LNG storage tank
LNG is transported from the LNG liquefaction plant to the LPG gasification station in the gas-using city through the tank truck storage tank, and the tank truck storage tank is boosted by the unloading supercharger, so that a certain pressure difference is formed between the tank truck and the LNG storage tank. This pressure difference unloads the LNG from the tank car into the storage tank. At the end of unloading, the gas-phase natural gas of the tanker is recovered through the gas-phase pipeline of the unloading platform. The LNG in the storage tank is pressurized by the gasification reflux pressurization process of the storage tank booster, so that the LNG in the storage tank flows to the downstream pipeline, passes through the air-temperature vaporizer for heat exchange and gasification, and then After pressure regulation, metering, odorization and other processes, it enters the user pipe network.
