 for DAP and
3 for Urea and 1 is on standby.

Power Generation
For power generation in FFBL there are 2 gas turbines and one diesel generator
(in emergency). The capacity of power generation of one gas turbine is 26 MW.
The power is generated at 60 Hz and the voltage is 13800 volts.
Power Distribution
The Power generated by the two gas turbines is directly fed on to the bus bars at
13.8 kV. The two bus bar are connected by tie breakers, which are normally open.
If one of the gas turbine trips, then the tie breakers connect the two bus bars and
thus load is taken by the other turbine. Between the two bus bars is a Diesel
Driven Emergency generator of 2MW, which comes into action in case of
emergency. The output of these feeders are distributed to the whole plant as
under and then at other side there is a step down tranformer that make a certain
desireable voltage level
1 Residential Workshop 2 Urea 8 Ammonia 2 Bagging 2 DAP 2 Colling Tower
2 ROU 2 Utilities
Diesel driven emergency generator:
It is used if the gas turbines stop working and is used to stop the plant from
shutting down. It automatically switches on in 20 seconds and has the capacity to
operate the plants until the gas turbines come back online.
 Air compressors
There are three air compressors in FFBL under the utility section which provide,
supply and generate compressed air known as instrument air and service air. The
compressors are screw type PD compressors that use a dry paper type filter.
The compressors have 2 stages:
1st
stage – 9000 RPM
2nd
stage – 14000 RPM

 Steam Production
The production and supply of steam to the whole plant is under utility section.
Steam is generated by two methods
Heat recovery steam generation
Auxiliary boiler
Auxiliary Boiler:
Auxiliary boilers are used for maintaining the variation in the steam production. In
this forced drafts fans are used to provide combustion air in the burner. It is water
tube type. The components of an auxiliary boiler are:
Steam drum
Water drum
Boiler tube
Inner casing
Outer casing
Refractory
Tiles
EMERGENCY LOAD SHEDDING SYSTEM (ELSS):
INTRODUCTION: It is a system that is responsible to provide power or electricity
to the whole plant in case of any emergency this system is programmed to
provide power to the most critical areas like ammonia. EXPLANATION: It is a plc
and dcs combined control system that are interlinked and programmed to provide
power priority wise like if their is shortage of power then it will switch of power of
residential area then workshop and etc its main job is to power up the most
critical areas like at ammonia plant hydrogen tank , chlorine tank etc Super
heaters.

Diammonium Phosphate (DAP) Process
The DAP plant design is based on double pipe reactor(DPR)AZF process from
Grande Paroisse, France Commissioned in November 1988. DAP Plant design
capacity is 2200MT/DAY and actual is 2450 MT/DAY.

Inputs:
Ammonia
Sulphuric acid
Phosphoric acid
Sand
Output:
DAP granules
Procedure:
• Ammonia, sulphuric acid and phosphoric acid added in the pre neutralizer.
This forms the slurry.
• The slurry is added along with sand to the granulator. Here grains are
formed by simple mixing.
• The grains are then moved to the dryer where it is dried at 90oC for 2
minutes. The heat is provided by the hot gas generator which maintains
the temperature.
• Then with the help of belts
this is fed to the vibratory
feeder for screening.
• Only 1/3rd are on size and
are moved to the de dusting
section De dusting is done to
remove large lumps.
• Scrubbing is also done to
absorb ammonia by water.
• The oversize grain, undersize
grain and ammonia water are
all recycled.

Urea Process
There are two
sections in Urea
plant
1. Urea Wet
2. Urea Dry
Urea wet section
designed based on
CO2 Stripping
process of
Stamicarbon,
Netherlands and
Urea Dry section
designed is based on the Fluidized Bed
Granulation technology from
Hydro Fertilizer Technology
(HFT), Belgium. Comissioned in
April, 1999 Urea Plant`s design
capacity is 1670 MT/Day and
actual is 1900 MT/Day.
Raw Material:
• Ammonia
• Carbon Dioxide

Ammonia Process
Ammonia Plant is the heart of FFBL or any other fertilizer company because this
plant is responsible for Ammonia production and also Carbon Dioxide which is
used in the manufacturing of Urea or in other words a shutdown of ammonia
plant means a shutdown of whole fertilizer company. Following are the names of
some of the major equipment under ammonia plant.
• Furnace (Primary Reformer).
• Secondary Reformer.
• Heat Exchangers (Shell & Tube, Flat Plate, Finned Type).
• Boiler.
• Startup Furnace.
• Startup Heater and many more.
Inputs:
• Natural gas
• Air
• Steam
Outputs:
• Ammonia
• Carbon dioxide
PROCEDURE:
• Desulphurization of natural gas.
• Crack natural gas in steam to produce hydrogen.
• Remove oxygen from air to give nitrogen in secondary reformer.
• Cool nitrogen and hydrogen in heat exchanger.

