Abstract

The model of distillation column process is a model of multivariable, inter-channel effects and strong nonlinearities. The paper introduces the dependence between the input flows, reflux flows and top and bottom products based on the distillation column kinematics and the mathematical equations at steady state. This study uses an adaptive neural fuzzy inference system (ANFIS) and an Extended Kalman filter to estimate the component in a 2-component distillation column, applying Matlab-Simulink to simulate, thereby comparing and evaluating these estimation solutions.
