Hollow Fibers System Certified as Partners Sought for Commercialization

Air Products reports certification of its Prism brand hollow-fibers membrane system for helping separate the components of raw biogas to produce high-purity biomethane.

Air Products is seeking partners to incorporate its membrane separation units into biogas-to-biomethane processing systems.

Air Products’ Prism Membranes unit in St. Louis has received PED/pressure equipment directive certification from DNV GL Business Assurance Italia.

“This certification confirms that our biogas separation product meets the European standards for design, manufacture and safe operation of pressurized equipment,” biogas business manager Greg Malcolm said in a release. “This certification builds on our commitment to the European biogas market.”

Air Products Prism brand membrane biogas separators contain thousands of tiny hollow fibers. ‘Some gas molecules, like carbon dioxide and water vapor, permeate through the membrane walls while other molecules like methane are transported the length of the fibers and exit from the end of the separator,’ the company says, noting that the methane stream ‘is typically 97% to 99% pure when it exits the membrane separator.’

Selective Permeation

The Air Products biogas separators contain polymeric hollow fibers that apply selective permeation to separate biogas into two enriched streams of biomethane and carbon dioxide. They are manufactured in St Louis.

“We do not build the membrane systems at this time,” says sales and marketing manager Allie Douglass.

“We are looking for partners,” she told F&F, “who can incorporate the membrane upgrading system with what they provide…

“We focus our efforts on making the membrane the best one that there is on the market, and we leave the system engineering up to our partners.”
