The process dynamics can be understood by various testing procedures. Thus the solutions of the process problem can be brought out and verified a with the simulation program . With case studies, the Dehydration tower of a DMT plant is well understood . The main problem o f this tower is flooding of acid on the t op or dilution of acid in the bottom. This study shows that the bottom temperature control can keep the acid concentration within range . Further improvement can be achieved by a feedforward control for the change of the teed stream . Energy is saved if the reboiler-reflux decoupling control loop is added .
