knstar;
Please review your post above, think about what you are asking and re-phrase your question. I have absolutely no clue as to what you are asking.

I think he meant how can he maintain the content's temperature at -120F or whatever the low temp liquid NG is at.

One answer would be: lots of insulation. Do your heat transfer calculation and size the insulation thickness. This is your basic 2nd year engineering course material.

Be aware that you will have cold wall support clips design for your platforms/ladders and pipe supports. These design require insulating pads to isolate the attachements from the cold (this also lends to you maintaining the content temperature).

thanks for your all reply

i find that i describe not clearly

in my experience, i have no idea about how to keep the cold temperature (-126 F).

I try to search for the answer in the internet.

i find two, one is useing the some levels full vacuum to keep the cold temperature.

other one is useing the patent material to keep the cold temperature.

i think the two ways aren't suit for the tower which is so big(L: 42m ID: 2.2/1m)

so i come here to ask for advice.

thanks for your attention
