摘要:
A process and a plant for producing an olefin stream from a hydrocarbon mixture feed stream, wherein the olefin stream is depleted as regards its content of oxygen-containing organic compounds (oxygenates) as compared to the feed stream. The hydrocarbon mixture feed stream is charged to a separation column operated by a thermal separation process, for example to a distillation column, wherein a material stream enriched in oxygenates is withdrawn via a side outlet and removed from the process. The process according to the invention is particularly useful for processing the product streams obtained in the olefin synthesis by an OTO process.
