摘要

摘要: 为研究船舶混合模式脱硫过程中使用海水脱硫的主要参数（废气量、入口二氧化硫浓度、液气比）以及使用碱液脱硫的主要参数（循环液pH、废液排出量、液气比）对脱硫塔脱硫效率的影响，使用化工流程模拟软件Aspen Plus V10对W6X35型船用柴油机废气填料塔脱硫过程进行了模拟分析并根据模拟结果对运行参数进行了优化。模拟结果表明：海水脱硫时，液气比是重要调控参数，应根据负荷、油含硫量变化相应地在3～7 L/Nm³范围内调节合适的液气比。碱液脱硫时，废液排放量是一个重要参数，对脱硫效率、亚硫酸钠饱和结晶及废水处理量影响大，运行时应控制在0.105～0.152 kg/kW·h范围内并维持在低值；循环液pH、液气比对脱硫效率和运行经济性影响较大，循环液pH以6.5为宜、液气比以3～4 L/Nm³为宜。

Abstract: In order to investigate the impact of the parameters of seawater desulfurization process, such as exhausted air quantity, inlet SO₂ concentration and liquid to gas ratio, and the parameters of alkaline liquor desulfurization process, such as pH value of Circulating liquid, waste liquid discharge, liquid to gas ratio, on the efficiency of desulfurization tower, simulation of desulfurization process in the packing tower for W6X35 diesel engine is carried out by means of chemical process simulation software Aspen Plus V10. The parameters are optimized through the simulation. The simulations reveal that, for seawater desulfurization, the liquid to gas ratio is an important control parameter, that should be adjusted within the range of 3～7 L/Nm³ according to processing load and fuel sulfur content, while for alkaline liquor desulfurization, waste liquid discharge has the greatest impact on desulfurization efficiency, Na₂SO₃ crystallization from the saturated solution and waste liquid treatment load and should be adjusted within the range of 0.105～0.152 kg/kW·h, the lower end being preferable. pH value of circulating liquid and liquid to gas ratio affect the desulfurization efficiency and operation economy rather significantly and preferred values are 6.5 for pH value of circulating liquid and 3～4 L/Nm³ for liquid to gas ratio.
