摘要：
The present disclosure relates to an apparatus for generating glycol and a method thereof. More particularly, the present disclosure relates to an apparatus for generating glycol including (a) an aldol reactor; (b) an extractor for extracting an aldol product, unsaturated aldehyde, using an organic solvent that is not mixed with water; (c) a distillation column for removing a raw material from a solution extract that is discharged from the extractor; (d) a hydrogenation reactor for hydrogenating a solution extract that is discharged from the distillation column; and (e) a divided-wall distillation column for isolating glycol from a hydrogenated solution product that is discharged from the hydrogenation reactor, wherein the hydrogenation reactor is a fixed-bed catalytic reactor that is filled with a copper-based catalyst, and a method of preparing the same.
In accordance with the present disclosure, an economical apparatus for preparing glycol which reduces loss of a raw material and provides a high glycol yield while inhibiting generation of by-products, and a method of preparing the same are provided.
