Air Products secures PED certification for two new sizes of biogas membrane separators


International certification body DNV GL Business Assurance Italia has awarded Pressure Equipment Directive (PED) certification to Air products' two new sizes of membrane separators for biogas upgrading applications.

The new membrane separators have been developed by Air Products' PRISM Membranes division, located in Saint Louis, Missouri, US.

The certification has been granted after Air Products' new biogas separators were found to have fulfilled the requirements of European standards for design and manufacture, as well as safe operation of pressurised equipment.
