Description

Technical Field

[0001] This invention relates to the field of oil storage and offloading vessel technology, specifically to a general-purpose crude oil processing mechanism for floating oil storage and offloading vessels. Background Technology

[0002] Oil storage and offloading (OSA) vessels are high-end, large-scale marine engineering equipment used for exploiting deep-sea oil and gas resources. They can process mixtures of oil, gas, and water from oil wells into qualified crude oil or natural gas. The finished crude oil is stored in cargo tanks and transported to shuttle tankers via an external transmission system when a certain amount is reached. As offshore oil and gas production facilities, they mainly consist of mooring systems, carrier systems, production process systems, and external transmission systems, encompassing dozens of subsystems. They have advantages such as strong resistance to wind and waves, wide adaptability to water depths, large oil storage and offloading capacity, and the ability to be transferred and reused. They are suitable for the development of deep-sea and shallow-sea areas and marginal oil fields far from the coast.

[0003] During oil extraction, the oil and gas mixture produced from oil wells often contains a large amount of water and mechanical impurities such as mud and sand. When crude oil with high water content enters oil processing equipment, it can damage the mechanical components. Therefore, the crude oil needs to be processed before entering the processing equipment. Crude oil is mainly dehydrated through methods such as thermochemical sedimentation dehydration, electro-dehydration, and two-stage dehydration (sedimentation followed by electro-dehydration). During thermochemical sedimentation dehydration, a demulsifier needs to be added to the crude oil. A demulsifier is a chemical agent that can break down emulsions. Adding a demulsifier to crude oil separates the oil and water in the emulsified oil-water mixture, making... The goal is to achieve crude oil dehydration to ensure the water content standard for crude oil exports. However, due to the complexity and variability of crude oil, and the varying degrees of emulsification (emulsion aging, large emulsion dispersion, high viscosity, etc.), the amount of demulsifier added normally is often insufficient to stably dehydrate crude oil whose properties have changed. Because the daily processing capacity of dehydration equipment is large, it is difficult for staff to detect changes in crude oil properties immediately, leading to the entry of crude oil with high water content into the processing equipment, which can easily damage it. Therefore, we propose a general-purpose crude oil processing mechanism for floating storage and offloading (FSO) vessels. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention utilizes a collection frame to sample crude oil inside a tank, and then transports the sample to the outside for testing via a conveying pipe. Under the action of a connecting unit and a limiting transmission unit, the driving component moves the collection frame to adjust its position, so that the collection frame can sample crude oil after stirring.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-12This invention provides a technical solution: a general-purpose floating storage and offloading (FSO) oil tanker crude oil processing mechanism. This invention addresses the technical problems mentioned in the background art by improving upon the following: It includes a processing tank 2 fixedly installed on the hull 1, wherein a dehydration processing tank 21 is installed inside the processing tank 2. Further, the dehydration processing tank 21 consists of an end cap 22 and a tank body 23. An agitator 3 is installed inside the tank body 23, and the end of the agitator 3 is rotatably connected to the inner wall of the end cap 22. A frame 7 is fixedly installed on the top of the end cap 22, and a servo motor 9 is fixedly installed on the top of the frame 7. The output end of the servo motor 9 penetrates the inner wall of the top of the frame 7 and extends into it. Furthermore, a sealing sleeve 6 is fixedly installed inside the tank body 23, wherein a collection frame 4 is slidably connected to the sealing sleeve 6. The collection frame 4 is initially located inside the sealing sleeve 6 (before sampling), and a conveying pipe 5 is installed on the collection frame 4. The end of the delivery pipe 5 is located outside the tank 23 and is in communication with the existing collection sleeve, so that when the collection frame 4 descends, the crude oil sample enters the collection frame 4 and is transported along the delivery pipe 5 to the outside of the tank 23 (i.e., inside the collection sleeve). In this invention, the water content of each batch of crude oil is tested multiple times and the results of each test are compared. The staff tests the water content of the sample inside the collection sleeve. The sealing sleeve 6 is equipped with a driving component 8, which is used to adjust the position of the collection frame 4, i.e., control the sampling status of the collection frame 4. The present invention has a transmission component 10 installed on the output end of the servo motor 9. The transmission component 10 includes a connecting unit 11 located inside the frame 7, wherein the end of the stirring part 3 is located inside the connecting unit 11, and a limiting transmission unit 12 located inside the frame 7. The limiting transmission unit 12 is used to control the directional movement of the driving component 8.

