LES owns and operates the Oklahoma City high Btu gas processing plant. The plant utilizes the Air Liquide Medal membrane gas separation system. The Oklahoma City landfill has over 10
millions tons in place and is owned by Waste Connections, Inc. The landfill receives waste from the Oklahoma City metro area. The projected life of the landfill extends beyond 2033. This plant is
continuously and economically converting landfill gas to pipeline quality (high-Btu) gas. This plant is one of smallest and most efficient high-Btu plants of its kind in operation. The Oklahoma City landfill is currently producing approximately 1,400 scfm of landfill gas. This is the equivalent of 1,100 MMBtu per day. The gas flows from both existing and planned wellfield/collection system expansion are projected to increase production to 1,800 scfm in 2010.
The plant has been in operation since May 2008. Processed (high-Btu) gas is delivered to the Southern Star pipeline and is sold to Westar. The 3.0 MMScfd gas facility processes the LFG by removing the water, H2S, and organic compounds. The process then removes the carbon dioxide in a 2 stage membrane separator. The processed gas is compressed and delivered to the Southern Star pipeline.
