    (54) DEVICE FOR
    The device allows continuous sampling of a certain fraction of crude oil from a column for distillation of oil under atmospheric pressure, in particular in the zone where this oil injected into the column at appropriate pressure and temperature undergoes a sharp expansion with evaporation of most of it, at the remaining liquid fraction or residue is recovered at the bottom of THIS COLUMN;
    A device for sampling, consisting of a distillation column, from a sampling device, connected in series with a capacitor, filter and analyzer [1].
    The disadvantage of this device is the inaccurate control of the evaporated fraction.
    The purpose of the invention is to eliminate this drawback.
    This goal is achieved through implementation. a sampling device in the form of a tube equipped with means for limiting the speed of vapors, and means for limiting the speed of vapors is a tip mounted on the open end of the tube and contains
    SAMPLING FROM A RECTIFICATION COLUMN A casing, on the bottoms of which a series of coaxial rings overlapping each other is installed.
    In FIG. 1 shows a diagram of a device; in j of FIG. 2 - sampling tube; in FIG. 3 - cross section of the tip; in FIG. 4 additional equipment.
    The device consists of a column for distillation of crude oil at atmospheric pressure 1, an inlet pipe 2 connected to zone 3, and a continuous sampling circuit 4.
    This circuit mainly comprises a primary circuit consisting of a sampling tube 5 that extends laterally into the column, and this tube is equipped with a tip 6 with a flange 7, a shut-off valve 8, a pipe 9, which is connected through a valve 10 to a condenser 11 with a coil 12 and a housing 13 and pipelines 14 and 15. The continuation of the coil is a pipe 16 having a safety device 17 connected to an electric valve 18 and a shut-off valve 19 with a filter 20, a valve 21, a pipe 22, a pump 23, a pipe 24, a pump 23 and a flow rum 25. an adjustment valve 26 and a filter 20 connected by a pipe to the pump 28 and a supply analyzer 29 with a valve 30.
    The sampling tube is made with an adapter sleeve 31 and ends with a shoulder 32, on which a mounting flange 33 is fixed, which, in turn, is fixed on the back of the zone 34 of the tube 5 with welds 35. The centering of the tube 5 in the sleeve 31 is provided by transverse legs 36, abutting against the inner wall of the coupling, while part 34 is extended into the column 1 by an inclined part 37 directed to the bottom of the column j and ending with a flange 38, which allows the tube to be fixed using a tie 39 suspended from the structure 40, details the implementation of which are not significant for the invention. The flange 38 also allows you to connect the tube with a curved tip 41 having an open end 42 facing the bottom of the column, through which the trapped pairs fall into the tube 5, and then move to its end.
    The means for restricting the vapor velocity consists of an element 43 for connecting the tube 44, continued by the casing 45. This last one consists of two parallel bottoms 46 and 47, with the tube 44 passing through the bottom 46. Coaxial rings' 48, 49 and 50 are located between the two bottoms forming a series of labyrinths inside the casing 45 to limit the speed of the vapors entering the casing through the side openings 51 and 52 facing the bottom of the column, and these labyrinths also prevent the dropping of droplets of liquid residue that did not evaporate in the zone
    3. It is advisable to make a hole 52 in the bottom 47 of the casing 45, to which a bent pipe 6 is connected, forming a drain siphon, the lower open end of which 53 allows the casing to be continuously released from the liquid fraction, which can be drawn in by pairs. Alternatively, the casing 45 can be filled with a metal or other swab, facilitating the capture of liquid.
    The device operates as follows.
    To ensure sampling of a part of the oil evaporated in this way, a continuous sampling circuit 4 is used in zone 3. The pairs captured by the tube 5 move along it in the direction of arrow 7 and, after passing through the shut-off valve 8, are collected in the pipe 9. This last one is connected through a valve 10 with a condenser 11, containing mainly a coil 12, in which the vapors coming from the pipe 9 condense due to the circulation in the outer casing 13 of the cooling agent supplied to the condenser through the pipe 14 and output through the pipe 15. On
    786934 4 the condenser 11 output, the flow rate of which in practice is about 120 150 l / h, enters the pipe 16, equipped with a safety device 17, which actuates the electric valve 18 when the condensate temperature exceeds a predetermined threshold, which may occur, for example, due to a malfunction of the condenser .
