摘要
为了提升克劳斯硫回收装置对于处理低H 2S浓度酸气的适应性,主燃烧炉采用富氧空气燃烧成为提高炉温、提升酸气火焰稳定性的有效措施。为深入了解富氧燃烧效果、研究富氧燃烧工艺路线及不同富氧浓度对主燃烧炉温度的影响,借助富氧燃烧测试平台开展现场试验,确立不同工况下富氧燃烧的工艺路线,系统研究不同富氧浓度对提升主燃烧炉温度的作用。此外,还对比分析了其它提升主燃烧炉温度的方法。通过富氧燃烧工艺及其他提升主燃烧炉温度方法的对比分析,得出最优的富氧燃烧工艺路线,并推荐了提升克劳斯硫回收装置主燃烧炉温度的方法原则,为工业化应用提供支持。
To improve the adaptability of Claus sulphur recovery system on handling low H 2S content acid gas,supplying oxygen enriched air to the main furnace is an effective way of increasing furnace temperature and stability of acid gas flame.In order to better understand the effect of oxygen enriched air on combustion,and study the process of oxygen enriched combustion and the impact of different oxygen concentration on combustion temperature,this paper carried out field tests using actual oxygen enriched air combustion test rig.These tests followed systematic approach to assess how different concentration of oxygen enriched air can increase main furnace temperature,at different operating conditions and combustion processes.This paper also conducted a literature search to compare and analyse other methods of raising main furnace temperature.Through the above analysis and comparison,the optimum oxygen enriched air combustion process was developed.The paper recommends the method and principle of increasing main furnace temperature for Claus sulphur recovery process,to support application on an industrial scale.
