    • The present invention relates to a system and a method for producing dimethylether and methanol. The system for producing dimethylether and methanol comprises: a separation stability injection part which is arranged in order to separate natural gas supplied from a gas field according to the number of carbons; a modification part which is connected to the separation stability injection part and is arranged so that the natural gas supplied from the separation stability injection part is turned into synthetic gas; a dimethylether methanol formation part which is connected to the modification part and is arranged so that dimethylether and methanol are produced from the synthetic gas supplied from the modification part; a dimethylether methanol purification part which is connected to the dimethylether methanol formation part and is arranged so that dimethylether and methanol are purified from gas supplied from the dimethylether methanol formation part; and a fuel supply and synthetic gas reuse part which is branched off from a path connected to the dimethylether methanol purification part form the dimethylether methanol formation part, and is connected to the modification part so that unreacted synthetic gas passing through the dimethylether methanol formation part before entering the dimethylether methanol purification part is supplied to the modification part. Therefore, operational costs required to dimethylether and methanol production processes can be reduced, and the energy efficiency of the dimethylether and methanol production process can be improved.
