Evonik Corporation today released the results of its first U.S. landfill biogas upgrading installation at Enerdyne’s large scale biomethane production facility at Lawrence, Kansas.
Since May, the plant has been running a membrane system to remove carbon dioxide at 1,600 standard cubic feet per meter (scfm) feed flow with low (2%) methane slip. Besides desulfurization and water removal, the facility operates with a proprietary system to remove VOC’s, siloxanes, oxygen and moisture which was designed and fabricated by Advanced Biogas Systems, an affiliate of Enerdyne.
