In the pulp and paper plants, various chems. including strongly acidic/alk. substances, are utilized in manufacturing processes and waste treatment.For instance, sulfuric acid is used for pH adjustment in the bleaching process, neutralization of alk. waste.Because of its large amount of usage and low-cost perspective, concentrated sulfuric acid is generally used with dilutionHowever, dilution of sulfuric acid is a highly exothermic reaction, which involves the potential risk of a serious accident.It is critical to select optimal control systems, corrosion-resistant pumps, and cooling systems in order to achieve safe, reliable dilution of concentrated sulfuric acid.
