Enthalpy of Methane??
Enthalpy of Methane??
(OP)
Hi all,
I am trying to calculate the temperature I need to raise methane so that it doesn't begin to freeze once its pressure has been droped through a regulator via the Joule Thompson affect. I know the following conditions - upstream pressure, downstream pressure, downstream temperature to prevent freezing, say about 3 deg. C or so.
It is my understanding that the enthalpy of methane remains the same during the J-T affect.
Therefore my question is, where can I find values of enthalpy for methane for a given pressure & temperature so I can find the temperature the methane needs to be at before its pressure is reduced.
Many thanks

Well, what are the upstream and downstream conditions, since the J-T coefficient varies with T and P?
