Abstract: A process for purifying linear a-olefins, comprises: providing an organic phase comprising a linear a-olefin; providing an alkaline aqueous phase I; providing an amine; mixing the linear a-olefin, alkaline aqueous phase I, and amine; separating the aqueous phase I from the organic phase; adding water to the organic phase thereby forming an aqueous phase II; bringing into contact the organic phase with carbon dioxide; separating the aqueous phase II which comprises a solid formed in the organic phase when contacted with carbon dioxide; wherein the purified linear a-olefins are obtained in the organic phase.

Abstract: A method for processing an oligomerization product stream includes discharging the oligomerization product stream from an oligomerization reactor through a product outlet line, and heating the oligomerization product stream, heating a wall of the product outlet line, or both. The oligomerization product stream includes solvent, linear alpha olefins, a polymer byproduct, or a combination of at least one of the foregoing. The heating is to a temperature that is greater than the melting temperature of the polymer byproduct present in the oligomerization product stream.
