Process Simulation for Atmospheric Vacuum Distillation Column of Crude Oil

Crude distillation unit is the first process of the petroleum process,and it＇s very important to the subsequence units and the whole refinery plant.Even the simulation technology has been the most important method of the process analysis,the veracity of the simulation is the bottleneck.For primary distillation tower,atmospheric distillation tower and vacuum distillation tower of steady-state process simulation,the final process simulation result was extremely similar to the actual process parameters by selecting appropriate mid-cycle set variables of distillation tower and vacuum distillation tower simulation methods.The result shows that the atmospheric vacuum distillation process simulation can accurately reflect the actual process state,and it can serve as an effective way to guide production and operation optimization.
