Method for separating glycol product produced by catalytic hydration

The invention relates to a method for separating a glycol product produced by catalytic hydration, which solves the problems that in prior art, glycol concentration in a reaction solution during a direct hydration process is low, due to employed multiple-effect evaporation to remove water, the process flow is long, the equipment is more, the energy consumption is high and the production cost is high. The method comprises the following steps: a glycol aqueous solution with 20-40% of percentage concentration by weight from an auto catalytic hydration unit is introduced in the central part of an evaporator, after being separated, the glycol aqueous solution with 60-70% of percentage concentration by weight can be obtained at the bottom of a tower, and the steam material flow can be obtained at the top of the tower. The technical scheme of the invention better solves the problems, and the method of the invention can be used in an industrial production for producing glycol by ethylene oxide catalytic hydration.
