Abstract: A novel methyl acetate production with blast furnace gas-based CO and coal-based dimethyl ether is proposed to improve economic and environmental performances compared to conventional pathways. [Display omitted] • Design and simulation for methyl acetate process using blast furnace gas-based CO. • Comparing three methyl acetate production pathways originated from coal. • Identifying economic and life cycle environmental opportunities of proposed route. • Highlighting the role of CO recovery rate in improving benefit. The synthesis of methyl acetate from CO derived from blast furnace gas together with dimethyl ether offers the potential superiority both of benefit improvement and pollutions reduction. However, a quantitative analysis of this process is lacking. This work conducts a comprehensive evaluation of methyl acetate production with blast furnace gas-based CO and coal-based dimethyl ether (CVTMA) through process simulation, techno-economic analysis and life cycle assessment, and highlights its benefit compared to two conventional methyl acetate production pathways: the CCTMA with both CO and dimethyl ether from coal, and the CETMA with acetic acid and methanol esterification. The results show that the CVTMA route exhibits a reduction of 9.24 %–19.46 %, 11.73 %–23.67 %, and 10.40 %–21.43 % in the total production cost, total capital investment and minimum selling price compared to the CCTMA and CETMA pathways. Additionally, the CVTMA exhibits the most stable rate to address coal price fluctuations. For environmental performances, the CVTMA reduces life cycle primary fossil energy depletion by 6.32 %–11.06 % and water consumption by 18.03 %–41.43 % compared to the other pathways when the functional unit is 1 t of methyl acetate. The GHG emissions of the CVTMA case demonstrate 10.36 %–12.67 % reductions relative to other cases when the functional unit is defined as 1 t methyl acetate and 353 kWh electricity. Finally, a sensitivity analysis discloses that economic and environmental benefits increase with the raise of CO recovery rate. This work provides valuable insights for the high-value utilization of blast furnace gas and the cleaner development of methyl acetate production. [ABSTRACT FROM AUTHOR]
