Description

Technical Field

[0001] This invention relates to the field of chemical catalytic reaction equipment technology, specifically to a preparation device and method for a natural gas catalytic enhancer. Background Technology

[0002] Natural gas, as a clean energy source, is widely used in industrial combustion, gas-fired power generation, and catalytic conversion. However, it suffers from low combustion efficiency and insufficient catalytic activity, necessitating the addition of catalytic enhancers to improve performance. Current methods for preparing natural gas catalytic enhancers mostly employ decentralized equipment, requiring multiple machines to complete synthesis, maturation, and filtration steps. This results in significant material transfer losses, long process cycles, and poor product uniformity and stability. Furthermore, traditional processes lack precise temperature, pressure, and feed ratio control, leading to low synthesis efficiency and poor dispersibility of catalytically active components, failing to meet the demands for high-efficiency catalytic enhancement of natural gas. Therefore, there is an urgent need to develop an integrated, automated, and highly stable preparation equipment and method.

[0003] The existing technology relates to a process and equipment for preparing catalytic enhancers for welding and cutting liquefied natural gas (LNG), application number CN202310720732.7. It includes a reaction vessel, a feeding pipe, and a supernatant suction module. The feeding pipe is connected to the reaction vessel, and the supernatant suction module penetrates the outer wall of the reaction vessel. The supernatant suction module includes a drive assembly, a U-shaped rod, a peristaltic pump, a delivery pipe, a fixing frame, and a waste liquid tank. The drive assembly is fixedly connected to the reaction vessel and located on the outer wall of the reaction vessel. The U-shaped rod penetrates the reaction vessel, with one end fixedly connected to the drive assembly and the fixing frame fixedly connected to the other end of the U-shaped rod. The peristaltic pump is located on the outer wall of the reaction vessel. One end of the delivery pipe is connected to the input end of the peristaltic pump, and the other end is connected to the fixing frame. The waste liquid tank is connected to the output end of the peristaltic pump. This facilitates the suction of the supernatant, improving the preparation efficiency of the catalytic enhancer for welding and cutting LNG.

[0004] However, existing technologies, especially this particular solution, still have the following problems: Using only a single reactor as the core processing vessel, without a main and auxiliary tank circulation path design, maturation and filtration need to be carried out independently in separate steps. The material is in a static maturation state, which is prone to stratification and agglomeration of active components. Furthermore, impurities cannot be intercepted in real time and can only be removed by subsequent supernatant absorption. The impurities are not completely removed, affecting the uniformity of the product.

[0005] Lacking an integrated structure for vacuum degassing and precision filtration, it can only separate some impurities through the supernatant absorption module, which cannot solve the problem of residual bubbles in the material. After bubbles encapsulate impurities or active components, it will cause gas blockage, combustion or uneven catalytic efficiency when the synergist is used, resulting in poor product performance stability.

[0006] Without a dynamic circulation processing mechanism, the mixing of materials in a single reactor relies on its own stirring, which can easily lead to uneven local concentrations and incomplete reactions. Furthermore, the materials can be processed without being transferred, making it impossible to enhance the synergistic effect of ripening and impurity removal through a dynamic flow field, thus limiting the preparation efficiency. Summary of the Invention

[0013] Preferably, the precision filtration component adopts a filter cartridge or filter screen structure and is arranged coaxially with the circulation channel of the maturation filter tank to achieve synchronous precision filtration during the material circulation maturation process and intercept reaction by-products and agglomerated particles in real time.

Detailed Implementation

[0022] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0023] The invention provides, for example Figures 1 to 3 As shown, an apparatus for preparing a natural gas catalyst enhancer includes: The catalytic synthesis main reactor 11 and the maturation filter tank 12 are connected. The circulation outlet of the catalytic synthesis main reactor 11 is connected to the circulation inlet of the maturation filter tank 12, and the circulation outlet of the maturation filter tank 12 is connected to the circulation inlet of the catalytic synthesis main reactor 11. A precision filter assembly 13 is installed between the pipeline of the catalytic synthesis main vessel 11 and the aging filter tank 12. The catalytic synthesis main vessel 11 and the aging filter tank 12 are filtered simultaneously during the cyclic catalysis and aging process, forming an online cyclic aging and filtration coupling flow path between the main and auxiliary tanks. The precision filtration component 13 is located on the material flow channel inside the aging filter tank 12. The vacuum interface of the aging filter tank 12 is connected to the vacuum degassing component 14, so that vacuum degassing and precision filtration are integrated in the aging filter tank 12.

