Hi Breizh;
Thank you for your comment and suggestions. You time is highly appreciable indeed.
There will be a lot of factors coming into play. Based on filed operations what I have seen that there should not a drop of 10 c per hour, so calculation supposed to based on dT= 1 hr. But unable to set up the calculations.
After, I suppose to find, how much liquid LNG I suppose to pump into tank to extract the heat because liquid LNG will first absorb the heat and evaporate to gas without change in temp means latent heat of vaporization then further this evaporated vapor will further absorb hear and reach certain temp.
I do have this process in mind which works logically at field. The calculation which you were referring through search engine on this forum might not the same which I am trying to set up.
Your further suggestions are most welcome.
