Abstract
Promoting more effective countermeasures that is really able to eliminante the offensive odor injury, actually, caused by complex of odoriferous gases, almost of them are very low concentration, is a pressing need today. Most of the controling methods or techniques apllied up to now generally have doubts about the substantial efficiency, because they have no regards for such aspecial characteristics of odor.
Paying attention to solving some of those characteristics of odor, we made experiments on absorption of hydrogen sulfide (H2S) in hydrated sodium (NaOH) solution flowing on the wirenetting of 9 mesh. And, as the result of the work, we got the following conclusios;
i) When the concentration of H2S is under than 2.0 ppm, the absorption rate of H2S gas in NaOH solution is in proportion to the interface concentration of H2S and independent of NaOH concentration.
ii) When SO2 and H2S gas simultaneously react with NaOH of liquid phase instantly, the function of absorption rate of H2S “NA” is shown as follow:
_??_
where the coefficient ‘a’ is constant that is given by the function of such as the diffusivity of th absorbed component, and we got a=0.0029 from this work.
