Abstract: A process for preparing an olefin stream for oligomerization comprises fractionating an olefin stream to provide an ethylene stream and a olefin rich stream. Acetylenes in the ethylene stream are converted to ethylene in the presence of hydrogen to provide a concentrated ethylene stream that can be oligomerized.

Abstract: A process for preparing an olefin stream for oligomerization comprises fractionating an olefin stream to provide a light gas stream and a olefin rich stream. Oxygenates are absorbed from the olefin rich stream into a water wash stream to provide an oxygenate rich water wash stream and a washed olefin stream. Oxygenates are then adsorbed from the washed olefin rich stream, so the deoxygenated stream can then be oligomerized.

Abstract: A process for preparing an olefin stream for oligomerization comprises fractionating an olefin stream to provide a light gas stream and a olefin rich stream. The olefin rich stream is selectively hydrogenated to convert diolefins to mono-olefins and provide a mono-olefin stream and oligomerizing the mono-olefin stream over an oligomerization catalyst to provide an oligomerized stream.

Abstract: A process is provided for preparing a hydrocarbon stream for oligomerization. The process strips dimethyl ether from an olefin stream using a stripping column. Lighter olefins such as C3− olefins are also removed. The C4+ olefins can then be sent for further processing including selective hydrogenation followed by oligomerization.
