摘　　要：本文开展了高炉煤气精脱硫新技术的开拓性探索试验研究,以解决困扰钢铁企业清洁生产的一大难题。基于醇胺溶剂法的脱硫原理,采用碱洗预处理和醇胺溶剂吸收再生工艺流程,有效解决了高炉煤气杂质和温度对溶剂和系统的影响。本试验对影响高炉煤气精脱硫的主要影响因素进行了探索,发现再生塔温度和贫液液气比是影响脱硫效果的主要因素,其最佳值分别为110℃和1.9 L/m^(3),在最佳工况条件下,净化后高炉煤气总硫含量可稳定控制在10 mg/m^(3)以下,远低于钢铁行业超低排放要求。通过该试验研究结果可知,醇胺溶剂吸收法可以高效地脱除高炉煤气含硫组分,具有极大的推广应用价值,同时,也为进一步工业化应用提供了数据支撑和工程经验,对高炉煤气精脱硫的技术发展开拓了新路径。This article conducts pioneering exploration and experimental research on new technologies for fine desulfurization of blast furnace gas,in order to solve the major problem that troubles clean production in steel enterprises.Based on the desulfurization principle of alcohol amine solvent method,the process flow of alkali washing pretreatment and alcohol amine solvent absorption regeneration is adopted to effectively solve the influence of impurities and temperature on the solvent and system in blast furnace gas.This experiment explored the main influencing factors on the precision desulfurization of blast furnace gas,and found that the temperature of the regeneration tower and the lean liquid to gas ratio were the main factors affecting the desulfurization effect.The optimal values were 110℃ and 1.9 L/m^(3),respectively.Under optimal operating conditions,the total sulfur content of purified blast furnace gas can be stably controlled below 10 mg/m^(3),far below the ultra-low emission requirements of the steel industry.According to the research results of this experiment,it can be concluded that the alcohol amine solvent absorption method can efficiently remove the sulfur-containing components of blast furnace gas,which has great promotion and application value.At the same time,it also provides data support and engineering experience for further industrial application,and opens up new paths for the development of blast furnace gas fine desulfurization technology.
