Description

Technical Field

[0001] The present disclosure relates to the technical field of hydrate promoter regulation and gas separation, and in particular to a hydrate promoter regulation and gas separation method and device, and a gas separation device. Background Art

[0002] H2-CO2 mixed gas is widely derived from industrial tail gas (such as synthetic ammonia purge gas, steelmaking converter gas), biomass fermentation mixed gas, biogas fermentation products, and by-products of water electrolysis hydrogen production process. Exploring its efficient separation method can not only achieve efficient purification of H2, provide clean energy and high-quality raw materials for fuel cells, chemical synthesis and other fields, but also use the separated CO2 for chemical production and geological storage, contributing to the goal of carbon neutrality. In the context of global energy transformation, the surge in H2 demand and the pressure to reduce CO2 emissions coexist. There is an urgent need for separation technologies with high separation efficiency, low energy consumption, and clean and pollution-free to solve the problems of clean energy and resource recycling. Traditional mixed gas separation methods, such as chemical absorption, physical absorption, membrane separation and adsorption separation, have long played a key role in industrial production. However, with the increasing demand for industrial development, the disadvantages of these traditional methods have gradually become prominent. Therefore, there is an urgent need to design an efficient, green and pollution-free H2-CO2 mixed gas separation and purification system and equipment.

[0003] The solutions to this problem in the prior art and the problems with these solutions:

[0004] (1) Chemical adsorption method: Specified chemical reagents are used to react with CO2 to form compounds, while H2 does not react, thereby achieving the separation of mixed gases. Commonly used chemical absorbents include MEA (monoethanolamine) and DEA (diethanolamine), which react with CO2 to form carbamates, and can release CO2 under conditions such as heating or reduced pressure, thereby achieving the regeneration and recycling of the absorbent. The chemical absorption method has a strong absorption capacity and high selectivity for CO2, and can achieve a high carbon capture efficiency. However, the absorbent may react with impurities in the mixed gas, resulting in absorbent loss, requiring regular replenishment, and the absorption and desorption processes consume a lot of energy, resulting in high costs. There are also serious equipment corrosion problems, high requirements for equipment materials, and high maintenance costs.

[0005] (2) Physical absorption method: The separation of CO2 is achieved based on the difference in solubility of each component in the mixed gas in a specific absorbent. Under high pressure and low temperature conditions, the solubility of CO2 in the absorbent increases and is absorbed. When the pressure decreases and the temperature increases, CO2 is desorbed from the absorbent. Commonly used physical absorbents in industry include methanol, polyethylene glycol dimethyl ether, etc. The absorbent in the physical absorption method is not easy to degrade, has good stability, and the desorption process is relatively simple, and the energy consumption is lower than the chemical absorption method. However, the absorption selectivity of CO2 is not as high as that of the chemical absorption method, and the separation efficiency is not high; and in a low concentration CO2 environment, the absorption effect is not good. Not only does the absorbent have certain requirements for equipment, but the equipment investment cost is also high.

[0006] (3) Membrane absorption method: The membrane separation method is a method in which a mixed gas passes through a selectively permeable membrane material under the drive of a pressure difference. Due to the different permeation rates of different gases in the membrane, CO2 and H2 are separated. The membrane separation method has the advantages of simple operation, small equipment footprint, no phase change process, and relatively low energy consumption. However, the cost of membrane materials is high, the service life is limited, the membrane is easily contaminated and damaged, and high gas pretreatment requirements are required, otherwise the membrane separation effect will be affected.

[0007] (4) Adsorption separation method: The adsorption effect of the adsorbent on CO2 in the mixed gas is utilized to adsorb CO2 on the surface of the adsorbent, thereby achieving separation of the mixed gas. After the adsorbent reaches saturation, CO2 is desorbed by changing conditions such as temperature or pressure, thereby achieving recycling of the adsorbent. Commonly used adsorbents in industry include activated carbon, zeolite molecular sieves, metal organic framework materials (MOFs), etc. The adsorption separation method has the advantages of high separation selectivity, adsorbent reuse, simple equipment, and flexible operation. However, the adsorption capacity of the adsorbent is limited, so it is not suitable for large-scale, high-flow gas treatment. In addition, the adsorption and desorption processes require a certain amount of energy, and the regeneration time also affects the overall treatment efficiency.

