Software for calculating the density of gases at different temperatures and pressures?
Thread Content
Dear marine friends, I searched the forum for half a day without finding anything, so I’m reaching out to ask if anyone has software for calculating the density of single gases at different temperatures and pressures Thank you :)
Using the gas equation pV=nRT, where p is pressure, V is volume, n is the number of moles, R is a constant, and T is absolute temperature. Here, n = M/Mmol, where M is mass and Mmol is molar mass. Therefore, pV = MRT/Mmol. Since density ρ = M/V, we have ρ = pMmol/RT. Thus, the density of a gas can be calculated as long as the pressure, molar mass, and absolute temperature are known. There is no software for this; rather, an algorithm exists.
Thank you; this is the ideal gas law, and it cannot be used at high pressures and high temperatures
If it’s not possible, can we just use HYSYS?

The ideal equation is not applicable at high pressures and high temperatures
