Description

Technical Field

[0001] The invention relates to the technical field of natural gas hydrates, in particular to a device for testing the adhesion of hydrate particles. Background Art

[0002] Natural gas hydrates generally refer to non-stoichiometric clathrate complexes formed by the main components of natural gas (such as CH4, C2H6) and water under high pressure and low temperature conditions. During the process of hydrate resource extraction and oil and gas transportation, the components of the fluid in the pipeline include natural gas and water. Under this flow state, due to the low temperature and high pressure conditions in the pipeline, tiny bubbles in the liquid phase and condensed water droplets in the gas phase may form hydrate particles. Hydrate particles will aggregate and adhere to the pipe wall during the flow of the fluid, eventually blocking the pipeline, causing local pressure increase, reduced extraction efficiency and potential safety problems. The typical hydrate blockage formation process in the pipeline consists of the following four stages: (1) Suspension of bubbles in the liquid phase and condensation of droplets on the pipe wall; (2) Nucleation and growth of hydrate particles in the liquid phase and on the wall; (3) Aggregation and deposition of hydrate particles during flow; (4) Gradual increase in sediment volume, eventually blocking the pipeline. In the above process, the fundamental reason for the aggregation and deposition of hydrates is the adhesion between hydrate particles and between hydrate particles and the pipeline wall. By measuring the adhesion between multiple hydrate particles, the deposition of hydrates can be better prevented, providing safety protection for pipeline transportation of natural gas.

[0003] Since hydrate particles take a long time to form, traditional hydrate particle adhesion test devices can only generate one type of hydrate particles at a time and are unable to measure the shear stress of hydrate particles and the adhesion between hydrate particles and the wall. At the same time, manual dripping is required during the experiment. Summary of the Invention

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] like Figure 1 A hydrate particle adhesion test device shown includes a test system, a liquid supply system and a wastewater recovery system.

[0028] The testing system comprises a reactor 1, a detachable glass cover 28 sealedly mounted on the top surface of the reactor 1, and a high-definition microscope 2 positioned above the glass cover 28 for observing the morphology of hydrate formation in the reactor through the glass cover 28. The high-definition microscope 2 is movable up and down by a fixed pulley 3. The signal of the high-definition microscope 2 is connected to a computer 4, and the testing process can be controlled by the computer 4.

[0029] The reactor 1 has four reaction chambers 5 sealed and separated by movable vacuum glass panels. Specifically, the vacuum glass panels include a vertical vacuum glass panel 6 and two horizontal vacuum glass panels 7. The vertical vacuum glass panel 6 is located at the vertical center of the reactor 1. Its vertical movement divides the reactor 1 into two left and right cavities; the two horizontal vacuum glass panels 7 are respectively located on the left and right sides of the vertical vacuum glass panel 6. After the two horizontal vacuum glass panels 7 are moved horizontally, the interior of the reactor 1 can be divided into four reaction chambers 5.

[0030] The upper and lower ends of the vertical vacuum glass panel 6 are sealed with the upper and lower ends of the reactor 1 by sealing rubber blocks. Sealing rubber blocks for sealing the horizontal vacuum glass panel 7 are fixed on both sides of the middle of the vertical vacuum glass panel 1 and the middle position of the side wall of the reactor 1.

[0031] A horizontal plate 8 is respectively embedded at the lower end of the vertical vacuum glass panel 6 and the outer ends of the two horizontal vacuum glass panels 7. Each horizontal plate 8 is connected to a telescopic arm 9. A motor slider 10 for driving the telescopic arm 9 to extend and retract is installed at the rear end of the telescopic arm 9. The motor slider 10 consists of a motor and a worm gear, and is provided with an automatic clutch device and a built-in control board. The movement of the vacuum glass panel can be controlled by an electrical signal sent by the computer 4. Before the test, the motor slider 10 drives the vertical vacuum glass panel 6 to rise first through the telescopic arm 9. After being locked into the sealing rubber block and sealed, the two horizontal vacuum glass panels 7 are then moved into the reactor 1. The inner ends of the horizontal vacuum glass panels 7 are locked into the sealing rubber blocks on both sides of the vertical vacuum glass panels 6, thereby dividing the internal space of the reactor 1 into four sealed reaction chambers 5. In this way, different gases can be introduced into different reaction chambers 5 to form different types of hydrate particles in different reaction chambers 5. When the hydrate particle formation reaches a stable state, the vertical vacuum glass panel 6 can be downward and the two horizontal vacuum glass panels 7 can be moved left and right out of the reactor 1 for subsequent adhesion test experiments.

