Abstract
The binary distillation column is one of the most important operating units in chemical engineering. Wood & Berry binary distillation columns separate feed streams (F, XF) into top products (D, XD) and bottom products (B, XB). The control design in the binary distillation column has several constraints caused by non-linearity of the process, multivariable interactions, and presence of a disturbance. Based on that constraints, it needs a modern control method that can make the system response to track the set point change and reduce or eliminate the disturbances, so the product composition output as desired. Adaptive Internal Model Control 2 Degree of Freedom (AIMC 2 DoF) method is one of the modern control methods that are capable of controlling multivariable plants and reduce or eliminate existing disturbances. Based on all the tests performed, the AIMC 2 DoF controller using Skogestad filter parameter tuning method has the smallest IAE value compared to the other methods.
