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.

Claim (Index 14):
A method for producing linear alpha olefins, the method comprising:\n oligomerizing ethylene to produce linear alpha olefins, wherein the linear alpha olefins include hexene-1 and butene-1; introducing the linear alpha olefins into a distillation column, wherein an overhead stream is separated from a bottom stream, wherein the overhead stream comprises butene-1, hexene-1, and an impurity; and directing the overhead stream into a fractionation column, wherein the butene-1 and hexene-1, are separated to yield a butene-1 fraction and a hexene-1 fraction, wherein the hexene-1 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 hexene-1 fraction, at least a portion of the collected hexene-1 fraction is recycled to the distillation column.