[0033] Furthermore, the driving component 8 in this invention includes a lead screw 81 installed inside the sealing sleeve 6, and an extension component 82 is fixedly installed on the top of the lead screw 81. The end of the extension component 82 penetrates the inner wall of the sealing sleeve 6 and extends to its outside. A snap-fit ​​post 83 is installed at the end of the extension component 82. A driving panel 84 is also installed on the lead screw 81, and a guide rod 85 that is slidably connected to the driving panel 84 is installed inside the sealing sleeve 6. A linkage post 86 is also connected between the driving panel 84 and the top of the collection frame 4. That is, when the lead screw 81 rotates, the driving panel 84 on it performs a directional movement under the action of the guide rod 85. The driving panel 84 drives the collection frame 4 to perform synchronous position adjustment through the linkage post 86. It should be noted that the bottom of the collection frame 4 in this invention is equipped with sealing rubber.

[0034] As a further limitation of the present invention, the connecting unit 11 includes a force-receiving disk 111 disposed inside the frame 7, and a force-receiving rod 112 is fixedly installed on one side of the force-receiving disk 111 (the side closer to the output end of the servo motor 9). A fixing sleeve 113 is fixedly installed on the side of the force-receiving disk 111 away from the force-receiving rod 112, and the stirring part 3 is located inside the fixing sleeve 113. Telescopic sliding columns 117 are fixedly installed on both the inner and outer walls of the fixing sleeve 113, and a limiting sleeve 114 is fixedly installed on the frame 7. The limiting sleeve 114 is provided with a spiral groove 115 and an annular groove 116 that are slidably connected to the telescopic sliding column 117 (on the outer wall of the fixing sleeve 113). Furthermore, the ends of the annular groove 116 and the spiral groove 115 are in communication. The stirring section 3 is provided with a vertical groove 118 and an annular groove 119 that are slidably connected to the telescopic sliding column 117 (on the inner wall of the fixed sleeve 113). The ends of the annular groove 119 and the vertical groove 118 are in communication. Further, guide plates 110 are installed inside both the annular groove 116 and the annular groove 119. The guide plate 110 in the annular groove 116 is installed at the intersection of the annular groove 116 and the spiral groove 115. The guide plate 110 in the annular groove 119 is installed at the intersection of the annular groove 119 and the vertical groove 118. Specifically, see attached... Figure 5 , 7 As shown in Figure 8: In this invention, the two guide plates 110 have an inclined surface on one side and a right-angled surface on the other. The guide plate 110 within the annular groove 116 has a right-angled sidewall near the end of the spiral groove 115, while the other side is an inclined surface. That is, when the telescopic slide 117 moves to the inclined surface, it moves along the inclined surface of the guide plate 110 (i.e., the telescopic slide 117 retracts). When it reaches the right-angled surface, the telescopic slide 117 extends. The guide plate 110 in the second groove 119 has a right-angled surface on one side near the end of the vertical groove 118 and an inclined surface on the other side; a force-applying disk 16 and an action disk 161 are fixedly installed in parallel on the output end of the servo motor 9, wherein the force-applying disk 16 is located above the action disk 161, and an action rod 162 is fixedly installed on the action disk 161. The force-receiving rod 112 is located on the movement trajectory of the action rod 162, and multiple force-applying rods 163 are installed on the force-applying disk 16;

[0035] Specifically, when the servo motor 9 starts, its output drives the force-applying disk 16 and the action disk 161 to rotate synchronously. When the action disk 161 rotates, its action rod 162 acts on the force-receiving rod 112 on the force-receiving disk 111. The force-receiving rod 112 is subjected to force, which drives the force-receiving disk 111 to rotate. The fixed sleeve 113 on one side of the force-receiving disk 111 rotates inside the limiting sleeve 114. During the rotation, the telescopic sliding column 117 on the outer wall of the fixed sleeve 113 moves along the inner wall of the spiral groove 115. During the limited movement, the telescopic sliding column 117 on the inner wall of the fixed sleeve 113 acts on the inner wall of the vertical groove 118 during rotation, so that the stirring part 3 rotates synchronously with the fixed sleeve 113. Further, when the telescopic sliding column 117 on the outer wall of the fixed sleeve 113 slides along the inner wall of the spiral groove 115, the fixed sleeve 113 rotates and descends. That is, the force-bearing disc 111 and the force-bearing rod 112 on the fixed sleeve 113 both move synchronously. When the telescopic sliding column 117 on the outer wall of the fixed sleeve 113 moves... When the object reaches the interior of the first annular groove 116, the telescopic sliding column 117 on the inner wall of the fixed sleeve 113 moves into the second annular groove 119. At this time, the fixed sleeve 113 is rotatably connected to the stirring part 3 under the action of the telescopic sliding column 117 and the second annular groove 119. It should be noted that the rotation direction of the servo motor 9 is positive at this time, that is, the end of the telescopic sliding column 117 contacts the inclined surface of the guide plate 110, and the force rod 112 on the force-bearing disk 111 is still on the movement trajectory of the action rod 162. 162 acts on the force-bearing rod 112, and the force-bearing disc 111 drives the fixed sleeve 113 to rotate under the action of the force-bearing rod 112. In this state, the telescopic sliding column 117 on the inner and outer walls of the fixed sleeve 113 rotates in the annular groove 119 and the annular groove 116. At this time, the stirring part 3 does not rotate. It should be noted that the servo motor 9 is started after the demulsifier is added. Then, the stirring part 3 stirs the crude oil inside the tank 23 after the demulsifier is added, that is, it helps the demulsifier and crude oil to mix fully.

