摘　　要：通过确定贫液浓度及温度合理控制范围,定期检验贫液性能,确保最优脱除效果;多重过滤去除贫富液杂质,防止设备堵塞;合理设置消泡剂加入点及精准掌握加入时机,减少泡沫产生消除液泛现象;利用炉顶煤气余热产生的蒸汽作为贫液再生能量,在系统中增加贫富液换热器和再沸器降低能耗等一系列有效技术及控制措施,实现了氢基竖炉循环气中CO_(2)的有效脱除和能耗降低,为实现氢基竖炉顶气循环利用及氢冶金高效生产奠定了基础。By determining the reasonable control range of lean liquid concentration and temperature,the performance of lean liquid is checked regularly to ensure the optimal removal effect;Impurities are removed from rich and poor liquids by multiple filtration to prevent equipment blockage;Reasonably set defoamer adding point and accurately grasp the adding time to reduce foam and eliminate flooding;By utilizing the steam generated by the waste heat of the top gas as the energy for lean liquid regeneration,a series of effective technologies and control measures such as adding lean and rich liquid heat exchangers and reboilers in the system to reduce energy consumption have been implemented,effectively removing CO_(2) from the circulating gas of the hydrogen based vertical furnace and reducing energy consumption.This has laid the foundation for achieving the circular utilization of hydrogen based vertical furnace top gas and efficient production of hydrogen metallurgy.
