Abstract:
This project show a new opinion applied in Obeid Refinery which is addition of distillation unit contain distillation column, two heat exchanger and crude oil storage tank. this unit is added mainly to satisfy the demand of diesel in the near area as well as covered the shortage in the demand of the electrical sector. Design of this unit was carried out using ASPEN HYSYS as simulator, however the simulator was applied for the disgn of the distillation column with capacity 25000 bbl/day the methodology consider that the Nile blend is a complex mixture so the simulation results determent the light and heavy key between the products to calculate the minimum number of trays and the minimum reflux to determine the actual number of trays and the dimensions of the column in general. The main outcome of the design work is 41 trays and diameter of 1.5 m and 28.7m high.
