Abstract

FIELD: petroleum processing. SUBSTANCE: petroleum is heated to be separated into residual fraction and vapor fraction and the latter is taken off, condensed, and collected. Fractionation is carried out by way of producing high-developed evaporation surface in vortex film evaporator in the form of thin twisted film of petroleum followed by intensive evaporation thereof upon additional steam-heating of evaporation surface. Vortical tube are provided with twisting device in the form of screw with double rectangular thread and conical narrowing of screw passage for feeding petroleum by two thin flows tangentially to inside surface of vortical tube. EFFECT: simplified process enabling its application directly under oil-field conditions. 2 dwg

Description

 The invention relates to the refining industry, in particular to primary methods of oil refining with its separation into fractions, i.e. distillation.
 The basis of industrial methods for the distillation of oil is its heating to a temperature that allows you to gradually drive away from the lightest to heaviest fractions. The resulting vapor and liquid phases are subjected to rectification in columns (I. L. Gurevich, "Oil and Gas Processing Technologies", part 1, M., Chemistry, 1972, p. 202-203).
 Known methods are complex and time-consuming, requiring special equipment operating in the factory.
 Known distillation of oil with a single evaporation (ibid., Pp. 199-202), which is simpler to implement, requires less heat. Its disadvantage is the poor clarity of the separation of oil into fractions, the low efficiency of the process.
 Closest to the proposed one is a method of oil refining (1372922, IPC C 10 G 7/00, publ. 02/20/2000) by heating and separating it in a fractionating column to obtain stable oil and low boiling fractions, then compressing these fractions, removing steam phase and condensing it to produce gas and condensate containing a wide fraction of light hydrocarbons.
 The known method is complex and expensive.
 The objective of the invention is to simplify the method of obtaining fractions of light hydrocarbons with its implementation directly in oil fields using commercial oil.
The problem is achieved by a method of producing light hydrocarbon fractions from oil, including heating the original oil, its separation into the residual fraction and the vapor phase, the discharge of the latter with subsequent condensation and collection of the oil product, in which, unlike the prototype, the initial oil is heated to a temperature of 80-140 o C and the separation of oil into fractions is carried out by obtaining a highly developed evaporation surface in the form of a thin swirling film of oil and subsequent intensive evaporation with additional heating over evaporation.
 The highly developed evaporation surface is provided by a vortex film evaporator, which is a vertical cylindrical casing with tubes placed in it, on the inner walls of which they form high-speed film evaporation surfaces by means of a swirling supply of jets of hot oil.
 Film heat exchangers (a.s. USSR 1615528, IPC F 28 D 3/04, publ. 23.12.90) were constructed according to a similar principle, which, however, are not used to obtain light hydrocarbon fractions from oil due to the impossibility of their clear separation from the mass hot mix. Only in the proposed set of essential features is it possible to achieve the specified technical result.
 The essence of the proposed method is illustrated by drawings.
 Figure 1 presents a schematic diagram of an installation for producing light hydrocarbon fractions from oil; figure 2 presents a vortex film evaporator.
 The installation (Fig. 1) contains a heat exchanger 1, a vortex film evaporator 2, a heating furnace 3, an air condenser 4, storage tanks 5 and 6, pumps 7 and 8.
 The vortex film evaporator (Fig. 2) consists of a cylindrical casing 9, in which vortex tubes 11 are placed between two tube sheets 10. At the top of each vortex tube there is a twisting device 12 made in the form of a screw with a double-entry rectangular thread and a tapered narrowing of the helical channel for supplying oil with two thin jets tangentially to the inner surface of the vortex tube and the formation of a thin swirling film of oil on it. A hole is made in the center of the screw twisting device, which communicates via a lead-out tube 13 with a steam chamber 14 having a fitting 15 for the exit of light fraction vapors. In the lower part of the casing there is a fitting 16 for outputting the residual oil fraction. For additional heating of the evaporation surface of the vortex tubes, there are provided nozzles for inputting 17 and outputting 18 water vapor into the annulus 19 of the vortex film evaporator. Hot oil is fed to the vortex film evaporator through the pipe 20 for evaporation.
 The method is as follows.
 Field oil pump 7 serves for pre-heating in the heat exchanger 1, followed by feeding into the heating furnace 3 to heat to the temperature of evaporation of light fractions.
 From the furnace, hot oil enters the vortex film evaporator 2, where through screw twists 12 moves at high speed along the inner surface of the vortex tubes 11, forming a highly developed film evaporation surface and, accordingly, a vapor-liquid stream of boiling oil. After the installation enters into technological mode, the heat exchanger 1 operates from the heat of the spent (residual) oil coming from the vortex film evaporator through the fitting 16.
 Vapors of light hydrocarbons through the outlet tubes 13 of the vortex film evaporator 2 are sent to the steam chamber 14 and then through the fitting 15 into the air condenser 4 of the installation. The condensation product is collected in the storage tank 5. Non-condensed gas is sent to the burners of the furnace 3.
 At the initial stage of the installation, gas is supplied to the furnace burners from the main pipeline II.
 The spent hot oil from the vortex film evaporator, having given off heat in the heat exchanger 1, is collected in the tank 6 and, as accumulated by the pump 8, is pumped out to the fleet along line III.
 Thus, the proposed invention allows the most efficient implementation of obtaining fractions of light hydrocarbons from oil, reducing hardware costs, energy intensity, providing the possibility of implementing the method directly in oil fields using field oil.
