Abstract

Processes and an apparatus for reducing heavy oxygenate recycle for an MTO reaction zone. After separating product and water from the MTO reaction effluent, an oxygenate rich stream is passed to a conversion zone in which methanol in the oxygenate rich stream is converted into DME. A DME rich stream is separated from heavy oxygenates and is recycled back to the MTO reaction zone. The conversion zone may include a reactive distillation column, or the conversion zone may include a reactor vessel and a separate separation vessel.
