摘要	Coal to ethylene glycol (CTEG) technology can effectively alleviate the shortage of ethylene glycol, however, is criticized by severe greenhouse gas emissions. This study proposed four co-feed processes of coal and coke oven gas to ethylene glycol with different methane reforming technologies: steam reforming, dry reforming, combining steam and dry reforming, and tri-forming of methane technologies. The key operational parameters were investigated and optimized firstly in terms of the whole simulation models. A detailed technical, economic and environmental analysis of the novel co-feed processes was then conducted and compared with the conventional process. Results show that the optimal feed ratio of coke oven gas and coal of the co-feed processes is greatly different and changed from 34.20 kmol/t to 70.20 kmol/t. The carbon utilization and exergy efficiencies of the co-feed processes are increased by 16.90%-32.76% and 4.41%-10.28%. Their total capital investment and production cost are reduced by 8.92%-18.82% and 8.24%-19.43%, respectively. As a result, the internal rate of return of the co-feed processes is increased from 9.25% to 12.85%-18.85%. In addition, the co-feed processes can significantly reduce the direct CO2 emissions of the conventional CTEG process by 70.39%-95.28%. Thus, the cofeed processes have better technical, economic and environmental performance compared with conventional process. In particular, the CTEG process integrated with tri-reforming of methane technology has the best comprehensive performance in comparison with other novel processes.
