摘　　要：为合理利用焦炉煤气,通过对比分析焦炉煤气转化为天然气和焦炉煤气转化合成甲醇的优缺点,探索了焦炉煤气综合利用的新方法。将焦炉煤气中的甲烷提取出来直接作为产品销售,剩余气体作为合成气用于合成甲醇。新工艺能源利用效率与常规制甲醇相比提高了25%左右;与常规焦炉煤气制天然气和焦炉煤气制甲醇相比,年利润分别提高5 187万元和1 117万元。To utilize the coke-oven gas reasonably,the advantages and disadvantages of the conversion of coke-oven gas into natural gas and methanol are analyzed in this study. The new technologies of comprehensive utilization of cokeoven gas are developed. The methane converted from coke-oven gas can be used as product directly. The residue gas is used to synthesize methanol. Compared with the conventional method, the energy utilization efficiency in methanol production with new technique is improved by about 25%. And the annual profits of natural gas production and methanol production from coke-oven gas are imoroved by 51.87 million and 11.17 million yuan.