[0008] (5) Low-temperature distillation: Low-temperature distillation is mainly based on the characteristic that the components of the mixed gas have different boiling points to separate the mixed gas. In a low-temperature environment, the mixed gas is cooled, and the gas with a higher boiling point will first liquefy into a liquid, while the gas with a lower boiling point remains in a gaseous state, thereby achieving gas-liquid separation. Then, through the distillation operation, the liquefied components are heated, so that the impurities with low boiling points are vaporized and separated again, thereby achieving the purpose of gas separation. Low-temperature distillation has the advantages of achieving high-precision separation of multiple gases, high technical maturity, continuous production, high production efficiency, and meeting the needs of large-scale industrial production. However, the entire process needs to be carried out at extremely low temperatures, which requires high refrigeration equipment, huge equipment investment costs, and high requirements for the pretreatment of the raw gas. Otherwise, impurities are easy to freeze at low temperatures, affecting equipment operation.

[0009] Based on the above discussion, it is necessary to target CO2 hydrates and solve the corresponding technical problems of existing carbon capture and storage technologies, such as low CO2 capture efficiency, high requirements for reaction conditions, difficulty in separating mixed gases, and high energy consumption.

[0171] In the embodiment of the present disclosure and other possible embodiments, the hydrate secondary generation tank 2 is connected to the gas heater 10 through a pipeline, the gas heater 10 is connected to the primary membrane separation device 6, and the first retention side 61 of the primary membrane separation device 6 is connected to the hydrate secondary generation tank 2 through the first retention side pipeline 17; the first permeate side 62 of the primary membrane separation device 6 is connected to the gas booster 9 through the first permeate side pipeline, the gas booster 9 is connected to the secondary membrane separation device 5, the second retention side 51 of the secondary membrane separation device 5 is connected to the primary membrane separation device 6 through the second retention side pipeline 18, and the second permeate side 52 of the secondary membrane separation device 5 is connected to the H2 gas storage tank 4.

[0172] In the embodiment of the present disclosure and other possible embodiments, the H2 gas tank 4 and the CO2 gas tank 16 are both located to the right of the water bath tank body 8 and the refrigeration unit 3 as a whole, and the bottoms of the H2 gas tank 4 and the CO2 gas tank 16 are both located at the same horizontal position as the bottom of the refrigeration unit 3; the controller 19 is located in the center of the box body 20, and the controller 19 is connected to the temperature and pressure integrated sensor 13 on the first-level hydrate generation tank 1 and the second-level hydrate generation tank 2; the controller 19 is connected to the safety valve 11 provided on the first-level hydrate generation tank 1 and the second-level hydrate generation tank 2. Once the internal gas of the first-level hydrate generation tank 1 and the second-level hydrate generation tank 2 leaks, the system will promptly remind you to ensure safety detection.

[0173] In the embodiments of the present disclosure and other possible embodiments, the hydrate formation technology only needs to control the temperature, pressure, and the type and concentration of the promoter. Under the conditions corresponding to the first set tank temperature of 2°C or 1-3°C, the third set tank temperature of 2°C or 1-3°C, the first tank set pressure of the first hydrate generation tank 1 of 6MPa, and the third tank set pressure of the second hydrate generation tank 2 of 4.2MPa, both the first hydrate generation tank 1 and the second hydrate generation tank 2 can form CO2 hydrates to achieve the secondary separation effect of CO2 and H2 in the mixed gas. After the secondary hydrate separation in the first hydrate generation tank 1 and the second hydrate generation tank 2, the H2 concentration in the mixed gas output by the second hydrate generation tank 2 reaches 88%, meeting the gas pretreatment standard of the membrane separation device.

