The entrainment of hydrogen sulfide (H2S) and siloxanes within landfill gas poses significant challenges to operating landfill gas-to-energy (LFGTE) facilities. Installation of H2S and siloxane removal systems is becoming increasingly common, being highlighted by the need to extend generator maintenance intervals and/or meet environmental quality requirements for back end emissions reductions. There are many H2S and siloxane removal technologies available in today's landfill gas industry. Each technology presents their own unique pros, cons and challenges.

Following this presentation, participants will be able to:

• Gain a broad view of available H2S and Siloxane removal systems
• Understand the pros, cons, and challenges with available systems
• Understand the conclusions reached in specific reference to the Coffin Butte Resource Project
