(Fleets & Fuels) Installation Combines Membrane and PSA Technologies Yielding Biomethane-Based CNG for Palm Oil Mill Vehicles — Canada’s Xebec Adsorption has delivered its first “hybrid” biogas upgrading plant, a unit combining membrane separation and fast-cycle PSA/pressure swing adsorption technologies to produce biomethane for natural gas vehicles in Malaysia.
The source of the biogas is POME – palm oil mill effluent – from a producer who will use the resulting biomethane to make compressed natural gas for local mill vehicles.
Fast cycle PSA technology is a robust and proven technology that automatically adapts to changing feed gas compositions while continuously maintaining product quality, Xebec says. “The combination with advanced polymer membranes allows for that robustness of operation to be paired with the added ability to boost recovery to levels unobtainable by PSA technology alone,” states a release.

“As for the CNG market in the U.S., we are somewhat pessimistic for 2016, given that the spread between diesel and CNG is virtually zero,” Sorschak says. “We think that the market in 2016 will only be about 40% to 50% of what it was in 2014,” he told F&F – “50 to 70 stations.”
