ABSTRACT:
The present invention provides processes for removing CO2from an effluent stream derived from an oxygenate to olefins reaction system. In one embodiment, the invention comprises contacting the effluent stream with a first CO2removal medium in a first CO2removal zone under conditions effective to remove a first portion of the CO2from the effluent stream and form a first CO2depleted stream. The first CO2depleted stream is contacted with a second CO2removal medium in a second CO2removal zone under conditions effective to remove a second portion of the CO2from the first CO2depleted stream and form a second CO2depleted stream comprising less than about 0.5 vppm CO2.
