Abstract
The present invention relates to a process for the removal of oxygenates from a gaseous stream also comprising carbon dioxide, said process comprising: a) providing a first gaseous stream comprising one or more mono-olefin(s), at least 100 ppm (by weight) of one or more oxygenates and at least 0.1 wt % carbon dioxide, and b) treating the first gaseous stream to produce a second gaseous stream comprising one or more mono-olefin(s) and at least 01 wt % carbon dioxide with reduced oxygenate content, wherein said treating comprises contacting the first gaseous stream with a first aqueous stream and with a first liquid hydrocarbon stream, and c) subsequently treating the second gaseous stream to remove the carbon dioxide therein.

A process for the removal of oxygenates from a gaseous stream also comprising carbon dioxide, said process comprising:
- a) providing a first gaseous stream comprising one or more mono-olefin(s), at least 100 ppm (by weight) of one or more oxygenates and at least 0.1 wt % carbon dioxide, and
- b) treating the first gaseous stream to produce a second gaseous stream comprising one or more mono-olefin(s) and at least 0.1 wt % carbon dioxide with reduced oxygenate content, wherein said treating comprises contacting the first gaseous stream with a first aqueous stream and with a first liquid hydrocarbon stream, and
- c) subsequently treating the second gaseous stream to remove the carbon dioxide therein, the majority of the carbon dioxide in the first gaseous stream being removed in step (c).