    The pipe 16 also contains a shut-off valve near the filter 20. Upon exiting this filter, condensate, passing through another shut-off valve 21, enters the pipe 22 connected to the circulation pump 23, which pumps the condensate into the pipe 24, which, in turn, is connected with the column 1 at a point located in the expansion zone 3 under the pipeline 2, as a result of which the selected part is almost completely and continuously returned to the column. Adjusting valve 26 allows you to control the performance of the circulation pump 23 ,. measured by a flow meter 25.
    A part of the condensate circulating in this way in the primary circuit of circuit 4 is preferably discharged, at the level of the filter 20, to a pipe 27 and a pump 28 supplying the analyzer 29. The valve 30 controls the analyzer's power consumption.
    As can be seen from this figure, the expansion zone 3 is limited, in particular, in its upper part, by a first horizontal distillation plate 54, which, in turn, is bounded laterally by the wall 55, over which the unselected liquid fraction condensing on this plate is drained. This liquid fraction is collected in column 1 in a side tank 56, attached to the inner wall of the column, after passing through a drain trough 57, which acts as a level damper in the tank 56. The position of this level is measured using a sensor 58 or other such device acting on regulator 59. The liquid is taken from the reservoir 56 through a pipeline 60 connected to a circulation pump 61, forcing into the pipe 62, returning the liquid to the column, while the performance is the first pump as measured by the flow meter 63, controlled by a controller 59 so that the level in the tank 56 was kept constant. Due to this scheme, the flow rate of the liquid returned to the column exactly corresponds to the flow rate of the liquid continuously draining from the plate 54. Knowing this flow rate, the costs of selecting various distillation products in the column and the flow rate of crude oil at the inlet, it is possible to draw up a quantitative balance and, in particular, determine the number of vaporized parts in one of two expressions:
    D B + BR + DS DB (2) in which:
    D sn - the consumption of the selection of the product of distillation ·· η-th order;
    Dg is the flow rate of the return liquid stream, measured in the manner indicated above;
    Djj - consumption of processed crude oil; Ots is the flow rate of the liquid residue.
    Thus, a device was obtained for continuous sampling, in particular, from a column for distillation of crude: oil under atmospheric pressure, which has the advantage that it allows you to directly power the chromatographic analyzer, with the help of which data are obtained that allow you to quickly build a distillation curve of the processed oil, while the selected fraction gives a complete picture of this oil, with the exception of the liquid part or residue, which cannot be analyzed by a chromatographic device, as well as the floor chat information on the percentage of the fraction in the total sample. A curve built on the basis of these data can be directly graded in the output values, first only for the selected fraction, and then extrapolated to the liquid residue, while the final curve is a characteristic of the entire sample.
    $ Of course, the invention is not limited to an example of execution, which was described in more detail and depicted in the figures, but on the contrary, covers all options.

