1. The process characteristic of LNG gasification skid is "low temperature storage, normal temperature use". The design temperature of the storage tank reaches minus 196 degrees Celsius (the boiling point of LNG at room temperature is minus 162 degrees Celsius), and the temperature of the outbound natural gas is required to be no lower than 10 degrees Celsius of the ambient temperature.
2. The low-temperature storage tanks and low-temperature liquid pumps of the station have better thermal insulation performance, and the cooling performance of valves and pipe fittings is better.
3. The equipment, pipelines, instruments, valves and their accessories in the low temperature area of the LNG gasification skid have better operating performance under low temperature conditions, and have good mechanical strength, sealing and corrosion resistance.
4. Since the start-up process of the cryogenic liquid pump relies on the frequency converter to continuously increase the speed to increase the power, increase the flow rate and provide high output pressure, the cryogenic liquid pump requires faster frequency increase and power expansion, usually within a few seconds to ten seconds. It can meet the requirements, and the cold and heat insulation performance is better.
5. The LNG gasification skid is required to be able to resist earthquakes and typhoons under ordinary climatic conditions, and meet the standard of gasification flow.
6. The manufacture and daily operation management of cryogenic storage tanks and filters have been incorporated into the national specifications for the manufacture, acceptance and inspection of pressure vessels; LNG gasification skids and cryogenic hydrocarbon pumps are not regulated by relevant laws and regulations in my country. During the process, the relevant industry standards of the United States are implemented, and the position of welding, modification, maintenance or moving of the pressure vessel on the pressure vessel body shall be reported to the inspection unit of the pressure vessel.
