Abstract: A process for flushing an oligomerization reactor is described, including flushing the oligomerization reactor with a flushing medium comprising C6 linear alpha olefins, C8 linear alpha olefins, C10 linear alpha olefins, or a combination including at least one of the foregoing, to provide a purge stream comprising the C6 linear alpha olefins, C8 linear alpha olefins, C10 linear alpha olefins, or a combination including at least one of the foregoing, and a polymer byproduct of an oligomerization reaction. A process for the oligomerization of an olefin is also described, wherein the process includes oligomerizing the olefin in the reactor to form a reaction product stream comprising linear alpha olefins, and subsequently flushing the oligomerization reactor according to the process disclosed herein.

Abstract: A method of column control includes: passing a feed stream and a make-up stream through a column; withdrawing an overhead fraction from the column; purging at least a portion of the overhead fraction; cooling at least a portion of the overhead fraction in a heat exchanger and passing it through a reflux drum; withdrawing a purge stream and a distillate stream from the reflux drum, wherein the distillate stream has a constant flow rate; recycling at least a portion of the distillate stream back to the column; and passing at least a portion of the distillate stream to a downstream process.
