摘要
结合近年来国内外硫磺回收工艺发展特点,总结了川渝地区硫磺回收工艺开发及发展规律,并展望了硫磺回收工艺发展趋势。通过比较在线工艺特点及应用现状,提出了工艺改进和工艺设计发展方向。针对川渝地区现有硫磺回收工艺逐渐满足不了国家的环保要求,提出了对关键设备的改进与再设计,以克服制硫工艺中动力学与热力学的矛盾问题。提出新型低温催化剂的研制,以达到节能减排的目的。提出对现有工艺各种优点进行合理组合的思想,对制硫工艺进行优势互补,以提高工艺稳定性和硫磺回收率。有助于硫磺回收及尾气处理新工艺流程的深入开发和研究。
Taking into condition the development of the sulfur recovery process at home and abroad in recent years,the law of the development of the sulfur recovery process in Sichuan and Chongqing is summarized,and the prospect of the sulfur recovery technology trends is discussed.By comparing the characteristics and application of online technology,the process improvement and the process design development are proposed.Because the process of existing sulfur recovery can not meet the state′s environmental requirements in Sichuan and Chongqing area,the paper presents the key equipment for the improvement and re-designs process to overcome the condition between dynamics and thermodynamics in sulfur recovery process.In order to achieve the purpose of energy saving,the paper proposes a novel low-temperature catalyst for the development.Put forward the idea of combining the advantages of existing technology so as to improve the process stability and sulfur recovery.It is benefit to the new sulfur recovery and tail gas treatment process for further development and research.