[0024] To overcome the limitations of traditional natural gas catalytic converter preparation processes that involve separate steps for maturation and filtration, and separate degassing and filtration, this solution establishes a core process architecture that couples online maturation and filtration between main and auxiliary tanks. Simultaneously, it enables integrated vacuum degassing and precision filtration within the maturation and filtration tank 12, fundamentally addressing industry pain points such as easy stratification during static maturation, difficulty in removing residual impurities, and the impact of air bubbles on product performance.

[0025] Working principle: Based on the circulation flow path constructed by the catalytic synthesis main reactor 11 and the aging filter tank 12, when the material circulates between the two tanks, it is simultaneously filtered by the precision filter component 13 located in the flow channel of the aging filter tank 12, forming a dynamic processing mode that couples aging and filtration; at the same time, relying on the vacuum degassing component 14 connected to the aging filter tank 12, vacuum degassing and precision filtration are carried out simultaneously in the same tank, achieving process linkage and functional integration.

[0026] Breaking away from the limitations of traditional step-by-step processing, it achieves synergistic linkage between curing and filtration, degassing and filtration, simplifying process steps; the cyclic coupling mode avoids the drawbacks of static curing, and real-time filtration can promptly intercept impurities and improve material uniformity; single-tank integrated processing reduces material transfer, lowers the risk of secondary introduction of impurities and bubbles, and ensures product performance.

[0027] To prevent backflow of materials during the circulation process between the main and auxiliary tanks, and to ensure the dynamic stability of the cyclic ripening and filtration stages, this solution utilizes the linkage between a check valve and a circulation pump to form a unidirectional closed-loop circulation path between the catalytic synthesis main reactor 11 and the ripening and filtration tank 12. This ensures that the materials always flow in an orderly manner in a preset direction, preventing turbulence from interfering with the process effect. A check valve and a circulation pump are installed between the pipelines of the catalytic synthesis main reactor 11 and the ripening and filtration tank 12. The check valve and circulation pump are linked to form a unidirectional closed-loop circulation path between the catalytic synthesis main reactor 11 and the ripening and filtration tank 12, preventing backflow of materials and ensuring the dynamic stability of the cyclic ripening and filtration stages. The raw material feed port of the catalytic synthesis main reactor 11 is connected to a raw material feed pipe 15, and the auxiliary material feed port of the ripening and filtration tank 12 is connected to an auxiliary material feed pipe 19. The finished product discharge ports of the catalytic synthesis main reactor 11 and the ripening and filtration tank 12 are respectively connected to finished product discharge pipes 16.

[0028] Specifically, to ensure the precision of the catalytic synthesis reaction ratio from the source, this solution relies on the raw material feed pipe 15 to achieve precise delivery of catalytically active components, nanocarriers, and dispersants, controlling the raw material metering error within ±0.5% to avoid poor activity and dispersibility of catalytically active intermediates due to ratio deviations. The raw material feed pipe 15 is used to precisely deliver the catalytically active components, nanocarriers, and dispersants into the catalytic synthesis main reactor 11, with a raw material metering accuracy of ±0.5%, ensuring the ratio stability of the catalytic synthesis reaction.

[0029] To achieve precise addition of auxiliary materials during the simultaneous vacuum degassing and precision filtration process, this solution is equipped with a metering valve 110 and a delivery pump 111 on the auxiliary material feed pipe 19. With a metering accuracy of ±0.5%, the pH adjuster and stabilizer are precisely delivered into the maturation filter tank 12, achieving simultaneous completion of degassing, impurity removal and pH adjustment, reducing the need for separate pH adjustment steps.

[0030] The auxiliary material feed pipe 19 is equipped with a metering valve 110 and a delivery pump 111. The auxiliary material is delivered by the delivery pump 111 and enters the maturation filter tank 12 through the auxiliary material feed pipe 19 and the metering valve 110. The metering accuracy of the metering valve 110 is ±0.5%. It is used to accurately add pH adjuster and / or stabilizer into the maturation filter tank 12 during the integrated vacuum degassing and precision filtration process, so as to achieve simultaneous completion of degassing, impurity removal and pH adjustment.

