    The invention relates to methods for producing stable emulsions of a finely dispersed medium in hydrocarbons and can be used to obtain sulfur emulsions in asphalt, bitumen, good 5 role and similar hydrocarbons.
    The closest to the proposed method is an emulsion of sulfur in the hydrocarbon type of bitumen and asphalt by feeding a mixing zone a mixture of sulfur and 0 hydrocarbon, heating the mixture, stirring the mixture to obtain an emulsion and cooling the emulsion [1].
    The disadvantage of this method is the impossibility of obtaining emulsions with ton- 15 dispersed sulfur with a particle size of less than 10 microns.
    The purpose of the invention is the provision of the possibility of obtaining an emulsion with a particle size of sulfur of not more than 10 microns. 20
    The circuit is achieved in that according to the method for producing an emulsion of sulfur in a hydrocarbon, mainly bitumen and asphalt, by feeding from 15 to 100 parts by weight to the mixing zone sulfur and 100 parts by weight hydrocarbon at 125-200 ^ 0 / mixing the mixture to obtain an emulsion and cooling the emulsion, mixing the mixture is carried out in a film with a thickness of 0.1-2.25 mm while subjecting the film to centrifugal force and compression.
    The mixture is supplied at 140 160 ° C. The impact of centrifugal force is carried out by rotating the film at a speed of 3000-7400 rpm
    To obtain an emulsion of sulfur in coal. / Hydrogen material like asphalt, bitumen, etc., a mixture of molten sulfur and a hydrocarbon substance is dispersed with vigorous stirring. In order for sulfur to become liquid, it is treated at temperatures above 120 ° C, but the upper temperature limit depends on the nature of the hydrocarbon substance and on the temperature at which liquid sulfur becomes viscous. In the practical application of dispersed sulfur in bioptim3 for road surfaces, the emulsion is prepared at 125-200 ° C, the average preferred 130-170 ° C or 150-160 ° C.
    To achieve a high degree of dispersion, devices adapted for emulsification of liquids are used. The sulfur emulsion in bitumen is formed by passing a sulfur-bitumen mixture in a turbine, the gap of which is 0.1 to 2.25 mm and, especially, 1.15 mm.
    In addition, in order to obtain a good result, the size of the gap should be regulated depending on the proportion of sulfur with respect to bitumen.
    The larger the gap is chosen, the higher the proportion of dispersible sulfur. It is necessary to adjust the speed of rotation of the turbine and the size of the gap, so that the compression in the gap does not reach the one at which sulfur turns into sulfur / L. For smaller gaps, lower speeds and vice versa are needed.
    Using a Moritz turbine of the BF 50 V type with an adjustable gap and a rotor speed of 7400 rpm, very stable emulsions from 13 to 25 hours of sulfur per 100 were obtained. including bitumen (penetration 80-100), with a gap of 0.3 to 0.5 mm.
    A sulfur-bitumen mixture is prepared in a device producing high dispersion, such as in a turbo emulsifier, and the emulsion thus obtained is processed in a turbine with an appropriately adjusted gap, which facilitates the operation of the turbine. It is possible to pass the emulsion several times through a’’ turbine to obtain a high degree of dispersion, i.e. desired smallest sizes of sulfur droplets. For this, the proposed
    936794. 4, the method can be carried out with the help of several turbines or turbines and turbo emulsifiers installed in series.
    ; In the proposed method, a Moritz turbine, type BV 50 V, is used, with re adjustable by a gap of 3 p capacity, driven by a 1.75 Che motor. The rotor speed is regulated I from 7000 to 3000 rpm. Bitumen and sulfur, in the desired proportion, are introduced simultaneously into a rotating turbine. The temperature at the inlet to the turbine is from 140 to 190 C, and at the outlet 110-140 C, the average temperature between the temperature at the inlet and at the outlet is considered the processing temperature defined above. The effluent product again returned to the turbine to undergo its emupgirova (NIJ for 3 min.
    In other examples, a mixture of sulfur and bitumen, previously emulsified in a Moritz turbo-emulsifier for 3 minutes, is introduced into the above turbine; In this case, there is no return in the loop. In the BF 50 V turbine, the mixture is processed only once.

    Example 1. Prepare a series. samples of sulfur emulsions (from 1 to 4) in bitumen with a penetration of 80 - 100 in the Moritz turbine described above, with a gap of 0.56 mm at 160 and 120 ° C.
    Pure bitumen is passed through a turbine under the same conditions. Measure the viscosity of the products obtained, as well as the control mixture (5), prepared by simple stirring of 33.3 hours, molten sulfur with 100 parts of the same bitumen at temperatures from 120 to 166¾. The results, namely, the logarithms of viscosities are given in table. 1.

    In this case, the viscosity of emulsions, according to experiments 1 to 4, varies much more, depending on temperature, than the viscosity of bitumen or a heterogeneous mixture of bitumen-sulfur. For emulsions in experiments 2 to 4 i.e. above 11 parts sulfur per 100 parts of bitumen, the composition is much harder in the cold state (viscosity at 80 ° C is much higher) than the mixture (5) or pure bitumen (6). On the contrary, at high temperatures, in particular about 160 ° C, at which work with bituminous compositions is carried out, the viscosity of emulsions 1 through 4 is much lower than the viscosity of a mixture of pure bitumen. The result is greater ease of processing in the hot state - with better stability in the cold.

