FIELD: oil and gas production.
SUBSTANCE: invention refers to procedure improving fluidity characteristics of hydrocarbon stock. The procedure consists in division of hydrocarbon stock to the first and second raw stock flows, and in processing the first stock flow possessing at least one property out of density number in degrees of API below 18, viscosity above 10000 sCt (38°C) and chilling temperature above 20°C. Further, the procedure consists in cracking the first stock flow with fresh catalyst, thus forming cracking flow and dead catalyst and in regenerating dead catalyst with production of fresh catalyst, in recirculation of the said fresh catalyst; and in mixing at least part of cracking flow with the second stock flow. The invention also refers to the unit for realization of the procedure improving fluidity characteristics of hydrocarbon raw stock.
EFFECT: oil product with good fluidity characteristics such as low chilling temperature, high density in degrees of API and low viscosity.