[0031] Specifically, to achieve simultaneous and precise impurity removal during the material recycling and maturation process, this solution uses a filter cartridge or filter screen precision filter assembly 13 with a precision of 0.1-0.5μm, and arranges it coaxially with the circulation channel of the maturation filter tank 12, so that reaction byproducts and agglomerated particles are intercepted in real time at the initial stage of generation, avoiding the difficulty in removing impurities after they combine with active components.

[0032] The precision filter component 13 has a filtration accuracy of 0.1-0.5μm, adopts a filter cartridge or filter screen structure, and is arranged coaxially with the circulation channel of the maturation filter tank 12 to realize synchronous precision filtration during the material circulation maturation process, and intercept reaction by-products and agglomerated particles in real time.

[0033] Furthermore, to achieve efficient vacuum degassing of materials, this solution utilizes a vacuum pump and a vacuum buffer tank to stably regulate the vacuum level within the curing filter tank 12 within a certain range. The negative pressure environment allows tiny bubbles in the material to quickly precipitate, resolving the issues of residual bubbles causing gas blockage and uneven combustion during the use of the synergist. The vacuum degassing component 14 includes a vacuum pump and a vacuum buffer tank. The vacuum buffer tank is connected to the vacuum interface of the curing filter tank 12 via a vacuum pipeline, enabling the vacuum level within the curing filter tank 12 to be adjusted to -0.08MPa to -0.09MPa, thus achieving efficient vacuum degassing of the material.

[0034] To avoid uneven material concentration and localized sedimentation inside the catalytic synthesis main reactor 11 and the maturation filter tank 12, this design incorporates self-circulating pipes between the top and bottom of both tanks. This allows for autonomous circulation of materials within the tanks, further enhancing the uniformity of the catalytic synthesis reaction and the adequacy of dynamic maturation. A circulation pipe 17 is installed between the top and bottom of the catalytic synthesis main reactor 11 to achieve self-circulation and uniform distribution of materials within the reactor. Similarly, a circulation pipe 18 is installed between the top and bottom of the maturation filter tank 12 to achieve self-circulation and uniform distribution of materials within the tank.

[0035] To achieve modular integrated installation of the equipment and provide precise temperature control for core processes, this solution adopts an integrated equipment frame 112 to carry the main and auxiliary tanks. Both tanks are equipped with jacketed temperature control structures with a temperature control accuracy of ±1℃, respectively adapting to the process temperature requirements of catalytic synthesis (30-150℃, preferably 80±5℃) and dynamic maturation (30-100℃, preferably 60±3℃). The equipment frame 112 is used to install the catalytic synthesis main reactor 11 and the maturation filter tank 12. Both the catalytic synthesis main reactor 11 and the maturation filter tank 12 are equipped with jacketed temperature control structures with a temperature control accuracy of ±1℃. The temperature control range of the catalytic synthesis main reactor 11 is 30-150℃, preferably 80±5℃; the temperature control range of the maturation filter tank 12 is 30-100℃, preferably 60±3℃, respectively adapting to the process temperature requirements of catalytic synthesis and dynamic maturation.

[0036] This solution transforms the structural design of the equipment into a feasible industrialized preparation process. It proposes a complete process from raw material metering to finished product filling. Relying on the core advantages of main and auxiliary tank circulation coupling and integrated defoaming filtration, it achieves efficient, stable, and automated preparation of natural gas catalytic enhancers, ensuring that product quality and production efficiency are improved simultaneously.

