Abstract
The absorption of carbon dioxide or sulfur dioxide into aqueous sodium hydroxide solution has been performed in a packed column, and its application to the theory of gas absorption accompanied by chemical reaction has been studied. Furthermore, the effects of the heat of solution and heat of reaction on gas absorption rate have also been investigated. The experimental values of reaction factor, which were evaluated from Eq.(7) by using the mean values of temperature and concentration at the top and the bottom of the column respctively, were in good agreement with theoretical values within an error of 30%, even though the liquid temperature difference between the inlet and the outlet of the column was as high as 30°C. Thus, the overall reaction factor in the packed column may be evaluated from Eq.(7) for other reaction systems.
