Method of removing organic contaminants

摘要

A method of removing organic contaminants from a process gas such as raw, untreated landfill gas is disclosed. The steps involve collecting the process gas that includes organic contaminants for removal. An absorption liquid such as a terpene, is injected as a mist into the process gas to form a two-state absorption liquid and process gas fluid. The two-state absorption liquid and gas fluid communicates through a heat exchange module for absorption of organic contaminants in the process gas by the absorption liquid resulting in a cleaned process gas. The absorption liquid then is separated from the cleaned process gas.
