Fast-Cycle PSA Technology Supporting Fleets in Anshan

Montreal-based Xebec Adsorption says it’s supplied equipment for China’s first landfill gas upgrading installation, which is now supplying low carbon fuels to taxi fleets in Anshan.

The landfill gas upgrading system in northeast China is based on Xebec’s fast cycle PSA pressure swing adsorption technology. The equipment was assembled and integrated at Xebec’s Shanghai facility according to Chinese code and certification requirements, Xebec says.

The system operates within a variable-pressure envelope of 90 to 120 psig and dynamic feed flow parameters between 500 and 1300 cubic meters per hour. In addition to the PSA equipment, Xebec says it’s using 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.”

Xebec-logo“Xebec’s upgrading system performance is excellent, delivering gas quantities and qualities which are higher and purer than we expected. This allows us to sell more high quality gas to our customers, making this investment very attractive for us,” Mr. Luo Yong, chairman of Beijing Golden Green Environmental Engineering & Technology Company, the owner of the project, says in Xebec’s announcement.

‘Local Design and Manufacturing Capabilities’

“Xebec’s strong Chinese supply chain, with local design and manufacturing capabilities, have focused on maintaining high quality standards while still finding significant cost reduction of the overall upgrading system, complying with all local electrical, mechanical and safety regulations and certification requirements,” Xebec says.

“It has been extremely important for Xebec to establish this first reference operation in the landfill gas upgrading space,” said Xebec Shanghai GM Peter Cheng.

‘Exponentially Toward an Ecologically Sustainable Society’

“We can now demonstrate proven and reliable upgrading technology to potential Chinese customers.”

“China is committed to significantly reduce greenhouse gas emissions over the coming decades and needs technologies like Xebec’s that can provide tangible reductions in GHG emissions,” Cheng said. “Upgraded landfill gas used as transportation fuel has the lowest GHG emission profile of any transportation fuel available today, beating out electrical and hydrogen vehicles.”

“China has the potential to convert massive amounts of biogas and landfill gas into low carbon renewable natural gas which can then be utilized in a number of different applications,” Cheng added, “allowing China to move exponentially toward an ecologically sustainable society.”
