Scheme of catalytic cracking installation

Catalytic cracking is the thermal catalytic processing of petroleum fractions to produce valuable products. Catalytic cracking is the most important large-scale process of oil refining. The global capacity of the constructed cracking plants is more than 770 million tons / year Raw materials and products As raw materials, the plant can receive: Vacuum gas oil from the vacuum units of the AVT installations An inverted residue from the hydrocracking unit Filtrates and extracts from the gas oil production units of the delayed coking unit, etc. Fuel oils from the AVT units in mixtures with vacuum gas oil. If there is a vacuum gas oil hydrotreatment unit in production, additional hydrotreatment of the resulting gasoline may be required to meet its Euro-5 requirements. The products of the plant are: Dry gas - the raw material of desulfurization plants. Liquefied petroleum gases (propane-propylene fraction (PPF) and butane-butylene fraction (BBF) are the raw materials of MTBE and sulfuric acid alkylation plants. High-octane component of gasoline (OCHIM 90-92) Light catalytic gas oil is the raw material of diesel fuel hydrotreating plants, the component of commercial fuel oil. Heavy catalytic gas oil is a raw material for the production of carbon black, the component of fuel oil. SVSG is the raw material of sulfur and sulfuric acid production plants.
