MONTREAL — Xebec Adsorption Inc. is now operating its first commercial landfill gas to CNG upgrading system in Anshan, North Eastern China, which will deliver low carbon fuel to taxi fleets.

Xebec, a provider of gas purification and filtration solutions based in Montreal, said the upgrading system is based on the company’s fast cycle pressure swing adsorption technology.

The system was assembled and integrated at Xebec’s Shanghai facility and is operating within a variable pressure envelope of 90 to 120 psig with dynamic feed flow between 500 and 1,300 m3/h.

Xebec is also deploying a kinetic adsorption process to continuously remove varying amounts of nitrogen and oxygen, while maintaining corresponding recovery rates of 83% to 91%, and product gas purity levels of 94% to 98.6% methane.

The compressed natural gas will be used to power natural gas taxis that operate in the Anshan.
