‘Game-Changer’ as a Novel Adsorption/Desorption Cycle Yields
‘Recovery Rates of Up to 98.5% While Operating at Low Pressure’

Xebec Adsorption is promoting an improved pressure swing adsorption architecture for upgrading biogas to biomethane. By optimizing fast-cycle PSA technology process design “and combining it with a novel adsorption/desorption cycle,” states a release, “Xebec can now achieve recovery rates of up to 98.5% while operating at low pressure, allowing operators to maximize revenue, lower operating costs and, consequently, increase profitability.”

The result is more practical RNG – renewable natural gas.

Xebec PSA/pressure swing adsorption equipment at work in France. Installations employing the company’s new fast-cycle designs in Europe are already achieving the new performance levels – stated at 98.5% recovery – for biogas-to-RNG upgrading, the company says.

Xebec notes that it pioneered fast- and rapid-cycle adsorption technology, bringing its proprietary technology to the biogas upgrading market more than 15 years ago. Today the Montreal-based company “is a major player with 27 installations operating globally and a growing number of ongoing projects under planning, procurement and construction.”

‘Flexible, Reliable, and Cost-Effective… a Step Change’

Biogas upgrading, the firm says, is an engineering and process design challenge “because gas compositions constantly vary, flow rates fluctuate, and temperatures change with seasonal and weather conditions.

“Operators need technology solutions that are flexible, reliable, and cost-effective in order to maximize profits,” Xebec says, claiming “a sterling reputation for delivering product gas that meets all of these objectives at a quality that can be injected into the pipeline systems.”

PSA recovery rates typically deliver recoveries in the 94% to 96% range, Xebec says. “With this breakthrough in the PSA process and cycle design, Xebec can offer a step change in achievable recovery rates, up to 98.5%, offering its proven adsorption technology that is cost effective, flexible and highly reliable.”

‘This Is a Game-Changer… Product Gas that Can Be Sold’

“This is a game-changer for Xebec,” Xebec president and CEO Kurt Sorschak says in a release. “Our customers have always been highly complementary of our robust and flexible systems that can adjust within minutes to changing operating conditions while continuously delivering quality product gas that can be sold.

“With this improvement in recovery to 98.5%,” Sorschak says, “we are now offering clear economic advantages to our customers. Xebec combines high recovery with low operating costs and unrivaled system tolerance and flexibility, resulting in increased profitability for our customers.

Game Changer at ACT Expo Too

“With 21 projects in our current pipeline,” he said, “customers have clearly taken to Xebec’s new biogas upgrading solution.”

Separately, organizers of the Advanced Clean Transportation (ACT) Expo and conference fast approaching in Long Beach, Calif. will examine the merits of biomethane at the Game Changer 2.0 Summit session on Monday, May 1. ACT Expo itself runs May 1-4, with the exhibit hall open May 2-3.

Xebec Adsorption will be at Booth 553.
