Abstract
In the refining process, Distillation columns are frequently used in chemical plants to separate one or several feed mixtures of two or more components. This study addresses the optimal operation in C2 stripper column. In reality, however, the feeds may vary in their flow rates, temperature, or compositions, which results in the process operating at non-optimal values. Therefore, we use Aspen HYSYS simulation software to builds up the plant model and get simulated data. In addition, using Aspen HYSYS simulation software presents the situation of the de-ethanizer. However, the challenges of developing the soft sensor are: (1) the compositions of the process input are highly dependent on the types of crude oil, which is varied from the front process. (2) the time delay of inspecting the ethane composition is around 1-2 hours. Therefore, the proposed approach for solving these challengers is using the PLS with moving window adaptive model.
