Description

Technical Field

[0001] This utility model relates to the field of three-phase separator technology, and more specifically, to a skid-mounted high-efficiency three-phase horizontal separator. Background Technology

[0002] Three-phase separators are indispensable equipment in the treatment of produced fluids in oilfields, primarily used to effectively separate mixed oil, gas, and water phases. Existing separators mostly rely on gravity settling, and their separation efficiency is closely related to fluid properties, temperature, pressure, and flow rate. Traditional horizontal separators often combine single-stage oil-water gravity settling with simple gas-liquid separation. Upon entering the equipment, the fluid easily generates eddies and turbulence, leading to an unstable oil-water interface and prolonged separation time. Simultaneously, due to uneven droplet size distribution, some fine droplets escape with the gas phase or are entrained in the liquid phase, resulting in incomplete separation. Furthermore, existing equipment generally has a fixed structure, low integration, and is difficult to maintain and relocate. It cannot maintain stable separation efficiency under different operating conditions and lacks the ability to adjust for changes in the oil-water phase, thus limiting its adaptability under high water cut or variable flow rate conditions. Utility Model Content

[0003] In view of this, this utility model addresses the shortcomings of the prior art by proposing a skid-mounted high-efficiency three-phase horizontal separator, aiming to solve the problems of turbulent gas-liquid flow, unstable oil-water interface, and severe droplet entrainment in the prior art, which lead to low three-phase separation efficiency, incomplete separation, and frequent operation and maintenance.

[0004] This utility model provides a skid-mounted high-efficiency three-phase horizontal separator, comprising: The cylindrical body is equipped with a filter module and a separation module, both of which are located inside the cylindrical body. The filtration module includes an inlet distributor, a flow guiding cavity, a corrugated plate coalescer, a primary separation unit, and a secondary separation unit. The inlet distributor is located inside the cylinder, the flow guiding cavity is located on the inner wall of the cylinder, one end of the inlet distributor is connected to the flow guiding cavity, the corrugated plate coalescer is located on the inner wall of the cylinder, and both the primary and secondary separation units are located on the inner wall of the cylinder. The separation module is provided with an oil chamber, a water chamber, a liquid level regulating device, and a baffle plate. The oil chamber is connected to the inner wall of the cylinder, the water chamber is connected to the inner wall of the cylinder, the liquid level regulating device is located in the water chamber, and a baffle plate is provided between the water chamber and the oil chamber.

[0005] Furthermore, the outer wall of the cylinder is provided with a liquid inlet, which is connected to the other end of the inlet distributor.

[0006] Furthermore, the flow guiding cavity is provided with a flow guiding plate, and one end of the inlet distributor passes through the flow guiding plate.

[0007] Furthermore, the outer wall of the cylinder is also provided with a first drain outlet, a second drain outlet and a third drain outlet. The first drain outlet is connected to the guide cavity, and the second drain outlet and the third drain outlet are both connected to the cylinder.

[0008] Furthermore, the outer wall of the cylinder is also provided with a first inspection port, a second inspection port, a third inspection port and a pressure guiding interface, and the first inspection port, the second inspection port, the third inspection port and the pressure guiding interface are all connected to the cylinder.

[0009] Furthermore, the cylinder is also equipped with a mist eliminator, which is disposed on the inner side wall of the cylinder.

[0010] Furthermore, the mist eliminator is provided with an exhaust port, which is located on the side wall of the cylinder.

[0011] Furthermore, the cylinder is provided with a first partition and a second partition. The first partition is connected to the water chamber, and the second partition is connected to the oil chamber. The first partition and the second partition are connected, and the barrier plate is connected to the connection between the second partition and the first partition. The first partition is higher than the second partition.

[0012] Furthermore, the liquid level regulating device is provided with a straight pipe interface, a riser, an elbow interface and a support plate. The straight pipe interface passes through the first partition plate, the elbow interface is located in the water chamber, the riser and the pressure guiding interface are coaxially arranged, and the support plate is connected to the side wall of the elbow interface.

[0013] Furthermore, the outer wall of the cylinder is also provided with a water outlet and an oil outlet, the water outlet being connected to the water chamber and the oil outlet being connected to the oil chamber.

