Short Contact, Elevated Temperature Meg Reclamation
11 Mar 20
Monoethylene glycol (MEG) may be reclaimed by a process that includes contacting a MEG-water-salt stream with a heat transfer fluid and then flash separating the MEG and water in the flash separator vessel where the pressure is higher than 0.3 barA (0.03 MPa), the temperature is in the range of above 120° C. to about 250° C., and the residence time of the MEG and water ranges from about 1 second to about 10 minutes, and then removing the MEG and water in an overhead of the flash separator vessel and removing the salt from the flash separator vessel.
