Abstract: A system for, and method of, recovering salt from a rich mono ethylene glycol MEG stream includes a flash separator having a desanding hydrocyclone located in the hot MEG recycle loop of the flash separator; a first solids fluidization device located at the bottom end of the flash separator's brine column; a second desanding hydrocyclone arranged to receive a salt slurry stream created by the first solids fluidization device; and an accumulator located downstream of the second desanding hydrocyclone and having a second solids fluidization device located at its bottom end. Each solids fluidization device includes means for causing the motive fluid to exit the device in a swirling motion to fluidize the salt components contained in the resident fluid. The overflow from the second desanding hydrocyclone is the motive fluid for the brine column and a produced water, condensate water, or seawater stream is the motive fluid for the accumulator.
