Production Of Ammonia

Today, one of the most widespread processes in modern oil refining is the production and purification of hydrogen, which is used in the production of ammonia, methanol, and plastics. Without it, the production of high-quality motor fuels is impossible, since this gas is involved in the hydrogenation process (hydrotreating) [1]. Currently, at oil refineries and petrochemical plants, hydrogen is obtained in two ways: from natural gas by steam reforming into a mixture of hydrogen and carbon monoxide (synthesis gas), in a catalytic reforming unit, where a mixture of hydrogen and light hydrocarbon gases (hydrogen-containing gas) is released. Most modern oil refineries have a hydrogen production unit, its widespread use in industry is explained by its chemical activity, ease of production and high exothermicity of the process [2].

This paper investigates the problems of increasing the efficiency of technological installations of oil refineries, which produce high-octane and environmentally friendly motor fuels. We used methods of mathematical modeling and fuzzy mathematics to maximize the volume of gasoline produced and improve its quality indicators, taking into account the imposed restrictions. On the basis of a systematic approach, an effective methodology is created for the development of a package of models of interconnected plant units using available information of a different nature, including fuzzy information. The resulting package of models makes it possible to systematically simulate the work of the unit under study and to increase the efficiency of the facility by increasing the volume of manufactured target products and improving its quality indicators. There are presented results of the analysis and expert assessment of the catalytic reforming unit LG-35-11/300-95 and the choice of the optimal type of model for individual units. A scheme is being created for combining the developed models into a single package of models. On the basis of the proposed methodology, hybrid models are being developed that make it possible to determine the volume of produced catalyzate and its quality indicators.