[0014] Compared with existing technologies, this invention offers the following advantages: By incorporating a filtration module and a separation module within the cylinder, a multi-stage processing structure is achieved for the mixed fluid, from initial dispersion and flow pattern shaping to fine oil-water separation. The inlet distributor in the filtration module uniformly distributes and initially degasses the incoming gas-liquid mixture, preventing high-speed jets from directly impacting the inner wall of the cylinder and causing turbulence, thus ensuring flow field stability and improving the efficiency of subsequent separation stages. The guide cavity, located on the inner wall of the cylinder, further rectifies and guides the fluid after it passes through the inlet area, ensuring a uniform distribution of the fluid velocity and pressure fields and providing stable inlet conditions for the corrugated plate coalescer. The corrugated plate coalescer utilizes the inertial collision and surface tension effect of droplets within the corrugated channel to coalesce small droplets into larger ones, accelerating the oil-water stratification process and improving liquid-liquid separation efficiency. The multi-stage arrangement of the primary and secondary separation units further enhances the gravity stratification effect, resulting in a clear oil-water interface and reducing entrainment. In the separation module, the oil chamber and water chamber are spatially distributed along the cylinder body, and are stably separated at the phase boundary by a baffle plate to avoid mutual disturbance. The liquid level regulating device is located in the water chamber, which can maintain a constant water phase height according to the change in the volume of the inflowing liquid, thereby ensuring the long-term stability of the separation boundary between the oil chamber and the water chamber. The overall structure realizes a continuous process from gas-liquid separation to oil-water fine separation, and has the advantages of smooth flow, thorough separation, and adaptability to complex working conditions.

[0025] like Figure 1-5 As shown, a skid-mounted three-phase horizontal separator according to a preferred embodiment of the present invention includes: The cylinder 10 is equipped with a filter module and a separation module, both of which are located inside the cylinder 10. The filter module is equipped with an inlet distributor 20, a flow guiding cavity 30, a corrugated plate coalescer 40, a primary separation unit 50, and a secondary separation unit 60. The inlet distributor 20 is located inside the cylinder 10, the flow guiding cavity 30 is located on the inner wall of the cylinder 10, one end of the inlet distributor 20 is connected to the flow guiding cavity 30, the corrugated plate coalescer 40 is located on the inner wall of the cylinder 10, and both the primary separation unit 50 and the secondary separation unit 60 are located on the inner wall of the cylinder 10. The separation module is equipped with an oil chamber 90, a water chamber 80, a liquid level regulating device 70, and a baffle plate 802. The oil chamber 90 is connected to the inner wall of the cylinder 10, the water chamber 80 is connected to the inner wall of the cylinder 10, the liquid level regulating device 70 is located in the water chamber 80, and a baffle plate 802 is provided between the water chamber 80 and the oil chamber 90.

[0026] It should be noted that by sequentially arranging the filtration module and separation module inside the cylinder 10, the mixed fluid completes the entire process from initial distribution to oil-water phase separation during continuous flow. The filtration module consists of an inlet distributor 20, a flow guide cavity 30, a corrugated plate coalescer 40, a primary separation unit 50, and a secondary separation unit 60. The inlet distributor 20 is installed inside the left end of the cylinder 10 and connected to the liquid inlet 201. It is used to uniformly disperse the mixed liquid and reduce flow velocity impact, preventing concentrated fluid flow from causing turbulence in the separation zone, thereby improving separation stability. The flow guide cavity 30 is arranged on the inner wall of the cylinder 10 and connected to the inlet distributor 20. Through the flow guide plate 301, the mixed liquid is guided smoothly along the axial direction of the cylinder 10 to the area of ​​the corrugated plate coalescer 40, making the flow field distribution uniform and reducing vortices and backflow. The corrugated plate coalescer 40 is fixed to the inner wall of the cylinder 10. Its corrugated surface structure promotes the coalescence of fine droplets on the surface, forming larger droplets, increasing the gravity settling velocity of the droplets and reducing the separation time. The primary separation unit 50 is located after the corrugated plate coalescer 40, mainly completing the preliminary oil-water separation process, causing most of the oil phase to float and some of the water phase to sink. The secondary separation unit 60 is located downstream of the primary separation unit 50, used to further separate residual entrained droplets, ensuring that the fluid output from the separation zone is purer. The separation module includes an oil chamber 90, a water chamber 80, a liquid level regulating device 70, and a baffle plate 802. The baffle plate 802 is located between the oil chamber 90 and the water chamber 80, serving to stabilize the interface and limit the stratification area. After being processed by the filtration module, the liquid flows from the upper part of the cylinder 10 into the separation module. The light phase oil floats directly to the oil chamber 90 and is discharged through the oil outlet 110, while the heavy phase water settles to the bottom under gravity. It is then guided into the water chamber 80 by the liquid level regulating device 70 located inside the water chamber and discharged through the water outlet 109. The lower end of the liquid level regulating device 70 is connected to the bottom separation zone of the cylinder 10 to guide the water phase accumulated at the bottom to the water chamber 80. The upper end is connected to the upper space of the cylinder 10 through a riser 703 to maintain gas-liquid pressure balance and prevent water flow obstruction or air blockage. Through the above structural arrangement, the device achieves the separation of the oil and water phases, with a stable oil-water interface and clear fluid flow direction. It has the advantages of high separation accuracy, good operational stability, compact structure, and convenient maintenance.

