Description

Technical Field

[0001] The invention belongs to the technical field of chemical engineering, and in particular relates to an integrated resin deacidification treatment system and method. Background Art

[0002] Fischer-Tropsch olefin-alkane mixture is mainly produced through the Fischer-Tropsch synthesis process, which is a catalytic chemical reaction process that can convert synthesis gas into liquid hydrocarbon fuels such as gasoline, diesel and wax compounds. However, in addition to these valuable hydrocarbon compounds, the olefin-alkane mixture obtained by the Fischer-Tropsch synthesis may also contain a certain amount of impurities such as organic acids. In order to improve the purity and quality of the product and meet the needs of subsequent processing or application, the Fischer-Tropsch olefin-alkane mixture usually needs to be deacidified to ensure the stability and reliability of the final product.

[0003] The existing treatment system has a relatively complex and cumbersome process for removing organic acids from Fischer-Tropsch alkane mixtures. In particular, when using resin for deacidification, when the resin in the resin tower reaches the treatment upper limit, that is, adsorption saturation, the resin needs to be activated and regenerated. However, during the resin activation period, the deacidification operation cannot be carried out, which causes the deacidification process to be interrupted. This interruption not only slows down the deacidification speed, but also affects the overall deacidification efficiency, making the entire treatment process less smooth and efficient.

[0018] A method for an integrated resin deacidification treatment system comprises the following steps:

[0019] Step 1, filtration of the mixture: the Fischer-Tropsch alkane mixture flows into the interior of the filter element through the water inlet pipe, which can fully filter out the particulate impurities in the Fischer-Tropsch alkane mixture to avoid the situation where the impurities block the pipeline during the deacidification process, and then the filtered mixture can be input into the mixture storage tank through the water outlet pipe;

[0020] Step 2, deacidification of the mixture: the mixture in the mixture storage tank is extracted by a material pump, and then input into the deacidification resin tower through the mixture delivery pipe for deacidification treatment, and the deacidified product is input into the product storage tank through the product pipeline, and by opening and closing the valve on the mixture delivery pipe, the two deacidification resin towers can be used in turn to improve the deacidification efficiency;

[0021] Step 3, activating the resin with alkali solution: extracting the alkali solution in the alkali solution storage tank through the material pump, and then inputting the alkali solution into the deacidification resin tower through the alkali solution delivery pipe, the deacidification resin tower can be activated by the alkali solution, and then the desalted water is input into the deacidification resin tower through the brine nitrogen pipe to soak the resin, and finally the brine nitrogen pipe inputs nitrogen into the deacidification resin tower to dry the resin;

[0022] Step 4, recovery of activation liquid: the alkali liquid used to activate the resin is input into the oil-water separator through the activation liquid pipeline for oil-water separation, the waste oil is input into the waste oil storage tank through the oil pipeline, and the separated dilute alkali liquid flows back to the alkali liquid storage tank through the reflux pipe, and then the solid alkali is added through the alkali adding pipe, and finally the alkali liquid is fully stirred and evenly mixed through the stirring mechanism.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention sets a deacidification mechanism at the top of the base. By starting the material pump connected to the mixture delivery pipe, the mixture is input into a deacidification resin tower to adsorb the organic acid therein. At the same time, the material pump connected to the alkali solution delivery pipe is started, and the alkali solution is input into another deacidification resin tower for resin activation. The two deacidification resin towers can be used for activation in turn, thereby ensuring the continuity of the deacidification operation, significantly improving the deacidification speed and efficiency, and making the entire treatment process smoother and more efficient.

[0025] (2) The present invention sets a recovery mechanism at the top of the base. After the activation liquid is separated into oil and water by the oil-water separator, the separated dilute alkali liquid can flow back into the alkali liquid storage tank, thereby realizing the recovery and reuse of the alkali liquid. Subsequently, solid alkali can be added to the alkali liquid storage tank through the alkali adding pipe. In addition, through the meshing transmission between the driving gear and the gear ring of the driver, the transmission shaft will rotate and fully stir the inner edge of the alkali liquid storage tank. This step effectively improves the quality of the alkali liquid.

