  • Patent number: 11052325
    Abstract: Provided are a mono-ethylene glycol (MEG) recovery apparatus and a MEG recovery method. The MEG recovery apparatus includes a pretreater receiving the raw material from a raw material supplier to remove the low soluble salts, a first distiller connected to the pretreater to receive the raw material from which the low soluble salts are removed, and to form a first treated solution by vaporizing a certain amount of the water, a high soluble salt remover connected to the first distiller to remove the high soluble salts from the first treated solution, a second distiller connected to the high soluble salt remover to form a second treated solution by vaporizing the water from the first treated solution from which the high soluble salts are removed, and a recovery unit connected to the second distiller to recover the second treated solution.

  • Patent number: 10822294
    Abstract: 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.
