So I got another problem that I could use some advice on. It has come time to create a datasheet on a conventional inlet scrubber for use in a typically sweet and dry compressor station (Horizontal with cyclone tubes) and I have to input conditions (density viscosity) for the liquids even though...
Ok I have never been asked this question before so I need some help.
Currently I have 8 aerial coolers in a first in last out configuration (also called "U" configuration I believe) and people i.e my boss is concerned that the first cooler will have more flow due to its smaller pressure drop...
I am curious as to why the values for enthalpy in HYSYS (Peng-Robinson with Lee Kesler Enthalpy Correction EOS) are negitive for typical natural gas. Does this mean that HYSYS compares the enthalpy to a refernce value because when I look up the enthalpy value in the API databook the value is...
In HYSYS using Peng-Robinson EOS the mass enthalpy values are all negative, does this mean that HYSYS is comparing the enthalpy at you T and P to that of some refernce state? or is it the enthalpy of formation?
I was wondering if any one has experince in designing pipeline equipment for dense phase natural gas. Our gas is 18 MPa and -2 C. I am curious to see the effects this phase has had on their equipment ( pressure drops, psv sizings and such)

I have been trying to create a spreadsheet to come up with residual properties via Lee-Kesler EOS I have however hit a snag. In Lee-Keslers paper he describes a term Vr=Pc*V/Tc*R where V is the volume of a simple fluid. The paper I am refering to is called "A Generalized thermodynamic...
In Lee-Kesler paper "A generalized thermodynamic coorelation based on a three-parameter corresponding state" he makes refernce to a Vr = Pc*V/RTc where V is the volume of a simple fluid. what is this simple fluid?
I can't seem to find the appropiate calculations for PSV relief flowrate calculations for natural gas in the dense phase. Am I just missing something? or does anyone know of some resources that may be of help
I am curently designing a orifice plate that is attached to the discharge of a pressurized vessel. Since this is a transient system I am not sure at what point during the depressurization I should use for the designing of the orifice. Any advice would be appreciated.
