A new type of gas distributor for dividing wall column is proposed.A three-dimensional model is established by using computational fluid dynamics (CFD) and the double Eulerian homogeneous multiphase flow model is used to simulate this gas distributor.At the same time,the experimental process of this distributor is set up.The effect of this distributor on the gas distribution on both sides of the partition is compared with the experimental data to verify the established CFD model.The results show that the simulation results of the model are in good agreement with the experimental results.This new type of gas distributor for dividing wall column can adjust the gaseous phase flow on both sides of the partition.
