Hi Folks,
I have to heat up (from 20 °C to 600°C) a mix of Methane and Hydrogen under a pressure of 200 bar. I need the hydrogen´s thermophisical properties under those conditions. Does someone know some internet site or handbook where I can retrieve these properties?

THX

Perry, Chemical Engineering Manual. I have the sixth edition. It has table 3-248b with properties (specific volume, enthalpy and entropy) up to 1000 K and 1000 bar.

http://webbook.nist.gov/chemistry  
shows more thermophysical properties, but goes up to 126.9^oC and 1210 bar

Does the Perry contain also the coefficient of thermal conductivity and the cinematic viscosity (or dynamic viscosity and density)?

Thanks for the undeserved star.
The answer on Perry is regretfully no.
J.P. Holman's Heat Transfer (McGraw-Hill) Table A-6, shows these properties at atmospheric pressure up to 900 K.

Please note the expected changes due to pressure are small.

From the NIST site I got that at 125^oC the "additions" when going from 1 bar to 200 bar are: for specific heat, 1.5%; for absolute viscosity 3.4%, and for thermal conductivity, 5.4%. Which tells us that the Pr number practically doesn't change with pressure.

Sorry, that's all I could gather on hydrogen from my sources.

I found this book:
R.D. McCarty, J. Hord, H.M. Roder (1981)

http://www.boulder.nist.gov/div838/Hydrogen/Publications/Publicationsmain.htm

It´s almost exaustive, there are almost all the hydrogen´s properties. :)

Thx again

The link that 25362 provided gives you all you need.

Cheers,
Joerd
