摘要

为减少传统煤制乙二醇过程资源利用效率低和CO

排放量高等问题，提出了一种集成CO

高效利用的煤制乙二醇过程，并对其进行了全流程建模及系统分析。与传统过程不同，新过程利用焦炉气来提高其资源利用率和能量效率，集成甲烷干重整与湿重整技术降低CO

排放。在全流程建模的基础之上，对新工艺的关键操作参数进行了分析与优化。结果表明，焦炉气的最佳进料比和甲烷蒸汽重整反应的分配比为0.68和0.74。与传统过程相比，新工艺的CO

排放降低了94.05％，同时㶲效率提高了15.17％。

Abstract

In the momentum of reducing CO

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 CO

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 react

ion are 0.68 and 0.74. Compared with the traditional process

the CO

emission of the new process is reduced by 94.05%

and the exergy efficiency is increased by 15.17%.