[0032] Shear stress testing mechanisms 11 for testing the shear stress of hydrate particles are respectively installed on the inner walls of the upper and lower reaction chambers 5 on the left side, and supporting plates 12 for placing different experimental materials are respectively installed on the inner walls of the upper and lower reaction chambers 5 on the right side.

[0033] like Figure 1 、 Figure 2 As shown, a fiber base 13 that can move up, down, left, and right is provided on the inner wall of each reaction chamber 5. Specifically, a slide rail is installed on the inner wall of each reaction chamber 5, and rollers 14 that roll with the slide rail are installed at both ends of the inner side of the fiber base 13; a first fiber holder 15 is provided at the inner end of the fiber base 13, and a second fiber holder 16 is provided at the outer end of the fiber base 13. A fiber probe 17 made of silica is embedded in the first fiber holder 15. The outer end of the fiber probe 17 passes through the second fiber holder 16 and extends out of the fiber base 13. A transverse track 18 is provided on the inner side of the fiber base 13, and a longitudinal track extending toward the outer end of the fiber base 13 is provided in the middle position of the transverse track 18. 19. A spherical roller 20 is provided at the bottom of the first fiber holder 15 for rolling cooperation with the transverse track 18 and the longitudinal track 19. The spherical roller 20 is controlled by an electric controller 21. The electric controller 21 is composed of a motor and a control chip. The coordinates inside the fiber base 13 are programmed by the computer 4 to accurately control the transverse and longitudinal movement of the first fiber holder 15. When the spherical roller 20 is located at the intersection of the longitudinal track 19 and the transverse track 18, the first fiber holder 15 can move longitudinally along the longitudinal track 19, driving the fiber probe 17 to extend out of the fiber base 13; a rotating track 22 is provided on the outside of the fiber base 13, and the second fiber holder 16 rolls with the rotating track 22 through the spherical roller 20 provided at the bottom.

[0034] Pressure sensors 23 are provided at both ends of the transverse track 18. When the spherical roller 20 touches the pressure sensor 23, it indicates that the first fiber holder 15 has moved transversely to its maximum range. At the same time, because the clamping hole of the second fiber holder 16 is slightly larger than the fiber probe 17, when the first fiber holder 15 moves longitudinally along the longitudinal track 19, the second fiber holder 16 will not clamp the fiber probe 17. When the second fiber holder 16 moves along the rotation track 22, it can also drive the fiber probe 17 to move axially, so that the fiber probe 17 has a certain rotation arc, which can meet the testing requirements of the shear stress testing mechanism 11. When the first fiber holder 15 moves along the transverse track 18, the second fiber holder 16 also moves along the rotation track 22, thereby ensuring that the fiber probe 17 moves in the same direction.

[0035] The slide rails provided on the inner walls of the four reaction chambers 5 of the reactor 1 include vertical and horizontal slide rails. Similar to the movement of the first fiber holder 15, the fiber base 13 can move up and down and forward and backward on the slide rails on the inner wall of the reactor 1. This ensures that the different hydrate particles generated on each fiber probe 17 can contact each other during testing, meeting the adhesion test requirements. The movement of all fiber probes 17 is connected to the computer 4 using radio signals, and the movement speed is set to be extremely slow.

