The LNG vaporization station is a place for receiving and vaporizing LNG. It is used to receive LNG from LNG terminal stations, gas liquefaction stations, or transported by liquefaction unit cars, tank cars or railway tank cars. After gasification, metering and odorization, It is supplied to gas users through the urban pipe network system.

　　Process flow of LNG vaporization station. The LNG transported by the tanker is turned on at the unloading platform of the gasification station to pressurize the tanker with its own booster. The pressure difference between the LNG tanker and the storage tank in the station is formed, which plays a role in the pressure difference. Next, the LNG is fed into the low-temperature storage tank of the gasification station for storage through the unloading hose. The low-temperature storage tank in the station makes the pressure of the storage tank reach the value through the storage tank booster, and the LNG in the tank enters the LNG vaporizer through the liquid outlet pipe.

　　The equipment used for LNG vaporization output in the cryogenic storage tank of the LNG vaporization station is an air-bath vaporizer. If the pressure in the LNG storage tank is relatively low, the storage tank booster should be opened to pressurize the storage tank when entering the air-bath vaporizer for gasification. LNG enters the air-bath vaporizer under the action of the pressure difference between the two. As the temperature changes, LNG undergoes a phase change and becomes a gaseous gas, which is then regulated, metered, and odorized by an outbound pressure regulator, and then sent to the city gas pipeline system.

　　If the outlet gas temperature of the air-bath vaporizer does not meet the delivery requirements, the water-bath vaporizer connected in parallel with the air-bath vaporizer should be turned on to heat the low-temperature gas until the outlet air temperature meets the delivery requirements. The station pressure regulator regulates pressure, measures and adds odor, and then sends it to the city gas pipe network system for users to use.

　　The LNG vaporization station is equipped with a BOG buffer tank, which is used to store the boil-off gas generated by the LNG tanker and storage tank due to heat leakage, as well as buffer the boil-off gas from the LNG tanker and storage tank, and can also be used to stabilize the outlet gas pressure. The boil-off gas in the LNG tanker and storage tank passes through the gas-phase pipeline on the top of the tank body, is heated by the BOG heater, and then enters the BOG buffer tank. When the pressure in the BOG storage tank reaches the value, the gas in the storage tank is also input to the city gas pipe network user.
