Environmental Protection Agency - LMOP: LFG Energy Project Profiles Page 2 of 2 <br />The project utilizes several technologies to produce a gas that is clean, dry, and free of ~ <br />siloxanes and volatile organic compounds: <br />. SulfaTreat system removes hydrogen sulfide. A 40-foot shipping container was <br />modified to house 100,000 lbs. of clean-up media. <br />Pressure Swing Absorption (PSA) unit operates on much lower pressure than <br />traditional PSA systems. <br />. Air Liquid-MEDAL's membrane separation system removes 98 percent of the carbon <br />dioxide and approximately half of the remaining oxygen. <br />A 22,000 foot pipeline was constructed along a city right-of-way that passed through dense <br />residential development. Johnson City launched a public awareness campaign including <br />meetings, newspaper articles, and door hangers to keep citizens along the pipeline <br />informed. Today, the city and Waste Management operate an educational center at the <br />landfill. Storyboards show visitors how LFG is generated, collected, and processed into <br />nearly high Btu gas for steam and power generation. <br />Last Updated: 8/18/2008 <br />:• ~.
