Air Products’ (Lehigh Valley, Pa.; www.airproducts.com) Prism Membranes division in St. Louis, Missouri, has received Pressure Equipment Directive (PED) certification from DNV GL Business Assurance Italia S.r.l. for its newest line of biogas membrane separators.
“This certification confirms that our biogas separation product meets the European standards for design, manufacture and safe operation of pressurized equipment,” says Biogas business manager, Greg Malcolm. “Air Products is a leading manufacturer of gas separation membranes, and this certification builds on our commitment to the European biogas market.”
Air Products’ Prism Membrane Separators are manufactured exclusively at its facility in St. Louis. The biogas separators contain polymeric hollow fibers that use selective permeation to separate biogas into two enriched streams of biomethane and carbon dioxide.