    The invention relates to methods for producing stable emulsions of a meccodispersed medium in hydrocarbons and can be used to produce sulfur emulsions in asphalt, batum, tar and similar hydrocarbons.
    Closest to the present invention is a method for producing an emulsion of sulfur in a hydrocarbon such as bitumen and asphalt by feeding a mixture of sulfur into a hydrocarbon into the mixing zone, heating the mixture, mixing the mixture to obtain an emulsion, and cooling the emulsion ij.
    The disadvantage of this method is the impossibility of obtaining emulsions with finely dispersed sulfur with a particle size of less than 1O micron.
    The circuit of the invention is to provide the possibility of obtaining an emulsion with a particle size of sulfur of no more than 10 microns.
    The goal is achieved by the fact that according to the method of obtaining the emulsion of sulfur in the hydrocarbon, mainly bitumen and asphalt, by feeding into the zone
    mixing from 15 to 100 weight.h. sulfur in 1OO weight.h. hydrocarbons at 125–200 ° C, mixing the mixture until the emulsion is obtained and the emulsion is cooled, the mixture is stirred in a thick OD-2.25 mm film while simultaneously acting on the film by centrifugal compression and compression.
    The mixture is fed at 14O-. The impact of the centrifugal seeps is carried out by rotating the film at a speed of ZOOO-7400 rpm. To obtain a sulfur emulsion in coal / hydrogen material such as asphalt, vacuum, etc., the mixture of molten sulfur and the hydrocarbon substance is subjected to dispersion with vigorous stirring. In order for the sulfur to become liquid, the treatment is carried out at temperatures above 12 ° C, but the upper limit of the temperature depends on the nature of the hydrocarbon substance and on the temperature at which the liquid sulfur becomes viscous. In practical use of dispersed sulfur in bitumen for pavements, the emulsion is prepared at 125-2 ° C, averagely preferred at 130-170 ° C or 15O-160 ° C. serotum in the turbine, the gap of which lies in the range of about Oji up to 2.25 mm and, especially, from 0.4 to 1.15 mm. In addition, in order to obtain the optimum result, the size of the gap must be adjusted depending on the sulfur propiona in relation to the bitumen. Those who choose zvasr are chosen the higher the proportion of sulfur being dispersed. It is necessary {to adjust the rotational speed of the turbine and the size of the gap so that the compression in the gap does not reach that at which sulfur is converted to sulfur. For small gaps, smaller speeds are needed and vice versa. In the case of Morita-type turbofans of the type BF VO B with an adjustable gap and with a rotor speed of 74OO rpm, very stable ecls from 13 to 25 hours of sulfur on the SO.h. The first one (penetration 80-10 O), with a gap of 1 from 0.3 to; 0, S MM, Osiecb is prepared sulfur-bitumen in the device, which produces a high dispersion, such as, for example, a chrombo-emulsifier, and thus received an emulsion It is bathed in a turbine with a correspondingly adjusted clearance, which facilitates the operation of the turbine. You can also skip the turbine several times through the turbine to obtain a high degree of dispersion, i.e. desired smallest sizes of sulfur droplets. For this, the proposed method can be carried out with the help of several turbines or turbines and turbo-emulsifiers sequentially installed. The proposed method uses a Moritz-type turbine, type BV 50 V, with re, driven by a gap, with a capacity of 1.75 l .with. The rotor speed is adjustable from 7OOO to ZOOO rpm. Bitumen and sulfur, in the desired proportion, are introduced simultaneously into a rotating turbine. The turbine inlet temperature is from 140 to 19 ° C, and at the output of 11 ° -14 ° C, the average temperature, between the temperature at the entrance and at the output, is considered the treatment temperature k, defined above. The effluent is returned to the turbine again to emulsify for 3 minutes. In other examples, a mixture of sulfur and bitumen, previously emulsified in a Moritz turbo-emulsifier, is introduced into the above turbine for 3 minutes, in which case there is no return in the cycle. In the BF 50 V turbine, the mixture is processed only once. Example 1. A series of samples of sulfur emulsions (from 1 to 4) was prepared in bitumen with 80 - 1OO foam in the Moritz turbine, described above, with a gap of 0.56 mm at 160 and. Pure bitumen is passed through the turbine for those. same conditions. Measurements of the viscosity of the products obtained, as well as the control mixture (5) prepared by simply moving 33.3 hours, molten sulfur from 1OO of the same bitumen at temperatures from 120 to 16ClPCJ, are carried out. The results, namely, the logarithms of viscosities are given in Table . 1. Table 1

    2.33 In this case, the viscosity of the emulsions, according to experiments 1 to 4, varies much more, depending on the temperature, than the viscosities of bitumen and pi heterogeneous mixture of bitumen-sulfur. For emutations in experiments 2 to 4, i.e. above 11 hours of sulfur per 100 hours, bitumen, the composition is much more rigid in the cold state (viscosity at much higher) than the mixture (5). or pure bitumen (6). On the contrary, at high temperatures, in particular about 16 ° C, at which the viscosity of the bitumen compositions is carried out, the viscosity of emulsions from 1 to 4 is much lower than the viscosity of the mixture of pure bitumen. As a result, greater ease of processing in a hot condition and with better stability in a cold one is absorbed. For products similar to test 1, but processed first for 3 minutes in a Moritz turbo-emulsifier, and then in a BF 50 V turbine, the results are the same as in the table. 1, with an even more emphasized difference between 80 and 160 ° C for emulsions.
