Abstract: A method of separating linear alpha olefins includes: passing a feed stream comprising linear alpha olefins through a first column; distributing a C8− fraction to a top portion of the first column; distributing a C9+ fraction to a bottom portion of the first column; passing the C8− 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.
