摘要
介绍了我国SO3磺化技术的发展现状及SO3磺化装置废热回收的现状;介绍了SO3磺化工艺过程废热回收方案;分析了SO3磺化工艺过程废热回收装置运行经济效益分析;分析了磺化工艺过程废热回收换热器使用寿命短的原因,提出了解决设备在应用和推广中使用寿命短的技术难题,对换热器进行材料、结构等方面的改进,使换热器寿命大大延长,节能减排的同时,获得了很好的经济效益,符合国家节能政策,今后将得到更大的应用与发展。
SO3 sulfonation technology development status and SO3 sulfonation plant waste heat recovery status of ourcountry were introduced. The SO3 sulfonation process waste heat recovery scheme was introduced. The SO3 sulfonation process waste heat recovery unit operation economic benefit and the sulfonation process waste heat recovery heat exchanger used in the short life of the reason were analyzed. Some solve equipments in application and popularization of the technical problem of short service life of heat exchanger, material, structure and other aspects of the improvement were put forward. The service life of the heat exchanger was greatly prolonged and good economic benefits abtained.
