Abstract

Methods and systems for fractionating a crude alpha methylstyrene (AMS) feed using one or more dividing wall columns are provided. The method can include introducing a crude AMS to a fractionation column wherein the fractionation column contains a dividing wall disposed at least partially within the fractionation column such that an internal volume of the fractionation column is divided into at least a pre fractionation section and a main fractionation section. The crude AMS can be introduced to the pre fractionation section of the fractionation column. A light hydrocarbon can be withdrawn from the fractionation column at or proximal a first end thereof a side stream can be withdrawn from the main fractionation section of the fractionation column and a heavy hydrocarbon can be withdrawn from the fractionation column at or proximal the second end thereof.
