Help: Looking for Gas property software

AI Thread Summary
A user is seeking gas property software suitable for turbines and expanders, specifically for natural gas applications. The required software should handle inputs like inlet pressure, temperature, discharge pressure, mass flow, and process compositions, while providing outputs such as isentropic head and densities at various points. REFPROP from NIST is suggested as a viable option, although it primarily handles pure gases and requires programming for mixtures. However, it can calculate properties for natural gas mixtures as well. Engineering Equation Solver (EES) is also recommended, with a student version available online.

I'm looking for a gas property software which is used for turbine/expander. Below are the basic requirements for the tool:

Inputs:
Inlet pressure, inlet temperature, discharge pressure, mass flow, process components & compositions.

Outputs:
Isentropic head, density at inlet, density at outlet, liquid at inlet, liquid at outlet, Z, cp, cv…etc

Equation: SRK, Peng-Robinson, BWR, LK

Does anyone have any idea if there’s a tool which is good for nature gas applications?
Thanks

If you want gas property software, then REFPROP from NIST is a good database. It comes with a .dll you can use in Excel or VB (I think C++ too). It cost about $200 bucks. Version 8 includes a good library on hydrocarbons.

thanks, but I forgot to mention that I need mixture. NIST is for pure gas. It calculates each state points, still requires some programming.

No, it can do mixtures too. For example, I used it to find properties for Natural Gas based on a typical sample.

you can try engineering equation solver(EES). Its up there on net as a student version.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
