  • 摘要: 建立了一套中试规模的船舶废气脱硫装置，并通过实船实验对比研究了海水法、镁法和镁基-海水法在船舶废气脱硫系统中的应用。研究结果表明，镁法与镁基-海水法的脱硫效率保持在95%左右；海水法开始时脱硫效率能达到90%，40 min内迅速下降至60%；海水法pH下降迅速，而镁法和镁基-海水法pH下降较平缓，且镁基-海水法的pH较镁法更稳定；镁基-海水法喷淋液中碳酸盐总量不减少，不释放CO2。综合分析认为，镁基-海水法是一种具有广阔应用前景的船舶废气脱硫技术。
    Abstract: A pilot-scale marine exhaust gas desulphurization equipment was established and ship trial was conducted to compare seawater system,magnesium system and magnesium-base seawater system.The test results showed that the desulphurization efficiency of magnesium and magnesium-base seawater was kept highly at 95%.The initial desulphurization efficiency of seawater was 90%,but decreased rapidly to 60% in 40 minutes.The pH value of spray liquid in seawater system dropped fast.While both in magnesium and magnesium-base seawater systems,the pH value of spray liquid declined more slowly.The pH value of spray liquid in magnesium-base seawater system was more stable than that in magnesium system relatively.There was no extra CO2 emission from magnesium-base seawater system because no decreasing on total carbonate in spray liquid was observed.Comprehensive analysis reveals that there would be broad prospects in the application of magnesium-base seawater system to marine exhaust gas desulphurization.
