In methanol to propylene (MTP) process, there is small amount of dimethyl ether in output flow. Dimethyl ether should be removed in top of depropanizer column. A novel method is presented to remove dimethyl ether. This method is proposed based on the industrial data. A steady state model was develop and solved using MATLAB. At the end the optimization of the process was performed. MESH equations were implemented for the sake of modeling. Three key components are dimethyl ether, propylene, and iso buthylene. It is concluded that tary # for side flow and reflux ratio have important effect on the reduction of dimethyl ether.
