Description

Technical Field

[0001] The invention relates to the technical field of hydroprocessing, in particular to a process for hydro-modifying naphtha. Background Art

[0002] Naphtha is one of the petroleum products, also known as chemical light oil and crude gasoline. It is a light oil used as chemical raw material produced by processing crude oil or other raw materials. It is mainly used as chemical raw material. Hydrotreating is one of the most important refining methods for petroleum products. It refers to the process of converting harmful impurities such as sulfur, oxygen, and nitrogen in oil products into corresponding hydrogen sulfide, water, and ammonia under hydrogen pressure and catalyst to remove them, and hydrogenating saturated olefins and diolefins, and partially hydrogenating saturated aromatics to improve the quality of oil products. The process flow of hydrogenation refining of various oil products is basically the same. After the raw oil is mixed with hydrogen, it is sent to a heating furnace to be heated to a specified temperature, and then enters a reactor equipped with a granular catalyst. After the reaction is completed, the hydrogen is separated in the separator and recycled through a compressor. However, during the reforming reaction, there will be naphtha. The oil droplets are mixed in the hydrogen in the form of mist. When they are collected and recycled, the naphtha droplets are easy to damage the compressor. Therefore, a Chinese patent discloses a gas separation device for chemical petroleum refining, with the application number 202210541706.3. When the airflow enters the interior of the separator body to form a spiral airflow, the airflow will push the contact plate inside the separator body to slide along the inner wall of the separator body, so that the contact plate pushes the droplets on the inner wall of the separator body together, so that the droplets accumulate together with greater gravity, increase the speed at which the droplets slide downward, and prevent the droplets from being scattered on the inner wall and causing insufficient gravity. In addition, the droplets have a certain viscosity, so that the downward sliding speed of the droplets is very slow, resulting in a long gas-liquid separation time; However, it is currently inconvenient to discharge the hydrogen after separation, resulting in part of the mixed gas being directly discharged during the treatment process. In addition, the equipment used for the separation process has a complex structure and a single structural function. Different structures are required to achieve separation and push the separated oil to slide, and the operation steps are complicated. Therefore, the present invention provides a naphtha hydrogenation and reforming processing process to meet people's needs. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use: 1. An efficient separation mechanism is provided, which uses a driving motor to drive the rotating cylinder and the stirring plate to rotate inside the separation cylinder, stirs the mixed gas of the reformed hydrogen and naphtha droplets entering the separation cylinder, and uses the centrifugal force generated by the stirring to throw the naphtha mixed in the gas to the inner wall of the separation cylinder, so as to achieve the mutual separation of gas and liquid, so that hydrogen can be recycled, and prevents the naphtha droplets from mixing in the hydrogen and causing damage to the compressor and other mechanisms during the circulation process. The centrifugal force of the stirring will not affect the hydrogen, and it can be directly discharged upward; At the same time, the two stirring plates can be pushed to move by the two-way telescopic rod, and the position of the stirring plates can be adjusted according to the processing stage. When the mixed gas is separated, the stirring plates will not fit the inner wall of the separation cylinder. After the separation is completed, the stirring plates are pushed close to the inner wall of the separation cylinder. During the rotation, the naphtha droplets splashed and adhering to the inner wall of the separation cylinder are scraped and gathered, so that the naphtha droplets can gather together to increase their mass, making it more convenient for them to automatically slide down under the action of gravity. The stirring plate realizes the change and adjustment of two states, and also realizes two processing methods. After stirring and separating, it promotes sliding again. It is easy to use and realizes different functions through the same structure to simplify the structure of the equipment.

[0015] 2. Use an electric push rod to drive the piston plate and the positioning cylinder to rise and fall. After the stirring plate moves, adjust the positions of the left positioning hole and the right positioning hole. The positioning cylinder is embedded in the left positioning hole and the right positioning hole to limit and fix the stirring plate. At the same time, the bottom of the stirring plate is movably embedded in the guide groove, which is more stable during the movement and also plays a certain limiting role, so that the stirring plate remains stable during rotation, stirring and scraping, and also relieves the pressure on the two-way telescopic rod.

[0016] 3. The hydraulic lifting rod is used to drive the lifting ring plate and the sealing cylinder to rise and fall, and the adjustment is made according to the mixed gas processing stage. When the mixed gas is stirred and separated, the sealing cylinder is inserted into the through hole, and the lifting ring plate is tightly attached to the top of the fixed circular plate for sealing and splicing to prevent the mixed gas from being discharged directly upward and causing incomplete separation of naphtha. At the same time, after the separation is completed, the hydrogen can be smoothly discharged upward through the through hole, and the control method is simple.

