摘要
运用化工流程模拟技术对船舶烟气海水脱硫过程进行模拟.结果表明,在相同的操作条件下,脱硫效率随烟气中SO2体积分数及海水温度的升高而减小,而随填料高度及液气比的增加而增加;脱硫后的海水pH波动较小,通常在3.7~4.3之间;与海水直接喷淋相比,增加预喷淋脱硫效果更好.
The desulfurization process of shipborne flue gas by seawater is simulated by means of chemical process simulation technology.Simulation results show that under the same operating conditions,the desulfurization efficiency decreases with the increases of SO2 concentration in shipborne flue gas and seawater temperature,but increases with the increases of packing height and liquid-gas ratio.The p H value of seawater after desulfurization changes a little,between3.7 and 4.3 usually.Compared with seawater directly spraying,adding pre-spraying has better desulfurization efficiency.
