摘要
焦炉煤气作为焦化工业的典型富氢副产物,将其高效转化为氢气对钢铁行业低碳转型具有重要意义。针对焦炉煤气变压吸附(PSA)制氢系统因原料气组分波动、操作参数失当及吸附剂装填缺陷导致的性能下降问题,提出了提高原料气氢组分并控制流速、优化操作参数、明确装填标准、选用吸附剂等优化措施。上述措施实施后,氢气产量和氢回收率得到显著提高,单位电耗降低了11.68%,系统运行更加稳定高效。
Coke oven gas(COG),as a typical hydrogen-rich by-product of the coking industry,is significant for the low-carbon transformation of the steel industry when efficiently converted into hydrogen.Addressing the performance degradation of the pressure swing adsorption(PSA)hydrogen production system from coke oven gas caused by fluctuations in feed gas composition,improper operating parameters,and adsorbent packing defects,optimization measures were proposed.These included increasing the hydrogen content of the feed gas and controlling its flow rate,optimizing operating parameters,clarifying packing standards,and selecting adsorbents.After implementing these measures,hydrogen production and hydrogen recovery rates were significantly improved,unit power consumption was reduced by 11.68%,and system operation became more stable and efficient.
