محاكاة وحدة فصل الهواء بطريقة التبريد العميق باستخدام برنامج Aspen Hysys

Abstract

Oxygen gas is one of the products of the process of deep cryogenic air separation and has many uses in medical and industrial field, and the process of separation of air by withdrawal of large amount of air, which is compressed, cooled and liquefied during the process of air distillation. In this study is simulation of the air separation unit to produce 160 m3/hr of oxygen gas at pressure of 10 bar using Aspen Hysys program. A Sensitivity Analysis test was performed for the air separation unit and found the increase in pressure to increase the production rate and increase the unit performance and increase in the reflux ratio increases the purity of the product. The use of simulation software and its application to the air separation unit contributes to research and development of the air separation unit.
