Referring to FIG. 1, the system of the present invention thermally decomposes sulfur hexafluoride (SF ₆ ) into a sulfur (S) source and a fluorine (F) source through plasma, and then reacts with quicklime (CaO) present in a cement kiln, calcium sulfate (CaSO ₄₎ and calcium fluoride (CaF ₂₎ to the immobilized, wherein immobilized calcium sulfate (CaSO ₄₎ and calcium fluoride (CaF ₂₎ to the fine-powdered screen to create a cement cement kiln system 10, a cement kiln Greenhouse gas management system 20 that calculates the amount of greenhouse gas removal by comparing the amount of sulfur hexafluoride (SF ₆ ) injected into the system 10 and the amount of sulfur hexafluoride (SF ₆ ) emitted from the cement kiln system 10, and the greenhouse A carbon credit management system 30 that acquires carbon credits proportional to the amount of gas removed and adjusts the remaining amount of carbon credits of the cement kiln system 10 based on the carbon credits, and an e-commerce system 40 that supports electronic commerce of carbon credits. ) Can be included.

The carbon credit management system 30 receives and manages the carbon credits of the cement kiln system 10 every year, and the carbon credits are deducted according to the emission of various greenhouse gases generated by the cement kiln system 10. In other words, carbon emission is calculated based on the type of greenhouse gas, emission, and global warming index (GWP), and the remaining amount of carbon credits is calculated by subtracting it from the allocated carbon credits.

Hereinafter, Table 1 is a table showing the global warming index (GWP) for each type of greenhouse gas.

Greenhouse gas (chemical formula) GWP (per ton) Carbon dioxide (CO ₂ ) One Methane (CH4) 21 Nitrous oxide (N2O) 310 Hydrogen fluorocarbons (HFCs) 1,300 Perfluorocarbons (PFCs) 7,000 Sulfur hexafluoride (SF ₆ ) 23,900

Hereinafter, an operation method of the present invention will be described with reference to FIGS. 3 to 6.

3 is an operation flowchart illustrating a method of calculating carbon credits according to an embodiment of the present invention, FIG. 4 is a flowchart of an entire process of cement production, and FIGS. 5 and 6 are flowcharts of a cement firing process.

First, in the operation and management plan establishment step of step S1, the cement kiln system operation plan, daily/monthly/yearly SF ₆ purchase amount and injection amount, measurement device information, and measurement analysis management information are input into the data input module. Cement kiln refers to a kiln that fires crushed cement raw materials by mixing in an appropriate ratio. According to Article 11 of the Guidelines for Reporting and Certification of Emissions under the Greenhouse Gas Emissions Trading Scheme, companies subject to allocation are monitoring plans including an overview of emission activities, emission facilities subject to reporting, greenhouse gases subject to reporting, emission calculation methodology, and management standards for each parameter. For this purpose, the cement kiln system operation plan, daily/monthly/yearly SF ₆ purchase amount and injection amount, measurement equipment information, and measurement analysis management information are entered into the data input module.

The greenhouse gas to be reported in the present invention is a fluorine-based greenhouse gas, specifically, HFCs, PFCs, SF ₆ and the like. Fluorine-based greenhouse gases are sometimes used during product production processes in the chemical industry or the electricity industry, but are consumed for various purposes, such as fillings of the produced facilities. In particular, SF ₆ is mainly needed (consumed) in the heavy electric machinery industry and the electric and electronic industries, and SF ₆ is expected to continue to be in demand as there is no immediate replacement item. As SF ₆ prices are on the decline, the business that reuses SF ₆ gas recovered and refined and disposed of is expected to weaken competitiveness and increase the amount of SF ₆ used.

