Comparative Study and Analysis of Cryogenic Storage Tanks with Different Storage Energy Media

Abstract Liquefied natural gas (LNG), ethylene, ethane, propane, and other clean energy are often stored in a cryogenically frozen state on large scale. As the core equipment of cryogenic storage tanks, if different media stored, there certain differences design tanks. Although specifications differ little, is lack systematic research. This paper compares material, process, structure, construction, commissioning tanks such as LNG studies feasibility replacing C2 C3 refrigerated hydrocarbon with The results show that have common points terms construction standards, processes, outer cold insulation materials, while internal tank medium density, temperature, aspects lead to technology, start-up, commissioning. It concluded theoretically feasible replace tank, not suitable due high temperature inner material.
