ARTICLE TITLE : Modelling and simulation of an oxychlorination reactor in a fluidized bed


ABSTRACT: Taking 1,2-dichloroethane from the oxychlorination reaction is a commercially very important process due to the large application of the 1,2-dichloroethane in the chemical industry of PVC production. This work presents the modeling and simulation of an oxychlorination reactor with a fluidized bed. The pseudo-homogeneous model with one-dimensional flow in steady state was applied based on the theory of fluidized bed in two phases. It allows the sensitivity analysis of the operational and project parameters of the reactor. The ordinary differential equations system that represents the mathematical model of the reactor was solved through the application of the numerical method of Newton-Raphson's. The results obtained have proved that the developed model represents the system suitably, in spite of the one-dimensional model. The effect of different parameters was investigated through the sensitivity analysis, and the results show that the parameters that have the largest influence on the reactor performances are: fluidized bed height, bubble diameter, residence time, cupric chloride weight in the catalyst, and emulsion phase temperature.
