Exhaustive Hydrotreating of Vacuum Gasoil in a G-43-107 Unit

The capabilities of promising domestic catalysts in mild hydrocracking were demonstrated based on the results of pilot tests and industrial use. Data are reported on use of RK-442 mild hydrocracking catalysts in the conditions of the hydrotreating section in the G-43-107 hydrotreating unit at Ufa Refinery OJSC. The technologies for loading the catalyst and placing it in the operating regime are described.     

Domestic Technologies and Catalysts for Hydrotreating of Crude Oil Cuts: Experience in Use

Different methods of catalyst activation are analyzed and their advantages and disadvantages are noted. The possibilities of utilizing the design features of the units and the composition of the refined feedstock for obtaining petroleum products with a low sulfur content and aromatic hydrocarbons is demonstrated on real examples. The possibilities of promising domestic catalysts are indicated.     

Modernization of Cat Cracking Section Fittings in the G-43-107M/1 Unit

Modernization of the fittings in the catalytic cracking reactor unit in the combined G-43-107M/1 plant are described, with introduction of improved feedstock injectors, air- and steam-distributing equipment, and erosion-resistant critical-speed nozzles which allowed increasing the time of operation of the plant between overhauls to two years and the yield of naphtha cut.     

New Catalysts for Hydrorefining of Crude Oil Cuts. Experience in Use

The results of using new catalysts of hydrogenation processes in oil refineries are reported. These catalysts were developed at KATAKhIM Corp. Ltd. and are manufactured by Industrial Catalysts Closed Joint—Stock Company (Tyumen Oil Company) under the brand name RK. Experience in using them in catalytic systems utilizing domestic technologies demonstrates the possibility of manufacturing environmentally clean diesel fuel that satisfies international requirements.
