Processes for the production of ethylene glycol |
| abstract |
A process for the production of ethylene glycol comprising: n (i) supplying ethylene and oxygen and an organic chloride moderator to an EO reactor, thereby producing a reactor product stream; n (ii) supplying the reactor product stream to an EO absorber, thereby producing a fat absorbent stream; n (iii) supplying the fat absorbent stream to an EO stripper, thereby producing a concentrated ethylene oxide stream and a lean absorbent stream; n (iv) recirculating the lean absorbent stream to the EO absorber; and n (v) supplying the ethylene oxide stream and/or the ethylene carbonate stream to hydrolysis reactors with an alkali metal salt hydrolysis catalyst to form an ethylene glycol stream; n wherein the process additionally comprises: n (vi) removing a glycol bleed stream from the ethylene oxide stripper; and n (vii) adding a base to the ethylene oxide stripper such that the pH in the bottom section of the stripper is maintained from 9.5 to 12.0. |