[0036] Each of the four reaction chambers 5 is equipped with a vent tube 24 for introducing reaction gases. The test device also has a gas storage tank 25, which is connected to the vent tube 24 to facilitate the introduction of different types of pressurized gases into different reaction chambers 5. A reaction hood 26 is located outside the reactor 1. The reactor 1 is fixed in place within the hood 26 via a bracket. A transparent plate corresponding to the glass cover 28 is provided on the top surface of the hood 26. Cooling pipes are installed around the outer wall of the reactor 1 to ensure that the internal temperature of the reactor 1 meets the hydrate formation temperature. The cooling pipes are connected to a water bath 27 containing cooling water via a pipeline. During the experiment, the temperature of the reactor 1 can be adjusted through the water bath 27, with a controllable temperature range of 253.15 to 573.15 K. The solution in the water bath 27 is a mixture of ethylene glycol solution and water in a proportional manner.

[0037] like Figure 3 As shown, the shear stress testing mechanism 11 includes a motorized base 11-1 for providing power. Mounted on the motorized base 11-1 is a turntable 11-2 for testing torque. The turntable 11-2 is made of transparent glass and has a black baffle 11-3 built into the interior. A photoelectric element 11-4 and a laser light source 11-5 are mounted on the motorized base 11-1 on either side of the turntable 11-2. The rotation of the turntable 11-2 causes the light irradiated by the laser light source 11-5 on the photoelectric element 11-4 to change, thereby changing the output current of the photoelectric element 11-4. By measuring this change, the torque value of the hydrate particles can be calculated.

[0038] The laser light source 11-5 uses a green laser with a wavelength of 500nm to 560nm. It carries more energy and is easier to observe during the day, making the photoelectric element more sensitive.

[0039] like Figure 1 As shown, the liquid supply system includes a water storage tank 29, and a dripping pipe 30 is provided above each fiber probe 17 for dripping liquid onto the fiber probe 17 to form hydrate particles. The water storage tank 29 is connected to a water collecting pipe 31, and the water collecting pipe 31 is connected to the dripping pipes 30 in the four reaction chambers 5 respectively through four water supply branches, and a dosing port 32 is provided on each water supply branch to meet the need of adding reagents in the experiment.

[0040] The water storage tank 29 has a built-in water pump, which has a built-in control system. The computer 4 controls the required water flow rate to flow into the water collecting pipe 31, and distributes the water to four water branch pipes. The water in the four water branch pipes flows into the dripping pipe 30. The valve on the dripping pipe 30 has a built-in control system, which can be controlled by the computer 4. According to the experimental needs, the dripping amount is controlled to form water droplets of basically uniform size on the fiber probe 17. If it is necessary to measure the adhesion of hydrate particles with added agents, the agent can be added through the dosing port 32, fully mixed with water, and its size can be measured by the high-definition microscope 2, which is convenient for the subsequent data processing of the adhesion test. In addition, the device can directly drip in a closed and high-pressure environment, which greatly improves the experimental efficiency.

[0041] After the hydrate particles on the fiber probe 17 are stably formed, the vertical vacuum glass plate 6 and the horizontal vacuum glass plate 7 can be moved apart. Under the control of the computer 4, the hydrate particles attached to the fiber probe 17 are brought into contact with each other and then pulled apart. The elastic deformation of the fiber probe 17 can be observed through the high-definition microscope 2, and the adhesion force of the hydrate can be calculated using Hooke's law.

[0042] If it is necessary to measure the adhesion between the hydrate particles and the material wall, different materials can be replaced on the supporting plate 12 for experiment. Two square grooves are provided on the supporting plate 12, and the grooves have a certain inclination angle on both sides to facilitate the replacement of experimental materials.

[0043] Sewage recovery system: includes a sewage tank 33 located below the reactor 1, and liquid collecting pipes 34 are installed at the bottom positions on the left and right sides of the reactor 1. The liquid collecting pipes 34 are connected to sewage collection pipes 35, and the lower ends of the sewage collection pipes 35 are connected to the sewage tank 33 to facilitate centralized treatment of sewage generated by the experiment and help clean the experimental instruments.

[0044] The experimental process is briefly described as follows:

[0045] Before the experiment begins, the glass cover 28 on the reactor 1 is opened, the required wall materials are placed on the supporting plate 12, and then the glass cover 28 is sealed.

