摘要
(CN105480953) 本​发明​是​一种​使用​硫磺​作为​燃料​的​烷基​化​废​酸​裂解​工艺,即​烷基​化​废​酸​在​硫磺​燃烧​产生​的​高温​环境​下​裂解​生产​硫酸​的​工艺,包括​废​硫酸​在​高温​下​裂解、余热​锅炉​热量​回收、封闭​酸洗​净化、两次​转化、两次​吸收​和​尾气​吸收​等​工序,生产​出​合格​的​硫酸​产品。与​普遍​使用​的​天然气、液化气​等​气体燃料​相比,硫磺​作​燃料​的​烷基​化​废​酸​裂解​工艺​将​燃料​转化​为​产品,大大​降低​了​装置​运行​成本;避免​了​因​气体燃料​燃烧​产生​的​H<sub>2</sub>O​而​形成​的​外​排​稀​酸,避免​了​新的​废物​排放;此外,还​减少​了​因​气体燃料​燃烧​产生​的​CO<sub>2</sub>的​排放。
