Wärtsilä to supply new Bio-LNG plant in Latvia

0

Finland-based technology group Wärtsilä will supply its biogas upgrading and liquefaction solutions to Latvian company AS Agrofirma Tervete (AT), a move that will enable AT to turn its agricultural waste into Bio-liquefied natural gas (LNG) at its site in Tervete, Latvia.

To upgrade the biogas the company will harness Wärtsilä’s Puregas CA50LBG technology, enabling the removal of carbon dioxide (CO2) and hydrogen sulphide (H2S) followed by its MR10 (mixed refrigerant) technology for the liquefaction stage. 

The upgrading process involves the Puregas solution separating CO2 from the biogas through chemical adsorption, turning raw biogas into biomethane, which can be liquefied to produce more than ten tonnes of Bio-LNG per day. 

Having carried out ‘extensive’ research prior to signing with Wärtsilä, Endijs Drebeiniks, AT, stated that energy efficiency, methane recovery rate, and the high content in the product gas were key deciding factors in its choice.
