Abstract

The experience of application on system of chemical-engineering simulation in HYSYS of firm «Aspentech» for designing of air separation units has caused the necessity of more accurate calculation of phase equilibrium. The binary interaction coeffients for the PRSV equation of state were adjusted for the purpose of maintenance of the best concurrence of results of calculations with the experimental data and programs of the enterprise. The results of HYSYS introduction into helium and hydrogen liquefiers and refrigerators simulation and for calculations of multistage cryogenic units are presented.
