1) CHEMTRON provides compressor cleaning agents, systems, and services to reduce power loss in gas turbines caused by fouling. 2) Fouling from airborne particles can accumulate on turbine blades and surfaces, reducing efficiency and output by up to 3%. 3) CHEMTRON's products and cleaning systems help customers recoup this lost power output and extend maintenance cycles to save on fuel and other costs.

Chemtron since 1988.
Since 1990 we include Siemens as
one of our most important customers.
PREFACE:
Many power plant operators complain about the power loss because of fouling. They think it is
unavoidable. After all, even the best air filters still allow lots of micro particles and some dirt,
moisture and, in particular, hydrocarbon residues to pass through with little hindrance.
Hydrocarbon residues not only stick to the blades, but also allow the air contaminats - such as
hydrocarbons particles, chlorids and sulphors compounds, traffic pollutants, industrial pollutants,
air pollutants as iron and silicate, pollen to adhere to them much easier. The consequences are
rougher surfaces, higher turbulence levels, deteriorating flow patterns, reduced cross section of flow,
higher compressor outlet temperatures and lower compressor outlet pressures.
All this can quickly add up to a 3% loss of power.
For a 150 MW compressor, that means 5 MW decreased output and increased expences. All this can
be improved. That‘s what we work towards every day...

THE FOUR ELEMENTS OF
THE COMPRESSOR CLEANING
Delivery Skid
Control System
Nozzle System
Cleaning Fluid
CHEMTRON - all over the world
DESIGN OF NOZZLE SYSTEMS
Fact is that a fixed ratio of water to the fuel volume should not be exceeded. Our
nozzle system delivers the cleaning fluid in the required droplet size and distribution
into the intake stream. Only with our cleaning products can these criteria be achieved.
It is also possible to retrofit each gas turbine with a custom made designed nozzle system.

4. Siwash S/ChemTurbo OL
is a solvent based distillate and detergent. Distillates are strongly
lipophilic. They dissolve into the hydrocarbon contaminants, loosening
and softening them, and making them easier to dislodge by the action
of centrifugal force.
Si-Antifreeze/Chem-Antifreeze
range of use is from +8° C down to -35° C air intake temperature.
Prevents the icing of the compressor inlet. Mixable with water in any
ratio. No bonding or contamination of the turbine blade surfaces.
Siwash W/ChemTurbo OL-W
is a water based detergent. The wet fluid contacts the fouled surface,
the solution then penetrates the porous matrix and dissolves it.
Cannot be used in combination with Si-Antifreeze.
Water/Demineralized Water
Water, known as the “universal solvent,” can be used as a
cleaning agent, but it is an inefficient and risky choice. For
one thing, it cannot combine chemically with hydrocarbons,
the largest percentage of substances.
Under no circumstances should you use water that has not
been demineralized. Alkali and alkali earth compounds
as chlorides, fluorides and salts can cause a severe
damage to the turbine.
Product Applications
Our products are designed for use in industrial, aviation
and marine gas turbines of all sizes.
Cooling air ducts
Our products not only clean the internal surfaces of compressor,
but also clean the cooling air ducts inside the turbine blades.

air intake temperature
This system can supply up
to 6 Gas Turbines
max. 75 m pipeline length between
ACCS/VRA-III and Gas Turbine
ACCS/VRA-III CONTROL
Advanced Compressor
Cleaning System
Exchange of signals between ACCS/VRA-III
and plant control
The plant control starts the
cleaning process
The cleaning fluid is prepared in
the mixing tank
Cleaning fluid is then mixed with
demineralized water, Siwash S and
Si-Antifreeze if required
After this step, the plant control has to
start the injection of the cleaning fluid
When cleaning is complete, the piping
system is blown out by compressed air
Each program runs automatically

COST AND BENEFIT
Three ways of saving money with effective compressor cleaning
1. the gain in efficiency and output reduces direct costs for fuel, consumables,
labor, etc
2. for a typical gas turbine, the time between major overhauls can be extended
with regular compressor cleaning
3. regular cleaning will extend component life
