VORTEX HEAT EXCHANGE UNIT FOR DEHYDRATION OF OIL AND OIL PRODUCTS AND SEPARATION OF HYDROCARBON-CONTAINING MIXTURES AND COMPOUNDS, AND METHODS IMPLEMENTING IT Russian patent published in 2012 - IPC C10G33/00 B01D3/00 B04C3/06 

FIELD: oil and gas industry.

SUBSTANCE: vortex heat exchange unit includes housing, spring vortex tubes with guides and combines vortex device with additional evaporation surface. And housing is made in the form of a jacket. Additional evaporation surface represents finning of spring vortex tubes, which is made in the form of thread. Essence of oil and oil product dehydration method consists in oil heating to water boiling temperature, extraction of free and fixed water in the form of vapour and its further removal. Oil or oil products are heated to temperature of 100-250°C and supplied to vortex heat exchange unit at high speeds and pressure of 0.6-1 MPa. Thus, it is warmed-up by transmitting some part of heat from oil or oil products to jacket, and at the same time, oil or oil products are additionally heated to the required temperature providing water evaporation process owing to friction forces and flow swirling in spring vortex tubes. Essence of separation method of hydrocarbon-containing mixtures consists in their heating to boiling temperature of low-boiling component. At that, separation of low-boiling components is performed in cavity of vortex tubes. Separation of low-boiling components is performed also when swirled fluid flow leaves nozzles and flows via finned surface of spring vortex tubes and heated walls of the jacket.

EFFECT: increasing efficiency of oil and oil product dehydration processes, as well as separation of hydrocarbon-containing mixture and compounds owing to changing the configuration and arrangement of vortex tube, reduction of metal consumption and complexity of its production, as well as reduction of power consumption owing to using the product itself during heating of vortex heat exchange unit, and by preventing mixing and carryover with axial flow of liquid phase.
