Abstract
Single water droplets, 0.23 cm in diameter were suspended at 5.5°C in a warm (22°C) nitrogen stream (50 cm/sec) containing various concentrations of SO2 (1000–3000 ppm) and water vapor (6.8–16.9 mm Hg). In a separate series of tests, the SO2 was replaced by O2 in the 21–80 percent range. The droplets were exposed for fixed time intervals, and then removed and analyzed for total sulfur oxide or O2 content. The temperature of the droplet was monitored during the exposure time. Water vapor concentration in the bulk gas phase as well as SO2/O2 concentration determined the equilibrium saturation concentration of gas transferred to the water which was always less than that at thermal equilibrium. The rate of mass transfer was controlled by heat transfer to the droplets. A mechanism is proposed whereby hydrate formation at the water surface explains the results observed.
