The Centre for Process Systems Engineering has a large activity in molecular systems engineering that ranges from fundamental developments in thermodynamics modelling to the use of advanced thermodynamics in process and product design.

As part of this effort, we are developing a CAPE-OPEN compliant thermophysical property package based on the SAFT equation of state. This will make a sophisticated implementation of SAFT technology directly available within standard process modelling tools such as ASPEN PLUS and gPROMS.

The SAFT equation of state is distinguished by its ability to model reliably complex fluids such as polymers, surfactants or refrigerants. Our current implementation is based on the SAFT-VR version of SAFT, and incorporates efficient and robust numerical techniques for the evaluation of a range of thermodynamic properties.