[0017] 4. Use mounting bolts to lock and fix the fitting ring plate and the splicing ring, so that the fixed circular frame and the oil collecting tank are fixed at the bottom of the separation cylinder. Use the oil collecting tank to align with the inner wall of the separation cylinder, so that the separated naphtha droplets gather and slide down and can be collected in the oil collecting tank. The installation and disassembly method is simple, which is convenient for subsequent cleaning.

[0018] 5. A convenient cleaning mechanism is provided. A gas collecting box is used to collect part of the gas discharged from the air inlet pipe, so that the gas enters the gas diversion box from the gas delivery pipe. At the same time, the left inclined exhaust box and the right inclined exhaust box guide the gas so that the gas can be blown obliquely from the exhaust strip holes to the surface of the stirring plate, blowing away the naphtha droplets adhered to the surface when the gas is stirred, which plays a role in promoting sliding and preventing the naphtha from continuously adhering to the surface of the stirring plate and causing pollution; At the same time, the laser receiver and the laser transmitter cooperate with each other to monitor and adjust the positions of the rotating cylinder and the two stirring plates, so that after stopping the rotation, the two stirring plates can be correctly located in the middle position of the bottom of the left inclined exhaust box and the right inclined exhaust box, and the exhaust gas can be smoothly blown to the surface of the stirring plate.

[0019] 6. Use the control valve and booster pump to capture and pressurize part of the discharged hydrogen, and then transport it to the inside of the air outlet box through the connecting air pipe, and use the exhaust hole to blow it to the surface of the laser receiver and laser transmitter, which cleans the surface of the end so that dust will not continue to adhere to the end, preventing dust from accumulating and covering the laser and causing it to be unable to penetrate normally.

[0020] To sum up, the combination of the efficient separation mechanism and the convenient cleaning mechanism has a certain cleaning effect. The naphtha droplets thrown to the inner wall of the separation cylinder are cleaned so that they fall normally. The naphtha on the surface of the stirring plate is blown and pushed so that it falls smoothly, preventing the naphtha from splashing and remaining during the separation process, which may easily cause subsequent cleaning difficulties.

The laser receiver 610 and the laser transmitter 612 cooperate with each other to monitor and adjust the positions of the rotating cylinder 502 and the two stirring plates 506, so that after the rotation stops, the two stirring plates 506 can be correctly located at the middle position of the bottom of the left inclined exhaust box 606 and the right inclined exhaust box 607, and the exhausted gas can be smoothly blown to the surface of the stirring plate 506; An air outlet box 613 is fixedly installed at the top of the separation cylinder 2 at a position on one side of the mounting frame 611, and exhaust holes 614 are equidistantly opened at one end of the air outlet box 613. A branch pipe 615 is fixedly connected to the top of the exhaust pipe 4. A bracket 616 is fixedly installed at one end of the separation cylinder 2 near the exhaust pipe 4, and a control valve 617 is fixedly installed at the bottom of one end of the bracket 616.

The top and bottom ends of the control valve 617 are connected to the booster pump 618 and the branch pipe 615 respectively. The control valve 617 and the booster pump 618 are used to capture and boost the discharged part of the hydrogen gas, and then transport it to the inside of the gas outlet box 613 through the connecting gas pipe 619, and blow it toward the surface of the laser receiver 610 and the laser transmitter 612 through the exhaust hole 614, so as to clean the surface of the end thereof, so that dust will not continue to adhere to the end thereof, and prevent dust from gathering and covering and causing the laser to be unable to penetrate normally.

