The technology group Wärtsilä will supply biogas liquefaction and biogas upgrading solutions in Tervete, Latvia. The order was placed by AS Agrofirma Tervete, that will utilise the plant to upgrade, polish, and liquefy biogas from agricultural waste into bioLNG.
Wärtsilä will provide its Puregas CA50LBG for removal of CO2 and H2S (hydrogen sulphide) followed by an MR10 (mixed refrigerant) technology for the liquefaction stage. The installation is designed for production of 10 tons bioLNG per day. The delivery also covers the supply of spare parts and service agreement.
Prior to making the contract decision, we carried out extensive research and comparisons of the biogas upgrading technologies currently available. The energy efficiency, methane recovery rate, and the high content in the product gas were the key factors in selecting Wärtsilä. Their ability to move as many high-quality molecules as possible, and as efficiently as possible, together with their capabilities to deliver a biogas upgrading and liquefaction plant under a single turnkey solution was very important to us.Endijs Drebeiniks, AS Agrofirma Tervete