[0026] (3) The present invention sets a filtering mechanism at the top of the mixture storage tank, and the Fischer-Tropsch olefin mixture is input into the interior of the filter element with multiple layers of annular filter screens through the water inlet pipe. These multiple layers of annular filter screens filter the material in turn, thereby fully removing the particulate impurities in the Fischer-Tropsch olefin mixture. This not only avoids the situation where impurities block the pipeline in the subsequent deacidification process, but also prevents these particulate impurities from having an adverse effect on the deacidification or subsequent deacidification process.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] See also Figures 1 to 8 As shown, an integrated resin deacidification treatment system comprises:

[0043] Base 1;

[0044] A deacidification mechanism 2 is installed at the middle of the top of the base 1, a recovery mechanism 3 is installed at one side of the top of the base 1, a mixture storage tank 4 is installed at the other side of the top of the base 1, and a filtering mechanism 5 is installed at the middle of the top of the mixture storage tank 4;

[0045] The deacidification mechanism 2 includes a deacidification resin tower 21, a product pipeline 22, a brine pipeline 23, an activation liquid pipeline 24 and a support leg 25. There are two deacidification resin towers 21. The product pipeline 22 is installed between the middle parts of the tops of the two deacidification resin towers 21. The brine pipeline 23 is installed between one side of the tops of the two deacidification resin towers 21. The activation liquid pipeline 24 is installed between the other sides of the tops of the two deacidification resin towers 21. There are eight support legs 25, which are respectively installed around the bottom ends of the two deacidification resin towers 21, and the bottom ends of the eight support legs 25 are all installed on the top of the base 1.

[0046] Depend on Figures 1 to 4 It can be seen that a controller 6 is installed in the middle of the outer wall of the mixture storage tank 4, a desalted water tank 7 and a product storage tank 8 are installed on the recovery mechanism 3, and a discharge pipe 9 is installed at the lower part of the outer wall of the desalted water tank 7 and the lower part of the outer wall of the product storage tank 8;

[0047] An alkali liquid delivery pipe 26 is commonly installed between one side of the bottom ends of the two deacidification resin towers 21, and a mixture delivery pipe 27 is commonly installed between the other sides of the bottom ends of the two deacidification resin towers 21. Material pumps 28 are installed at the other ends of the mixture delivery pipe 27 and the other ends of the alkali liquid delivery pipe 26. The two material pumps 28 are respectively installed at the lower parts of the opposite surfaces of the mixture storage tank 4 and the recovery mechanism 3. A brine nitrogen pipe 29 is commonly installed between the middle parts of the bottom ends of the two deacidification resin towers 21.

[0048] As can be seen from the above, through the operation of the controller 6, the material pump 28 connected to the mixture delivery pipe 27 is first started, and the two valves on the mixture delivery pipe 27 are adjusted to ensure that one is in a closed state and the other is open. The material pump 28 then generates a strong suction force to extract the Fischer-Tropsch alkane mixture in the mixture storage tank 4 and transport it to one of the deacidification resin towers 21 through the mixture delivery pipe 27. In the tower, the alkaline resin can efficiently adsorb the organic acid in the mixture with a removal rate of more than 95%. Subsequently, the deacidified mixture is safely transported to the product storage tank 8 through the product pipeline 22 for proper storage. At the same time, the controller 6 also starts the material pump 28 connected to the alkali solution delivery pipe 26, and adjusts the valve state on the alkali solution delivery pipe 26 accordingly (one is open and the other is closed). The material pump 28 works again to extract the alkali solution in the alkali solution storage tank 31 and transport it to another deacidification resin tower 21. The resin is activated, and the activated alkali solution flows smoothly into the recovery mechanism 3 through the activation solution pipeline 24. After this process is completed, the two ends of the brine nitrogen pipe 29 are connected to the water pipeline and the gas pipeline respectively. After the alkali solution has treated the resin, the corresponding valve on the brine nitrogen pipe 29 is opened in time, and the resin is further soaked with desalted water until the pH value of the desalted water reaches about eight. After that, the used desalted water is returned to the desalted water tank 7 through the brine pipeline 23 for storage. Finally, by closing and reopening the corresponding valve on the brine nitrogen pipe 29, nitrogen is smoothly input into the internal drying resin of the deacidification resin tower 21, thereby completing the activation treatment of the resin. By flexibly adjusting the valve states on the alkali solution delivery pipe 26 and the mixture delivery pipe 27, the two deacidification resin towers 21 can be activated and used alternately, thereby ensuring the continuous deacidification process. This design not only significantly improves the deacidification speed and efficiency, but also makes the entire treatment process smoother and more efficient.

