Abstract

See full text

The invention relates to a multi-strand plant and a corresponding process for producing olefins from oxygenates in which a plurality of reactor trains which each comprise one or more catalyst-containing oxygenate-to-olefin (OTO) reaction zones are arranged in parallel and operated in parallel, wherein at least one of the parallel reaction zones may be operated in a regeneration mode while the OTO synthesis reaction may be performed in the other reaction zones parallel thereto. The partial product streams obtained from the individual reactor trains operated in a synthesis mode are discharged via partial product conduits, combined into a complete product conduit using a connecting device, compressed using a compressor and separated into a plurality of olefin-containing hydrocarbon fractions using a multi-stage workup apparatus. The inventive configuration of the plant and of the process reduces pressure drops and thus enhances the yield for short-chain olefins, for example propylene.
