The following petroleum sulfonate preparation method is carried out by using the petroleum sulfonate preparation device.
As shown in fig. 1, the petroleum sulfonate production apparatus includes a supergravity sulfonation reactor 10, a supergravity aging neutralization hydrolysis integrated reactor 20, a second line 40, a third line 50, and a fourth line 60. The hypergravity sulfonation reactor 10 is in communication with the hypergravity aging neutralization hydrolysis integrated reactor 20 through a first line 30. The second line 40 is in communication with the hypergravity aging, neutralization and hydrolysis integrated reactor 20 for adding liquid caustic to the hypergravity aging, neutralization and hydrolysis integrated reactor 20. The third line 50 communicates with the discharge port of the supergravity aging neutralization hydrolysis reactor 20.

The petroleum sulfonate preparing apparatus includes a supergravity sulfonation reactor 10, a supergravity aging neutralization hydrolysis integral reactor 20, a second pipeline 40, a third pipeline 50 and a fourth pipeline 60, wherein the supergravity sulfonation reactor 10 is communicated with the supergravity aging neutralization hydrolysis integral reactor 20 through a first pipeline 30, the second pipeline 40 is communicated with the supergravity aging neutralization hydrolysis integral reactor 20 for adding liquid alkali into the supergravity aging neutralization hydrolysis integral reactor 20, the third pipeline 50 is communicated with a discharge port of the supergravity aging neutralization hydrolysis integral reactor 20, the fourth pipeline 60 is respectively communicated with the supergravity aging neutralization hydrolysis integral reactor 20 and the third pipeline 50, so that part of petroleum sulfonate flowing out from the discharge port of the supergravity aging neutralization hydrolysis integral reactor 20 flows back to the supergravity aging neutralization hydrolysis integral reactor 20, the outlet of the second pipeline 40, the outlet of the fourth pipeline 60 and the outlet of the first pipeline 30 are all positioned in the supergravity aging, neutralization and hydrolysis integrated reactor 20 and are sequentially far away from the bottom of the supergravity aging, neutralization and hydrolysis integrated reactor 20 along the height direction of the supergravity aging, neutralization and hydrolysis integrated reactor 20, the aging, neutralization and hydrolysis steps are concentrated in one component by arranging the supergravity aging, neutralization and hydrolysis integrated reactor 20, the probability of pipeline blockage and equipment corrosion is reduced, the material fluidity is improved, the equipment shutdown times are reduced, the preparation efficiency of petroleum sulfonate is improved, raw oil can be quickly mixed and updated on the mass transfer surface in the supergravity aging, the huge shearing force is obtained, the huge interphase updating speed is generated, the interphase mass transfer rate is greatly improved, the active matter content of the product is increased.
In this example, the arrows in fig. 1 indicate the flow direction of the reaction mass.
In this embodiment, the raw oil enters the hypergravity sulfonation reactor 10 to carry out sulfonation reaction, and the sulfonic acid generated by the sulfonation reaction and the raw oil which is not sulfonated enter the hypergravity aging neutralization hydrolysis integrated reactor 20 through the first pipeline 30. Specifically, the hypergravity sulfonation reactor 10 is disposed above the hypergravity aging and hydrolysis integrated reactor 20, and the sulfonic acid and the unsulfonated raw oil generated by the sulfonation reaction enter the hypergravity aging and hydrolysis integrated reactor 20 under the action of gravity.
Since the outlet of the second pipeline 40, the outlet of the fourth pipeline 60 and the outlet of the first pipeline 30 are all located in the supergravity aging and hydrolysis integrated reactor 20 and are sequentially located away from the bottom of the supergravity aging and hydrolysis integrated reactor 20 along the height direction of the supergravity aging and hydrolysis integrated reactor 20, layering of materials in the supergravity aging and hydrolysis integrated reactor 20 occurs. Specifically, the sulfonic acid with a relatively high specific gravity falls to the lower part of the reactor 20 to perform neutralization reaction with the liquid alkali, and the petroleum sulfonate which flows back to the reactor 20 after neutralization is also present at the lower part, so as to adjust the strength of the neutralization reaction. The unsulfonated raw oil floats on the upper part of the supergravity aging neutralization hydrolysis integrated reactor 20 and plays a role of liquid seal, so that high-temperature water vapor generated by the neutralization reaction is prevented from flowing into the supergravity sulfonation reactor 10.
As shown in fig. 1, the petroleum sulfonate preparing apparatus further includes a circulation pump 70 and a discharge pump 80. A circulation pump 70 is provided on the third line 50. The discharge pump 80 is disposed on the third line 50 and is disposed away from the circulation pump 70 with respect to the discharge port of the supergravity aging and hydrolysis integrated reactor 20, and the connection point of the fourth line 60 and the third line 50 is located between the circulation pump 70 and the discharge pump 80. By providing the circulation pump 70 and the discharge pump 80, power is provided for the return of a portion of the petroleum sulfonate to the supergravity aging neutralization hydrolysis integrated reactor 20 and for the discharge of petroleum sulfonate products.