[0036] As a further limitation of the present invention, the limiting transmission unit 12 includes a support sleeve 121 fixedly installed inside the frame 7, and a circular disc frame 122 slidably connected to its inner wall is installed inside the support sleeve 121. A drive disc 123 rotatably connected to the circular disc frame 122 is also fixedly installed on the circular disc frame 122, and the drive disc 123 is in contact with the bottom of the force-receiving disc 111 (to reduce friction, the part of the drive disc 123 in contact with the force-receiving disc 111 (bottom) in the present invention is rotatably connected). A spring body 124 is symmetrically fixedly installed at the bottom of the frame 7, and the end of the spring body 124 is in contact with the bottom of the circular disc frame 122. A fixing column 125 is fixedly installed on the drive disc 123, and the end of the fixing column 125 is located at the force-applying disc 16. Above the fixed column 125, a movable disk 126 is fixedly installed at the end of the fixed column 125, and multiple transmission columns 127 are also fixedly installed on the movable disk 126. In the initial state (i.e., when the servo motor 9 is not started), the transmission column 127 is located above the force-applying disk 16, and a through column 128 is fixedly installed on the other side of the drive disk 123 (the side away from the fixed column 125). The end of the through column 128 passes through the inner wall of the support sleeve 121, the frame 7 and the end cover 22 in sequence and extends into the end cover 22. A through bracket 129 is fixedly installed at the end of the through column 128 located inside the end cover 22. In the initial state, the through column 128 and the through bracket 129 are located above the snap-fit ​​column 83, and the snap-fit ​​column 83 is on the movement trajectory of the through bracket 129 (and slides between them).

[0037] Specifically, when the servo motor 9 starts, its output drives the force-applying disk 16 and the action disk 161 to rotate synchronously. The action disk 161 rotates, and its action rod 162 acts on the force-receiving rod 112 on the force-receiving disk 111. The force-receiving rod 112, under the applied force, drives the force-receiving disk 111 to rotate. The fixed sleeve 113 on the side wall of the force-receiving disk 111 rotates inside the limiting sleeve 114. At this time, the telescopic sliding column 117 on the outer wall of the fixed sleeve 113 slides along the inner wall of the spiral groove 115, thus limiting the movement of the fixed sleeve 113. In this state, the telescopic sliding column 117 on the inner wall of the fixed sleeve 113 acts on the vertical groove 118 of the stirring section 3, causing the stirring section 3 to rotate (while the telescopic sliding column 117 on the inner wall of the fixed sleeve 113 slides along the inner wall of the spiral groove 115). The wall performs a limiting descent action, which assists in the rapid mixing between crude oil and demulsifier; during the rotation and descent of the fixed sleeve 113, its bottom acts on the drive disc 123, and the drive disc 123 is subjected to force to drive the circular disc frame 122 to perform a synchronous descent action (the circular disc frame 122 performs a limiting descent action on the inner wall of the support sleeve 121). During the descent action of the circular disc frame 122, it compresses the spring body 124 at the bottom of the frame 7. At the same time, the fixed column 125 on the drive disc 123 drives the moving disc 126 to perform a descent action. That is, the transmission column 127 on the moving disc 126 moves closer to the movement trajectory of the force rod 163 (on the force-applying disc 16), and the through column 128 on the other side of the drive disc 123 drives the through bracket 129 on it to move closer to the snap-fit ​​column 83.

