Abstract: The article analyzes and summarizes the technical measures for saving energy, reducing pollution emissions in the production of hydrogen peroxide in recent years, by referring to the author’ s production practice. The technical measures include mainly adding hydrogenation liquid / working solution heat exchanger, omitting the oxidation liquid pump and phosphoric acid pump, improving the utilization of air and hydrogen, disposing of reasonably the oxidation residue, recoverng oxidation tail gas by an energy-saving way, recycling condensed liquid on the top of the concentration unit. Such information may provide some reference for hydrogen peroxide production and equipment design.