[0027] In some embodiments of this application, the outer wall of the cylinder 10 is provided with a liquid inlet 201, which is connected to the other end of the inlet distributor 20.

[0028] It should be noted that by setting an inlet 201 on the outer wall of the cylinder 10 and connecting the inlet 201 to the other end of the inlet distributor 20, the orderly introduction of the mixture into the cylinder 10 from the outside is achieved. The inlet 201 is located on the outer wall of the left end of the cylinder 10, aligned with the axial direction of the inlet distributor 20, so that the mixed gas-liquid flow first passes through the guiding and diffusion structure of the inlet distributor 20 after entering the cylinder 10, forming a uniform flow field. When the mixture passes through the inlet distributor 20, large droplets are removed by the internal baffle and inertial separation, thereby reducing the load on subsequent separation units. The separated oil-water mixture flows along the inner wall of the cylinder 10 under gravity into the low-velocity region at the bottom, forming an underflow layer, providing stable inlet conditions for subsequent phase separation. After pre-separation, the liquid enters the flow pattern distribution and adjustment device through the drop pipe, where the flow pattern is further regulated and homogenized, ensuring a stable and continuous flow before entering the guide cavity 30, corrugated plate coalescer 40, primary separation unit 50, and secondary separation unit 60. This structural design allows for initial liquid removal and flow field homogenization of the mixture upon entering the cylinder 10, avoiding turbulence and re-entrainment, improving efficiency in the initial separation stage and overall separation stability, resulting in smooth inflow, clear phase separation, and low overall energy consumption.

[0029] In some embodiments of this application, the flow guiding cavity 30 is provided with a flow guiding plate 301, and one end of the inlet distributor 20 passes through the flow guiding plate 301.

[0030] It should be noted that a guide plate 301 is installed inside the flow guiding cavity 30. The guide plate 301 and the inlet distribution component form a stable inlet structure. One end of the inlet distribution component passes through the guide plate 301, thus creating a restricted flow path for the incoming mixture as it passes through the guide plate 301. The guide plate 301 has several inclined flow guiding channels or gaps to guide the gas-liquid two-phase flow to diffuse uniformly along the axial direction of the cylinder 10 and weaken the impact kinetic energy at the inlet. The gas enters the coalescing zone through the upper channel of the guide plate 301, while the liquid disperses downward under the action of gravity, creating a stratified and horizontally stable flow field within the flow guiding cavity 30. Through this arrangement, the combination of the inlet distribution component and the guide plate 301 can improve the flow field distribution, reduce turbulence intensity, and suppress secondary entrainment, providing stable inlet conditions for the subsequent corrugated plate coalescer 40 and separation unit, thereby improving the overall separation efficiency and the controllability of system operation.

[0031] In some embodiments of this application, the outer wall of the cylinder 10 is also provided with a first drain outlet 101, a second drain outlet 102 and a third drain outlet 103. The first drain outlet 101 is connected to the guide cavity 30, and the second drain outlet 102 and the third drain outlet 103 are both connected to the cylinder 10.

