WebConventionally, dimethyl ether (DME) was synthesized from methanol and purified using two distillation columns, which contributes about 50-70% to the cost of production. Using reactive distillation process, the conversion of methanol can be enhanced greatly and purifying the DME at the same time, thus reducing the cost of production, significantly.