Then, in the operation step of the SF ₆ treatment/fixation process of step S2, the plasma-generated HF gas and SF ₆ previously decomposed in the cement process kiln are chemically reacted with quicklime (CaO) as a reactant, which is a useful material in the cement process. Immobilized with CaF ₂ (mineralizer) and CaSO ₄ (retardant). At this time, the amount of sulfur hexafluoride injected from the measuring device in real time, the temperature and the discharge amount; The temperature of the cement kiln system; And temperature measurements of the reactants are received and input to the management module.

In one embodiment of the present invention, to improve the pre-heater system, a rotary kiln, or the cooler to inject SF ₆ and a source of hydrogen in the process of progress of cement sintering step, and decomposing the heat SF ₆ occurring in the cement sintering process , Decomposed S and F could be used as materials for clinker synthesis, and a large amount of SF ₆ was used as a raw material.

As a heat source for converting SF ₆ to HF by pyrolysis in advance, a heat source of 1,000℃ or higher generated during the cement firing process is used. In addition, thermal energy may be additionally supplied through the plasma generator.

When SF ₆ is introduced as a raw material, it is pyrolyzed into a sulfur (S) source and a fluorine (F) source by plasma, which reacts with CaO present in the cement kiln and is immobilized with calcium sulfate (CaSO ₄ ) and calcium fluoride (CaF ₂ ). (See Figs. 5 and 6).

Sulfur (S) through SF ₆ pyrolysis combines with oxygen contained in excess air to form SO ₄ (sulfone group), and SO ₄ reacts with CaO (quicklime) to produce CaSO ₄ , where active material and chemical admixture It becomes cement when it is made into fine powder by mixing etc.

S + 2O ₂ → SO ₄

2CaO + 2SO ₄ → 2CaSO ₄ + O ₂

In the case of fluorine (F) through SF ₆ pyrolysis, it can corrode other substances, so it is necessary to supply a hydrogen source (H ₂ O, H _2, etc.), and the hydrogen atoms contained in these hydrogen sources are F and It reacts to make HF, which is relatively easily converted, and reacts with CaO (quicklime) to induce the next chemical reaction.

H ₂ + F ₂ → 2HF

CaO + 2HF → CaF ₂ + H ₂ O + heat

CaSO ₄ is also called gypsum, and can be used as an admixture to promote the hydration of cement. CaF ₂ plays a role in lowering the firing temperature in the manufacturing stage of cement clinker. When the limestone is decarboxylated by CaF ₂ generated by immobilization, the firing temperature can be reduced by about 100 to 200 ℃, so there is an energy saving effect. Therefore, CaF ₂ generated by immobilization is essential in the clinker firing process, which accounts for the most energy consumption in the cement production process.

In the cement kiln, a material capable of immobilizing S and F decomposed from SF ₆ , and quicklime (CaO) is less than about 2% after firing. It is desirable to exist

It is preferable that the temperature of quicklime (CaO) as a raw material of the reactant is adjusted to 700 to 2,000°C, and the temperature of sulfur hexafluoride to 1,000 to 5,000°C. If it is within the above range, permanent immobilization with 100% CaF ₂ and CaSO ₄ is possible, and cement can be produced without a separate treatment process.

And in the data aggregation (management) step for calculating the amount of discharge in step S3, the management module includes: the amount of sulfur hexafluoride injected, the temperature, and the amount of discharge; The temperature of the cement kiln; And to measure the temperature of the reactant in real time.

And in the step of calculating the amount of SF ₆ emission according to the decomposition/fixation of SF _{6 in} step S4, the amount of SF ₆ emission is calculated through the following GHG emission calculation method.

The present inventors reviewed the possibility of applying the method of calculating the decomposition rate (reduction factor) proposed in a similar methodology to which the GHG reduction technology was applied as a method of calculating GHG emissions. As a result, it was confirmed that the untreated process gas emission can be regarded as the undecomposed (unfixed) SF ₆ emission.

In one embodiment of the present invention, the GHG emission calculation method is expressed by the following equation.

