March 5 (LNGJ) - Hamworthy Oil & Gas Systems, the developer and supplier of gas handling and liquefaction technology and now a unit of Finland's Wartsila, has secured its first contract for a biogas liquefaction plant from Norwegian company Cambi AS, a specialist in biowaste treatment. The biogas plant will treat 50,000 tons of food waste a year and produce around 14,000 Nm3/day of biomethane. The liquefaction plant is to be delivered early 2013 and Hamworthy's responsibilities will include feed gas compression, biogas cleaning and liquefaction and liquid biogas storage and export. Hamworthy's liquefaction plant design is based on conventional components and uses a plate-fin heat exchanger for the liquefaction process. The technology is scalable upwards to a capacity of at least 60 tons a day. The produced biomethane will be used as biofuel for buses in Oslo.
