| titleOfInvention | A kind of polymethoxy dimethyl ether absorption, membrance separation combine dewatering |
| abstract | The invention discloses a kind of polymethoxy dimethyl ether absorption, membrance separation combines dewatering, comprises the following steps: sent into from the top of adsorption tower one by gas gas-phase objects stream unstripped gas, and carry out adsorption reaction in adsorption tower one；After molecular sieve in adsorption tower one completes absorption, entering regeneration stage, gas gas-phase objects stream unstripped gas carries out adsorption reaction in sending into adsorption tower two；During regeneration stage, under the effect of vacuum pump, stripping gas is discharged from the top of adsorption tower one, and after membrane separation, is incorporated into unstripped gas pipeline and enters the dehydration of next step adsorption deeply；After adsorption tower one completes regeneration, it is re-introduced into adsorbed state；After adsorption tower two completes absorption, enter regeneration stage.The present invention uses above-mentioned technique, on the basis of guaranteeing high product purity, more obtain high yield, make stripping gas again process without returning to leading portion rectification working process simultaneously, achieve the complete independent operating of dehydration workshop section, there is obvious technology and advantage economically. |