E _i = Q _i x (1-DR _i )

Injection amount (ton) and, DR _i is the decomposition rate of the implanted SF ₆ (i) (a fixed ratio) in the greenhouse gas emissions (tGHG) and, Q _i is SF ₆ (i) of the formula E _i is SF ₆ (i) Is a prime number between 0 and 1, and is calculated by DR _i = (Q _i -R _i )/Q _i , R _i is the discharge (ton) of SF ₆ (i) discharged through the outlet.

The parameter Q _i of the activity data of the above GHG emission calculation formula is a measure of the amount of SF ₆ consumed in the process. The emission factor (parameter DR _i of the rate of fixation (distribution) is the rate at which the spent SF ₆ is not released to the atmosphere but is fixed (decomposed). The consumption of SF ₆ (Q _i ) is measured immediately before entering the kiln. The amount of SF ₆ (R _i ) discharged after using raw materials in the cement production process is measured immediately after SF ₆ is discharged from the kiln outlet.

The above GHG emission calculation formula applies the concept of 1-decomposition rate when it is input to a process (emission facility) and consumed, or when decomposition (destruction) is processed through a reduction system, and in the case of the process of the present invention, SF ₆ is used as an auxiliary material. It is a concept of primarily decomposing SF ₆ using a high-temperature heat source (plasma) and immobilizing it as an auxiliary material (CaSO ₄ , CaF ₂ ), similar to the concept of applying a reduction system of similar methodology. Therefore, the method of calculating the decomposition rate (decomposition coefficient) applied in the case of decomposition (decomposition) treatment through the reduction system was applied mutatis mutandis. The concept of (inflow-discharge)/inflow was applied to the calculation of the failure rate (or decomposition factor).

The above GHG emissions calculation formula is a method of calculating GHG emissions when SF ₆ input for cement production is not immobilized as a final product (i.e., undegraded/unfixed) and can be discharged to the atmosphere. ) And the amount of SF ₆ emitted can be measured (analyzed) and applied.

In the step S5 of calculating the amount of GHG removal, the amount of GHG removal is calculated by comparing the amount of sulfur hexafluoride (SF ₆ ) calculated through step S4 with the amount of sulfur hexafluoride (SF ₆ ) injected. That is, in the process of treating sulfur hexafluoride while manufacturing cement sub-materials in the cement sintering facility, it is to calculate how much greenhouse gas is removed.

And in the conversion step to the carbon emission source of step S6, the amount of greenhouse gas removal calculated through step S5 is reported to the carbon credit management system 30, and the carbon credit management system 30 is the carbon of sulfur hexafluoride (SF ₆ ). Based on the emission factor, the amount of greenhouse gas removed should be converted into carbon credits.

Carbon credits (Certificated Emissions Reduction: CER) can be converted according to the following equation.

CER = (R _i -Q _i ) λ

In the above formula, λ is the carbon emission factor of sulfur hexafluoride (SF ₆ ). In the case of sulfur hexafluoride (SF ₆ ), the ability of SF6 to destroy ozone is 23900 times when carbon dioxide is 1 as a standard. Accordingly, in the present invention, the carbon emission factor λ of sulfur hexafluoride (SF ₆ ) may be set to 23900.

Then, the carbon credit management system 30 is a transaction channel that enables the transfer of carbon credits of a specific user account from another person or the transfer of the carbon credits of another person, and a settlement that enables payment of the transaction costs in various ways. By creating and operating channels in various forms, it will smoothly support e-commerce of carbon credits. The carbon credits of the present invention may be traded in at least one of selling-buying, trust processing, auction, and donation, but of course, the form of e-commerce may be changed or modified if necessary.

In one embodiment of the present invention, preferably in real time, the amount of sulfur hexafluoride injected, the temperature and the amount of discharge; The temperature of the cement kiln; The temperature of the reactants; Greenhouse gas emissions; And it may further include a display module for visualizing the amount of carbon credits obtained and the remaining amount.
