Air Products receives PED certification for biogas membrane separators

Air Products' Prism membranes division in St. Louis, US, has received Pressure Equipment Directive (PED) certification from DNV GL Business Assurance Italia 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 pressurised equipment,’ says biogas business manager, Greg Malcolm.

Air Products' Prism membrane separators are manufactured exclusively at its facility in St. Louis.

The biogas separators contain polymeric hollow fibres that use selective permeation to separate biogas into two enriched streams of biomethane and carbon dioxide.
