Methods of regulation of sulfur contents at intermediate stages and in products of oil stock processing

Mathematical models of distribution of charge flows at oil-processing plants, allowing to optimize sulfur contents at intermediate stages and end products, are offered in the paper. The possibility of sulfur contents redistribution in various products by modifying technological parameters of oil products processing and by changing the directions and (or) the volume of the flows, is shown. This allows to cut down the cost of sulfur refinement and reduce the pollution made by sulfur-containing gas.
