[Terrapreta] Pressure at 180 C

[Eric Robinson]

Greetings,

I would also warn against using the Ideal Gas Law, since we are not 
dealing with ideal gases.  However I would only use saturated steam 
tables for systems consisting of only saturated steam.  For a system of 
(presumably) species similar to syn-gas and light hydrocarbons, I would 
start off by using the Peng-Robinson equation of state, or perhaps 
UNIFAC.   

(Note that as a U of A student I have an inherent bias toward 
Peng-Robinson).
