Sulfur could be produced in the middle of distillation procedure, while Sulfur content of sour oil is separating as a high-demanding by-product. Of all the hetero-elements in crude oil, sulfur has the most important effects on refining.
Sufficiently high sulfur levels in refinery streams can (1) deactivate (“poison”) the catalysts that promote desired chemical reactions in certain refining processes, (2) cause corrosion in refinery equipment, and (3) lead to air emissions of sulfur compounds, which are undesirable and may be subject to stringent regulatory controls.
Sulfur in vehicle fuels leads to undesirable vehicle emissions of sulfur compounds and interferes with vehicle emission control systems that are directed at regulated emissions such as volatile organic compounds, nitrogen oxides, and particulates.
Application of Sulfur
Sulphur is widely used as raw material in numerous applications: Sulphuric Acid, Fertilizers, pharmaceuticals, Bactericide in winemaking and food preservation and Sulphur inlay in types of furniture.
Fertilizer: Every day the fertilizers composed of Sulphur are increasing. The most important Sulphur containing fertilizer is mineral calcium sulfate. As elemental Sulphur’s hydrophobicity does not let it be used directly by plants. Soil bacteria can convert it to derivatives which are soluble that is it can then be consumed by plants. Sulphur improves the efficiency of other vital plant nutrients, especially nitrogen and phosphorus. Biologically produced Sulphur particles are naturally hydrophilic due to a biopolymer coating, they are easier to disperse over the land in a spray of diluted slurry, which results in a faster uptake.