[0026] The working principle and use process of the present invention are as follows: first, the two-way telescopic rod 508 contracts inward, pulling the two stirring plates 506 to move inward, so that the right positioning hole 510 moves to the bottom of the positioning cylinder 513, and the electric push rod 511 moves downward, pushing the piston plate 512 and the positioning cylinder 513 down, so that the positioning cylinder 513 is inserted into the inside of the right positioning hole 510, which plays a role in positioning and stabilizing the stirring plate 506. At this time, the edge of the stirring plate 506 does not contact the inner wall of the separation cylinder 2, and a certain distance is left between the two. Then, the hydraulic lifting rod 517 extends downward, pushing the lifting ring plate 519 down, so that the sealing cylinder 520 is inserted into the inside of the through hole 522, and the lifting ring plate 519 is tightly attached to the top of the fixed circular plate 521, which plays a sealing role; Next, after hydrogen is added to naphtha for reforming treatment, the hydrogen can be recovered for recycling, and the recovered reaction gas contains not only hydrogen but also naphtha droplets. The recovered mixed gas enters the interior of the separation cylinder 2 through the air inlet pipe 3, and the driving motor 501 drives the rotating cylinder 502 and the stirring plate 506 to rotate continuously, which will drive the discharged mixed gas to rotate together. The centrifugal force generated by the rotation will throw the naphtha droplets in the mixed gas to the inner wall of the separation cylinder 2, thereby achieving a certain separation effect. After the separation is completed, the driving motor 501 drives the rotating cylinder 502 to stop rotating; Then, the hydraulic lifting rod 517 pulls the lifting ring plate 519 upward, so that it is no longer sealed with the fixed circular plate 521, and the hydrogen automatically rises and is discharged from the exhaust pipe 4. After being processed by the compressor, it can be used for the subsequent naphtha hydrogenation and reforming processing. The separated naphtha droplets will slide downward along the inner wall of the separation cylinder 2, and when the stirring plate 506 rotates and stirs, some naphtha adheres to its surface. After the hydrogen is discharged, the hydraulic lifting rod 517 pushes the lifting ring plate 519 down again, and it is sealed with the fixed circular plate 521. The electric push rod 511 pulls the piston plate 512 upward to make the positioning cylinder 513 away from the right positioning hole 5 10. The bidirectional telescopic rod 508 extends forward, pushing the two stirring plates 506 to move, so that the edges of the stirring plates 506 are closely attached to the inner wall of the separation cylinder 2, and the left positioning hole 509 moves to the bottom of the positioning cylinder 513. The electric push rod 511 extends downward, and the positioning cylinder 513 is inserted into the inside of the left positioning hole 509, which plays a role in stabilizing the positioning of the stirring plates 506. The driving motor 501 drives the rotating cylinder 502 and the stirring plates 506 to rotate, which plays a role in gathering the naphtha droplets adhering to the inner wall of the separation cylinder 2, increasing their mass, making it easier for them to automatically fall, and slide along the inner wall of the separation cylinder 2 to the inside of the oil collecting tank 527; After stirring and scraping for a period of time, the driving motor 501 drives the rotating cylinder 502 to gradually slow down the rotation speed. At this time, the laser receiver 610 and the laser transmitter 612 are both started, and the laser receiver 610 rotates together with the rotating cylinder 502. After the laser emitted by the laser transmitter 612 is captured by the laser receiver 610, the driving motor 501 drives the rotating cylinder 502 to stop rotating directly, which plays a role in adjusting the positions of the two stirring plates 506, so that the two stirring plates 506 are respectively located below the two gas diversion boxes 605, and the subsequent mixed gas continues to enter the interior of the separation cylinder 2 through the air inlet pipe 3, and part of the gas enters the interior of the gas collecting box 602 from the air inlet 603, and then The gas is transmitted to the inside of the gas diversion box 605 through the gas delivery pipe 609, and finally discharged from the exhaust strip holes 608 at the bottom of the left inclined exhaust box 606 and the right inclined exhaust box 607, and blown to the surface of the top of the stirring plate 506, which has the effect of blowing, gathering and sliding the naphtha droplets adhering to the surface of the stirring plate 506. At the same time, the positioning cylinder 513 is pulled out of the left positioning hole 509, and the positions of the two stirring plates 506 are adjusted by using the two-way telescopic rod 508 so that they no longer fit the inner wall of the separation cylinder 2, and the stirring and separation process is directly carried out again. The naphtha on the surface of the stirring plate 506 is pushed and gathered, and when rotating and stirring, it will be thrown to the inner wall of the separation cylinder 2, so that it can also slide down and be discharged; After a period of separation operation, when discharging the separated hydrogen, the control valve 617 and the boost pump 618 are opened, so that part of the discharged hydrogen is transported to the inside of the gas outlet box 613 through the branch pipe 615, the control valve 617, the boost pump 618 and the connecting air pipe 619, and the hydrogen is pressurized and discharged outward from the exhaust hole 614, blowing to the surface of the end of the laser receiver 610 and the laser transmitter 612, which has a cleaning effect on the surface and blows away the dust adhering to the surface in the air, so that the end remains clean and prevents it from affecting the normal irradiation of the laser.
