Patent number: 11524927Abstract: 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. In some embodiments it is expected that the temperature of the process may range from above 165° C. to about 250° C. and/or that the pressure may be atmospheric.Type: GrantFiled: July 16, 2015Date of Patent: December 13, 2022Assignee: CAMERON INTERNATIONAL CORPORATIONInventors: Christopher Stephen King, Brian Edward Messenger, Harihara V.

Patent number: 10918966Abstract: A system and method to vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is vaporized, any solids present in the process stream come out of the process stream and move into the heating medium. These solids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or used in the pump around loop's heater in case of mechanical vapor recovery.Type: GrantFiled: May 16, 2019Date of Patent: February 16, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Z.
