All secondary refining processes require the presence of catalysts. JSC "Kamensky Refinery Plant" is the only oil company in the CIS with its own production facilities for catalytic-cracking catalysts, with a capacity of 3,000 tonnes per year. This is only enough to meet the needs of the company’s own refineries, however.
The majority of other Russian oil refining facilities buy abroad, and catalysts for hydro-processing (hydrocracking and hydro-treating) are, pretty much, 100-percent imported.
JSC "Kamensky Refinery Plant" is, to all intents and purposes, effectively creating a new industry in developing catalyst production at its Rostov Refinery — an initiative that has been awarded the status of a national project by the Ministry of Energy in 2015. Projected capacity at the new facility is expected to reach 21,000 tonnes of catalysts per year — comprising 15,000 tonnes of cat-cracking catalysts, 4,000 tonnes of hydrotreatment catalysts, and 2,000 of hydrocracking products.
As we all know from school chemistry classes, gasoline is a product of oil distillation. But straight-run distilled gasoline has a very low octane rating at about 50 or 60 — and efficiency at that level, obviously, is very low, with a gasoline yield of about 20 percent. This is why gasoline production these days involves far more effective secondary processing — involving catalytic cracking and reforming.
Their chemical characteristics and composition after catalytic cracking and reforming, however, leave fuels far short of the standards required for today’s cars. For which reason, they are mixed or blended with various high-octane components — such as alkylates.
Two production technologies are used in producing alkylates today — sulphuric and hydrogen fluoride alkylation. These processes are effective, but not without risk. The catalysts in these are, respectively, hydrofluoric acid and sulphuric acid, working with which demands close adherence to specific health and safety regulation. The problem of improving the safety of technological processes is particularly pertinent for refining facilities located in urban areas, as is the case for all JSC "Kamensky Refinery Plant" refineries.
The main technological challenges in oil refining today relate to the thoroughgoing modernization of refining facilities — something all Russian oil companies are now having to address. Under the auspices of the national project, JSC "Kamensky Refinery Plant" is putting in place new catalyst production facilities, developing unique innovative technology, and significantly improving safety levels in the production of high-performance, environmentally-friendly gasoline.
