Natural Gas Specific Heat Data Tables

Natural Gas Specific Heat Data Tables

Natural Gas Specific Heat Data Tables

(OP)
Hello All,

I am currently working on a tool and I am looking for the individual specific Molar Heat Capacity MCp (Ideal-Gas State), Btu/(lb mol • °R) for compounds normally found in Natural Gas including (C1-C10), Nitrogen, Hydrogen, Water, CO2, etc.

Most of the tables I have come across are only at specific pressures however the specific molar heat capacities change dependent on both temperature and pressure.

Does anyone know of good resources to get this data from that has this information with respect to varying changes in pressure and temperature?

RE: Natural Gas Specific Heat Data Tables

Standard reference for these props for many hydrocarbon compounds is the API Technical DataBook. For most props, mathematical expressions are included.
Else, work out these values manually for any P and T from tabulations for enthalpy - Perry Chem Engg Handbook has tables for superheated C1, C2, C2=, C3 and many others.

Thank you georgeverghese! Perry Chem Engg Handbook has some great tables. Wish there was a way to get them in a simple excel format!
I couldn't seem to find the API Technical Databook. Hopefully someone on this thread can add it for future references.

Hi,
Probably good to have a look at GPSA (Gas Processors Suppliers Association) handbook .
Good luck
Pierre

Hi pierreick,
Unfortunetky I checked there. They have an impressive list of gases however all information is based on standard temperature and pressure.

Pulsater555,
for models based on ideal gas laws the generic correlations of H vs. T (from which you can extract (dH/dT)P or cp) are ok,
for real fluids you should include departures (from ideal fluids) calculated with EOS or equivalent systems,
see the previous threads at Eng-tips forums.

Hi
What about ASPEN-HYSYS?
