Liquid nitrogen to gas

[chunia]

Hi,

How to calculate how many BTUs it takes to convert one gallon of liquid nitrogen (LN2) into gas?
We use heat exchanger with 280F hot water. Output gas temperature 70F

TIA

Quark,

Thank you for spending your time to explain all details of the process to me. I do not want spend any more of everybody’s time on the issue.

The answer is : To convert one gallon of liquid nitrogen to the gas at 70F and 100 psi takes 1235.5 Btus

Again, thanks to everybody who helped me to find answer to the question.

Best regards
