In this work steady state and dynamic behaviors of quaternary simple distillation columns by means of steady state
design cost and dynamic resiliency have been investigated. To quantify the dynamic performance, losses of products
due to disturbances have been considered in the objective function. In addition, operating costs such as utilities have
been included in the objective function. To separate a quaternary mixture into four products, twenty two configurations
have been used. It has been observed that disturbance frequency and amplitude affect dynamic behavior strongly. The
results indicate that there is no clear pattern for configuration rankings. It means that the best configuration depends on
feed composition, type and frequency of disturbance. Values of objective function and configuration rankings for a
given feed composition, products price, load frequency and amplitude are given.
