  • Methods for toluene recovery from linear alpha olefin production
    Patent number: 10781147
    Abstract: The present disclosure provides a method of flushing a reactor used in the production of linear alpha olefins, including flushing reactor equipment with toluene from a solvent source, wherein the reactor contains by-products from the production of the linear alpha olefins, wherein the by-products include a polymeric material. The flushed toluene containing polymeric material is directed into a separation train containing the linear alpha olefins, wherein the polymeric material is soluble in at least one of the linear alpha olefins. The linear alpha olefins can be separated from the toluene and the toluene is recycled to the solvent source.

  • FRACTIONAL DISTILLATION SYSTEMS AND METHODS FOR LINEAR ALPHA OLEFIN PRODUCTION
    Publication number: 20190010099
    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.
