Abstract

Deodorizer column is one of the most important units of operation in the palm oil refining process. The column itself consists of tray column at bottom half and packed column at top half. To get an optimum composition of the bottom product and FFA recovery, a good controlling system needs to be installed. The proposed controlling system is a PID controller where the manipulated variables are the rate of sparging steam and the rate of cold FFA. This research is done through simulation with Aspen®, while the physical and chemical properties data are taken from Bailey’s book on vegetable oil. This research aims to find the steady-state simulation for the process. Next, we observe the dynamic response based on feed temperature, feed composition, and feed flow rate. Two different tuning methods are introduced. That is the Ziegler-Nichols setting and an IMC-based PID setting. A step-change in set point and load were introduced and the dynamic performance was evaluated using IAE calculation. The result showed that the best controller for the tray column is IMC based PID controller with Rivera 1 tuning, while for the packed column the best tuning is Ziegler-Nichols method.
