ons offered by governments to locate in a particular region?The final decision on where the sulfuric acid plant really involves a careful examination and a compromise among all of the factors that have been discussed above.Producing Sulfuric AcidSulfuric acid is produced by two principal processes-the chamber process and the contact process.The contact process is the current process being used to produce sulfuric acid. In the contact process, a purified dry gas mixture containing 7-10% sulfur dioxide and 11-14% oxygen is passed through a preheater to a steel reactor containing a platinum or vanadium peroxide catalyst. The catalyst promotes the oxidation of sulfur dioxide to trioxide. This then reacts with water to produce sulfuric acid. In practice, sulfur trioxide reacts not with pure water but with recycled sulfuric acid.The reactions are:2SO2 + O2 * 2SO3SO3 + H2O * H2SO4The product of the contact plants is 98-100% acid. This can either be diluted to lower concentrations or made stronger with sulfur trioxide to yield oleums. For the process, the sources of sulfur dioxide may be produced from pure sulfur, from pyrite, recovered from smelter operations or by oxidation of hydrogen sulfide recovered from the purification of water gas, refinery gas, natural gas and other fuels.Battery Acid IndustryMany industries depend on sulfuric acid. Among these industries is the battery acid industry.The electric battery or cell produces power by means of a chemical reaction. A battery can be primary or secondary. All batteries, primary or secondary, work as a result of a chemical reaction. This reaction produces an electric current because the atoms of which chemical elements are made, are held together by electrical forces when they react to form compounds.A battery cell consists of three basic parts; a positively charged electrode, called the cathode, a negatively charged electrode, called the anode, and a chemical substance, called an electrolyte,...
