Abstract
A method of using a triple-effect absorption system to recover methane from landfill gas contaminated with COand trace contaminates such as chlorinated hydrocarbons and aromatics involves processing the landfill gas with three absorbers and a flash system. One absorber uses a solvent to absorb the trace contaminants from the landfill gas, the second absorber in conjunction with the flash system extracts COfrom the gas, and just a first portion of that COis used for stripping the trace contaminates from the solvent in the third absorber. The rest of the extracted COis vented to atmosphere to prevent dampening the combustion of the trace contaminants absorbed by the first portion of CO.
