Abstract:
The objective of this study is to define the optimum ratio of Rawat to Nile Blend feed stream to Elobied refinery.Rawat crude hasrecently been discovered in Sudan, but has a high pour point and wax content, that’s why we blend it with Nile blend to overcome these short comings.The project studies the advantage ofblending Rawat crude with the main crude that is fed to Elobiedrefinery (NileBlend crude) by using different ratios to obtain a blend that can be distilled in distillation column of Elobied refinery.This has been done by using Aspen HYSYS simulator.
It is simulated by entering Nile Blend and Rawat Crude with different ratios (40/60), (50/50) and (70/30). The results showed thatas the ratio of Rawat crude to Nile Blend is increased in the feed crude, the percentage of residue in the bottom of thedistillation column increases.
The key words: Rawat, blending, Nile Blend,distillation,simulation, Aspen HYSYS.