[0046] The computer 4 controls the movement of the vertical vacuum glass plate 6 and the horizontal vacuum glass plate 7 to divide the internal space of the reactor 1 into four reaction chambers 5. The computer 4 controls the water pump in the water storage tank 29 to pump water into the dripping tube 30. The valve on the dripping tube 30 is adjusted to form water droplets of the desired size. The liquid is dripped onto the fiber probe 17. If it is necessary to measure the adhesion of hydrate particles with the addition of a reagent, the reagent and water can be added through the dosing port 32 and thoroughly mixed. Then, the four reaction chambers 5 are pressurized and ventilated through the ventilation pipes 24 connected to different external gas tanks 25. At the same time, the temperature inside the reactor 1 is adjusted to the hydrate formation temperature under the set pressure using a water bath 27.

[0047] After a period of time, when the high-definition microscope 2 observes that the morphology of the hydrate particles is stable, all the vacuum glass plates are lowered, and the computer 4 controls the movement of the fiber base 13, driving the fiber probes 17 of multiple different hydrate particles to move closer to each other. If the two opposite fiber probes 17 are not long enough, the first fiber holder 15 can be moved along the longitudinal track 19 to make the fiber probes 17 extend further out of the fiber base 13. When they are close enough to be visible to the naked eye, the high-definition microscope 2 is used to observe that the different hydrate particles are in contact with each other, and then the first fiber holder 15 is controlled to move in the opposite direction to completely separate the hydrate particles. The adhesion force is measured based on their shape variables. Since multiple hydrate particles are contained on one fiber, the purpose of multiple measurements in one group can be achieved, and the test efficiency is high.

[0048] By moving the fiber base 13 up and down and forward and backward on the slide rail on the inner wall of the reactor 1 , the hydrate particles on the upper and lower fiber probes 17 can be tested.

[0049] Similarly, by moving the fiber base 13 and the first fiber holder 15 to bring the hydrate particles into contact with the material wall surface on the support plate 12 and then pulling the hydrate particles apart in the opposite direction, the adhesion between the hydrate particles and different materials can be measured.

[0050] Move the fiber base 13 and the first fiber holder 15 again, and make the hydrate particles on the fiber probe 17 contact the turntable 11-2 of the shear stress testing mechanism 11. By controlling the motor of the electric base 11-1, drive the turntable 11-2 to rotate, and observe whether the contact between the hydrate particles and the turntable 11-2 is separated by moving the high-definition microscope 2. When the contact surface between the hydrate particles and the turntable 11-2 is separated, it is the maximum torque. Due to the rotation of the turntable 11-2, the laser emitted by the laser light source 11-5 passes through the black baffle 11-3 and enters the photoelectric element 11-4. The electrical signal of the photoelectric element 36 changes. The specific torque is calculated on the computer 4, and the shear stress of the hydrate particles is calculated by the shear stress calculation formula.

[0051] After the experiment, the reactor 1 is depressurized and heated to melt the hydrate particles. The wastewater drips to the bottom of the reactor 1 and is collected by the liquid collecting pipe 34. The wastewater enters the wastewater collecting pipe 35 and is discharged into the wastewater tank 33 for centralized treatment.

[0052] The present invention can measure the adhesion between multiple groups of hydrate particles in the reactor 1 at one time, and can also measure the adhesion between different hydrate particles and between hydrate particles and the material wall. It can also measure the shear stress between different hydrate particles in one experiment, thereby achieving experimental data of multiple types and combinations of hydrate particles under the same temperature and pressure, greatly improving experimental efficiency.

[0053] During the test, by controlling the amount of dripping, the size of the water droplets formed on the glass fiber 17 can be ensured to be substantially the same, which facilitates the data processing of the subsequent adhesion test. At the same time, when hydrate formation is being performed, if the water droplets drip due to vibration or other factors, the computer 4 can be used to control the dripping again without having to terminate the experiment.

[0054] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
