文摘

The reactor is optimized by applying differential evolution (DE) algorithm as an effective and robust optimization method. In case 1, inlet temperature of each segment has been optimized via differential evolution (DE). Same approach has been applied in the second case in order to achieve optimum water permeation rate. In the third case, the optimum profiles of temperature and water removal have been obtained. 1.5%, 55% and 70% enhancement in the dimethyl ether production have been obtained in case 1, case 2, case 3 respectively.
