摘要
为进一步解决焦炉煤气转化甲醇原生产工艺甲醇产量低以及驰放气直接排放造成的能源浪费和环节污染的问题,在对原焦炉煤气转化甲醇模型验证的基础上,提出了采用膜分离技术分离驰放气、氢气、二氧化碳并采用补碳操作改善氢碳比的优化思路,并对其中关键参数进行了优选。经仿真评估,优化的焦炉煤气转化甲醇的工艺流程可提升甲醇的产量4.7万t,并有效提升了氢气的利用率,实现了二氧化碳的零排放。
In order to further solve the problems of low methanol production and energy waste and environmental pollution caused by direct discharge of purge gas in the original production process of methanol conversion from coke oven gas,based on the validation of the original coke oven gas to methanol model,an optimization idea was proposed to use membrane separation technology to separate purge gas,hydrogen gas,and carbon dioxide,and to improve the hydrogen carbon ratio through carbon replenishment operation.The key parameters were optimized.After simulation evaluation,the optimized process of converting coke oven gas to methanol can increase the production of methanol by 47000 tons and effectively improve the utilization rate of hydrogen,achieving zero carbon dioxide emissions.
