| titleOfInvention | A kind of low power consuming by preparing dimethyl ether from methanol method |
| abstract | The present invention is a kind of low power consuming of chemical field by the method for preparing dimethyl ether from methanol, and this method process flow includes: that the methanol from tank field is 1. carried out two-stage preheating through gaseous effluent cooler, methanol preheater；2. raw material preheating methanol enters reactor after vaporization tower vaporizes, the reaction gas after reaction is divided to two strands, one goes methanol preheater, one removes the one of reboiler of vaporization tower；3. two strands of reaction gas are utilized after a part of heat into converging before methanol second level preheater, then with after heat exchange of methanol from rectifier bottoms gas-phase feed；4. the top of the distillation column dimethyl ether enters dimethyl ether return tank, a part reflux after evaporative condenser is cooling, a part is produced as product.Compared with prior art, the present invention can rationally make full use of the heat generated in entire production system, save a large amount of process cooling waters, and process route is more optimized, while can also reduce equipment investment, be suitble to large industrialized. |
