Contact oxidation of sulfur dioxide

Course work in discipline "Constructional materials technology of inorganic substances" on "Contact oxidation of sulfur dioxide" Explanatory note 21, p. 1 Annex 3 links. The physical and chemical bases of contact cleaning sulfur dioxide, presented the technological scheme of the process. These drawings technological scheme. The choice of construction materials processing equipment and the equipment. Contact LIPID sulfur dioxide, vanadium contact mass, contact KNOT To contact the housing apparatus used two-layer sheet steel with ВСт4кп with 12X18H10T layer. The protective lining is done with fireclay bricks, asbestos, silica putty. Case heat exchanger made of carbon steel 12Х17, 15Х28, 15Х6СЮ. The protective lining is performed with acid resistant tiles, patching silica.
