Abstract: A method for recovery of a product fraction from a mixture comprising an impurity and linear alpha olefins, the method comprising: introducing the mixture into a distillation column, wherein an overhead stream is separated from a bottom stream, wherein the overhead stream comprises a Cn product, a Cn+x product, and an impurity, wherein n is an integer from 4 to 30, wherein x is an integer from 0 to 26; directing the overhead stream into a fractionation column; and separating a Cn product fraction and a Cn+x product fraction in the fractionation column, wherein the Cn+x product fraction comprises at least a portion of the impurity, wherein, when an amount of the impurity is greater than 1 part per million in the Cn+x product fraction, at least a portion of the collected Cn+x product fraction is recycled to the distillation column.

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.

Abstract: A method for removal of an organic amine from a hydrocarbon stream includes mixing the hydrocarbon stream including the amine with an aqueous inorganic acid in a volumetric ratio of hydrocarbon stream: aqueous inorganic acid of greater than 1.5:1 to 5:1, phase separating a hydrocarbon phase and an aqueous phase, removing the hydrocarbon phase, mixing the aqueous phase with an aqueous alkaline solution, phase separating the aqueous phase and an organic phase, and removing the organic phase. The aqueous inorganic acid has a concentration of greater than or equal to 30 weight percent. The disclosed method results in improved phase separation time during an amine removal process.
