wet gas compression

wet gas compression

wet gas compression

(OP)
does the polytropic stage method PSPF() in Prode Properties allow to simulate wet gas compression with high values of liquid fractions ?
I have a two phase application, according the manual it should allow to simulate a polytropic stage with phase equilibria but the limits of application (for this method) are not given.

RE: wet gas compression

chemlite,
my version of Prode Properties includes two models for polytropic stages

1) Huntington (for gas phase)
2) Proprietary (Prode) method applicable to both gas and vapor + liquid phases

as far as I know the proprietary (Prode) method is applicable to both gas and vapor + liquid and there are not limits for liquid fraction,
you can solve both gas compression (but Huntigton runs faster) and vapor + liquid,
I have not tested pumps but it should work for pumps, too.
For additional information you may contact the developer (there are additional methods for pumps/compressors available as extended models)

RE: wet gas compression

(OP)
Hans,
thanks for the information,
my version (Base) has two models,
it seems that software does a test to detect liquid phase,
in case of liquid Huntington method stops (generating error) while Prode method solves in any case,
I undestand that (for Prode method) there are no limits for liquid fraction.