[0174] In the embodiment of the present disclosure and other possible embodiments, in order to maximize the hydrate CO2 hydrate separation efficiency, different types and concentrations of promoters are added according to the different mixed gas components and pressures in the first hydrate generation tank 1 and the second hydrate generation tank 2, so as to achieve the best separation effect of CO2 and H2 in the mixed gas; wherein, in the first hydrate generation tank 1, the second set tank temperature is 2°C, the second tank set pressure is 6MPa, and the composition is H2 with a first hydrogen ratio and a first carbon dioxide ratio of 60% of the first hydrogen set ratio and CO2 with a first hydrogen set ratio of 60%, the first hydrate promoter corresponding to the first set concentration range of 4 to 10wt% of CP cyclopentane and a set mass of 0.1 to 1g of Ca(OH)2 calcium hydroxide is added to the first hydrate generation tank 1 to promote the hydrate conversion rate, and the generated CO2 hydrate is separated under the conditions of maintaining the set pressure in the second tank at 6MPa and the first set tank temperature at 2°C;

[0175] In the embodiment of the present disclosure and other possible embodiments, in the secondary hydrate generation tank 2, since the pressure of the mixed gas in the second tank is reduced from the set pressure in the second tank to the set pressure in the first tank of about 4.2 MPa, at the third set tank temperature of 2° C., the second H2 ratio in the mixed gas input from the primary hydrate generation tank 1 to the secondary hydrate generation tank 2 increases from 40% corresponding to the first hydrogen set ratio to 75% of the second hydrogen set ratio, and the second CO2 ratio decreases from 60% of the first carbon dioxide set ratio to 25% of the second carbon dioxide set ratio, CP cyclopentane in a first set concentration range of 4 to 10 wt% and TBAB tetrabutylammonium bromide promoter in a second set concentration range of 4 to 10 wt% are added to promote CO2 hydrate formation to achieve the optimal separation efficiency at this pressure. The entire operation process only requires controlling the temperature, pressure, type and concentration of the promoter, and the operation is simple.

[0176] In the embodiments disclosed herein and other possible embodiments, CO2 hydrate in a gaseous state is a cage-shaped crystalline compound formed by water and CO2 gas under specific temperature and pressure conditions. In the hydrate method carbon capture process, CO2 can form hydrates with water under certain conditions, while other types of gases such as nitrogen and hydrogen are more difficult to form hydrates or have a weaker tendency to form hydrates under the same conditions. By controlling the temperature and pressure of the reaction system and adding suitable promoters, CO2 is preferentially combined with water to form hydrate crystals. These hydrate crystals wrap CO2 in their lattice structure to achieve the purpose of separating CO2 from the mixed gas. When it is necessary to release CO2, the temperature or pressure conditions are changed to decompose the hydrate and release a high concentration of CO2.

[0177] In the embodiment of the present disclosure and other possible embodiments, a mixed gas with a pressure of 6 MPa and a composition of 40% H2 and 60% CO2 is introduced into the first-stage hydrate generation tank 1 to generate first-stage CO2 hydrate. The refrigeration unit is controlled by the controller 19 to ensure that the temperature in the first-stage hydrate generation tank 1 is 1-3°C and the volume of water is 50%.

[0178] The water bath 8 is provided with a water bath coolant having a content of 30% and a density of 1.041×10 3 kg / m 3, a specific heat capacity of 3.66 kJ / kg·k of ethylene glycol aqueous solution at a temperature of 25°C. After the primary hydrate is generated in the primary hydrate generation tank 1, the proportion of H2 in the mixed gas increases from 40% to 75%, and the proportion of CO2 decreases from 60% to 25%. The mixed gas from the reacted primary hydrate generation tank 1 is passed through a pipeline to the secondary hydrate generation tank 2. The pressure of the secondary hydrate generation tank 2 drops to 4.2 MPa and the temperature is 1-3°C. After the reaction, the proportion of H2 in the mixed gas increases from 75% to 88%, the proportion of CO2 decreases from 25% to 12%, and the pressure of the mixed gas drops to 2.5 MPa. The CO2 hydrate in the primary hydrate generation tank 1 and the secondary hydrate generation tank 2 can be passed through a refrigeration unit 3 to raise the temperature to about 20°C for hydrate decomposition, and then passed through a pipeline 7 to the CO2 gas storage tank 16. After testing, it was found that after the separation of CO2 hydrate, the H2 concentration in the CO2 gas was far lower than the H2 concentration corresponding to the explosion limit, so safety was guaranteed.

