Abstract

A general purpose digital simulator that can be used for studying either the transient response or control behavior of multicomponent tray distillation columns has been developed. The DYCONDIST simulator, written in FORTRAN 77, utilizes a column model that solves the coupled nonlinear material and energy balance equations for each stage. Control performance of any column is analyzed by the user deciding upon a control strategy and then invoking one or more or the existing control algorithms or employing a user-written control algorithm. Features of the simulator are described and its use is illustrated for studying the open loop (dynamic) behavior and control behavior of a 29 tray depropanizer.
