Mechanisms Of Dry So2 Control Processes June 1982

Test results indie that the diffusion of gaseous SO2 through the stagnant gas film is not a rate controlling step.9 It has been proposed9 that initially the rate of reaction is controlled by chemical reaction, and as the ash layer builds up, the rate of reaction becomes controlled by the diffusion of S02 through the ash layer.

Scavenging of SO2 and HCl during growth of ice …

Scavenging of HCl and SO 2 during snow-crystal growth by sublimation of water vapour from liquid droplets was studied in a cylindrical chaer housed in a cold room. The SO 2 sorption in crystals appears to be independent of the gaseous-phase concentration in the tested 1.2–7.4 ppmv range. The mean sulphur (as sullphate) concentration in crystals was S(VI) = (9.3 ± 5.5) ppm.
