Abstract:
The present application relates to an apparatus and method for purifying cumene. The apparatus and method for purifying cumene according to the present application can reduce the amount of energy consumption which occurs during purification processes and can provide an apparatus and method capable of efficiently purifying cumene.

Claim (Index 8):
A method for purifying cumene, the method comprising:\n a light material removal process in which a stream from an alkylation reaction unit is introduced to a lights cut column to be removed of lights and water; a benzene separation process in which a stream from a transalkylation reaction unit and a stream discharged through a lower portion of the lights cut column are introduced to a benzene column to be separated into benzene and a cumene stream; a cumene separation process in which the cumene stream separated above is introduced to a cumene column to be separated into cumene and a polyisopropylbenzene stream; and a polyisopropylbenzene separation process in which the polyisopropylbenzene stream separated above is introduced to a polyisopropyl column to be separated into polyisopropylbenzene and heavy materials.
