Description

Technical Field

[0001] The present invention relates to the technical field of Fischer-Tropsch reaction systems, and in particular to a heavy oil separator. Background Art

[0002] In the production of indirect coal liquefaction, the Fischer-Tropsch reactor plays a central role. It is a highly engineered reaction system in which the catalyst is suspended in a slurry bed formed by purified synthesis gas containing CO and H2. These gases are introduced from the bottom of the reactor and react deeply with the catalyst particles. The conditions are strictly controlled at a temperature of about 270°C and a pressure of 2.8MPa to ensure reaction efficiency and product quality. During the reaction, waxy products are formed and accumulated in the slurry bed, and then separated and discharged through the built-in filter tube, while water, light oil and heavy oil escape from the top of the reactor in gaseous form with a small amount of catalyst.

[0003] Next, these high-temperature gaseous products meet the purified synthesis gas at the outlet of the second stage of the compressor and exchange heat in the circulating heat exchanger. This process cools the high-temperature oil and gas, promotes its phase transition, and forms a three-phase mixture of gas, liquid and solid. Among them, liquid heavy oil, gaseous water and light oil, and solid catalyst particles each occupy an important position in the mixture. Subsequently, these three-phase mixtures are directed to the heavy oil separator, which is designed with 204 parallel cyclone separators to efficiently separate various products through centrifugal force.

[0004] During this separation process, light oil and water as gas phase components rise through the riser pipe of the cyclone separator, and then merge into the air cooling unit for further cooling and separation. Heavy oil and catalyst particles as liquid and solid phase components flow along the downcomer to the bottom of the heavy oil separator, and are finally sent to the stripping tower for subsequent processing and product purification.

[0005] However, in actual applications, the heavy oil separator in the related technology is prone to riser breakage under the impact of large feed gas flow. After the riser is damaged, the gas, liquid and solid phases cannot be separated well, resulting in heavy oil carrying water, affecting the quality of intermediate products and further affecting the load of the Fischer-Tropsch unit. Summary of the invention

[0006] The main purpose of the present invention is to provide a heavy oil separator, which can effectively improve the problem of easy breakage of the riser pipe, improve the phenomenon of heavy oil carrying water, improve the quality of intermediate products, and reduce the load of the Fischer-Tropsch device.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In the related art, during the operation of the heavy oil separator, it was found that the heavy oil contained water. When the equipment was opened during maintenance, it was found that part of the cyclone riser was broken. Analysis showed that the inlet gas directly impacted the riser, which may have caused the riser to break. Part of the gaseous water entered the lower part of the cyclone and went to the stripping tower together with the heavy oil, resulting in the heavy oil containing water.

[0028] In order to solve this problem, the inventor took the approach of installing an elliptical baffle at the inlet of the separator, trying to allow the gas to enter the separator from the side, reducing the impact on the cyclone riser in the separator. After the overhaul, it was found that the heavy oil still contained water. When the equipment was turned on, it was found that the cyclone riser was still broken. If the riser breaks, not only will the heavy oil contain water, but it may also cause part of the heavy oil and catalyst to be carried by the gas from the broken riser into the air cooling. The air cooling load increases, affecting the cooling and separation of water and light components. Uncooled water vapor enters the compressor pipeline, which may cause corrosion to the equipment and pipelines. In addition, the increase in the air cooling load also affects the processing capacity of the device. Therefore, the operation of the heavy oil separator has a very important impact on the Fischer-Tropsch device.

[0029] Therefore, in view of the existing problem, the technical staff was organized to analyze again and believed that the rupture of the cyclone riser was mainly caused by the vibration of the air flow impact. According to the GB / T151 fluid induced vibration formula, the vibration was calculated and analyzed:

[0030] Karman vortex frequency fv = st*v / do;

[0031] Turbulence buffeting main frequency ft = v*do / (i*T)*[3.05*(1-do / T) 2 +0.28];

[0032] The natural frequency of the riser is f = 35.3*λ*[E*(do 4 -di 4 ) / (m*I 4 )] 0.5 ;

[0033] do: The outer diameter of the riser is 0.063m;

[0034] di: inner diameter of the riser 0.054m;

[0035] t: riser thickness 0.003m;

[0036] S: The center distance of the riser is 0.19m;

[0037] St: dimensionless, 0.25 from the chart;

[0038] V: cross flow velocity 25m / s;

[0039] i: The longitudinal distance between the centres of the risers is 0.165m;

[0040] T: The center distance of the horizontal heat exchange tube is 0.19m;

[0041] I: span 2.27m;

[0042] E: Material elastic modulus 196000MPa;

[0043] m: Mass per unit length of the riser: 4.25 kg / m;

[0044] λ: frequency constant 22.396;

[0045] After calculation, we get: fv = 99.21;

[0046] ft = 82.52;

[0047] f = 88.74;

[0048] fv / f=1.12>0.5;

[0049] ft / f=0.93>0.5.

