Application Of iCON~? Software In Solving Vapor-Liquid Equilibrium Problems

摘要

Solving vapor-liquid equilibrium (VLE) in thermodynamic problems through manual calculation takes a long time to be completed because it requires iterative solution and involves too many formulas. In petrochemical industry and chemical industry, fast and accurate calculations are very important to ensure operation is running smoothly. iCON~? simulation software, developed by PETRONAS Sdn Bhd., can be used to solve VLE problems. As such, its level of accuracy in solving vapor-liquid equilibrium problem needs to be explored. The main objective of this research is to provide guidelines on how to solve VLE problems using iCON~? software, drawing phase diagram of Pxy and Txy and compare experimental data with results generated from iCON~? and another design simulator of HYSYS~? software. The results from both softwares showed that the obtained phase diagrams are very close to the experimental data.
