      Waste Heat Boilers - Sulphuric Acid

      Boilers in acid plants are waste heat boilers cooling gases from sulphur furnaces, regeneration furnaces and between catalyst beds. Types of Boilers. There are basically two types of boilers in common use: 1) Firetube 2) Watertube. Firetube Boilers. In firetube boilers the hot gases are confined within tuibes arranged in a bundle within a shell.

      Flue-gas desulfurization - Wikipedia

      SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime

      Low Temperature Corrosion in Boiler and Its Prevention

      The presence of moisture in the flue gas due to moisture in fuel and air, sulphur dioxide, and trioxide, combines with moisture and forms sulphuric acid and sulphuric acid. These acids condense from around 115 degree centigrade to slightly higher than 160 degrees, depending upon the concentration of SO3 and water-vapour.

      H2SO4 gas detector, Sulfuric acid, Hydrogen sulfate

      Sulfuric acid effects on health. At ambient temperature, sulfuric acid (H2SO4) is an oily, colorless and odorless (when it is a pure gas) liquid.In case of dirt, it might be yellow-brown. This very corrosive substance can cause skin burnings and severe eye damage (H314). Sulfuric acid vapors are also very harmful and can be lethal if inhaled.