[0050] It can be seen that the ratio of the Karman vortex frequency fv to the natural frequency f of the riser is greater than 0.5, and the ratio of the turbulent buffeting main frequency ft to the natural frequency f of the riser is greater than 0.5. In this case, resonance will occur and the riser is prone to breakage. Only by preventing the riser from resonating can the breakage be avoided. Increasing the denominator of the ratio, that is, increasing the natural frequency f of the riser, is a solution to prevent resonance. From the on-site analysis, changing the span of the riser is a simple solution that conforms to theoretical calculation and analysis.

[0051] Therefore, in order to solve the above problems, Figures 1 to 3 As shown, according to an embodiment of the present invention, the heavy oil separator includes: a shell 1, having an inlet 11, a liquid phase outlet 12 and a gas phase outlet 13, the shell 1 has a gas phase gathering area 14, a separation area 15 and a liquid phase gathering area 16, the gas phase gathering area 14 is connected to the gas phase outlet 13, the liquid phase gathering area 16 is connected to the liquid phase outlet 12, and the separation area 15 is located between the gas phase gathering area 14 and the liquid phase gathering area 16; a cyclone 2, arranged in the separation area 15, the cyclone 2 includes a riser 21 and a downcomer 22, a plurality of cyclones 2 are arranged in parallel, and a reinforcement structure 3 is arranged in the region of 1 / 3L to 2 / 3L of the riser 21 along the height direction, the reinforcement structure 3 is fixedly connected to the riser 21, and the span of the riser 21 is adjusted.

[0052] The heavy oil separator has modified the riser 21, and a reinforcement structure 3 is set in the area from 1 / 3L to 2 / 3L in the height direction of the riser 21. The reinforcement structure 3 is fixedly connected to the riser 21 to adjust the span of the riser 21, so as to achieve the purpose of adjusting the natural frequency of the riser 21. Through the above-mentioned method, the riser 21 is transversely reinforced, the span of the riser 21 is shortened, and the natural frequency of the riser 21 is changed, thereby avoiding the resonance phenomenon, effectively improving the problem of fracture and damage of the riser 21 due to resonance, ensuring the separation effect of the heavy oil separator, improving the phenomenon of heavy oil carrying water, improving the quality of intermediate products, and reducing the load of the Fischer-Tropsch device.

[0053] A cyclone 2 is installed in the separator, and the cyclone 2 includes a riser 21 and a downcomer 22. Multiple cyclones 2 are arranged in parallel, which can improve separation efficiency and stability and enhance processing capacity. A reinforcement structure 3 is added to the riser 21 in the area from 1 / 3L to 2 / 3L along its height direction. The reinforcement structure 3 is firmly connected to the riser 21, and its function is to adjust the effective span of the riser 21, prevent vibration and breakage, and ensure the normal operation of the separator.

[0054] Through the above design, the reinforcement structure 3 can effectively reduce the vibration of the riser 21 under the impact of high-temperature oil and gas at the outlet of the Fischer-Tropsch reactor, avoid damage to the riser due to resonance, and thus ensure good separation of heavy oil from the gas phase and solid phase, improve the processing efficiency and product quality of the Fischer-Tropsch device, and reduce potential economic losses caused by equipment failure. The introduction of the reinforcement structure 3 not only solves the stability problem of the riser 21, but also simplifies maintenance work, extends the service life of the equipment, and has a significant effect on the reliability and economy of the overall operation of the lifting device.

[0055] In one embodiment, the high-temperature oil and gas coming out of the top of the Fischer-Tropsch reactor passes through a heat exchanger and then enters a heavy oil separator. 204 cyclones 2 are connected in parallel in the heavy oil separator. The gas phase enters the top of the heavy oil separator from the riser 21 of the cyclone 2, and the liquid phase and the solid phase enter the bottom of the heavy oil separator from the downcomer 22 of the cyclone 2.

[0056] In one embodiment, the reinforcement structure 3 is fixedly connected to the inner wall of the shell 1 and is simultaneously connected to a plurality of riser pipes 21 .

[0057] In this embodiment, the reinforcement structure 3 is fixedly connected to the inner wall of the shell 1 and is simultaneously connected to a plurality of riser pipes 21, which brings about a significant effect of improving stability and structural strength. This design enables the reinforcement structure 3 to effectively disperse and absorb the vibration energy transmitted by the riser pipes 21, and transmit the vibration energy to the entire shell structure through direct connection with the shell 1, and utilize the rigidity of the shell 1 to resist vibration, thereby significantly reducing the resonance phenomenon and potential damage risk of the riser pipes 21 under operating conditions.

