Description:
The report describes Phase II of a demonstration of the utilization of commercial phosphoric acid fuel cells to recover energy from landfill gas. This phase consisted primarily of the construction and testing of a Gas Pretreatment Unit (GPU) whose function is to remove those impurities from landfill gas which are detrimental to the fuel cell. The GPU has been successfully tested at a landfill in Los Angeles (Sun Valley), CA. The site is operated by Pacific Energy Corp. as a landfill-to-energy facility. The GPU successfully removed the sulfur and halogen compounds contained in the landfill gas to a level significantly below that specified for use with the phosphoric acid fuel cell. During a challenge test in which dichlorodifluoromethane (Refrigerant 12) was intentionally injected into the process stream during an 8-hour period, the exit concentration of the Refrigerant 12 was below the limit of detection and below the specified value for the fuel cell.
