Description

Technical Field

[0002] As the carbon trading market gradually becomes standardized and factories' carbon inventory and carbon verification become more precise, accurate measurement of carbon dioxide emissions from industrial production is crucial.

[0003] Volatile organic compounds (VOCs) are very common by-products in industrial production processes. At present, waste gas treatment devices are mainly used to remove volatile organic compounds in waste gas. In the waste gas treatment device, the volatile organic compounds in the waste gas will undergo an oxidation reaction at high temperature, and the hydrocarbons therein will be converted into carbon dioxide and water and discharged directly into the atmosphere. Therefore, the carbon dioxide emissions generated by volatile organic compounds in the waste gas must be included in the total carbon emissions of the factory. However, because the carbon dioxide emissions generated by volatile organic compounds are difficult to accurately estimate, the carbon dioxide emissions generated by volatile organic compounds are usually ignored in carbon emission calculations, making it difficult to accurately calculate the carbon dioxide emissions from industrial production.

Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0041] To facilitate understanding, an exhaust gas treatment system applicable to the embodiment of the present disclosure is first exemplarily described below.

[0042] Figure 1 The structure diagram of the exhaust gas treatment system provided by the embodiment of the present disclosure is shown. Figure 1 The exhaust gas treatment system 100 may include: an exhaust gas treatment device 110 and a control device 120. The control device 110 may be used to perform the carbon emission measurement method described below on the exhaust gas discharged from the exhaust gas treatment device 120.

[0043] See also Figure 1 The waste gas treatment device 110 can be used to perform treatments such as incineration on gaseous pollutants such as organic polymer raw materials to convert them into carbon dioxide and water for discharge. When the waste gas treatment device performs treatments such as incineration on gaseous pollutants, if they are completely burned, they are converted into carbon dioxide, and if they are not completely burned, volatile organic compounds are generated. Incomplete combustion in the waste gas treatment device 110 occurs from time to time, so the waste gas generated by the waste gas treatment device 110 contains carbon dioxide and volatile organic compounds.

[0044] In specific applications, the exhaust gas treatment device 110 may be, but is not limited to, an exhaust gas catalytic combustion device (CO), a regenerative thermal incinerator (RTO), a direct-fired incinerator (TO), a zeolite wheel adsorption (VOC), etc. A monitoring device may be provided in the exhaust gas treatment device, such as a volatile organic compound monitoring device, which may be used to monitor the exhaust gas discharged from the exhaust gas treatment device to obtain exhaust gas emission data.

[0045] The control device 120 can be used to control the operation of the exhaust gas treatment device. Specifically, the control device can be used for, but not limited to: obtaining user instructions through, for example, a human-machine interface, an input device such as a key, or based on a pre-written automatic control program to configure, power on, start, shut down, reset parameters, and other operations on the exhaust gas treatment device. In addition, the control device can also be used to communicate with a third-party platform such as the pollution source information management platform 200 to synchronize the emission data of the exhaust gas discharged by the exhaust gas treatment device, the total carbon dioxide emission equivalent of the exhaust gas, and other information to the third-party platform in real time.

[0046] In specific applications, the control device 120 can be implemented as, but not limited to, a computer, a server, a client, a portable electronic device, etc. The control device 120 and the exhaust gas treatment device 110 can be connected by wire, such as a cable, or can be connected by wireless means, such as Bluetooth, Ethernet, etc. In other embodiments, the control device can be embedded in the exhaust gas treatment device in the form of a microcontroller, etc.

[0047] The waste gas treatment system of the embodiment of the present disclosure can be applied to various fields. For example, the waste gas treatment system of the embodiment of the present disclosure can be applied to scenes such as industrial production that are prone to generate gaseous pollutants.

[0048] It should be noted that the previous Figure 1 The structure of the exhaust gas treatment system shown is for illustration only. Those skilled in the art should understand that the exhaust gas treatment system architecture in a specific application can be flexibly adjusted as needed.

[0049] The carbon emission calculation method provided in the embodiment of the present disclosure is described in detail below.

[0050] Figure 2 1 shows a flow chart of the carbon emission calculation method provided by the embodiment of the present disclosure. The carbon emission calculation method provided by the embodiment of the present disclosure can be executed by the control device 120 in the exhaust gas treatment system 100. Figure 2 , the method of the embodiment of the present disclosure may include:

[0051] Step 201, obtaining emission data of waste gas discharged from the waste gas treatment device of the carbon verification object;

[0052] Step 202, determining the emission amount of volatile organic compounds in the exhaust gas according to the emission data;

[0053] Step 203, determining the carbon dioxide equivalent corresponding to the volatile organic compounds according to the emission amount of the volatile organic compounds in the exhaust gas;

[0054] Step 204, determining the amount of carbon dioxide emissions in the exhaust gas based on the amount of volatile organic compounds emissions in the exhaust gas;

[0055] Step 205 , determining the total carbon dioxide emission equivalent of the exhaust gas based on the carbon dioxide equivalent corresponding to the volatile organic compounds and the carbon dioxide emission in the exhaust gas.

[0056] In the embodiments of the present disclosure, the carbon verification object refers to an object whose waste gas emissions need to be carbon verified. For example, the carbon verification object may be, but is not limited to, a factory, manufacturer, or other similar object that emits waste gas.

