Detailed introduction

Gasification station

Gasification station

LNG has become the main gas source or transition gas source for cities that cannot use natural gas for gas supply, and is also a supplementary gas source or peak-regulating gas source for many cities that use natural gas for gas transmission. The LNG gasification station is a receiving, storage and distribution LNG satellite station, and is also an intermediate regulating place for towns or gas companies to transfer LNG from the manufacturer to the user. LNG gasification station has gradually built up in many small and medium-sized cities with developed economy and energy shortage in the southeast coast of China, relying on its short construction period and the ability to quickly meet the demand of gas market. It will become a transition before permanent gas supply facilities or natural gas pipelines. Gas supply facility.

Equipment requirements:

The process characteristics of the 1LNG station are “low temperature storage and normal temperature use”. The design temperature of the tank reaches minus 196 degrees Celsius (the boiling point of LNG at normal temperature is minus 162 degrees Celsius), while the temperature of the outbound natural gas is not lower than the ambient temperature by 10 degrees Celsius.

The cryogenic storage tanks and cryogenic liquid pumps of the 2 stations are better in thermal insulation performance, and the cold preservation performance of valves and fittings is better.

The equipment, pipelines, instruments, valves and fittings in the low temperature zone of the 3LNG station have good operating performance under low temperature conditions, and have good mechanical strength, sealing and corrosion resistance.

4 Because the low-temperature liquid pump startup process is based on the inverter continuously increasing the speed to increase the power and increase the flow rate and provide high output pressure, the cryogenic liquid pump requires higher frequency and higher power, usually in a few seconds to ten seconds. Can meet the requirements, and the cold insulation performance is better.

5 Gasification equipment is required to be resistant to earthquakes, typhoon and meet design requirements under normal climatic conditions to achieve maximum 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; gasifiers and low-temperature hydrocarbon pumps are not regulated in the country in the process of manufacture. To carry out relevant US industry standards, the location of welding, renovating, repairing or moving the pressure vessel on the pressure vessel body must be reported to the inspection unit of the pressure vessel.
