Modeling and Adaptive Control Simulation for a Distillation Column

Abstract

This paper presents mathematical modeling and adaptive control simulation for a distillation column based on the energy balance configuration. In this distillation modeling, the reflux rate L and the boil up rate V are used as the inputs to control the purity of the distillate overhead and the impurity of the bottom products. The mathematical modeling and simulation is accomplished over three stages: Nonlinear system, Linearization, and Reduced order system. The adaptive control is used with linear model reference controller (LMRC). Results from the simulation are helpful for initial steps of a petroleum project feasibility study and design.
