Landfill Gas to Energy Project-Butte County, California

Location: Butte County, California
Date Completed: 2011

Project Scope

Venture Engineering & Construction was contracted to provide its patent pending Biogas Conditioning System to improve the quality of the Landfill Gas at this Landfill Gas to Energy (LFGTE) facility. The landfill uses approximately 1,000 scfm of landfill gas to produce approximately 2 MW of power using one (1) Jenbacher 616 engine.

The Biogas Conditioning System removes landfill gas contaminants including H2S NMOCs, Siloxanes , and moisture prior to combustion in the engines. These contaminants are harmful to all combustion devices as well as post combustion environmental control system catalysts (i.e. CO and SCRs). The Biogas Conditioning System at this facility includes our standard low pressure, two vessel regenerable Gas Conditioning Skid.

Design Basis

Inlet Conditions (Typical):
• Inlet: 1,000 scfm
• 10 psig
• = 75 mg/m3 siloxanes
• = 1500 ppmv H2S
• = 44?F dew point
• = 100?F
• = 2,000 ppmv NMOCs
• Outlet: =5 mg/m3, Si

Outlet (Typical):
• Siloxanes: = 75 ppbv, Si
• Dew Point: = 0F (24 hr avg.)
• NMOCs: = 750 mg/m3