[0179] The secondary hydrate generation tank 2 is connected to the gas heater 10 through a pipeline. After the mixed gas outputted from the primary hydrate generation tank 1 to the secondary hydrate generation tank body 2 generates secondary hydrates through the secondary hydrate generation tank 2, the H2 concentration in the mixed gas outputted from the secondary hydrate generation tank body 2 is 88%, the CO2 concentration decreases from 25% to 12%, 2°C, and the pressure outputted from the secondary hydrate generation tank body 2 is 2.5MPa. The mixed gas enters the gas heater 10, is heated to a set mixed gas temperature of 50-70°C, and then enters the primary membrane separation device 6 for primary membrane separation. The H2 proportion in the mixed gas on the first retention side 61 of the primary membrane separation device 6 is about 70%, the pressure is about 2.5MPa, 50-70°C, and the mixed gas is passed through the first retention side pipeline 17. The mixed gas on the first permeate side 62 of the primary membrane separation device 6 contains approximately 95% H2, has a pressure of 0.1 MPa, and is pressurized at 50-70°C. The mixed gas enters the gas booster 9 through a pipeline, is pressurized to 2.5 MPa, and is pressurized at 50-70°C, and then enters the secondary membrane separation device 5. The mixed gas on the second retentate side 51 of the secondary membrane separation device 5 contains approximately 85%-92% H2, has a pressure of approximately 2.5 MPa, and is pressurized at 50-70°C. The mixed gas returns to the primary membrane separation device 6 through the second retentate side pipeline 18 to continue primary membrane separation. The mixed gas on the second permeate side 52 of the secondary membrane separation device 5 has a H2 concentration of 99.9%, a pressure of 50-70°C, and a pressure of 0.1 MPa, and then enters the H2 gas storage cylinder 4.

[0180] In the embodiment of the present disclosure and other possible embodiments, the mixed gas first enters the primary hydrate generation tank 1 through the air inlet 12, and the primary hydrate generation tank 1 is connected to the secondary hydrate generation tank 2 by a pipeline; the two are arranged as a whole in the upper left corner of the equipment box; a temperature and pressure integrated sensor 13 is also provided at the center position of the top end cover of the primary hydrate generation tank and the secondary hydrate generation tank, with the temperature and pressure integrated sensor 13 as the center point, the mixed gas inlet 12, the CO2 gas outlet 14, the mixed gas outlet 15, and the safety valve 11 as the vertex and arranged clockwise to form a square arranged on the end cover; the primary hydrate generation tank 1 and the secondary hydrate generation tank 2 are surrounded by a water bath 8 inside; the refrigeration unit 3 is located directly below the water bath 8, and the refrigeration unit 3 provides cooling for the 30% ethylene glycol aqueous solution in the water bath 8 when generating hydrates or heats it when decomposing hydrates; the refrigeration unit 3 is a temperature adjustment range of -10 to 30°C Refrigeration unit; the hydrate secondary generation tank 2 is connected to the gas heater 10 through a pipeline, the gas heater 10 is connected to the primary membrane separation device 6, and the retention side of the primary membrane separation device 6 is connected to the hydrate secondary generation tank through a pipeline 17; the permeate side is connected to the gas booster 9 through a pipeline, the gas booster 9 is connected to the secondary membrane separation device 5, the retention side of the secondary membrane separation device 5 is connected to the primary membrane separation device 6 through a pipeline 18, and the permeate side is connected to the H2 gas tank 4; the H2 gas tank 4 and the CO2 gas tank 16 are both located to the right of the water bath tank 8 and the refrigeration unit 3 as a whole, and the bottoms of the H2 gas tank 4 and the CO2 gas tank 16 are both located at the same horizontal position as the bottom of the refrigeration unit 3; the controller 19 is located in the center of the device box 20, and the controller 19 is connected to the temperature and pressure integrated sensor 13 on the hydrate primary generation tank 1 and the hydrate secondary generation tank 2; the controller 19 is connected to the safety valve 11, and once a gas leak occurs, the system will promptly remind you to ensure safety detection.

