Improving Rectification Technology in Daura Refinery Crude Distillation Units by HYSYS

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