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.

A process for processing an olefin stream comprising:
- fractionating an olefin stream to provide an ethylene stream and an olefin rich stream;
- converting acetylenes in said ethylene stream to ethylene in the presence of hydrogen to provide a concentrated ethylene stream;
- and
- oligomerizing said concentrated ethylene stream.

A process for processing an olefin stream comprising:
- fractionating an olefin stream to provide an ethylene stream and an olefin rich stream;
- converting acetylenes in said ethylene stream to ethylene in the presence of hydrogen to provide a concentrated ethylene stream;
- absorbing oxygenates from said olefin rich stream into a water wash stream to provide an oxygenate rich water wash stream and a washed olefin rich stream;
- and
- oligomerizing said concentrated ethylene stream and said washed olefin rich stream.