[0049] Specifically, refer to Figures 1 to 4 As shown, the alkali solution delivery pipe 26, the mixture delivery pipe 27, the product pipeline 22, the brine pipeline 23 and the activation liquid pipeline 24 are all configured as Y-shaped shunt pipes, and two valves are provided on the alkali solution delivery pipe 26, the mixture delivery pipe 27, the product pipeline 22, the brine pipeline 23 and the activation liquid pipeline 24. The material pump 28 is electrically connected to the controller 6, the brine nitrogen pipe 29 is configured as an I-shaped shunt pipe, and four valves are provided on the brine nitrogen pipe 29. The interior of the deacidification resin tower 21 is filled with modified alkaline resin.

[0050] As can be seen from the above, it is convenient to adjust the flow direction of the fluid as needed in the process flow. The valve is used to control the opening and closing of the pipeline and adjust the flow rate of the fluid. The material pump 28 can receive the instructions of the controller 6 to work. The I-shaped brine nitrogen pipe 29 can realize the diversion and merging of the fluid. At the same time, the four valves provide more control points. The modified alkaline resin can fully remove the acidic substances in the Fischer-Tropsch alkane mixture.

[0051] Embodiment 2:

[0052] refer to Figures 5 to 7 As shown, the recovery mechanism 3 includes an alkali liquid storage tank 31, an alkali adding pipe 32, a stirring mechanism 33, a waste oil storage tank 34, an oil-water separator 35, an oil delivery pipe 36, a return pipe 37 and a gear ring 38. The alkali liquid storage tank 31 is installed at the top of the base 1, the alkali adding pipe 32 is installed at the upper part of one end of the alkali liquid storage tank 31, the stirring mechanism 33 is installed between the inner walls on both sides of the alkali liquid storage tank 31, the waste oil storage tank 34 is installed at one side of the top of the alkali liquid storage tank 31, the oil-water separator 35 is installed at the top of the waste oil storage tank 34, the oil delivery pipe 36 is installed at the upper part of the outer wall of the oil-water separator 35, the return pipe 37 is installed at the lower part of the outer wall of the oil-water separator 35, and two gear rings 38 are provided, and the two gear rings 38 are respectively installed on the inner walls on both sides of the alkali liquid storage tank 31;

[0053] The stirring mechanism 33 includes a stirring shaft 331, a driver 332, a large stirring paddle 333, a connecting plate 334, a transmission shaft 335, a small stirring paddle 336 and a gear 337. The stirring shaft 331 is installed between the inner walls on both sides of the alkali solution storage tank 31 through a bearing, the driver 332 is installed at one end of the stirring shaft 331, the large stirring paddle 333 is installed on the outer surface of the stirring shaft 331, two connecting plates 334 and two gears 337 are provided, and the two connecting plates 334 are respectively installed on both sides of the outer surface of the stirring shaft 331, the transmission shaft 335 is installed between the lower parts of the opposite surfaces of the two connecting plates 334 through a bearing, the small stirring paddle 336 is installed on the outer surface of the transmission shaft 335, and the two gears 337 are respectively installed at both ends of the transmission shaft 335.

