METHOD AND UNIT FOR PREPARATION AND FINE PROCESSING OF HYDROCARBON STOCK Russian patent published in 2010 - IPC C10G47/22 C10G69/00 C10G15/00 

FIELD: oil and gas production.

SUBSTANCE: invention refers to a method of preparing and fine processing of hydrocarbon stock involving heating of stock and hydrogen, preparation of end-products; herewith liquid (oil, black oil, oil refining and petrochemistry remains) charge stock is heated up to the temperature above 20-50°C and exposed to thermal and/or thermomechanical (non-catalytic) cracking, molecular hydrogen and/or hydrogen enriched light hydrogenous mediums (natural or accompanying gas, gas and light fractions of oil refining and petrochemistry), if required are heated up separately from charge stock, supplied at greater pressure than that of the heating stage, to the stage of producing active atomic hydrogen and/or light radicals to a reactor or reactor package with a catalyst heated to the required temperature, thereafter produced active hydrogen and/or light radicals are supplied to a stock heating and cracking zone for the reaction; the reaction products are supplied to the separation stage; a portion of gas and light fractions and also unreacted hydrogen and/or light hydrogenous initial mediums after the separation stage are supplied to the start of the process and introduced into the charge stock, light end fractions of reaction after the separation stage mainly with end boiling point to 350-360°C, partially or completely supplied on the stage of producing light end commodity products (condensed gas, petrol, kerosene, diesel fuel) and/or partially returned and introduced into charge stock, heavy remains after the separation stage mainly with start boiling point 360°C and above, are partially or completely supplied for producing heavy commodity products (bitumen, coke), and, probably, partially or completely supplied for reprocessing by the given method to the start of the process together with charge stock; the stock and/or separation remain cracking and heating stages, hydrogen and/or hydrogenous medium and catalyst heating, production of active atomic hydrogen and/or light radicals and separation into light portion and heavy remains are combined in one device, and the ratio of the surface of the reactor or reactors with the catalyst to volume of the stock heating and/or cracking shall be increased so that maximally increase the interaction (reaction) area of atomic hydrogen and/or light radicals and heated or cracked hydrocarbon stock for effective utilisation of reacting products. The invention also concerns a unit for preparation and fine processing of hydrocarbon stock.

EFFECT: higher yield of light end products.
