System for removal of organic contaminants from bio-gas for renewable energy production

Abstract

A method of reducing siloxane contamination in an effluent gas is described, where one embodiment of the method comprises directing the effluent through a reactor comprising a dialkyl terminated glyme solvent having a molecular size less than about 300 Daltons, the dialkyl terminated glyme serving to physically absorb the siloxanes from the effluent; polymerizing the siloxanes by directing them through a packed bed of acidic resin catalyst media housed within the reactor and immersed within the solvent so as to create polymerized siloxanes having a molecular size greater than about 300 Daltons, that are soluble in the solvent; and separating the polymerized siloxanes from the solvent via nanofiltration; and recycling the solvent into the reactor for further physical absorption of incoming siloxanes.
