| titleOfInvention | For the production of the method for ethylene glycol |
| abstract | The invention provides the method for the production of ethylene glycol, said method comprising the steps of: ethene, oxygen and organic chloride negative catalyst are supplied to ethylene oxide reactor by (i), wherein ethene and oxygen react generation oxyethane in the presence of a catalyst, produce reactor product stream thus; (ii) described reactor product stream is supplied to ethylene oxide absorber, wherein by absorbing with water in described resorber section, collecting ring oxidative ethane from described reactor product stream, produces rich absorption stream thus; (iii) described richness is absorbed stream and be supplied to oxyethane stripper, wherein stream is absorbed to described richness and carry out steam stripped, produce concentrated ethylene oxide streams and poor absorption stream thus; (iv) described poor absorption stream is circulated in described ethylene oxide absorber again; V described concentrated ethylene oxide streams is optionally supplied to one or more carboxylation reaction device, its ethylene oxide and carbon dioxide reaction by (), form ethylene carbonate ester stream; (vi) described concentrated ethylene oxide streams and/or described ethylene carbonate ester stream are supplied to one or more hydrolysis reactor, wherein under the existence of hydrolyst being selected from one or more alkaline alkali metal salt, oxyethane and/or ethylene carbonate ester and water react, and form glycol flow; Wherein said method comprises following other step: (vii) removes ethylene glycol overflow stream from described oxyethane stripper; (viii) alkali is joined in described oxyethane stripper, make the pH of stripper bottom section remain at least 9.5 at the most 12.0 scope. |
