available and [H2SO4]b is the ,concentration, of acid in the bulk liquid (as mg CaCO3/l). For effluents with little or no heavy metals, the value of K is 2,45 x 10"3 min"1.cm"2; for effluents that contain significant quantities of ,iron,, a layer of Fe(OH)3 forms on the CaCO3 surfaces that causes K to decrease from the abovementioned value,

The ,high, CO 2 ,concentration, depresses the pH, promoting ,acidic, attack of the metal oxide layers. An amine that is more likely to distribute into the steam, such as cyclohexylamine, is a better choice for the system described above. However, amines with a ,high, tendency to distribute into the steam are not always the best choice.