• Steam is removed and temperature elevated to 400-600 oC.
• 2N2 + 3H2= 2NH3
• Liquid ammonia is produced.
Equipment’s Of Urea, DAP And Ammonia & Their Function
Scrubber
It is a high pressure vessel where liquid ammonia is stored under pressure. It is an
efficient non-corrosive alloy which can handle liquid Urea for a long time. It
separates reactive and non-reactive gases. Scrubbers can also be used for heat
recovery from hot gases by flue-gas condensation.

Reactor
It is a type of heat exchanger. In this horizontal type of reactor ammonia and
carbon dioxide react with each other to produce Urea. It has tubes inside filled
with steam.
Columns
It is a high pressure vessel for mixing and separating the things. Different type of
processes takes place in it at a time.
Pipes
They are the close conduits in which the fluid flows. They are designed to bear
only the internal pressure. For a pipe we define two things”
Nominal pipe size (NPS) , usually the outer diameter of the pipe
Wall thickness on some standard e.g. 5,10,25,STD,XS,XXS
Tubes
The only difference b/w a pipe and a tube is, tubes are designed to bear both
internal and external pressure of the fluid. In tubes we exactly define the
thickness.
Heat Exchangers
Heat exchangers are used to transfer heat from one media to other media. They
are classified on different basis.
Types of Exchanger
 Plate type
 Shell and tube type
Plate type: A plate heat exchanger is a type of heat exchanger that uses metal
plates to transfer heat between two fluids. This has a major advantage over a
conventional heat exchanger in that the fluids are exposed to a much larger
surface area because the fluids spread out over the plates.

Shell and Tube Type: A shell and tube heat exchanger is a class of heat
exchanger designs. It is suited for higher-pressure applications. As its name
implies, this type of heat exchanger consists of a shell (a large pressure vessel)
with a bundle of tubes inside it. One fluid runs through the tubes, and another
fluid flows over the tubes (through the shell) to transfer heat between the two
fluids. The set of tubes is called a tube bundle, and may be composed of several
types of tubes: plain, longitudinally finned, etc.
Baffles: These are panels responsible for obstructing and redirecting the flow of
fluid in the shell side of an exchanger. They are situated normal to the walls of the
shell and force the liquid to flow at right angles to the axis of the tubes.
Valves
A valve is a device that regulates, directs or controls the flow of a fluid (gases,
liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing
various passageways. In an open valve, fluid flows in a direction from higher
pressure to lower pressure.
The Gate Valve: The gate valve is a general service valve used primarily for on -
off, non-throttling service. The valve is closed by a flat face, vertical disc, or gate
that slides down through the valve to block the flow.
The Globe Valve: The globe valve effects closure by a plug with a flat or convex
bottom lowered onto a matching horizontal seat located in the center of the
valve. Raising the plug opens the valve, allowing fluid flow. The globe valve is used
for on - off service and handles throttling applications.
The Pinch Valve: The pinch valve is particularly suited for applications of
slurries or liquids with large amounts of suspended solids. It seals by means of
one or more flexible elements, such as a rubber tube, that can be pinched to shut
off flow.
The Ball Valve: The ball valve is similar in concept to the plug valve but uses a
rotating ball with a hole through it that allows straight-through flow in the open
position and shuts off flow when the ball is rotated 90 degrees to block the flow
passage. It is used for on-off and throttling services.

The Butterfly Valve: The butterfly valve controls flow by using a circular disc
or vane with its pivot axis at right angles to the direction of flow in the pipe. The
butterfly valve is used both for on-off and throttling services.
The Check Valve: The check valve is designed to prevent backflow. Fluid flow
in the desired direction opens the valve, while backflow forces the valve closed.
Fabrication Shop
Valve testing methods
There are three types of valve testing in fabrication shop.
Seat test
Back seat test
Shell test
Scaffolding
Scaffolding is under fabrication shop. Its purpose is to provide temporary working
condition to work at some height by joining pipes. There are about three types of
pipe joint we see in scaffolding area in which there are
Swivel joint
Spigot joint
Fix joint
Welding in fabrication shop
Gas cutting area:
For gas cutting acetylene cylinder and oxygen cylinder are used. When acetylene
burns with oxygen then it creates high temperature flame that can cut metals. To
check the percentage of oxygen and acetylene colour of flame is very important.
Yellow colour indicates reducing flame and blue colour indicate oxidizing flame.

