摘要：
In the momentum of reducing CO2 emission of coal to ethylene glycol process, a novel carbon dioxide utilized coal to ethylene glycol (CUCtEG) process is proposed, simulated, and optimized. The novel process is assisted with coke oven gas to enhance resource and energy efficiencies as well as reduce CO2 emission by integrating with dry/steam-mixed methane reforming technologies. Based on the rigorous steady-state simulation of the process, key operational parameters of the novel process are investigated and optimized. The optimal feed ratio of coke oven gas to coal and the split ratio of that for steam methane reforming reaction are 0.68 and 0.74. Compared with the traditional process, the CO2 emission of the new process is reduced by 94.05%, and the exergy efficiency is increased by 15.17%. © All Right Reserved.
