Virtually any physprops package
gPROMS® family products are used across virtually all process industry sectors, from cement manufacture to pharmaceuticals to food.
There is no universal physical properties package that can supply all requirements. For this reason PSE’s approach is to provide a wide range of optional rigorous physical property packages that cater for different needs.
gPROMS Multiflash properties
Infochem Multiflash, supplied by KBC Advanced Technologies, is the standard gPROMS physical properties package.
Multiflash is a highly rigorous properties package that supports all commonly-used thermodynamic and transport properties, including a wide range of equation of state and activity coefficient thermodynamic models.
Multiflash is specifically designed for equation-orientated modelling, providing tight convergence of internal iterations and analytical partial derivatives with respect to temperature, pressure and composition.
PSE can supply Multiflash with the DIPPR database supplied by the AIChE, providing component data for thousands of components.
OLI electrolyte properties
PSE provides OLI Systems’ OLI® electrolyte properties package for aqueous electrolytic systems.
Electrolyte chemistry is particularly complex and challenging to understand and predict, especially for real industrial systems containing many components and operating over broad ranges of temperature, pressure and concentration.
PSE’s efficient implementation of the OLI Engine makes it easy to access these properties from gPROMS ModelBuilder® and other gPROMS family products.
CAPE-OPEN physical properties
PSE has strongly supported the CAPE-OPEN initiative and its successor CO-LaN since inception.
gPROMS provides a CAPE-OPEN physical properties socket into which any CAPE-OPEN compliant physical properties package can be plugged – for example Aspentech’s Aspen Properties®, PROSIM’s SIMULIS® Thermodynamics, Aspentech’s COMThermo® and many others.
gSAFT: the future of advanced thermodynamics
Statistical Associating Fluid Theory, or SAFT, is an advanced molecular thermodynamic method that can predict a wide variety of thermodynamic properties of mixtures accurately based on physically-realistic models of molecules and their interactions with other molecules.
PSE has implemented the SAFT-VR and the SAFT-γ Mie group contribution methods developed at Imperial College London in the gSAFT® product. gSAFT is currently being supplied to lead customers by special arrangement.
Proprietary physical property packages
gPROMS provides a general open interface for interfacing of external property and thermodynamic tools.
Virtually any physical properties package can be interfaced to gPROMS with a few days’ effort.
