Title: MEG RECOVERY APPARATUS AND MEG RECOVERY METHOD
Abstract:
The present invention relates to an MEG recovery apparatus and an MEG recovery method. An MEG recovery apparatus according to an embodiment of the present invention is an apparatus (100) for recovering mono-ethylene glycol (MEG) from a raw material (1) including water, MEG, a high solubility salt, and a low solubility salt, wherein the apparatus comprises: a pre-treatment unit (110) for receiving the raw material (1) from a raw material supply unit and removing the low solubility salt; a first distillation unit (120), connected to the pre-treatment unit (110), for receiving a low solubility salt-removed raw material (S) and vaporizing a predetermined amount of the water to generate a first treated solution (S1); a high solubility salt removing unit (130), connected to the first distillation unit (120), for removing the high solubility salt from the first treated solution (S1); a second distillation unit (140), connected to the high solubility salt removing unit (130), for vaporizing water from the high solubility salt-removed first treated solution (S1) to generate a second treated solution (S2); and a recovery unit (150), connected to the second distillation unit (140), for recovering the second treated solution (S2).
