Description

Technical Field

[0001] This invention relates to the field of biogeochemistry, and in particular to a method, system, equipment, and medium for quantitatively analyzing the impact of calcification of calcified organisms on carbon emissions. Background Technology

[0002] Climate warming primarily affects the marine environment by disrupting the carbonate chemical balance, leading to ocean acidification. Conversely, marine organisms, buried minerals, and sediments influence the marine chemical balance through photosynthesis-respiration and sedimentation-dissolution balance, thus impacting the climate. Specifically, calcified organisms (such as corals and shelled mollusks) affect the carbonate chemical balance in water bodies by synthesizing CaCO3, ultimately influencing atmospheric carbon content.

[0003] Therefore, calculating carbonate chemical equilibrium is fundamental to quantifying interactions between climate-biological-geological systems. In biogeochemical cycles, calculating the quantitative impact of minute changes in the studied variable on other parts of the system can be done using analytical or numerical methods. However, analytical methods are computationally cumbersome and lack scalability; numerical methods require higher precision in chemical equilibrium calculations.

[0004] For multi-species systems, the mainstream methods for calculating chemical equilibrium mainly include Gibbs energy minimization (GEM) and the law of mass action (LMA). For example, the chemical calculation software ChemSage uses Gibbs energy minimization; while many existing geochemical modeling software packages—including WATEQ, MINEQL, SOLMINEQ, and MINTEQA2—use the law of mass action. However, practical experience has shown that using software to calculate chemical equilibrium results in low accuracy. When two inputs differ by only a tiny amount, the calculated results show no significant difference, failing to meet the needs of numerical analysis for quantifying the impact.

[0005] Therefore, there is an urgent need for a new method to quantitatively analyze the impact of calcification in calcified organisms on carbon emissions. Summary of the Invention

[0076] It should be noted that the execution subject of the method for quantitatively analyzing the impact of calcification of calcified organisms on carbon emissions provided by the present invention can be any end-side device that meets the technical requirements, such as a device for quantitatively analyzing the impact of calcification of calcified organisms on carbon emissions.

[0077] In one embodiment, step S130 may include:

[0078] Based on the principle of material conservation, when the concentration of the variable under study changes by a preset range, the analytical method is used, with the product of reaction activity equal to the standard equilibrium constant as the equilibrium standard, to solve the equilibrium state of each chemical reaction in several chemical reactions, and obtain the concentration change of the variable of interest in each chemical reaction.

[0079] The concentration changes of the system variable of interest under each chemical reaction are summed to obtain the total concentration change of the system variable of interest over one cycle.

[0080] Repeat the above steps until the preset loop termination condition is reached. The preset loop termination condition includes: the total amount of concentration change of the system variable of interest no longer changes when using double-precision floating-point numbers.

[0081] Specifically, let the chemical reaction be... The expression for its equilibrium standard is:

[0082]

[0083] In the standard equilibrium expression, J represents the activity product of the chemical reaction, K represents the standard equilibrium constant of the chemical reaction, and γ a γ b γ c denoted by , where a0, b0, and c represent the activity coefficients of species a, b, and c, respectively; and a0, b0, and c0 represent the initial concentrations of species a, b, and c, respectively; and x represents the concentration change from the initial state of the chemical reaction in the target system to the equilibrium state.

[0084] In one embodiment, step S140 specifically involves:

[0085] Based on the concentration change of the variable of interest and the preset magnitude of the concentration change of the variable under study, the quantitative influence factor of the variable under study on the target system is obtained using the quantitative influence factor expression. The quantitative influence factor expression is as follows:

[0086]

[0087] In the quantitative impact factor expression, Ψ represents the quantitative impact factor of the variable under study on the target system, dsum represents the total amount of concentration change of the variable of interest in the system, and δx represents the preset magnitude of the concentration change of the variable under study.

[0088] The present invention will be described below with reference to two embodiments.

[0089] Example 1

[0090] Research objective: To determine the quantitative impact of a unit amount of CaCO3 precipitation in a given water body on atmospheric carbon emissions, specifically on CO2(g) release. In each of the following chemical formulas, (g), (aq), and (s) represent the gas phase, liquid phase, and solid phase, respectively.

[0091] Assuming the water body is open, the volume of the gas phase in the entire target system is much larger than the volume of the liquid phase. Therefore, CO2(g) entering the gas phase from the liquid phase will not affect the atmospheric composition or pressure. The entire system has a constant temperature and a pressure of 1 standard atmosphere.

[0092] For simplicity, only CO2(g) is considered in the gas phase and only H2 in the liquid phase. + OH - CO2(aq) Although CaCO3(s) exists in the solid phase, its formation is primarily kinetically controlled by biological processes. That is, while the chemical reactions or dissolution in the liquid and gas phases reach equilibrium, CaCO3(s) is far from reaching dissolution-precipitation equilibrium, so it can be disregarded. In summary, only the equilibrium states of systems containing the following four chemical reactions are considered, and the standard equilibrium constant K for each chemical equilibrium is listed. θ The activity product J is shown in Table 1. Again, to simplify calculations, the influence of solution ionic strength on ion activity is temporarily disregarded, and the activity coefficient γ for each species is taken as 1; the influence of pressure changes caused by water depth on equilibrium is also temporarily disregarded. Finally, the equilibrium standard for a single chemical reaction is simplified to the activity product J = (numerically) concentration product = standard equilibrium constant K. θ =f(T), which is a constant once the temperature T is determined.