[0054] As can be seen from the above, first, the activation liquid is separated into oil and water by the oil-water separator 35, and the waste oil after separation is transported to the waste oil storage tank 34 for storage via the oil delivery pipe 36, while the separated dilute alkali solution is returned to the alkali solution storage tank 31 via the reflux pipe 37, so that the alkali solution is recovered and reused. Since the concentration of the alkali solution will be reduced after the resin is activated, it needs to be supplemented. At this time, solid alkali can be added to the alkali solution storage tank 31 through the alkali adding pipe 32, and then the driver 332 is started by the controller 6, thereby driving the stirring shaft 331 to rotate, and the stirring The multiple large stirring paddles 333 on the mixing shaft 331 rotate accordingly, fully stirring and mixing the dilute alkali solution and the added solid alkali, and also causing the connecting plate 334 to drive the transmission shaft 335 to rotate. At the same time, through the meshing transmission between the gear 337 and the ring gear 38, the transmission shaft 335 rotates while also driving the multiple small stirring paddles 336 installed thereon to rotate together, so that the internal edge position of the alkali solution storage tank 31 can be thoroughly stirred, effectively avoiding stirring dead corners or missed areas, thereby significantly improving the quality of the alkali solution.

[0055] Preferably, reference Figures 5 to 7 As shown, the driver 332 and the oil-water separator 35 are both electrically connected to the controller 6 , the large stirring paddles 333 and the small stirring paddles 336 are staggered, and the gear 337 is meshed with the corresponding ring gear 38 .

[0056] As can be seen from the above, the driver 332 and the oil-water separator 35 can both receive instructions from the controller 6 to work, and the staggered distribution of the large stirring paddles 333 and the small stirring paddles 336 can more effectively stir the fluid, realize the self-rotation function of the transmission shaft 335, and ensure sufficient mixing of the fluid.

[0057] Embodiment three:

[0058] refer to Figure 8 As shown, the filtering mechanism 5 includes a filter cartridge 51, a water outlet pipe 52, a sealing cover 53, a water inlet pipe 54 and a filter core 55. The filter cartridge 51 is installed at the top end of the mixture storage tank 4. Two water outlet pipes 52 are provided. Both water outlet pipes 52 are installed at the lower part of the outer surface of the filter cartridge 51. The sealing cover 53 is installed at the upper part of the outer surface of the filter cartridge 51. The water inlet pipe 54 is installed at the middle part of the top end of the sealing cover 53. The filter core 55 is installed on the top inner wall of the sealing cover 53.

[0059] As can be seen from the above, before the Fischer-Tropsch alkane mixture is deacidified, it can be input into the filter element 55 equipped with a multi-layer annular filter screen through the water inlet pipe 54. These multi-layer annular filter screens can finely filter the material in turn, thereby ensuring that the filter element 55 can fully remove the particulate impurities in the Fischer-Tropsch alkane mixture. The filtered material flows smoothly into the interior of the filter cylinder 51, and is finally transported to the mixture storage tank 4 through the water outlet pipes 52 on both sides for storage in order to carry out subsequent deacidification treatment. This step not only effectively avoids the situation where impurities may block the pipeline during the subsequent deacidification process, but also prevents these particulate impurities from causing adverse effects on the deacidification or subsequent deacidification process. When the filter element 55 has a poor filtering effect due to long-term use, the filter element 55 can be easily removed and replaced by rotating the sealing cover 53 to ensure that the filter element 55 always maintains a good filtering effect.

[0060] Preferably, reference Figure 8 As shown, the upper outer surface of the filter cartridge 51 and the inner wall of the sealing cover 53 are engraved with spiral patterns, and a through hole is opened in the middle of the top of the filter core 55. The filter core 55 is composed of a plurality of annular filter screens and two mounting plates.

