Brea, California Gas Conditioning System

Location: Olinda Landfill; Brea, California

Project Scope

Venture was contracted to provide its patent pending Biogas Conditioning System to improve the quality of the Landfill Gas at the Olinda Landfill Gas to Energy (LFGTE) facility located in Brea, California. The LFGTE facility will use approximately 11,500 scfm of landfill gas to produce approximately 32.5MW of power using four (4) Solar Taurus 60 Gas Turbine Generators with HRSGs. The Biogas Conditioning System will remove landfill gas contaminants including NMOCs, Siloxanes and moisture, prior to combustion in the turbines. 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, high pressure, two vessel regenerable Gas Conditioning Skid and a carbon polishing skid.

The carbon polishing skid is used to assure long term, high siloxane removal efficiencies. The carbon polishing skid will operate in a lead / lag manner using manual valves and will only be used a few months of a year.
