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.<\div>
