Енергоефективне проектування для сталого розвитку та екологічної безпеки за алгоритмами дії

Abstract

Chemical engineering for sustainable development of hydrolytic sulfuric acid (HSA) production is presented with scientific justification and characteristics of the component technical solutions, for example, according to the hierarchy: 1. Classification-identification of the contact process without intermediate absorption. 2. Processes for obtaining iron sulfate from hydrolytic acid. 3. Evaporation of hydrolytic acid with the release of iron sulfates. 4. Thermal decomposition of HSA with the production of sulfur dioxide. 5. Production of ammonium sulfate and extraction of V, Al, Ti, Cr compounds from hydrolytic sulfuric acid.
