  3. Abstract:
  4. Zinc hydrosulfite is produced by slurry reaction between sulfur dioxide and zinc powder. This reaction is the first step of sodium hydrosulfite production in zinc powder processing. In this paper through performing a series of experiments, zinc hydrosulfite production rate is obtained as a function of SO2 flow rate, temperature and specific area of zinc powder. In addition, equations for predicting the end-point of the reaction and the decomposition rate of zinc hydrosulfite after that end-point are proposed. Finally, a time dependent flow rate equation is suggested to predict the maximum yield