[0058] The reinforcement structure 3 is connected to multiple risers 21 at the same time, which can provide an overall support network, so that all the risers 21 are interdependent in structure, which increases the rigidity of the entire riser 21 cluster and reduces the possibility of damage to a single riser 21 due to local stress concentration. Through the fixed connection between the reinforcement structure 3 and the inner wall of the shell 1 and the support of multiple risers 21, not only the operating stability of the heavy oil separator is improved, but also its ability to cope with high flow rate, high temperature and high pressure conditions is enhanced, ensuring the long-term and efficient operation of the separator in the Fischer-Tropsch reaction system, avoiding the problem of heavy oil carrying water due to equipment failure, and improving the quality of the product and the processing capacity of the device.

[0059] In one embodiment, the reinforcement structure 3 includes a connecting rod 31 and a connecting member 32 , the connecting member 32 is fixedly connected to the riser 21 , the connecting rod 31 is fixedly connected to the connecting member 32 , and the fixed end of the connecting rod 31 is fixedly connected to the inside of the shell 1 .

[0060] The fixed connection between the connector 32 and the riser 21, and the fixation between the connecting rod 31, the connector 32 and the shell 1, form a reliable support system, which can significantly improve the stability of the riser 21 and reduce its vibration amplitude under operating conditions. Especially in the Fischer-Tropsch reaction system, under the conditions of high temperature, high pressure and high flow rate, the reinforcement structure 3 can effectively prevent the resonance of the riser 21 caused by the impact of the air flow, avoid the riser 21 from breaking, and thus ensure the efficient and stable operation of the heavy oil separator. The fixed connection between the connecting rod 31 and the inside of the shell 1 allows the reinforcement structure 3 to be used as a part of the shell 1, which enhances the structural integrity and rigidity of the entire device.

[0061] In one embodiment, the connecting member 32 includes an angle iron, which is fixed to the riser 21 by welding, and the connecting rod 31 is detachably connected to the angle iron.

[0062] The angle iron is used as a connecting piece 32, and has good rigidity and strength. It can effectively support the riser 21 and reduce its vibration under the impact of airflow. Especially in the Fischer-Tropsch reaction system, this supporting structure can effectively resist the stress on the riser 21 under high temperature, high pressure and high flow rate conditions, prevent it from resonating due to vibration, and thus avoid damage to the riser 21.

[0063] The detachable connection design between the connecting rod 31 and the angle iron makes it more convenient and quick to maintain the equipment or replace the connecting part 32. This design allows the damaged angle iron or connecting rod 31 to be replaced separately without destroying the entire reinforcement structure 3 or the riser 21, thereby reducing maintenance time and cost and improving equipment availability and operating efficiency.

[0064] Angle iron is a common building material with relatively low cost and mature and easy-to-implement welding technology. By welding and fixing the angle iron to the riser 21, the implementation cost of the reinforcement structure 3 is controlled within a reasonable range.

[0065] In one embodiment, the reinforcement structure 3 is a mesh structure.

[0066] The multiple connecting rods 31 and connecting parts 32 in the mesh structure interact with each other to form a network that can absorb and disperse vibration energy. Through this design, the reinforcement structure 3 can better resist the impact of airflow under high temperature and high pressure conditions in the Fischer-Tropsch reaction system, avoid resonance of the riser 21 and reduce damage.

[0067] The mesh structure improves the rigidity of the entire reinforcement system through dense connections, so that the riser 21 can maintain good shape and position stability even under high flow rate conditions.

[0068] In one embodiment, a reinforcement structure 3 is provided in the region of 0.4L to 0.6L in the height direction of the riser 21 .

[0069] According to the theory of fluid-induced vibration, the natural frequency of the riser 21 is closely related to the Karman vortex frequency and turbulent buffeting frequency it is subjected to. Providing the reinforcement structure 3 in a specific area can change the effective span of the riser 21, thereby adjusting its natural frequency to avoid matching the vibration frequency caused by the fluid and reduce the occurrence of resonance.

[0070] The reinforcement structure 3 is located in the middle area of ​​the riser 21, which is usually subject to greater impact from the airflow. The reinforcement measures can provide additional support and stability here, effectively reduce the vibration caused by the airflow, enhance the structural rigidity of the riser 21, and ensure its stable operation under the high temperature and high pressure working environment of the Fischer-Tropsch reactor.

