A method of separating linear alpha olefins includes: passing a feed stream comprising linear alpha olefins through a first column; distributing a C8&#x2212; fraction to a top portion of the first column; distributing a C9+ fraction to a bottom portion of the first column; passing the C8&#x2212; fraction directly to a top portion of a second column; passing the C9+ fraction directly to a bottom portion of a second column; distributing a C11+ fraction to the bottom portion of the second column; withdrawing a C10 fraction as a side draw from the second column; and passing a liquid stream and a vapor stream from the second column to the first column.

Method of separating linear alpha olefins

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.
