A boiloff reliquefier for a large LNG storage plant has been operating successfully since the beginning of 1970 in Ambergate, Engl. A flow chart for the liquefaction plant is presented. The plant has a unique control system which gives an efficient and economical operation range from 100% down to 30% of design capacity. The plant runs fully automatically. The LNG facility consists of the following elements: (1) LNG storage tank of 5,000-ton capacity; (2) the offloading facilities for road tankers carrying 15 tons of LNG; (3) the export system; and (4) the reliquefaction system. The tank is filled from road tankers which deliver the LNG from the Canvey Is. terminal to the Ambergate site. The required refrigeration for the liquefaction plant is generated in a closed helium cycle, which consists of compressors, counterflow heat exchanger, boiloff-gas condensers, and expansion turbines.
