Biogas to Energy
The engineering team at Willexa Energy has been providing quality gas treatment solutions to the biogas industry for more than 20 years. With a focus on protecting engines, turbines, cataysts, micro-turbines, fuel cells, or boilers from the contaminants found in landfill and digester gas, our equipment can be found on biogas to energy projects across the country.
Our filtration, chilling & dehydration, and VOC & siloxane reduction solutions will not only decrease your operating costs, they will increase your efficiency and uptime.
Got post combustion exhaust catalysts? No problem. We offer guaranteed catalyst protection from VOCs and siloxanes while significantly improving the profitability of your landfill or digester gas to energy project.

Reciprocating Engines
Reducing siloxanes in the fuel gas for your reciprocating engines will eliminate silicone dioxide build up as a cause of maintenance, significantly reducing the frequency of oil changes, spark plug changes, top end overhauls and parts failures. It will also maximize engine efficiency and uptime, increasing power production and project revenue.
Gas Turbines
Siloxane build up in a gas turbine will significantly reduce efficiency over time, fouling nozzles and recuperators, and leading to frequent and expensive overhauls. Siloxane reduction eliminates siloxane related maintenance and keeps your turbine operating at peak efficiency, minimizing costs and maximizing profits.
Exhaust Catalysts
Left untreated, siloxanes can destroy an exhaust catalyst in a matter of hours, so when post combustion catalysts are required for emissions control, reliable and verifiable siloxane reduction is a necessity. Two stages of siloxane treatment with interstage sample ports ensures siloxane levels remain below detectable limits, providing guaranteed catalyst protection.
Microturbines & Fuel Cells
Siloxanes can cause rapid failure of a microturbine or fuel cell if left untreated. Even levels of a few ppb have been found to lead to rapid deposits and failure. Our two stage systems will ensure siloxane levels remain below detectable limits providing guaranteed protection and worry free operation.
Boilers
Siloxane buildup in a landfill or digester gas fueled boiler will coat internal surfaces and foul burner tips, significantly reducing heat transfer efficiency. Just one overhaul of your boiler to remove siloxane related build up can more than pay for a regenerative siloxane reduction system. Consider it an insurance policy - and a smart investment.
