This chapter is dedicated to describing the numerical model of membrane permeation and the rigorous thermodynamic model of supersonic separators and their installation in HYSYS process simulator. It also recapitulates the determination of multiphase speed of sound from Chap.  5 for accurate calculation of Mach number within the supersonic separator. Two unit operation extensions (UOEs) were developed in Visual Basic programming language in integration with HYSYS simulator. MP-UOE uses an approximate method calibrated with operation data, whereas SS-UOE is entirely based on thermodynamics, dismissing calibration techniques. MP-UOE and SS-UOE use the thermodynamic infrastructure of HYSYS: property packages and several proved multiphase flash algorithms. Case studies are investigated for validation and certification of both unit operations. A literature review is also presented.
