Abstract:
Increasing of industrial society's need to refinery's product, high consuming energy in distillation process and pollution product in it cause to researchers investigate about the alternative process for crude oil refinery. At this time, supercritical fluid extraction was regard as a less energy consuming process. The aim of this work was prepare to a computerized model for simulating of crude oil refinery's process. In this work effects of temperature and pressure on the supercritical extraction were investigated. The experiment was done at four temperatures (35, 40, 45, 50°C) and four pressures (100, 120, 140, 160 bar) by supercritical carbon dioxide and obtained samples were analyzed by gas chromatography. Computerized model was prepared and its parameters were adjusted by experimental data and also the accuracy of model was determined by two experiments.
