Sample text

5%. The total production of pure sulfur trioxide in India can be estimated as about 300,000 MTs in the year 2003; 60% of the production is for captive use. 2 Manufacture The manufacture of liquid or gaseous SO3 is carried out by boiling 25–32% oleum as in the case of manufacturing 65% oleum. The sulfur trioxide can be liquefied by condensing at 43–45 °C. Care should be taken to prevent any moisture ingress in the plant as it may cause serious operating problems. The liquefied SO3 is then taken to a product storage tank from which tankers are filled using intermediate lorry filling tanks.

This will also require lower volumes of gases to be handled, thus reducing power consumption. Cesium activated catalyst is used to give stack emissions of 150 ppm SO2 as against the 500–700 ppm permitted by the Environment Protection Agency of USA. Air injections will be provided at appropriate places in the conversion system. A separate acid circuit will be provided for the final absorption tower to minimize SO2 content in the stack. The drying tower and interpass absorption tower will have a common acid circuit.

Water preheating in the end absorption from 40 to 80 °C. 1 Summary Sulfuric acid is called the king of chemicals. The first step to produce a useful product is sulfonation. Since the direct use of sulfuric acid is not feasible in all applications, the following auxiliary agents do play an important role. Chloro-oleums 8. Sulfamic acid 10. Methane sulfonic acid Outotec from Germany are suppliers of technology for large size (5,000 tonnes per day (TPD)) sulfuric acid plants and have innovated processes for sulfonation.
