CLASSIFICATION OF OPTIMIZATION TASKS FOR REFINERIES

Abstract

Optimizing oil refineries to meet current market and regulatory demands poses significant challenges for today’s oil industry. Environmental standards make new projects more costly and complex. All operations must reduce air pollution emissions (NOX), which means costly upgrades to existing installations. The low sulfur fuel demand increases the value of the hydrogen required for its production. Competitive printing demands high performance with maximum security and production flexibility. 50 % ratio of streams passing through hydro processors for conversion, processing, and pretreatment at US refineries to total streams. Hydrodesulphurization is the largest application of catalytic technology in terms of volume of material processed. Accurate and reliable measurement of crude oil distillation columns; Calculating yield is critical for achieving production goals, planning and programming. The feed rate should be maximized while ensuring that the crude oil mixture meets environmental requirements. Furthermore, errors in measurements can result in costly downtime or out-of-spec products. The purpose of the refining process is to convert crude oil, which is a natural raw material, into salable products. Products from refineries include cars, trucks, airplanes, ships and fuel for other vehicles, fuel for heat and power generation for industrial, and domestic use, raw materials, lubricating oils, waxes, bitumen for the petrochemical and chemical industry. Special products such as energy, heat (steam), also power (electricity) can be grouped as by-products. For the production of petroleum products, raw materials are processed at different distillation plants. crude oil of these processing units, which transform them into products with the help of supporting units and facilities. This combination is called refining. Market demand for the product type, available raw quality and the requirements set by the authorities include the size, configuration, and configuration of a refinery. Affect its complexity. Since these factors vary from region to region, the facility structures of refineries are also different. These are the basic production departments, process units and auxiliary facilities of the refineries.
