what is the lng vacuum storage tank in the gasification station?
generally, lng vacuum storage tank shall be set in cofferdam, and the single tank volume of lng vacuum storage tank is generally 30m ³ or 60m ³， lng storage tank is the key storage container of lng gasification station and an indispensable part of lng gasification station. as an employee in lng manufacturing industry, do you really know it? let's know it in detail:
the tank inner container is made of high-quality austenitic stainless steel 06cr19ni10 plate or imported 304 plate; the outer container is made of high-quality carbon steel q345r steel plate. common insulation methods of lng vacuum storage tank include high vacuum multi-layer winding insulation and pearlescent sand powder insulation.
the safety protection measures system consists of tank accessories, including: pressure gauge, liquid level gauge, one for use and one for standby at the root, fully complete closed safety valve, overflow port, bursting disc
there are two measures for lng vacuum storage tank: liquid inlet at the upper end and liquid inlet at the bottom end. the liquid inlet at the upper end can use the cold liquid to liquefy the bog gas in the storage tank. both measures can be taken. this shall be selected according to the actual situation in the liquid unloading process. therefore, lng vacuum storage tank is an indispensable part of gasification station.
