【摘要】 研究用软锰矿的水悬浮液脱除一转一吸硫酸生产尾气中的ＳＯ２并副产工业硫酸标的工艺可行性。从技术经济的角度将这种脱硫方法与改造为二转二吸流程以及传统的工业硫酸锰生产方法──硫酸法进行了分析比较，结果表明该方法具有较好的经济效益和社会效益。更多还原

【Abstract】 The technological feasibility of SO2 removal from tail gas of single-absorption H2SO4 plant with aqueous pyrolusite suspension as absorbent and commercial MnSO4 as byproduct is examined. The process is compared with retrofitting to doubleabsorption H2SO4 plant and conventional H2SO4-based MnSO4 plant on tech-economic grounds. The results show its superiority both in economic and environmental benefits.更多还原
