sulfuric acid from fluorogypsum


The dilution of sulfuric acid is exothermic, but with or without this additional heat, the lower concentration of sulfuric acid will result in conditions unsuitable for mild steel or 316L. Under such conditions, materials such as Alloy 20 can offer good resistance over a wide range of acid concentrations. Figure 3 illustrates the typical ...

Sulfuric acid ( H2SO4) - also known as hydrogen sulfate - is applied to produce fertilizers and many chemical products (detergents, phosphoric acid). It is also largely used in metal treatment for pickling and chromating. At last, sulfuric acid is employed for producing both explosives and in batteries - particularly for lead car batteries.

Sulfuric acid (sulphuric acid) is a corrosive mineral acid with an oily, glassy appearance that gave it its earlier name of oil of vitriol. Other names are sulphine acid, battery acid, and hydrogen sulfate. The sulfuric acid formula, H2SO4, indicates the presence of a sulfur atom surrounded by two hydroxide compounds and two oxygen atoms.

Bulk sulfuric acid is normally transported and stored in concentrations which can be readily handled by carbon steel. Concentrations from 88% to 99.5% with velocities below 2 feet/second and temperatures below 120° F will leave carbon steel virtually unattacked. These conditions also describe the parameters associated with many storage tanks.
