Abstract

In wet sulphuric acid plants, the economic analysis of replacing NaOH with H2O2 as an absorbent in scrubber systems explores the potential cost savings and operational benefits. The primary motivation for this change is the generation of H2SO4 of the reaction between H2O2 and SO2 that can be reintegrated into the plant’s system, thereby reducing effluent treatment cost and raw material cost. A detailed mathematical model was developed based on plant operational data to compare the economic performance of both absorbents. Results indicate potential annual cost savings of approximately 99,515 USD by adopting H2O2, demonstrating its economic advantage. Further analysis, including environmental impact assessment and operational considerations, is necessary to comprehensively evaluate the overall feasibility of implementing H2O2 as an absorbent in industrial settings. The integration of H2SO4 by-product into the Acid Production Plant for acid dilution when replacing NaOH with H2O2 as the scrubber absorbent offers multiple advantages.
