摘要
针对泰州石化公司甲乙酮装置尾气的组成特点,采用前冷却、吸附流程回收其中的氢气。通过冷却脱除尾气中夹带的液体和部分高碳醇;采用三塔吸附操作,在常温下脱除尾气中甲乙酮、仲丁醇及C4组分,高温下使吸附剂再生。装置标定结果表明,氢气的体积分数达到99.99%,回收率高达93.75%。
According to the composition of tail gas in methyl ethyl ketone device, hydrogen was recovered by cooling process before absorption recovery. Liquid and part of higher alcohols v/ere removed from tail - gas in cooling system, methyl ethyl ketone, see - butyl alcohol and C4 components were removed with three absorption towers at room temperature, while adsorbent was regenerated at high temperature. The volume fraction and recovery rate of product hydrogen reached 99. 99% and 93.75%, respectively.