[0038] After the stirring part 3 rotates two revolutions in the positive direction, the crude oil and the demulsifier are basically completely mixed. The telescopic sliding column 117 on the inner and outer walls of the fixed sleeve 113 is located in the annular groove 2 119 and the annular groove 116.When the two telescopic sliding columns 117 are located at the initial ends of the annular groove 116 and the annular groove 119 (i.e., the installation position of the guide plate 110), the transmission column 127 is on the movement trajectory of the force-applying rod 163, and the local area of ​​the locking column 83 is also located within the through bracket 129. At this time, the servo motor 9 continues to rotate (rotating nearly one revolution in the positive direction), meaning the end of the telescopic sliding column 117 moves to the initial end of the inclined surface of the guide plate 110. Its output end drives the force-applying disk 16 to continue rotating. The force-applying rod 163 on the force-applying disk 16 acts on the transmission column 127, causing the transmission column 127 to be subjected to a force that drives the moving disk 126 to rotate. This causes the driving disk 123 and the through column 128 to rotate synchronously with it. Under the action of the through bracket 129 and the snap-fit ​​post 83, the extension 82 and the lead screw 81 at its end rotate. When the lead screw 81 rotates, the drive panel 84 on it is oriented under the action of the guide rod 85. The drive panel 84 drives the collection frame 4 to sample the crude oil in the tank 23 through the linkage column 86. The collection frame 4 stays in the crude oil for 5 seconds. After the sampling is completed, the servo motor 9 reverses, and the telescopic sliding column 117 on the inner and outer walls of the fixed sleeve 113 will rotate in the opposite direction. When it rotates in the opposite direction for nearly one revolution, the telescopic sliding column 117 moves to the right angle surface of the guide plate 110 and returns to the vertical groove 118 and the spiral groove 115 under the action of the guide plate 110. That is, the fixed sleeve 113, the force-bearing disc 111 and its upper part are in the vertical groove 118 and the spiral groove 115. The force-bearing rod 112 rises, and the circular disc frame 122, under the action of the spring body 124, drives the drive disc 123 to rise. During the process of the servo motor 9 rotating in the opposite direction for nearly one revolution, the transmission column 127 remains on the movement trajectory of the force-applying rod 163. When the telescopic sliding column 117 is located in the vertical groove 118 and the spiral groove 115, the transmission column 127 leaves the movement trajectory of the force-applying column, and at the same time, the locking column 83 does not contact the through bracket 129. The drive panel 84 on the lead screw 81, under the action of the linkage column 86, drives the collection frame 4 back to the initial state. The crude oil sample enters the collection frame 4 and is transported to the tank 23 along the conveying pipe 5. Externally (i.e., inside the collection sleeve), staff test the water content of the sample inside the collection sleeve. It should be noted that if the collection frame 4 remains in the crude oil for 5 seconds, the crude oil will enter the collection sleeve through the delivery pipe 5. Generally, this invention performs about three tests on each batch of crude oil. The first test is performed after adding the demulsifier, the second test is performed during the middle of dehydration, and the third test is performed during the later stage of dehydration. The results of the three tests are compared to observe the dehydration status of the crude oil. If the results of the second and third tests meet the expectations, the next step can be carried out. If the results of the second test do not meet the expectations, one more test is required, and the results of the third and fourth tests are observed. If the standard is met, the next step can be carried out.

[0039] A mounting bracket 13 is fixedly installed on the outside of the tank body 23. An electromagnet 14 is installed at the bottom of the mounting bracket 13, and a feeding mechanism 15 is provided inside the mounting bracket 13. As a further limitation of the present invention, the feeding mechanism 15 includes a partition 151 fixedly installed inside the mounting bracket 13, and a feeding sleeve 152 that is slidably connected to the inner wall of the partition 151 is installed on the partition 151. A magnet body 153 is installed at the bottom of the feeding sleeve 152, and the electromagnet 14 generates a repulsive force on the magnet body 153 when energized. Multiple support shafts are installed at the bottom of the feeding sleeve 152. 154, and the support shaft 154 is slidably connected to the partition plate 151. A return spring 155 is also connected between the partition plate 151 and the end of the support shaft 154. A discharge pipe 156 is installed on the feed sleeve 152, and the end of the discharge pipe 156 is located inside the tank body 23. It should be noted that the feed sleeve 152 has a graduated groove, and a solenoid valve is installed on the discharge pipe 156. Both the solenoid valve and the electromagnet 14 are electrically connected to the central control unit. It should be noted that the solenoid valve is a prior art structure, and therefore, this invention does not describe it in detail. When the results of the first and second tests differ from the expected results, a demulsifier can be added appropriately (the amount of demulsifier added is related to the dehydration rate). Specifically, the current applied to electromagnet 14 is related to the amount of demulsifier added. When electromagnet 14 is energized, it applies a repulsive force to magnet body 153, causing magnet body 153 to drive the feed sleeve 152 to rise (the rising distance of feed sleeve 152 is related to the current applied to electromagnet 14). At this time, the solenoid valve is open, and the operator adds demulsifier into feed sleeve 152, controlling the amount of demulsifier added according to the scale value. After the feed sleeve 152 rises, the surface of the fixed frame 13 is flush with a certain mark on the scale (at which point the demulsifier is added to the flush mark), the electromagnet 14 is de-energized, and under the action of the return spring 155, the feed sleeve 152 returns to its initial state (i.e., it contacts the surface of the partition plate 151). At this time, the solenoid valve closes, and the demulsifier is added into the tank 23. Thus, through the structural design of the present invention, crude oil can be detected, so that when the physical properties of crude oil change, the staff can add an appropriate amount of demulsifier in time to prevent crude oil with high water content from entering the processing equipment.
