Abstract

A method for processing an oligomerization product stream includes discharging the oligomerization product stream from an oligomerization reactor through a product outlet line, and heating the oligomerization product stream, heating a wall of the product outlet line, or both. The oligomerization product stream includes solvent, linear alpha olefins, a polymer byproduct, or a combination of at least one of the foregoing. The heating is to a temperature that is greater than the melting temperature of the polymer byproduct present in the oligomerization product stream.
