Siloxanes are man made compounds that contain silicon, oxygen and metal. Siloxanes are used to manufacture personal hygiene, healthcare, and industrial products.  As a consequence of their widespread use, Siloxanes can be found in waste water and in solid waste deposited in landfills.

Evidence of Siloxanes in Bio-Gas is found in the form of a white powder and gas turbine hot section components.  It’s a light coating on various types of heat exchangers, deposits on combustion services, in reciprocating engines, and as a light coating on post combustion catalysts.

The white powder is primarily Silicon-Dioxide a product of Siloxane Combustion.   Micro-turbine and catalyst failures have brought great focus on siloxanes and the manufacturers of these combustion components look to Hengye, Inc to provide selective media that can be used to remove Siloxane.