[0061] As can be seen from the above, the spiral pattern is designed to increase the sealing 53 between the filter cartridge 51 and the sealing cover, the through hole allows the fluid to enter the innermost part of the filter element 55, and the multiple annular filters can improve the filtration efficiency and filtration accuracy of the filter element 55, ensuring the purity and quality of the fluid.

[0062] Embodiment 4:

[0063] refer to Figures 1 to 8 As shown, a method for an integrated resin deacidification treatment system comprises the following steps:

[0064] Step 1, filtration of the mixture: the Fischer-Tropsch alkane mixture flows into the interior of the filter element 55 through the water inlet pipe 54, and the particulate impurities in the Fischer-Tropsch alkane mixture can be fully filtered out to avoid the situation where the impurities block the pipeline during the deacidification process, and then the filtered mixture can be input into the mixture storage tank 4 through the water outlet pipe 52;

[0065] Step 2, deacidification of the mixture: the mixture in the mixture storage tank 4 is extracted by the material pump 28, and then input into the deacidification resin tower 21 through the mixture delivery pipe 27 for deacidification treatment, and the deacidified product is input into the product storage tank 8 through the product pipeline 22, and by opening and closing the valve on the mixture delivery pipe 27, the two deacidification resin towers 21 can be used in turn to improve the deacidification efficiency;

[0066] Step 3, activating the resin with alkali solution: extracting the alkali solution in the alkali solution storage tank 31 through the material pump 28, and then inputting the alkali solution into the deacidification resin tower 21 through the alkali solution delivery pipe 26, the deacidification resin tower 21 can be activated with alkali solution, and then inputting the desalted water into the deacidification resin tower 21 through the brine nitrogen pipe 29 to soak the resin, and finally the brine nitrogen pipe 29 inputs nitrogen into the deacidification resin tower 21 to dry the resin;

[0067] Step 4, recovery of activation liquid: the alkali liquid used to activate the resin is input into the oil-water separator 35 through the activation liquid pipeline 24 for oil-water separation, the waste oil is input into the waste oil storage tank 34 through the oil pipeline 36, and the separated dilute alkali liquid flows back to the alkali liquid storage tank 31 through the reflux pipe 37, and then the solid alkali is added through the alkali adding pipe 32, and finally the alkali liquid is fully stirred and uniformly stirred through the stirring mechanism 33.

[0068] Application examples:

[0069] This design is mainly used in the processing of Fischer-Tropsch synthesis products in the chemical industry, especially in the subsequent processing of Fischer-Tropsch olefin-alkane mixtures. Fischer-Tropsch synthesis is a method for synthesizing hydrocarbon compounds through carbon monoxide (CO) and hydrogen (H2) in the presence of a catalyst. Its products include a variety of olefins, alkanes and other compounds. These products need to be further processed to meet specific application requirements. In chemical plants, Fischer-Tropsch olefin-alkane mixtures need to undergo a series of post-processing steps to remove impurities, adjust composition and improve quality. This design pre-treats the Fischer-Tropsch olefin-alkane mixture by setting a filtering mechanism 5 to effectively remove solid impurities and particles therein, thereby preventing these impurities from clogging the subsequent processing process. The pipeline may be blocked or the product quality may be affected. Subsequently, the deacidification resin tower 21 in the deacidification mechanism 2 is used to fully deacidify the Fischer-Tropsch alkane mixture. It is worth noting that the two deacidification resin towers 21 can be activated and used in turn. This design ensures the continuity and efficiency of the deacidification process and significantly improves the deacidification efficiency. Furthermore, the activation liquid generated in the treatment process is separated into oil and water by the recovery mechanism 3, so that the alkali solution is recovered. The recovered alkali solution is fully mixed with the solid alkali through the stirring mechanism 33 to further improve its quality and reuse efficiency. This process of alkali solution recovery and reuse not only reduces the consumption of raw materials, but also reduces the emission of waste, thereby effectively reducing production costs and environmental burdens.
