Coke oven gas dry refined unit and hydrogen production unit of pressure swing adsorption are widely used in the metallurgical enterprise in recent years. The desorp-tion gas from the two units in running accounts for about 15% and 60% of their raw material gas amount, respectively. The desorption gas has an important use value. The utilization of the gas from the two units in the old area of Masteel is introduced. The problems in running and the relevant measures are described.% 近年来焦炉煤气干法精制及变压吸附制氢装置在冶金企业得到了广泛应用，两装置运行过程中产生的解吸气分别占其原料气量的15%和60%左右，具有重要的利用价值。介绍了马钢老区焦炉煤气精制和制氢装置解吸气利用情况和运行中出现的问题以及应对方法。
