Kinetics of sodium bisulfite formation from "poor" sulfur-containing waste gases of pyrometallurgical productions in carbonate solution

Article preview

Studies of the process of sulfur dioxide utilization with the production of bisulfite reagent from waste gases of various pyrometallurgical shops of copper and nickel plants have been carried out. The linear character of kinetic curves of sodium hydrosulfite formation in the range of its concentrations in solution from 0 to 400 g/dm3 has been established as a result of investigations. It was determined that the dependence of the reaction rate constant on the gas flow rate obeys the parabolic law. Graphical dependences of solution pH and concentration of sodium bisulfite in it are plotted. It is shown that at pH decrease from 8.5 to 5.0 the concentration of sodium bisulfite linearly increases, and at pH<4.5 - its decrease is observed.
