Claim:
An oil refining system of thermal processes for fine fractions in the field of inertia forces with utilization of vortex separators, vortex vapor generators, and vortex vapor condensers for separation of liquids with different densities and/or different boiling temperatures, which permits obtaining fine uniform oil products by both thermal distillation and cracking at significant simplification of construction elements of said system comprising: (a) a unit of preliminary oil purification from admixtures, water and satellite gases contained in crude oil; said unit of preliminary oil purification including: a reservoir, or pipeline with crude oil; a pump for crude oil supply into a vortex separator for separation of oil from water and other admixtures; a coarse filter for purification from mechanical admixtures; a heat exchanger for preliminary heating of crude oil with a purpose of reducing viscosity of said crude oil; a vortex separator for separation of oil from satellite gases, water and dissolved in said crude oil salts; pumps for oil supply to consecutive units for its separation for fractions and water removal into extraction systems for recovery of useful products; for enhancing of a crude oil purification a separate process can be performed in two vortex separators in series; (b) a second unit assigned for deep oil separation for fractions consisting of consecutive stages of heating, evaporation of initial oil and residual products of thermal separation including: intermediate furnaces, or heat exchangers for heating of initial product to temperatures corresponding to release of fraction of given composition (close to a boiling point of a particular fraction); vortex vapor generators providing intensive process of evaporation in volume of rotating liquid; a pump utilized for extraction of evaporation products into condensers and transfer of not evaporated liquid into a consecutive stage of fraction evaporation; a vortex vapor condenser for gas products of oil distillation with corresponding cooling system of its construction elements; a condensation heat can be utilized for preliminary heating of crude oil, or for intermediate stages of oil separation for fractions; liquid products from vortex vapor condensers of separate stages are supplied by a pump into corresponding reservoirs.
