Description
Summary:There is rapid growth in the usage and demand of crude oil in various industrial fields. Thus, the price of the petrol is rising due to the stronger-than-expected demand for petroleum products. With the available information, most of the modeling models used today is only steady state models. The procedure for this work was firstly forming a mathematical model for the theoretical stage of the column. Then based on the partial equation obtained, the relationship between input variable and output variable was studied. After that, Aspen Plus simulation of CDU was run in steady state mode and the results obtained was studied. Next, a dynamic simulation of CDU in Aspen Plus Dynamic was run and the dynamic behavior of CDU model was studied based on the results obtained. Based on the result obtained from steady state simulation, it was proven that the change of energy balance of the column lead to a change in the mass balance of the column. As the conclusion the dynamic simulation results shown on all the changes of process variable with respect to time until the system stability achieved. A good dynamic model is necessary to develop a proper control strategy. Thus, this work was very helpful in understanding dynamic behaviour of CDU and used to increase the efficiency of refining process which also increases the yield of the product.
