The most effective in terms of technical and economic performance are flow charts of concentration of sulfuric acid bubble and drip type. In such installations, and water vapor flow rate is significantly lower than in plants with vacuum concentrators. For the regenerated sulfuric acid concentration in the bulk production of sulfuric acid cleaning process of benzene at JSC "Zaporozhkoks" (250-450 tons / month) is suitable only installations using vacuum concentrator. In developing such a scheme appropriate to provide a stage extracts evaporated acid 280 0С for the decomposition of organic impurities. Product Description popup.authors Белонощенко В.П.
