Introduction
History
CHEMTRON was founded in 1988. It started with the demand from the operators of Power Plants for a
high-performance compressor cleaning system. This should consist of a nozzle system and a full automatic
supply system, which should be usable from the control room. Together with the hardware we have been
asked to supply also a high efficiency cleaning solution.
The development and manufacturing of the compressor cleaning system VRA-lll-E in its latest state of
development arises from a long-term of experience with different manual systems, cleaning solutions and
on the basis of a pool of experienced engineers.
The VRA-lll-E is the most effective compressor cleaning system in the whole world and installed in more
than 100 Power Plants.
Performance profile
The founder of Chemtron possesses over 40 years’ experience in the development and manufacturing of
our VRA-lll-E and VRA-1 skid units, nozzle systems, as well as in our cleaning agents. In addition, we also
carry out chemical-technical cleaning and pickling in power stations, refineries and industrial plants. Here
we use our additives and industrial cleaning products.
Our products are used with great success both in Germany and abroad, for example in:
Waste-fired power stations
Oil- and coal-fired steam boiler plants
Tyre factories
Chemical factories
Our product and service program
The function of the compressor cleaning system is to clean the compressor of the turbine in OFF-LINE use
and to hold the maximum compressor power in ON-LINE use.
Due to pollution for example thru pollen, subtle particles and aerosol on the blades, the flow cross-section
is altered.
The fouling on the blades are acid and following elements are contained in the covering: Si, Ti, Ca, Mg, Al,
Iron and sulphur.
Because of these pollutions, there is a decrease of power.
This is the point where we interfere with our compressor cleaning system and our detergents.

Compressor cleaning agent
ChemTurbo OL/Siwash S
Is a solvent-based detergent that grants a maximum cleaning-effect for ON-LINE and OFF-LINE
cleaning. Siwash S removes all the contamination on the turbine blades. The compressor cleaning
products are in use on the market very successful and appreciated by all customers.
Chem-Antifreeze/Si-Antifreeze
Prevents the icing of the compressor inlet. It is mixable with water in any
ratio. No bonding or contamination of the turbine blade surfaces.
The range of use is from +8° C down to -35°C air intake temperature.
ChemTurbo OL-W/Siwash W
Is a water-based detergent. The wet fluid contacts the fouled surface,
the solution then penetrates the porous matrix and dissolves it.
It cannot be used in combination with Si-Antifreeze.
Siemens Erlangen has approved all products. We are a certified partner with them. Siemens also
invented their own Brand name for our products, beginning with “Si”.
The results obtained with ChemTurbo OL/Siwash S and ChemTurbo OL/Siwash W is well inside those
required in the specifications of all other manufacturers so that approval can be obtained
immediately without any problem.
Advantages:
° No reduction in output during ON-LINE cleaning
° Better fuel utilization
° No requirement to shut the compressor down for cleaning at regular intervals
° Very high availability of the gas turbines
° Fully automatic cleaning sequence
° No pulsing of the washing solution
° Excellent distribution of the washing solution in the bell mouth
° Maximum possible cleaning effect
° Injecting in under full load
° No damage to material and coatings

Mobile Compressor Cleaning Package
The compressor-cleaning package is required to supply the cleaning fluid used for compressor
washing to the cleaning nozzles. It essentially comprises a pressure boost station and associated
components.
The package is mounted on a frame constructed of steel sections and designed as a transport cart so that
it can be used for several gas turbines. The most important components of the compressor cleaning
package are centrifugal pump MBA18 AP001 and tank MBA18 BB002. To enable the mixing of
demineralized water (deionized water) with a cleaning agent to a homogeneous cleaning fluid, circulation
of the cleaning solution shall be provided.
Therefore a branch piping with isolation valve has to be included, starting after the pump and leading
back into the tank. Demineralized water is filled into the tank from an existing demineralized water line;
the cleaning agent is dosed to the cleaning package tank from a storage tank using a hand drum pump
(MBA18 AP002). During the cleaning operation the centrifugal pump forwards the cleaning fluid at a
pressure of at least 6 bar (g) through a flexiblehose line to the respective nozzle system.

Description of the VRA-lll-E ACCS-Skid (Advanced Compressor Cleaning
Skid) for ON- and OFF-Line Use
Comprises of:
Construction Module
and Drip Pan Unit including IBCs for
ChemTurbo-OL/Siwash S and Chem
Antifreeze/Si-Antifreeze
It is possible to choose either
200 litre Barrels
or
1.000 litre IBCs for
the Drip Pan Unit.
The connection
between the Drip
Pan Unit and the Construction Module will be
constructed via
Hose Line and Quick Coupling
Basically the Construction Module comprises of
a Frame Construction with included 1.000 litre
Mixing Tank, Feed Pump, Filling Pump, Tubing,
Fittings with pneum. impulse and Control Cabinet with Touch Panel and S7-SPS or VIPA 300S.

Electrical Connection: TN-S Net, 415 V, 50 Hz, 9,5 kW or specific to the Country
Signal exchange with the control room – the construction module will be remote controlled from here.
Option:
The Construction Module can be controlled from another room through an additional
control panel.
Compressor Cleaning:
According to the type and intake temperature the cleaning fluid consisting of VE-Water, ChemTurbo-OL/Siwash S
and Chem Antifreeze/Si-Antifreeze will be prepared in the mixing tank and afterwards injected with the nozzle
system by using the feed pump.
The cleaning programs are deposited in the SPS.
The admix of the Chem Antifreeze/Si-Antifreeze starts as soon as the temperature of the intake air drops under +8°C.
The Compressor Cleaning Cycle
We recommend a compressor ON-LINE cleaning daily and third day with the addition of our cleaning agent
ChemTurbo-OL/Siwash S or ChemTurbo-OL-W/Siwash-W.The fouling of the compressor can vary according to the
plant location, the use of cleaning agents ensures improved cleaning efficiency. Therefore, the operator can adjust
the cleaning cycle to the local site condition.
Recommended cleaning cycles
n.-Day n+1.-Day n+2.-Day
ON-Line
(demin. water with
1 cleaning agent added) --- ---
2 (demin. water)
OFF-Line: Once every 3 months, or at a suitable opportunity