[0181] In the embodiment of the present disclosure and other possible embodiments, a mixed gas of 40% H2 and 60% CO2 is introduced into the gas inlet and enters the first hydrate generation tank, wherein the added concentration range is 4-10 wt% CP and 0.1-1 g Ca(OH)2 additives, the temperature is 2°C, and the pressure is 6 MPa. After the first stage separation, the H2 proportion in the mixed gas increases from 40% to 75%, and the CO2 proportion decreases from 60% to 25%. The mixed gas then continues to be introduced into the second hydrate generation tank, wherein the added concentration range is 4-10 wt% CP and 4-10 wt% TBAB additives, the temperature is 2°C, and the pressure is 4.4 MPa. After the second stage hydrate separation, the H2 proportion reaches 88%, and the CO2 proportion decreases from 25% to 12%, and the hydrate separation efficiency reaches 80%. The controller causes the refrigeration unit to provide a stable low-temperature water bath environment of 0-2°C to the hydrate generation tank, wherein the water bath coolant is set to have a content of 30% and a density of 1.041×103 kg / m 3 , an ethylene glycol aqueous solution with a specific heat capacity of 3.66 kJ / kg·k at a temperature of 25°C.

[0182] Then, the mixed gas is finally purified through the secondary membrane separation module. Since the optimal separation temperature of membrane separation is 50-70°C, a gas heater needs to be installed before membrane separation to heat the gas to about 60°C for membrane separation. After passing through the primary membrane separation device, the H2 concentration on the permeate side reaches 95% and the pressure drops to 0.1MPa; the H2 on the retention side accounts for about 70% and the pressure is 2.5MPa. At this time, the mixed gas on the retention side is just passed into the secondary hydrate generation tank to continue the secondary hydrate generation; since the pressure of the permeate side gas drops to 0.1MPa, it needs to be pressurized to 2.5MPa by a gas booster before entering the secondary membrane separation device for final separation. After passing through the secondary membrane separation device, the H2 concentration of the permeate side gas reaches 99.9%, and the H2 on the retention side accounts for about 85% to 92%, which is just passed into the primary membrane separation device for separation. The system completes the closed loop, and only the CO2 decomposed from the hydrate and the H2 gas separated by the secondary membrane separation device enter the CO2 gas storage tank 16 and the H2 gas storage tank 4 respectively.

[0183] Hydrate-based H2-CO2 separation achieves CO2 separation and capture by converting water and CO2 into CO2 hydrates under low-temperature, high-pressure conditions. Compared to traditional methods, hydrate gas separation technology offers the following advantages: 1. Raw materials are readily available, separation is rapid, reaction conditions are mild, and raw materials can be recycled; 2. Compared to cryogenic distillation, hydrate gas separation technology operates at higher reaction temperatures, typically above 0°C, effectively reducing equipment investment and energy consumption; 3. Compared to membrane separation and pressure swing adsorption, hydrate gas separation technology offers high separation efficiency, continuous operation, and minimal losses; 4. The separation process is corrosion-free and produces no pollutants; 5. It effectively captures and solidifies CO2 greenhouse gas. This technology offers significant advantages, including energy conservation, environmental friendliness, and high separation efficiency.

[0184] By organically combining the hydrate method with the membrane separation method, H2-CO2 mixed gas can be efficiently separated. After hydrate separation, the H2 concentration in the mixed gas reaches 88%, meeting the pretreatment requirements of membrane separation. Secondary membrane separation is then carried out, and the H2 concentration finally reaches 99.9%, achieving high-efficiency and low-energy separation.

[0185] The hydrate method for separating H2-CO2 mixed gases is mainly based on the differences in the phase equilibrium characteristics of gas molecules during the hydrate formation process. Figure 5The data provided in the paper show that the equilibrium pressures required for pure CO2 and pure H2 to form hydrates are 88 MPa and 86 MPa, respectively, while the equilibrium pressure for the formation of hydrates in an H2-CO2 mixture of 39.2% CO2 and 60.8% H2 is 93 MPa. This phenomenon indicates that in a gas mixture, CO2 is more likely to form CO2 hydrates with water, while H2 tends to remain in the gas phase, thus providing a thermodynamic basis for gas separation.