[0032] It should be noted that the first drain port 101 is directly connected to the guide chamber 30, mainly used to discharge high-density impurities or deposited liquid accumulated in the guide chamber 30 during the primary separation process, preventing local blockage in the inlet area. The second drain port 102 is located in the middle of the cylinder 10 and connected to the main separation zone, used for periodically discharging the intermediate layer residual liquid or entrained matter precipitated during the separation process. The third drain port 103 is located before entering the oil chamber 90 and water chamber 80, and is connected to the bottom oil-water sediment layer, allowing for thorough emptying and cleaning during shutdown or maintenance. Through this three-stage drain structure, the opening can be controlled separately according to the operating stage or drain requirements, forming a coordinated mechanism of zoned draining and timed cleaning, which not only ensures the cleanliness of the fluid in the guide and separation zones, but also extends the continuous operation cycle of the equipment, improving the stability and maintenance convenience of the system.

[0033] In some embodiments of this application, the outer side wall of the cylinder 10 is also provided with a first inspection port 104, a second inspection port 105, a third inspection port 106 and a pressure guiding interface 108, all of which are connected to the cylinder 10.

[0034] It should be noted that the first inspection port 104 is positioned opposite the flow guide cavity 30, facilitating cleaning of the inlet flow guide area, disassembly and assembly of the flow guide plate 301, and flow field inspection during shutdown or inspection, ensuring long-term stability of the inlet flow. The second inspection port 105 is located on the side wall of the main separation zone, allowing direct observation of the working status of the corrugated plate coalescer 40 and separation elements, used to check for liquid re-entrainment or abnormal oil-water stratification. The third inspection port 106 is located at the end of the oil-water separation zone, mainly used for cleaning residual deposits near the oil-water interface and checking the operation of the liquid level regulating device 70. The pressure-conducting interface 108 is connected to the interior of the cylinder 10, used to acquire pressure signals from various areas inside the cylinder 10 in real time. An external pressure sensor can be used to monitor the operating status and determine blockages or abnormal liquid levels. This structural arrangement provides the equipment with good maintainability and operational visibility, realizing the coordinated functions of zoned detection, independent maintenance, and pressure monitoring, thereby improving the safety and maintenance efficiency of the equipment.

[0035] In some embodiments of this application, the cylinder 10 is further provided with a mist eliminator 112, which is disposed on the inner side wall of the cylinder 10.

[0036] It should be noted that the mist eliminator 112 adopts a wire mesh or multi-layer corrugated plate structure. It utilizes the inertial collision, diffusion, and gravitational settling effects of gas flowing through a fine channel to cause residual liquid droplets to condense and flow back along the inner wall of the cylinder 10 to the lower liquid phase zone, thereby reducing the droplet content in the gas phase. This structural arrangement improves the purity of gas-liquid separation, reduces the liquid content when the gas phase is discharged, and prevents liquid carryover or corrosion problems in subsequent pipelines.

[0037] In some embodiments of this application, the mist trap 112 is provided with an exhaust port 107, which is disposed on the side wall of the cylinder 10.

[0038] It should be noted that by directly connecting the exhaust port 107 to the mist eliminator 112, the gas can be discharged in a stable flow state after droplet capture, avoiding re-entrainment caused by sudden changes in flow velocity. The exhaust port 107 is typically designed with a circular or elliptical cross-section and is connected to the external pipeline with a flange seal to ensure the airtightness and safety of the exhaust process. This structural design allows the gas to form a uniformly distributed discharge path after the mist eliminator 112, maintaining stable pressure inside the separation zone, reducing the disturbance of gas turbulence to the liquid phase zone, thereby further improving the overall efficiency and operational stability of the three-phase separation.

[0039] In some embodiments of this application, the cylinder 10 is provided with a first partition 801 and a second partition 901. The first partition 801 is connected to the water chamber 80, and the second partition 901 is connected to the oil chamber 90. The first partition 801 is connected to the second partition 901, and the baffle 802 is connected to the connection between the second partition 901 and the first partition 801. The first partition 801 is higher than the second partition 901.

[0040] It should be noted that the first baffle 801 is connected to the water chamber 80 to limit the flow range of the aqueous phase and form a stable liquid level zone; the second baffle 901 is connected to the oil chamber 90 to guide the oil phase to float upwards and enter the collection area of ​​the oil chamber 90. The first baffle 801 and the second baffle 901 are connected in the middle to form a separation frame structure. The baffle 802 is set at the connection between the two to prevent turbulence interference at the oil-water interface and stabilize the interface morphology. Since the first baffle 801 is higher than the second baffle 901, when the liquid flows in the cylinder 10, it can form an oil-water stratification path from bottom to top, causing the less dense oil phase to float upwards and flow into the oil chamber 90, while the more dense water phase flows to the water chamber 80 through the bottom channel, achieving natural gravity stratification. Through this high-low staggered and structural connection design, the backflow and disturbance in the oil-water mixing zone can be suppressed, the stability of the separation interface can be improved, thereby improving the oil-water separation accuracy and the continuity of fluid transportation.

