Characteristics of LNG gasification station

The LNG is transported by the tank truck to the gasification station. The LNG unloading supercharger is used to increase the pressure inside the tank truck, and the LNG in the tank truck is sent to the LNG low temperature storage tank for storage. When discharging from the LNG storage tank, first increase the pressure of the storage tank through the self-pressurizing system of the storage tank, then open the liquid storage outlet valve of the storage tank, and send the LNG in the storage tank to the gasifier through the pressure difference. It is sent to the municipal gas pipeline network through processes such as pressure regulation, metering and odor removal. When the outdoor ambient temperature is low and the natural gas temperature at the outlet of the air-temperature gasifier is lower than 5 °C, a water bath heater is connected in series at the outlet of the air-temperature gasifier to heat the gasified natural gas.

Jianshen company can provide a gasifier suitable for liquid oxygen liquid nitrogen argon liquefied natural gas. Today we talk about the characteristics of LNG gasification station:
The process characteristics of the LNG gasification station are “low temperature storage and normal temperature use”. The tank design temperature is at least -196 ° C (LNG storage temperature is about -162 ° C), while the outbound natural gas temperature is required to be no less than about 10 ° C ambient temperature.

LNG gasification station cryogenic storage tanks, valves, pipelines and fittings have better cold retention performance. The equipment, pipelines, instruments, valves and fittings in the low temperature zone of the gasification station have good operating performance under low temperature conditions, and have good mechanical strength, sealing and corrosion resistance.

Gasification equipment is required to meet design requirements under normal climatic conditions to achieve maximum gasification flow. Cryogenic storage tanks, gasifiers, pipelines, and filters are all pressure vessels, so their management must be managed as pressure vessels. If the location of the pressure vessel is welded, modified, repaired or moved on the pressure vessel body, it must be reported to the inspection unit of the pressure vessel.