Plasma cutting:
In plasma cutting plasma gas is used. Its flame temperature is higher than the gas
cutting flame. It has advantage that its flame is not oxidizing flame and so it can
be used for cutting of aluminum also. There are two machines in fabrication shop
for plasma welding. One has capacity to cut of thick 0 to 6mm and other has 0 to
32mm.
Arc welding:
Arc welding in fabrication shop are SMAW and GTAW. The difference between
SMAW and GTAW is that for shielding purpose tungsten gas is used in GTAW
while in SMAW on electrode there is coting which melt and create a gas shielding
area which protect weld bead from oxygen.
Machine Shop
Machine shop has a number of machines used for different purposes. They
include:
Lathe machines: A lathe is a machine tool which rotates the workpiece on its
axis to perform various operations such as cutting, sanding, knurling, drilling, or
deformation, facing, turning, with tools that are applied to the workpiece to
create an object which has symmetry about an axis of rotation. There are 3 types
of lathe machines in the machine shop; small duty lathe, medium duty lathe and
heavy duty lathe machine.
Drilling machine: A machine for making holes with removal of chips. Drilling
machines are used for drilling, boring, countersinking, reaming, and tapping.
Radial drilling machine: A radial drilling machine or radial arm press is a
geared drill head that is mounted on an arm assembly that can be moved around
to the extent of its arm reach.
Milling machine: Milling is the machining process of using rotary cutters to
remove material from a workpiece advancing (or feeding) in a direction at an
angle with the axis of the tool.

Balancing machine: A balancing machine is a measuring tool used for
balancing rotating machine parts such as rotors for electric motors, fans, turbines,
disc brakes, disc drives, propellers and pumps. The machine usually consists of
two rigid pedestals, with suspension and bearings on top supporting a mounting
platform. The unit under test is bolted to the platform and is rotated either with a
belt-, air-, or end-drive. As the part is rotated, the vibration in the suspension is
detected with sensors and that information is used to determine the amount of
unbalance in the part. Along with phase information, the machine can determine
how much and where to add weights to balance the part.
Motor Vehicle Shop
In automobile section of FFBL there are 3 cranes , one crane mounted belt load
truck, oil tankers and loaders. In cranes one crane has load capacity of 55ton,
other two have 20ton. They are hydrocrane, with 6 cylider v type engine. Load
chart of crane depend upon the radius, angle and boom of the crane. If crane
have minimum radius, minimum angle and minimum boom length then crane can
carry maximum load. Crane mounted belt truck have crane that can carry about
20 ton weight.
Machinery at Urea, DAP and Ammonia Plant & Their
Function
This includes the moving parts of the plant. Their summary is as follows:
• Compressors:
Compressors are used to flow fluid (gases) from one place at plant to other
and also to raise their pressure. They are of two types on basis of classification.
1. Verticle compressor
2.Horizontal Compressor
Also they are sub-divided into various types:

1. Radial flow(Centrifugal) compressor:
These compressors are used for medium flow and pressure. In FFBL plantsite
mainly these compressors are installed. These are dynamic compressors.
2.Axial Flow Compressors:
These compressors are uesd where low pressure but comparatively high flow is
required such as in gas turbines. In plantsite, all gas turbines have multistage axia
flow compressors. These are also dynamic compressors.
3.Positive Displacement Compressors:
These are uesd where low flow but high pressure is required.
• Pumps:
Pumps have the same functions as of compressors, instead their working fluid is
liquid. In plantsite positive displacement pumps are installed in lubrication oil
circuits to make sure the constant supply of lub oil to compressors, turbines,
bearings and other varios machines.The types of pump impellers are open
impeller, partially closed impeller and closed impeller. In pumps there are steam
turbine pumps which are run by steam turbines.
• Steam turbines:
Steam turbines are installed in many places. These are running pumps and
motors etc. These are powered by steam producing by boilor.
• Gas turbines
There are three gas turbines at plantsite. Two at the utilities and one at
synthesis gas.
The major components of a gas turbine are:
Self-cleaning type air filter
Multi-stage axial flow compressor
Combustion system

Closed forced lubricating oil system
Diesel engine storage system
Natural gas firing system
Fire detection and co
protection system
Seismic type vibration system
Thermo couples for measuring critical turbine temperature
• Couplings:
The two types of coupling are mechanical and hydraulic. The advantage of
hydraulic coupling over mechanical is that there are no jerks. Thermal plug and
fuse plug are two methods for the safety of the coupling.
• Dynamic Sealings:
These kind of sealings are used to seal different stages in compressors or
pumps to maintain pressure. These are of variuos types:
Labyrith Seals
Oil floating seals
Dry gas seals
• Bearings:
As by name it is clear, bearings are used to bear loads and also helps in smooth
running. On basis of classification they are two types
Axial bearing also called thrust bearing.