[0071] In one embodiment, the reinforcement process of the riser 21 is as follows:

[0072] The span between the upper and lower parts of the DN50 riser is 2270mm, which looks slender in the separator. Although an elliptical baffle was added at the gas inlet in 2020, it was still impacted by the airflow, vibrated and broke. Therefore, the following measures were taken to retain the elliptical baffle at the separator inlet and reinforce the baffle with ribs. In addition, angle irons were used for welding reinforcement at a height of 1270mm for the riser 21, and each reinforced angle iron was connected to form an overall reinforcement. In this way, the span of the riser 21 was reduced from a maximum of 2270mm to a maximum of 1270mm, and the above formula was recalculated as follows:

[0073] The natural frequency of the ascending pipe is f = 283.5;

[0074] The Karman vortex frequency remains unchanged at fv = 99.21;

[0075] The main frequency of turbulent buffeting remains unchanged at ft = 82.52;

[0076] The ratios of the two are: fv / f=0.35<0.5;

[0077] ft / f=0.29<0.5.

[0078] Calculations show that the ratios of the Karman vortex frequency and the main frequency of turbulent buffeting to the natural frequency of the riser are both less than 0.5, and the riser will not resonate under the same operating conditions, and thus will not break. During the subsequent overhaul, the riser was reinforced in this way. After the overhaul, the unit was put into operation, and no heavy oil with water was found in the operating data. After the overhaul, the Fischer-Tropsch unit operated stably, and the load reached 101%, which effectively avoided the risk of damage to the riser 21 due to resonance.

[0079] In one embodiment, the connecting member 32 is wrapped around the riser 21 and clamps the riser 21 , and a buffer pad is provided between the connecting member 32 and the riser 21 .

[0080] In this embodiment, the connecting piece 32 is, for example, a half sleeve, which is sleeved outside the riser 21 and is cushioned by a cushion pad. This can avoid damage to the riser 21 when the connecting piece 32 is fixedly connected to the riser 21 and protect the riser 21. When the riser 21 is impacted by the airflow, the cushion pad can be used to offset the impact of the airflow on the riser 21, thereby effectively preventing the riser 21 from being broken and damaged due to the impact of the airflow.

[0081] In one embodiment, a baffle 4 is disposed in the area between the inlet 11 and the cyclone 2 , and the baffle 4 is disposed directly opposite to the inlet 11 .

[0082] By setting the baffle, the gas entering from the inlet 11 can be blocked, so that the gas directly impacts the baffle 4, and after impacting the baffle 4, the gas is disturbed from the peripheral side of the baffle 4, the flow velocity of the airflow after being blocked and decelerated is reduced, and the impact effect is greatly reduced. In the process of flowing to the riser 21, the impact force is greatly reduced, which can effectively reduce the impact effect on the riser 21, protect the riser 21, and avoid the airflow from directly impacting the riser 21. The baffle is, for example, elliptical, and can also be other structures. In one embodiment, the shape of the baffle is adapted to the shape of the longitudinal cross-section of the separator, and a flow passage is formed on the peripheral side.

[0083] In one embodiment, a reinforcing rib is provided on the side of the baffle 4 away from the inlet 11. By providing the reinforcing rib on the side of the baffle 4 away from the inlet 11, it is possible to avoid the reinforcing rib from hindering the flow of the airflow and ensure the flow of the airflow, and it is also possible to strengthen the structure of the baffle 4, improve the structural strength of the baffle 4, and improve the structural stability and reliability of the baffle 4.

[0084] In one embodiment, there are at least two baffles 4, at least two baffles 4 are spaced apart along the airflow entry direction of the inlet 11, and at least two baffles 4 are staggered along the direction perpendicular to the inlet to form an S-shaped baffle structure.

[0085] By arranging baffles 4 at intervals along the direction of air flow entry and staggering them in a direction perpendicular to the inlet to form an S-shaped deflection structure, the air flow entering the heavy oil separator can be effectively dispersed and uniformed. This structure can prevent the air flow from directly and concentratedly impacting the riser 21, but instead guide it evenly to the entire separator space, ensuring that the air flow distribution in the cyclone area is more uniform, thereby improving the separation efficiency.

[0086] The S-shaped deflection structure forces the airflow to change direction multiple times when entering the separator, thereby slowing down the airflow speed. Reducing the airflow speed helps to reduce the impact force on the riser 21, thereby reducing the vibration amplitude and reducing the risk of structural damage caused by airflow impact.

[0087] The S-shaped baffle design of the baffle 4 increases the complexity of the airflow path, and by introducing multiple inflection points in the airflow path, a certain vibration damping effect can be achieved. This design can absorb the vibration energy caused by the impact of the airflow, further reduce the vibration risk of the riser 21, and ensure its long-term stable operation.

[0088] The S-shaped baffle structure helps to increase the residence time of the gas-liquid mixture in the separator, making the gas-liquid separation more complete. At the same time, by controlling the airflow direction, it helps to optimize the separation performance of the cyclone and improve the separation effect of heavy oil and water, light oil and catalyst.