[0037] This invention also provides a method for preparing a natural gas catalytic enhancer, based on the aforementioned equipment for preparing a natural gas catalytic enhancer, comprising the following steps: S1. Precise metering of raw materials: The catalytic active components, nanocarriers, and dispersants are precisely delivered to the catalytic synthesis main reactor 11 according to a preset mass ratio through the raw material feed pipe 15, metering valve 110, and delivery pump 111. S2. Catalytic synthesis reaction: Start the stirring device and jacket temperature control structure of the catalytic synthesis main reactor 11, heat the material in the reactor to 80±5℃, control the pressure in the reactor to 0.2±0.05MPa, and carry out the coordination complexation reaction for 2-4 hours to form a catalytically active intermediate. S3. Online Circulation and Filtration of Main and Auxiliary Tanks: Open the metering valves 110 and the delivery pump 111 of the circulation pipeline 17 and circulation pipeline 2 to transport the catalytically active intermediate in the catalytic synthesis main reactor 11 to the aging and filtration tank 12. The material is kept at a constant temperature of 60±3℃ by the jacket temperature control structure of the aging and filtration tank 12. After the material is filtered and impurities are removed by the precision filter component 13, it is returned to the catalytic synthesis main reactor 11 through the circulation pipeline 2 18. The cycle is repeated 2-3 times to complete dynamic aging and deep impurity removal. S4. Integrated Vacuum Degassing and Precision Filtration: Close the circulation pipeline, start the vacuum degassing component 14, adjust the vacuum degree in the maturation filter tank 12 to -0.08MPa~-0.09MPa, perform vacuum degassing for 20-40 minutes, while the precision filter component 13 continuously filters and removes impurities; add pH adjuster to the maturation filter tank 12 through the auxiliary material feed pipe 19 and metering valve 110 to adjust the pH of the material to 7.0±0.5; S5. Finished product discharge and filling: After secondary filtration by the 0.22μm precision filter unit of the finished product discharge pipe 16, the processed material is transported to the filling equipment to complete the preparation of natural gas catalyst enhancer.

[0038] In summary, the present invention also has the following combined effects: The catalytic synthesis main vessel 11 and the aging filter tank 12 form a closed-loop flow path through the circulation pipeline. During the circulation process, the precision filter component 13 simultaneously intercepts impurities, realizing the coupling of dynamic aging and real-time filtration. The aging filter tank 12 is connected to the vacuum degassing component 14, which simultaneously completes degassing and filtration under negative pressure, forming an integrated processing mode.

[0039] The check valve and the circulating pump work together to form a one-way closed-loop flow path to prevent material backflow and ensure the dynamic stability of the circulation process. The raw material feed pipe 15 and the auxiliary material feed pipe 19 work together with the metering valve 110 and the conveying pump 111 to achieve precise delivery of raw materials and auxiliary materials. The finished product discharge pipe 16 completes the output of the finished product.

[0040] The circulating pipeline 17 and circulating pipeline 2 18 respectively realize the self-circulation of materials in the main vessel and the maturation tank, avoiding uneven concentration and local precipitation in the tank; the integrated equipment frame 112 integrates the main and auxiliary tanks, and the jacket temperature control structure is adapted to the temperature requirements of catalytic synthesis (80±5℃) and dynamic maturation (60±3℃) with an accuracy of ±1℃.

[0041] Based on the equipment structure, the entire process of preparing natural gas catalytic enhancers is automated by following the steps of "precise metering of raw materials, catalytic synthesis reaction, circulation maturation and filtration of main and auxiliary tanks, integration of vacuum degassing and precision filtration, and finished product discharge and filling".

[0042] Breaking through the limitations of traditional processes: Addressing industry pain points such as easy stratification during static curing, difficulty in removing residual impurities, and the impact of air bubble encapsulation on product performance, this innovative process achieves coupled curing and filtration, and integrated degassing and filtration. Ensuring process stability: A unidirectional closed-loop flow path prevents material backflow, and in-tank self-circulation avoids uneven material concentration and localized sedimentation, ensuring dynamic stability of circulating curing and filtration. Improving proportioning and processing accuracy: Raw material and auxiliary material metering accuracy reaches ±0.5%, ensuring stable proportions for catalytic synthesis reactions from the source; 0.1μm-0.5μm precision filtration removes impurities in real time, and a vacuum of -0.089MPa to -0.09MPa achieves efficient degassing; degassing, impurity removal, and pH adjustment are completed simultaneously, reducing process steps. Optimizing product and production efficiency: Finished products undergo a 0.22μm secondary filtration to improve purity and avoid air resistance and uneven combustion caused by residual air bubbles; an integrated frame enables modular integration, simplifying material conveying processes, and fully automated preparation simultaneously improves product quality and production efficiency.
