Abstract
The operating conditions for a heat-integrated ethylene quench column are optimized and diagnosed for controllability and resiliency. Since a bank of seawater coolers largely meets the column’s cooling duty requirements, the heat-exchanger by-pass flow fractions were optimized as a function of seawater temperature, using a specially adapted genetic algorithm. The controllability and resiliency of the quench column are studied and two alternative MIMO control configurations are investigated. Of particular interest was the impact of the nominal operating position of the bypass on disturbance rejection capacity.
