CH4 P-H diagrama

(OP)
I am outsourcing and need a P-H diagram for CH4, could any one tell me where I can find it? thanks

GPSA Manual

RE: CH4 P-H diagrama

The GPSA manual has the best one I know of.  Perry's and perhaps the ASHRAE handbooks might have them but they are typically a lot smaller and harder to read values off of.

You might also check with any compressor vendors.  I would suspect they have mollier diagrams for methane available.

RE: CH4 P-H diagrama

CDMB:

The most authoritative and recognized source for complete Methane Thermodynamic data is no other than our USA government:

http://webbook.nist.gov/chemistry/fluid/

--and it is FREE, since our tax dollars have paid for it.  It gives you excellent, detailed, and down-loadable tabular data that drops right into Excel.  Granted, it's not in the form of an impressive (& inaccurate) Mollier diagram, but it detailed, thorough, and as recognized as anything you can obtain to back-up official and legal engineering calculations.  I think more than one forum member has found this out already.  The NIST gives complete, free information on 34 compounds in their database.  This should certainly fill your engineering need - if Methane (rather than Natural Gas) properties will do.

Montemayor,

I couldn't find it at the above link.

Many thanks!

Best regards,

Tom:

I just clicked on the Hyperlink and I was taken directly to the NIST website where you will find the first drop-down box for information called:

"1. Please select the species of interest:"

You drop the menu down and select "Methane".  Presto! You now have to fill in the information about Methane that you would like!

I don't know what the problem is with your attempt, but it should work - just like mine did when I clicked on the Hyperlink in my post.

I know it works and you're the first person to have trouble with my hyperlink and instructions.  Please try again; I guarantee it works!
