摘要
Abstract
An experimental packed tower for amine-based flue gas desulfurization was designed in this paper.The effects of main operating parameters on the efficiency of SO2 absorption into ethylene diamine/phosphoric acid solution were investigated.The results show that desulfurization efficiency increases with increasing liquid-gas ratio and packing height,and declines with the increase of empty tower gas velocity,inlet SO2 concentration and S (Ⅳ) concentration of lean solution.The desulfurization efficiency is significantly influenced by empty tower gas velocity and S (Ⅳ) concentration of lean solution.Under experimental conditions,the high effective utilization of packing can be achieved when liquid-gas ratio is more than 1.73L/m3 and S (Ⅳ)concentration of lean solution is less than 0.1 mol/L.The liquid-phase mass transfer resistance decreases with increasing absorbent flow rate or decreasing S (Ⅳ) concentration of lean solution.关键词
