The presence of siloxanes in landfill gas (LFG) and other bio-gases is extremely harmful to engines, micro-turbines, and other combustion equipment.  Many gas treatment processes designed to remove these contaminants use silica gel beads to adsorb siloxanes.  We are pleased to offer operators of waste-gas-to-energy facilities replacement silica gel in 2-5 mm beads, suited for siloxane removal.  Contact us for pricing and availability.
