LNG Processes

Abstract

Since 1964 the production capacity of LNG has grown at the rate of 20 percent per year worldwide. The large number of projects currently under consideration forecasts significant growth in the future. LNG production from a unit train has more than doubled since 1972 resulting in a reduction in the installed cost of a unit train of approximately 30 percent. The efficiency of the liquefaction process is now 35% greater than in 1972. The propane precooled-mixed refrigerant liquefaction process has been used in essentially all of the LNG projects since 1972. LNG process and equipment components will be improved incrementally in all areas in the future. Extensive application of modular construction techniques will reduce the time and cost of construction in remote areas of the world.
