I have some questions regarding LNG receiving stations and would like to ask the experts for help.

Thread Content

First, when an LNG receiving station’s LNG storage tanks are put into use for the first time, where should the natural gas and nitrogen generated as a result of pre-cooling be discharged? If it is discharged into a flare, will the flame of the flare go out? (For ground flares) Can nitrogen be released without lighting the eternal flame in the torch? Will it affect the performance of the torch? Second, for the low-temperature submersible pump (centrifugal) in the storage tank, aside from the pump itself which is pre-cooled by immersion, how should the pump’s outlet lines, minimum return lines, etc. be pre-cooled? Third, the BOG compression and liquefaction category; the specific equipment includes: cryogenic tanks, BOG compressors, nitrogen compressors, and turbine expanders. (When systems such as water, gas, electricity, and seal gas are already in use,) is there a specific sequence in which these devices should be started up during the first operation? For this entire system, what is the cooling rate of the cryogenic tank? There are still other issues that require the help of experts; these are the things I can think of for now, and more will be added later. {:3_64:}
