pressure vs temperature
(OP)
I need to know the change in temperature in(deg. c ) which will happen if the pressure of the natural gas is reduced from 1200 psi down to 80 psi using a step down regulator .

RE: pressure vs temperature
I can give you approximate metric figures. Pressure reduction of every 2 bar cools down the gas roughly 1 deg.C.
Maybe you find exact data searching for Joule Thomson effect.
RE: pressure vs temperature
Caution, this estimation is only for dry gases. If you start condensing liquids, it can be significantly out. But, for natural gas, that is not likely going to be the case though you might get some small amounts of condensation of the heavies.
