By optimizing and analyzing parameters of the columns for synthesizing dimethyl carbonate (DMC) by using Aspen Plus software, the optimum operation parameters were obtained. On this basis, the thermodynamic efficiency and CO2 emission of the synthesis process were compared and analyzed when aniline and ethylene glycol were respectively used as extraction agent. The results show that, compared with ethylene glycol as the extraction agent, using aniline as the extraction agent can lead to higher thermodynamic efficiency of DMC process, meanwhile the energy consumption and CO2 emission reduce significantly.
