Modelling and simulation of 1,2-dichloroethane production by ethylene oxychlorination in fluidized-bed reactor

A comprehensive reactor modal for ethylene oxychlorination for the producti on of 1,2-dichloroethane in a fluidized-bed reactor is developed. The model is based on the two-phase theory of fluidization and allows for the change in volumetric gas flow rate in the dense phase due to the change in number of moles accompanying the reaction. The model predictions compared favorab ly with the industrial data obtained from the literature. The effect of dif ferent parameters on the behavior of the system is also investigated. It ha s been found that the bubble diameter, ethylene molar feed fraction, reside nce time, and height at minimum fluidization have significant effects on th e reactor performance.
