RESULT OF EXPERIMENTAL TESTS CONDUCTED TO EXPAND THE RAW MATERIAL BASE AND IMPROVE THE QUALITY OF ISOMERATION PLANT PRODUCTS

This article proposes ways to increase the octane number of the isomerate and increase the volume of plant feedstock by isomerizing pentane-hexane hydrocarbons. Modern changes in requirements for petroleum products in the country and coordination of the direction of development of the country's oil refineries and improving the quality of petroleum products, the use of new technologies such as hydrogen purification, alkylation, catalytic cracking, catalytic reforming, isomerization, etc. are becoming a fundamentally important link in oil refining. Over the past ten years, the efforts of the commonwealth of Independent States countries to replace old and obsolete equipment with new ones produced abroad and in distant countries, as well as the transition to European quality of transport fuel, have made it possible to use new methods of processing petroleum raw materials in our country, as well as to offer new domestic methods. The described technological method is aimed at improving the isomerization unit operating in practice; experimental and testing work was carried out in the central laboratory of the plant and tested in the specified production. Relevant research work related to production and the specified technological method was carried out with the participation of highly qualified specialists from the specified plant. The lack of research institutes and centers in the country, the weakness of scientific and business ties between industry and the research center, as well as the weak interest of financial companies supporting new methods invented by individual authors are a significant obstacle to conducting research in various directions. Test work was carried out at the “light naphtha isomerization” installation with an annual capacity of 600 thousand tons/year, which is part of the integrated installation LK-6u, which is an integrated installation of the Shymkent Refinery (Petro Kazakhstan Oil Products LLP). The main goal of the experiment is to obtain high-quality gasoline that meets Euro-4 and Euro-5 requirements by increasing the volume of raw materials and the temperature regime of the splitter column.
