• 中文摘要： 本研究在常溫下以1.0N鹽酸溶液液滴在吸收管中降落而吸收二氧化硫的實驗,測定液滴之液相物理質傳係數。液滴直徑為0.279和0.444cm。氣體混合物包含3,000或9,000ppm濃度之二氧化硫、飽和水蒸汽和氮氣。實驗結果發現,液滴之液相物理質傳係數與氣相二氧化硫濃度、液滴降落速度和降落時間無關。將實驗數據與各種液滴液相質傳係數預測模式比較,結果顯示:在0.06至0.6cm液滴直徑的範圍內,本實驗和前人之數據與穿透模式(或忽略表面伸展幅度之效應的表面伸展模式)之預測吻合,而在此模式中,液滴表面之生命期是在1至3個液滴振盪週期之間(平均值為1.64個週期)。
• 英文摘要： The absorption of SO/sub 2/ into drops of 1.0N HCl solution was studied in an absorption column at room temperature to determine the liquid-phase physical mass transfer coefficients. The diameters of drops were 0.279 and 0.444cm. The gas mixture consisted of 3,000 or 9,000ppm SO/sub 2/, saturated water vapor, and nitrogen. The liquid- phase physical mass transfer coefficients of drops were found to be independent of gas phase SO/sub 2/ concentration, drop falling velocity, and contact time. Experimental data were compared with predictions of different models. For drops in the size range of 0. 06 to 0.6cm dia., the data of this study and those available in the literature agree well with the penetration model, or the surface stretch model without the effect of the amplitude of the surface stretch, with drop surface lifetimes being in the range of time for one to three cycles of drop oscillation with a mean value of 1.64 cycles.