    Claims (2)
    [1]
    a valve 26 and a filter 20 connected by a pipe 27 to a pump 28 and a feed analyzer 29 to a valve 30. The sampling tube is made with a transition sleeve 31 and ends with a shoulder 32 on which the mounting flange 33 is fixed, which in turn is fixed to the rear part of the zone 34 of the tube 5 by means of welds 35. The centering of the tube 5 in the coupling 31 is provided by transverse tabs 36 abutting the inner wall of the coupling, while part 34 is continued inside the column by the inclined part 37 directed to the bottom of the column and ending with a flange 38, which allow the tube to be secured by stretching 39, under the design 40, the details of which are not essential to the invention. The flange 38 also allows the tube to be connected to the bent tip 41, having an open end 42, facing the column bottom TO, through which the entrained vapors fall into the tube 5, and then move to its end. The dp rate-limiting device dp consists of an infill 43 for connecting the tube 44, continued by the casing 45. This latter consists of two parallel bottoms 46 and 47, with the tube 44 passing through the bottom 46. Between the two bottoms are coaxial rings 48, 49 and 50 Inside the casing, 45 rows of labyrinths dp limit the velocity of the vapor entering the casing through the side openings 51 and 52 facing the bottom of the column, and these labyrinths also prevent the liquid residue that is not evaporating in zone 3 from entering the tube. Cele accordingly, in the bottom 47 of the housing 45, an opening 52 is connected to which the bent pipe 6 is connected, forming a drain siphon, the lower open end 53 of which allows the housing to be continuously released from the liquid fraction, which can be pulled in pairs. Alternatively, the housing 45 may be filled with a metal or hydraulic swab to facilitate trapping of the liquid. The device operates as follows. DP to ensure sampling of a part of oil evaporated in this manner, in zone 3, use continuous sampling circuit 4. Couples caught by tube 5 move along it in the direction of arrow 7 and after passing through the check valve 8 are collected in pipe 9 This latter is connected via a valve 10 to a condenser 11 containing mainly a coil 12 in which the vapors coming from the pipe 9 are condensed by circulating in the outer casing 13 a cooling agent supplied to the condenser through line 1 4 and discharged through line 15. At the outlet of condenser 11, condensate, the expense of which is about 120150 l / h in practice, enters the pipe 16, equipped with a safety device 17, which actuates the electric valve 18 when the condensate temperature exceeds a predetermined threshold, which may occur, for example, due to a faulty capacitor. The pipe 16 also contains a shut-off valve 19 near the filter 20. On leaving this filter, condensate, passing through another shut-off valve 21, enters the pipe 22 connected to the circulation pump 23, which pumps the condensate into the pipe 24, which, in its the queue is connected to column 1 at a point located in the expansion zone 3 under pipeline 2, with the result that the part to be withdrawn almost completely and continuously returns to the column. An adjustment valve 26 allows control of the performance of the shredding pump 23 ,. measured by the flow meter 25. A part of the condensate circulating in the primary circuit of circuit 4 is thus diverted, preferably at the level of the filter 20, to the pipe 27 and the pump 28, the supply analyzer 29. The valve 30 controls the flow of the analyzer. As can be seen from this figure, the expansion zone 3 is limited, in particular, in its upper part, by the first horizontal distillation plate 54, which, in turn, is bounded laterally by the wall 55, over which merging of the unseparated liquid fraction that condenses on this plate occurs. This liquid fraction is collected in column 1 in the side tank 56 attached to the inner wall of the column, after passing through the drain chute 57, which acts as a level dampener in tank 56. The position of this level is measured using sensor 58 or another device of this kind acting to the regulator 59. The liquid is taken from the reservoir 56 through the pipeline 60 connected to the circulation pump 61, which carries out the injection into the pipeline 62, which returns the liquid to the column, while the flow rate is In addition, the pump measured by the flow meter 63 is controlled by the controller 59 so that in the tank 56 the level is kept constant. Thanks to such a scheme, the flow rate of the fluid returned to the column corresponds exactly to the flow rate of the fluid continuously flowing from the plate 54. By knowing this flow rate, the cost of collecting various distillation products in the column and the flow rate of crude oil at the inlet, you can make a quantitative balance the amount of evaporated part of one of two expressions: BB in which: consumption of the distillation product selection of the n-th order; reverse liquid flow rate measured as above; the processed crude oil consumption is the liquid residue consumption. Thus, a device for continuous sampling, in particular, from a crude distillation column, is obtained; oil at atmospheric pressure, which has the advantage of allowing it to directly feed a chromatographic analyzer, by means of which data is obtained that allows you to quickly build a curve of processed oil, while taking a fraction gives a complete picture of this oil, with the exception of the liquid part or a residue that cannot be analyzed by a chromatographic instrument, as well as to obtain α-percentage of this fraction in the total composition of the sample. The curve constructed on the basis of these data can be directly calibrated in terms of yields, first only for the selected fraction, and then extrapolated to a liquid residue, with the final curve being a characteristic of the entire sample. Of course, the invention is not limited to the example of implementation that has been described in more detail and is depicted in the figures, but, on the contrary, covers all variants. Claim 1: A sampling device from a distillation column consisting of a sampling device connected in series with a condenser, a filter and an analyzer, characterized in that, for the purpose of precise control of the evaporated fraction, the sampling device is in tube-shaped form and equipped with a q q ratio for limiting vapor velocity.
