| titleOfInvention | Process for preparing ethylene glycol |
| abstract | The present invention provides a process for preparing a reactor product stream by (i) feeding ethylene and oxygen and an organic chloride modifier to an ethylene oxide reactor, where the ethylene and oxygen are reacted in the presence of a catalyst to produce ethylene oxide; (ii) feeding the reactor product stream to an ethylene oxide absorber, wherein ethylene oxide is recovered from the reactor product stream by absorption in water in the absorber zone to produce a fat absorbent stream; (iii) feeding a fat absorbent stream to an ethylene oxide stripper, wherein the fat absorbent stream is vapor stripped to produce a concentrated ethylene oxide stream and a lean absorbent stream; (iv) recycling the lean absorbent stream to an ethylene oxide absorber; (v) optionally feeding a concentrated ethylene oxide stream to one or more carboxylation reactors, wherein the ethylene oxide is reacted with carbon dioxide to form an ethylene carbonate stream; And (vi) feeding the concentrated ethylene oxide stream and / or the ethylene carbonate stream to at least one hydrolysis reactor, wherein the ethylene oxide and / or ethylene carbonate is selected from at least one basic alkali metal salt Reacting with water in the presence of a cracking catalyst to form an ethylene glycol stream, and (vii) further removing the glycol bleed stream from the ethylene oxide stripper; And (viii) adding a base to the ethylene oxide stripper so that the pH of the bottom portion of the stripper is maintained in the range of 9.5 to 12.0 or less. |
