摘 要：正In general,either above-ground tanks or in-ground tanks been used worldwide to store *** types of tanks have a number of problems such as the need for a large site for storage tanks,ground settlement,high operating costs,an excessive boil-off ratio due to radiant heat from the sun,and so *** attempts have therefore been made in the past to store LNG underground in unlined containment,though without success. The new system for storing LNG in rock caverns had been developed and verified through the design,construction and operation of a LNG pilot plant in Daejeon,***
