%X This study has been constructed using Aspen HYSYS ver.12.1 and regression analysis had been performed by MICROSOFT EXCEL 2010 to obtain a new correlations to predict the product yields from delayed coker unit with a wide applicable range of operating variables which is more reliable with refineries data and a simulation molding of delayed coker unit has been accomplished to maximize the gas oil yield for a refinery data by optimization of process variables.The resulted correlations from performed regression analysis which is applicable in the following operating range Furnace outlet temperature 480 – 520 C°, Recycle ratio wt% 3-20 and Coke drum pressure 100-500 KPa.Gas Oil wt% = 0.131472 T – 0.08547 R – 0.00048 P – 7.79018Coke wt% = 0.034775 R – 0.18382 T + 0.000142 P + 114.5429Gases + Naphtha wt% = 0.050695 R + 0.05235 T + 0.000339 P – 6.75269Where R=Recycle Ratio wt%, T=Furnace Outlet Temperature °C, P=Coke Drum Pressure KPaThe findings from optimization by linear programming performed by MICROSFT OFFICE EXCEL 2010 indicated that gas oil yield could be increased by 4 wt% instead of coke byproduct by lowering the recycle ratio to 5% wt from fresh feed and increasing the heater outlet temperature to 510°C.Also the results showed that the change in coke drum pressure has a minimal effect in product yield. The outcome from the modified process conditions studied and a profit estimated at approximately 40 million dollar yearly.
