This application discloses an integrated method and system for the co-production of MTO methanol and refined methanol, belonging to the field of chemical technology. The co-production method provided by this application includes: feeding crude methanol into a light-duty removal distillation column for pre-distillation treatment to obtain a pre-distillation column bottom component; dividing the pre-distillation column bottom component into two streams, one as the output of MTO methanol and the other as a reprocessed component of the pre-distillation column bottom; feeding the reprocessed component of the pre-distillation column bottom into a refined methanol distillation column for distillation treatment to obtain a distillation column top component and a distillation column bottom component; at least a portion of the distillation column top component is output as refined methanol, and the distillation column bottom component is returned to the light-duty removal distillation column. This application achieves the co-production of refined methanol using only two columns, eliminating the need for additional independent equipment, significantly reducing equipment investment costs, and enabling flexible adjustment of both MTO methanol and refined methanol products, thus possessing broad application prospects in the industrial-grade MTO methanol field.
