摘要： A process for separating a target glycol from a mixture of the target glycol and one or more C2-C8 diols by distillation, involves providing a feed mixture comprising the target glycol and a C2-C8 diol. A water feed stream is directed to a bottom of a first distillation column operating at a temperature greater than or equal to 180°C to separate a first overhead stream comprising a first portion of the target glycol and a first bottoms stream comprising the C2-C8 diol. In a second distillation column, a second overhead stream comprising a second portion of the target glycol is separated from a second bottoms stream comprising the C2-C8 diol. The feed mixture is directed to one of the first distillation column and the second distillation column. The first overhead stream is passed to a reboiler of the second distillation column to transfer heat from the first overhead stream to a portion of the second bottoms stream recycled to the second distillation column.
