摘　　要：为解决焦炉煤气制备甲醇工艺实施过程中氢气利用率低、原料单一的问题,在对焦炉煤气制备甲醇工艺现阶段存在问题进行综合分析的基础上提出了补碳的改造目标和原则;确定了补碳方式,并重点对纯二氧化碳和闪蒸气两种补碳技术和工艺以及最终的效果进行综合评估,最终确定采用闪蒸气的补碳方式为最佳。In order to solve the problems of low hydrogen utilization rate and single raw material in the implementation process of coke oven gas to methanol production,based on a comprehensive analysis of the current problems in the coke oven gas to methanol production process,the goals and principles of carbon supplementation transformation are proposed.The carbon supplementation method has been determined,and a comprehensive evaluation has been conducted on the two carbon supplementation technologies and processes of pure carbon dioxide and flash steam,as well as their final effects.Finally,it has been determined that the best carbon supplementation method is to use flash steam.
