It is well known that the capacity of crude distillation units in any refinery reflect the capacity of refinery itself, and that is why because we consider that these units the first stage and all other units such as vacuum distillation, hydrotreating, reforming, catalytic cracking, and others depend on them. So we devoted our effort to keep these units work with high performance and efficiency.
The purpose of this work is to develop crude distillation units in Daura oil refinery, rise their performance level and detect were the weak points are concentrated to overcome.
Our work here conducted by simulation program (HYSYS) and consists of two stages, the stage before changing operating conditions and the stage after changing operating conditions and we will discuss each one separately later.
From this work we found that these old units contain many mistakes due to long time of operation since the year 1954 and these mistakes are concentrated in miss operation due to absence of daily close monitoring to the operation conditions and product specifications as to gap and overlap conditions and it was really effect badly on rectification efficiency
