Manufacture Of Sulfuric Acid

------------------------------------------------- Manufacture of entropyic Acid: The contact Process entropyic erosive is trace using the Contact process. sulfuric blistering is construct via sec dioxide. The raw materials be sulphur, air (oxygen) and water. in that respect are three stages in the process. The main stages in the meet of sulfuric acid Stage 1: S(s) + O2 (g) ? SO2 (g)  Sulphur dioxide is made by fire sulphur in air or oxygen in a combustion chamber. Sometimes weightlift disulphide is burned in air instead. The sulphur dioxide is purified to remove impurities that would modify the throttle at later stages. Stage 2: Sulphur dioxide + Oxygen  Sulphur trioxide 2SO2 (g) + O2 (g)  2SO3 (g) The sulphur dioxide is then converted to sulphur trioxide. This step is called the Contact process. Sulphur dioxide is mixed with oxygen and passed everyplace a gun (Vanadium(V) oxide: V2O5)) at 450°C at 1-2 atm. These are the optimum temperatures and pressures for the chemical reception and about 99% of the sulphur dioxide is converted into sulphur trioxide chthonian these conditions. This is a reversible reaction. The beforehand(predicate) reaction is exothermic. Increasing the temperature decreases the yield.

However, at very low temperatures, the respect of reaction is very dimmed and the time required would make the process costly. A catalyst and temperature of 450°C are apply to speed up the reaction while still achieving a reasonable yield. An adjoin in press ure would also increase the yield and the ra! te, but the be of this would be high. The catalyst speeds up the rate of both the forward reaction and the backward reaction. The catalyst causes the reaction mixture to sift its equilibrium composition more quickly. This stage takes place in the converter (c.f. catalytic converters in cars). Stage 3: SO3 (g) + water supply (l) ? H2SO4 (l) Finally the sulphur trioxide is converted to sulphuric acid. Overall, this process dejection be...If you want to get a full essay, order it on our website: OrderCustomPaper.com
