A method of converting methanol feedstock to olefins includes contacting the feedstock to produce a first effluent comprising DME, unreacted methanol and water; cooling the effluent to separate DME as a first vapor and form a first stream comprising water, unreacted methanol, soluble DME and oxygenates; contacting the first vapor to produce a second effluent comprising olefins, unreacted DME, water and oxygenates; cooling the second effluent to separate the olefins and the unreacted DME as a second vapor and form a second aqueous stream comprising water, soluble DME and oxygenates; compressing the unreacted DME and the olefins; separating DME from the olefins to produce DME free olefins product and a third aqueous stream comprising the absorbing liquid, absorbed DME, soluble oxygenates and hydrocarbons; stripping the methanol, DME, soluble oxygenates and hydrocarbons as vapor and a fourth aqueous stream comprising clean water; and recycling at least a portion of the vapor.
