Abstract

This study aims to examine the steady-state modeling of the current performance of the atmospheric distillation column at the Al-Diwiniya refinery, which can process up to 10,000 barrels per day of crude oil. The results of the steady-state simulations run by the Aspen Hysys V14 software were compared to the actual operating parameters of the refinery. These conditions included plant experimental ASTM D86 curves for various products, the flowrate of the refined products, and the temperature of the product trays. The simulation results showed a good agreement with laboratory ASTM D86 curves for all products except heavy Naphtha, which revealed a noticeable difference. The results of the flow rate of Light Naphtha, Heavy Naphtha, Kerosene and Gasoil showed good agreement except Off gas (Relative Error%= 25) and Atmospheric residue (Relative Error%=-0.6). Finally, the simulated temperature of draw trays for refinery products shows good agreement with the refinery data where Relative Error -8.3% for Off gas was the largest variance between the refinery and simulation results.
