Volatile Methyl Siloxanes (VMS) in landfill and sewage gas convert into silicon dioxide as combustion takes place in the engine. Without an effective Siloxane Removal System, the silicon dioxide combines with other elements in the gas, and with the lubrication oil to form a hard matrix that accumulates on the combustion surfaces.
As the deposits accumulate, the engines efficiency falls causing detonation in the combustion chambers. The resultant unburned fuel contaminates the exhaust gas increasing emissions.
Volatile Methyl Siloxanes (VMS) are a class of chemicals widely used in personal care products, as effective cleaning agents of electronic circuitry and in the dry cleaning industry.
The waste from these industries is frequently disposed of in landfill sites. As organic matter decomposes it produces methane and carbon dioxide.
The Siloxanes blend with this and contaminate the gas which is used to fuel engines that produce electricity.
Various methods have been employed in an attempt reduce the effect of the silicon dioxide deposits in engines used by the landfill and sewage industries.
Fluid injection systems do allow the silicon matrix to soften making removal easier, however in the long term, the use of an effective Siloxane Removal System is preferable before the gas reaches the engine preventing the formation of deposits and reducing maintenance & operating costs.
