Generally, the LNG storage tank used by the gasification pressure regulating skid is a low temperature adiabatic pressure vessel designed with a double-layer structure. The inner tank is used to store LNG, and its outer wall is wrapped with multiple layers of thermal insulation material, which has good thermal insulation. The enclosure and support system are designed to withstand the forces associated with the movement of the transport vehicle. Commonly used LNG cylinders are 175L, 195L, 210L, 375L, 410L, and 495L. It is stipulated that the volume of a single gas cylinder 175L steel cylinder in the gasification station of the cylinder group should not be greater than 410L.
There are various storage forms of gasification pressure regulating skids, generally LNG storage tanks. The commonly used storage volumes range from small storage tanks (5~100 m3), medium storage tanks (100~1000 m3), and (1000~40 000 m3) ) large storage tanks and large storage tanks over 40,000 m3; in the LNG gasification station project, the more commonly used LNG storage tanks have two types of stack insulation and vacuum powder insulation, with volumes ranging from 30 m3, 100 m3, 150 m3, 700 m3 (combination) varies, and there are two types of structures: vertical and horizontal. There are also a small number of large-scale gasification stations that directly use large storage tanks as urban gas sources, or mobile types that use tank trucks as storage media.
