description The disclosure provides a method of purifying a linear alpha olefin product that includes feeding a linear alpha olefin feed stream comprising the linear alpha olefin product and ethylene into a feed stage of a distillation column, the distillation column having a plurality of stacked stages positioned between an overhead outlet and a bottoms reboiler including a stripping section and a rectifying section; feeding an aliphatic paraffin hydrocarbon solvent to the rectifying section of the distillation column to absorb linear alpha olefin; adding heat to at least one of said plurality of stacked stages in the stripping section of the distillation column between the feed stage and the bottoms reboiler; withdrawing an overhead stream comprising ethylene from the overhead outlet; and withdrawing a bottoms stream from the distillation column comprising the linear alpha olefin product.
