The Lubrizol Corporation has introduced Lubrizol SG9L60, a new 4-stroke, low ash, zinc-free stationary gas additive technology designed to significantly reduce the negative effects of siloxanes in landfill applications.

According to the Wickliffe, Ohio-based additive maker Lubrizol SG9L60 is the first industry marketed, specialty product specifically formulated and tested to reduce downtime in landfill engines, which enables oil marketers to meet the lubrication requirements of the demanding landfill market.

Variations in landfill gas composition present unique hardware challenges in the stationary gas industry due to siloxane concentration build up. Current practices include the removal of siloxanes from the gas before they reach the engine and the mechanical removal of silica deposits from the engine. Both these practices result in costly and frequent engine operational downtime.

The new Lubrizol SG9L60 technology offers a lubricant solution to the siloxane problem by controlling the size of silica particles, allowing them to stay dispersed in the oil, rather than depositing on engine parts.

“We identified an industry need via our landfill contacts for a lubricant solution that could reduce silica deposit formation to deliver enhanced performance to reduce overall maintenance requirements and labor costs,” said Al Haas, Lubrizol global product manager, Stationary Natural Gas.”Lubrizol is committed to working with our OEM and industry contacts in the landfill market to understand their needs and deliver dedicated, application-specific lubricant solutions like Lubrizol SG9L60, which provide engine durability benefits and overall maintenance cost savings.”