[0093] Table 1

[0094]

[0095] Where a B = Activity coefficient × Actual concentration / Standard state concentration, dimensionless, e.g.

[0096] The system described above has two degrees of freedom; given two constraints, the system's state is determined. In this example, the input parameter is the partial pressure of atmospheric CO2. Since pH is a given factor, the initial chemical equilibrium state of the target system is set as follows:

[0097]

[0098] H represents + Ions, OH - Ions, liquid-phase CO2(aq), ion, The activity of ions, K w K0, K1, and K2 represent the standard equilibrium constants for several chemical reactions. Represents the activity coefficient of CO2(g). This represents the partial pressure of a real gas / the pressure of a standard state gas. As previously mentioned, with simplification, the activity coefficient γ of any substance in the system is 1, a B Numerically equal to the molality b of substance B B (Unit: mol / kg)

[0099] The purpose of this embodiment is to calculate the quantitative effect of a unit amount of calcium carbonate precipitation in a given water body on CO2 release. The variable to be studied is... The system variable of interest is CO2(aq), therefore a small amount of |δx| is removed from the system. have:

[0100]

[0101]

[0102] express The initial concentration, express Concentration after changing the preset amplitude value δx.

[0103] Remove |δx| Subsequently, the equilibrium of the target system is disrupted, and the chemical equilibrium is recalculated. This process enters a loop, sequentially solving for the equilibrium states of each chemical reaction to complete one iteration. That is, the chemical reactions are first calculated... The equilibrium state is: Solving using the quadratic formula, we get:

[0104]

[0105] The updated species concentrations are:

[0106]

[0107] Secondly, calculate chemical reactions The equilibrium state is: Solving using the quadratic formula, we get:

[0108]

[0109] The updated species concentrations are:

[0110]

[0111] Next, calculate chemical reactions. The equilibrium state is: Solving using the quadratic formula, we get:

[0112]

[0113] The updated species concentrations are:

[0114]

[0115] The variable `dsum` is used to accumulate the concentration change of the system variable of interest, CO2(aq), in all chemical reactions during this cycle. In this example, `dsum` represents the cumulative change of CO2(aq) in the liquid phase, which in practice is the amount of CO2 that moves from the liquid phase to the gas phase per unit mass of water. This represents the initial concentration of CO2(aq). dsum represents the final concentration of CO2(aq), dsum represents the total amount of CO2(aq) concentration change accumulated in all previous cycles, and dsum′ represents the total amount of CO2(aq) concentration change updated after one cycle.

[0116] Finally, the dissolution process is calculated. The equilibrium state is such that the gas phase is much larger than the liquid phase. The value is determined by the atmosphere The decision will be made to return to the initial state. Calculating the chemical equilibrium of all chemical reactions and summing the concentration changes of the system variable of interest in all chemical reactions constitutes one iteration. This iteration continues until a preset termination condition is met. The preset termination condition is that, in double-precision floating-point numbers, dsum no longer changes; that is, the total concentration change that no longer changes is taken as the final dsum of the system variable of interest. Then, the quantitative influence factor Ψ of the small changes in the variable under study on the system variable of interest is calculated.

[0117] In this embodiment, the quantitative impact factor represents how much CO2 emission will be caused by a unit of CaCO3 precipitation. This value can be used to calculate carbon emissions. For example, Shenzhen produces 2,000 tons of shellfish annually through shellfish farming, which is approximately 2,000 tons of CaCO3, = 20,000,000 mol. The quantitative impact factor is calculated to be 0.7 in the water environment of Shenzhen, so the CO2 release is approximately 20,000,000 × 0.7 × 44 g / mol = 616 tons.

[0118] Example 2

[0119] Research objective: To quantitatively calculate the effect of CaCO3 precipitation in a closed water body on the resulting CO2(g) release.

[0120] The water body is a closed system, and the volume of the gas phase in the entire target system is much smaller than the volume of the liquid phase. Therefore, CO2(g) entering the gas phase from the liquid phase will not affect the liquid phase components. The entire system has a constant temperature and a pressure of 1 standard atmosphere.

[0121] Unlike Example 1, since the gas phase no longer affects the liquid phase components, only the following three chemical reactions need to be considered during the re-establishment of equilibrium after the disturbance. Apart from this, the other steps are the same as in Example 1.

[0122]

[0123] This invention provides a method, system, equipment, and medium for quantitatively analyzing the impact of calcification of calcified organisms on carbon emissions. It can rapidly calculate the final chemical equilibrium state of a target system after micro-perturbation, with high calculation accuracy. It can obtain the changes between the initial and final states of the system that traditional chemical equilibrium calculation methods cannot show, thus improving interpretability. Furthermore, after obtaining the quantitative impact factor of the change of the variable under study on the target system, the mass of the variable of interest can be obtained by combining the molar mass of the variable under study under actual conditions, thereby accurately assessing the impact of the variable under study on the variable of interest in the target system.

Based on computational chemical equilibrium, it employs numerical analysis to quantitatively simulate the impact of changes in environmental factors on the entire carbonate system. It is primarily applied to quantitatively analyze the impact of calcification by organisms such as corals and clams on carbon emissions in different environments. This invention has high scalability; new chemical reactions can be flexibly added depending on the research system. This invention has application value in marine and other aquatic ecosystem fields, supporting the construction of carbon flux modules in marine and other aquatic ecosystem models, and overcoming the shortcomings of low algorithm intuitiveness, weak theoretical basis, and poor scalability in this application field.