In the present embodiment, the flow rate of the circulation pump 70 is greater than the flow rate of the discharge pump 80. Thus, due to the restriction of the flow rate, the petroleum sulfonate discharged from the circulation pump 70 flows not only to the discharge pump 80 but also to the supergravity aging and hydrolysis integrated reactor 20 through the fourth line.
In the present embodiment, the connection point of the fourth line 60 and the third line 50 is disposed close to the circulation pump 70 with respect to the discharge pump 80. Further, the length of the fourth line 60 is less than the distance between the junction of the fourth line 60 and the third line 50 to the discharge pump 80. This results in a fourth line 60 having a lower resistance than the connection point between the fourth line 60 and the third line 50 to the discharge pump 80, and the petroleum sulfonate flowing from the circulation pump 70 can more easily flow to the fourth line 60, so that most of the petroleum sulfonate can flow back to the supergravity aging neutralization hydrolysis reactor 20 to form a circulation, thereby better controlling the neutralization reaction in the supergravity aging neutralization hydrolysis reactor 20 and increasing the active material content of the product.
As shown in fig. 1, the petroleum sulfonate production apparatus further includes a flow regulating valve 90, the flow regulating valve 90 being disposed on the fourth line 60. By providing the flow rate adjusting valve 90, the flow rate of the petroleum sulfonate flowing back to the supergravity aging and hydrolysis integrated reactor 20 can be adjusted according to the reaction conditions, thereby better controlling the reaction in the supergravity aging and hydrolysis integrated reactor 20.
In this embodiment, flow meters are provided on both the fourth line 60 and the third line 50 to monitor the flow of petroleum sulfonate in each line.
As shown in fig. 2 to 3, the supergravity aging neutralization hydrolysis integrated reactor 20 includes a rotor 21 and a distributor 22. The rotor 21 has a cylindrical structure, and the outlet of the fourth pipeline 60 and the outlet of the first pipeline 30 are both positioned in the rotor 21. The distributor 22 includes a distributing ring 221 and a plurality of discharging pipes 222, the distributing ring 221 is disposed above the rotor 21 and is communicated with the second pipeline 40, the plurality of discharging pipes 222 are all communicated with the distributing ring 221 and are disposed at intervals along the circumference of the distributing ring 221, the plurality of discharging pipes 222 are all extended into the rotor 21, and the outlet of the discharging pipe 222 is used as the outlet of the second pipeline 40.
Specifically, the caustic soda liquid enters the distribution ring 221 through the second pipeline 40 under the action of external power equipment, is sprayed on the rotor 21 through a plurality of discharge pipes 222, and is subjected to neutralization reaction with sulfonic acid. The reaction raw materials are rapidly mixed and the mass transfer surface is updated through the division of the rotor 21 under the action of the supergravity. The two-phase fluid is contacted in the porous medium or the pore canal, the shearing force is hundreds or thousands of times of the conventional gravity field, the liquid is torn into a liquid film, liquid drops and liquid filaments with micron or nanometer level by the huge shearing force, the huge phase-to-phase update speed is generated, and the inter-phase mass transfer rate is improved by 1 to 3 orders of magnitude compared with a common tower, so that the mass transfer and the mixing are greatly enhanced, and the active matter content of the product is increased.
In the present embodiment, the number of the discharge pipes 222 is three, and the three discharge pipes 222 are disposed at equal intervals along the circumferential direction of the distribution ring 221. The equally spaced arrangement allows the caustic soda liquid to be sprayed evenly on the rotor 21 to be mixed evenly with the sulphonic acid to increase the rate of neutralisation.
In the present embodiment, the surface of the rotor 21 is coated with a tantalum metal layer. The tantalum metal has extremely high corrosion resistance, does not participate in aging reaction, neutralization reaction and hydrolysis reaction, and ensures the progress of chemical reaction in the rotor 21. Of course, the surface of the rotor 21 may be coated with other types of corrosion resistant material layers, which may be selected according to practical requirements.
As shown in fig. 1, the petroleum sulfonate preparing apparatus further includes a cooling assembly 100, and the cooling assembly 100 is connected to the supergravity aging and hydrolysis integrated reactor 20. Specifically, the outer part of the hypergravity aging neutralization hydrolysis integrated reactor 20 is provided with a jacket, the cooling component 100 is communicated with the jacket, and circulating cooling water with a certain temperature is introduced into the jacket, so that chemical reaction heat in the hypergravity aging neutralization hydrolysis integrated reactor 20 is taken away, the viscosity of reaction materials is controlled to have a certain fluidity, and the normal operation of chemical reaction is ensured.
