摘要
Provided is a device for regenerating mono-ethylene glycol (MEG) including a pre-treatment unit to receive a raw material and remove the low soluble salts therefrom, a distillation unit connected to the pre-treatment unit and configured to receive the raw material from which the low soluble salts are removed and generate a treatment solution by vaporizing the water, a flash drum connected to the distillation unit and configured to receive and vaporize at least a portion of the treatment solution, a high soluble salt removal unit connected to the flash drum and configured to remove the high soluble salts from the treatment solution, an extractor connected to the flash drum and configured to extract vaporized MEG, and a recovery unit connected to both the distillation unit and the extractor and configured to recover MEG, wherein the distillation unit includes a steam ejector into which vaporized water and external high-pressure steam flow.
