Are the insulation pipelines at LNG receiving stations in continuous circulation, or are they only used in advance during unloading?
The receiving station has not been contacted; what aspects are you considering? I work in LNG plants, and we focus on energy consumption and BOG. In fact, the energy consumption is relatively low; the main issue is the amount of BOG that needs to be flashed. We also asked the design firm which method would be better, but we didn’t get a clear answer, so we carried out our own calculations.
It should be in a state of continuous low-flow circulation; otherwise, the LNG in the insulation pipelines will absorb heat and vaporize, generating large amounts of BOG, which can even affect the unloading of LNG.
