LNG tank, heat flux calculation and holding time verification in regards to insulation performance
LNG tank, heat flux calculation and holding time verification in regards to insulation performance
(OP)
Good day,
I'm having some troubles with the holding time calculation for a LNG tank. In the supplied xls file you have the calculation.
I got the max heat flow to the tank and the max daily evaporation losses. With that info i calculated that the first opening of the safety valve will be in 28 days (not sure about that calculation).
How would I calculate if this setup would hold for 60 days within the required parameters? For now, I presumed the heat flux through the insulation at 2W/m2 ?
If I left something out in the xls file please let me know.
Thank you very much for your help.
