Experimental determination of dissociation constant, Henry's constant, heat of reactions, SO2 absorbed and gas bubble–liquid interfacial area for dilute sulphur dioxide absorption into water
چکیده انگلیسی

The experimental results for dissociation constant, Henry's constant, heat of reactions and gas bubble–liquid interfacial area for absorption of dilute SO2 (SO2 partial pressure upto 0.963 kPa) into water in bubble column are presented. The relations between Henry's constant versus temperature and dissociation constant versus temperature have been proposed based on the present experimental investigation. The temperature dependence on gas bubble–liquid interfacial area per unit volume of liquid has examined. Result shows a very small decrease in interfacial area with increase in temperature. The experimental results are used to correlate total SO2 absorbed at saturation as function of temperature and SO2 partial pressure. Comparisons between experimental results and literature data have also been made at different temperatures. The reasonable fittings between the data obtained from correlation and literature data shows that the proposed correlation can be successfully used for predicting the absorption equilibria of dilute SO2 in distilled water at different temperatures.