[0041] In some embodiments of this application, the liquid level regulating device 70 is provided with a straight pipe interface 701, a riser 703, an elbow interface 702 and a support plate 111. The straight pipe interface 701 passes through the first partition 801, the elbow interface 702 is disposed in the water chamber 80, the riser 703 is coaxially arranged with the pressure guiding interface 108, and the support plate 111 is connected to the side wall of the elbow interface 702.

[0042] It should be noted that the straight pipe interface 701 passes through the first partition 801, allowing the bottom liquid to enter the regulating channel from the separation zone; the riser 703 is coaxially arranged with the pressure guiding interface 108, which can realize the liquid level sensing and pressure transmission of the water phase, and also facilitate the monitoring of the liquid level change trend through the pressure guiding interface 108; the elbow interface 702 is set in the water chamber 80, used to guide the lower accumulated liquid into the water chamber 80 along the curved channel, realizing the directional transportation of the water phase and liquid level balance; the support plate 111 is fixed on the side wall of the elbow interface 702, which plays a role in stabilizing the structure and avoiding the shaking of the device caused by fluid impact. Through this structure, the liquid level regulating device 70 can automatically balance the liquid level difference in different areas of the cylinder 10 during operation, keep the oil-water interface stable, and ensure that the water phase is discharged into the water chamber 80 in a timely manner, preventing water phase retention or oil phase entrainment, and improving the continuity and reliability of three-phase separation.

[0043] In some embodiments of this application, the outer wall of the cylinder 10 is also provided with a water outlet 109 and an oil outlet 110, the water outlet 109 being connected to the water chamber 80 and the oil outlet 110 being connected to the oil chamber 90.

[0044] It should be noted that the oil outlet 110 is located in the upper oil chamber 90 area of ​​the cylinder 10, allowing the rising oil phase to be smoothly discharged under static pressure, avoiding the carrying of the bottom water phase; the water outlet 109 is located in the lower part of the cylinder 10 and connected to the water chamber 80, allowing the deposited water phase to be stably discharged after the liquid level reaches equilibrium. Through the dual-outlet structure distributed vertically, natural pressure differential discharge can be achieved based on the height difference between the oil and water interfaces, eliminating the need for external power assistance and reducing energy consumption and structural complexity. This arrangement also ensures that the oil and water discharge processes do not interfere with each other, maintaining a stable flow field within the separation zone, thereby improving the thoroughness of oil-water separation and the continuity of equipment operation.

[0045] The working process of this utility model is as follows: The mixed material enters the inlet 201 through the external pipeline and then enters the cylinder 10. First, it passes through the inlet distributor 20 to achieve uniform fluid distribution and remove large droplets, completing the initial gas-liquid separation. The separated gas enters the upper space, while the liquid flows along the inner wall of the cylinder 10 to the bottom guide cavity 30. Under the guidance of the guide plate 301, the flow direction and velocity distribution are adjusted before entering the corrugated plate coalescer 40 area. The corrugated plate coalescer 40 refines and coalesces the liquid phase, causing small droplets to converge into larger droplets, improving the subsequent separation efficiency. The coalesced liquid continues to flow to the primary separation unit 50, where the oil and water are initially separated by density difference. The lighter oil phase moves upward, while the heavier water phase sinks. The fluid after primary separation enters the secondary separation unit 60, where the oil and water are further separated and diverted to the corresponding areas. The upper oil phase converges and flows into the oil chamber 90 from the top, while the lower water phase is transported to the water chamber 80 via the bottom liquid level regulating device 70. After the gas passes through the mist eliminator 112 at the top of the cylinder 10 to remove residual droplets, it is discharged through the exhaust port 107. Finally, the fluids in the oil chamber 90 and the water chamber 80 are discharged through the oil outlet 110 and the water outlet 109, respectively, completing the entire process of gas, oil and water separation and discharge.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
