Report: Efficient liquid biomethane production with cryogenic upgrading

Producing liquid biomethane is an attractive way of valorizing biogas, provided that the gas treatment technology is adapted to a project’s capacity and cost-effective. By combining cryogenic upgrading with biomethane liquefaction, Cryo Pur developed a new integrated system, with a lower energy consumption and adapted to a wider range of biogas projects than previous solutions. This process has been successfully demonstrated in operation within the “BioGNVal” project since mid-2015. This article presents the process operation and its benefits.
