standard gas condition
standard gas condition
(OP)
I have a sour gas mixture of 140mmscfd operating conditions are 75K and 1050psi.Does it means that at this condition the volume is 140mmscfd or at standard conditions. If in standard condition what is the temp and pressure. If I have to find the density of a particular gas say H2S what is the procedure.
I am egarly waiting for your response

RE: standard gas condition
The way you get density is to calculate it. The equation I use (which is by no means the only one) is
ρ= (P*SG)/(R(air)*T*Z)
Pressure and temperature are in absolute units. You didn't ask, but I'm sure you need to know that you cannot calculate a meaningfule velocity at an imaginary (i.e., standard) set of conditions, so:
qacutal=qstandard*ρstandard/ρactual

RE: standard gas condition
This leads to your second question. Yes, you do need to get the density of the gas at the flowing condition. In order to calculate the density you need to know the actual pressure, temperature and compressibility factor so that you can solve the gas equation PV = ZnRT.
As a first approximation you can take Z=1, but for good accuracy you should include Z as well. Finding Z is a whole new question. gogoogleit