[0186] CO2 molecules, due to their larger kinetic diameter of approximately 0.33 nm and stronger polarity, are able to more stably occupy the large pores in the hydrate cage structure. H2 molecules, however, are smaller, approximately 0.29 nm, and are more non-polar, making them less likely to effectively stabilize the hydrate structure. Therefore, under the same conditions, CO2 is more likely to form hydrates than H2. Furthermore, the higher enthalpy of formation of CO2 hydrates indicates a stronger binding energy with the hydrate cage, further enhancing the selective capture of CO2.

[0187] Figure 5 : shows the H2-CO2 mixed gas hydrate phase equilibrium data diagram according to the embodiment of the present disclosure. Figure 5 As shown, temperature has a significant effect on the thermodynamic conditions for hydrate formation. Figure 5 The temperature range of 274K to 282K indicates that low temperatures favor the stable existence of hydrates, but appropriate pressure conditions are required to achieve efficient separation of mixed gases. Therefore, the differences in phase equilibrium, molecular size, and polarity between CO2 and H2 during hydrate formation, as well as the regulation of selectivity by temperature and pressure, provide the thermodynamic basis for the separation of H2-CO2 mixed gases using the hydrate method.

[0188] In the embodiments of the present disclosure and other possible embodiments, the technical solution proposed in the present disclosure can effectively improve the separation efficiency of the mixed gas. The H2 concentration of the mixed gas can be increased from 40% to 88% through the secondary hydrate method, meeting the gas pretreatment requirements of membrane separation. The H2 concentration is then increased from 88% to 99.9% through the secondary membrane separation method. At this time, the H2 purity reaches the concentration for industrial applications such as fuel cells and chemical raw materials. The CO2 decomposed from CO2 hydrates can also be used in oil and gas exploration, chemical raw materials and other fields, effectively realizing the separation of H2-CO2 mixed gas and the resource utilization of H2 and CO2.

[0189] In the embodiments of the present disclosure and other possible embodiments, the proposed technical solution can realize the separation of industrial tail gas (such as synthetic ammonia relaxation gas, steelmaking converter gas), biomass fermentation mixed gas, biogas fermentation products and by-product mixed gas of the electrolysis water hydrogen production process, and the mixed gas passes through the hydrate primary generation tank 1 and the hydrate secondary generation tank 2 for secondary hydrate separation and the secondary membrane separation of the primary membrane separation device 6 and the secondary membrane separation device 5, wherein the mixed gas passes through the secondary hydrate separation, CO2 in the promoter (the promoter corresponding to the primary hydrate is configured as cyclopentane Calcium hydroxide, with a corresponding accelerator configuration of cyclopentane (CP) and tetrabutylammonium bromide (TBAB), generates solid CO2 hydrate, which remains in the primary hydrate generation tank 1 and the secondary hydrate generation tank 2. However, H2, due to its smaller molecular diameter, does not form H2 hydrate. After secondary hydrate separation in the primary hydrate generation tank 1 and the secondary hydrate generation tank 2, the H2 content in the mixed gas increases from 40% to 88%. The mixed gas then passes through the primary membrane separation device 6 and the secondary membrane separation device 5 for secondary membrane separation, with the H2 content reaching 99.9%. This achieves efficient separation of the mixed gas and enrichment of H2 and CO2. The solid CO2 hydrate can be used as a gas fertilizer to supply greenhouse plant growth, or the hydrate can be decomposed to produce CO2 gas for applications such as CO2 flooding and chemical industry reaction raw materials. This solves technical problems of existing carbon capture and storage technologies, such as low CO2 capture efficiency, demanding reaction conditions, difficult mixed gas separation, and high energy consumption. The preferred technical solution provided by the present disclosure also has the advantages of a simple process, no byproducts, mild conditions, and energy conservation and environmental protection.