[0057] Through the embodiments of the present disclosure, not only can the carbon dioxide emissions in the waste gas emitted by the carbon verification object be accurately measured, but also the carbon dioxide generated by volatile organic compounds in the waste gas emitted by the carbon verification object can be accurately measured, thereby achieving accurate calculation of the total emission equivalent of carbon dioxide in the waste gas emitted by the carbon verification object.

[0058] In step 201, there are many specific implementation methods for obtaining the exhaust emission data.

[0059] In some examples, the emission data of the carbon verification object can be obtained from the pollution source information management platform of the area to which the carbon verification object belongs. In specific applications, the exhaust gas treatment system of the carbon verification object will synchronize its detected exhaust gas emission data to the pollution source information management platform in real time. Therefore, the control device can obtain the emission data of the exhaust gas emitted by the carbon verification object from the pollution source information management platform.

[0060] In some examples, a volatile organic compound monitoring device built into or external to the exhaust gas treatment device can be used to detect the exhaust gas to obtain the exhaust gas emission data. The volatile organic compound monitoring device may include a gaseous pollutant monitoring unit and a flue gas parameter detection unit. In specific applications, the volatile organic compound monitoring device can monitor the emission data of the exhaust gas discharged by the exhaust gas treatment device in real time and provide it to the control device so that the control device can obtain the exhaust gas emission data in real time.

[0061] The exhaust gas emission data may include, but are not limited to, the density of volatile organic compounds, smoke flow, and smoke flow passage time. In addition, the exhaust gas emission data may also include: the exhaust port gas detection time, etc. The duration between the start time and the end time of the exhaust port gas detection time may be used as the smoke flow passage time. For example, if the volatile organic compounds in the exhaust gas include methane and non-methane total hydrocarbons, the exhaust gas emission data may include: methane density, non-methane total hydrocarbon density, smoke flow, and smoke flow passage time.

[0062] In the embodiments of the present disclosure, the volatile organic compounds in the exhaust gas vary depending on the scene, the gas pollutants, and the organic polymer raw materials used by the carbon verification object. For example, the volatile organic compounds in the exhaust gas may include but are not limited to methane, non-methane total hydrocarbons, or other similar gases.

[0063] There are many ways to determine the emission of volatile organic compounds in step 202. In some examples, the emission of each volatile organic compound can be calculated by the following formula (1).

[0064] M V =ρ V ×V×t÷10 6 (1)

[0065] Among them, M V is the emission of volatile organic compounds in the exhaust gas discharged by the exhaust gas treatment device (unit: kg), ρ V is the density of volatile organic compounds (unit: milligrams per cubic meter mg / m 3 ), V is the flue gas flow rate (unit: cubic meters per hour m 3 / h), t is the passage time of flue gas flow.

[0066] For example, if the data of the pollution source information management platform is collected every hour by default, and the carbon emission calculation of the embodiment of the present disclosure is performed on the exhaust gas discharged by the exhaust treatment device every hour by default, the flue gas flow rate passing time t is recorded as one hour (1h).

[0067] For example, if the VOCs in the exhaust gas include methane and non-methane hydrocarbons, the emissions can be calculated separately.

[0068] The methane emission can be calculated based on the methane density, the flue gas flow rate and the flue gas flow time. Specifically, the non-methane total hydrocarbon emission can be calculated by the following formula (2).

[0069] M C =ρ C ×V×t÷10 6 (2)

[0070] Among them, M C is the methane emission in the exhaust gas discharged from the exhaust gas treatment device (unit: kg); ρ c is the methane density (unit: mg / m 3 ), V is the flue gas flow rate (unit: m 3 / h), t is the flue gas flow time.

[0071] The non-methane total hydrocarbon emission can be calculated based on the non-methane total hydrocarbon density, the flue gas flow rate and the time for the flue gas flow rate to pass. Specifically, the non-methane total hydrocarbon emission can be calculated using the following formula (3).

[0072] M NC =ρ NC ×V×t÷10 6 (3)

[0073] Among them, M NC is the total non-methane hydrocarbon emissions in the exhaust gas discharged from the exhaust gas treatment device, ρ NC is the total non-methane hydrocarbon gas density (unit: mg / m 3 ), V is the flue gas flow rate (unit: m 3 / h), t is the flue gas flow time.

[0074] In step 203, the carbon dioxide equivalent of each volatile organic compound can be determined in different ways as needed. In some examples, the GWP method can be used for determination, that is, the carbon dioxide equivalent equivalent to the greenhouse effect caused by the volatile organic compound can be calculated based on the GWP value of the volatile organic compound, the GWP value of carbon dioxide, and the emission of the volatile organic compound. In some examples, the chemical element analysis method (i.e., the element mass conservation method) can be used, that is, the carbon dioxide equivalent equivalent of the volatile organic compound can be calculated based on the carbon content in the volatile organic compound and the relative molecular mass of carbon dioxide.

[0075] For example, if the volatile organic compounds in the exhaust gas include methane and non-methane total hydrocarbons, their corresponding carbon dioxide equivalents can be calculated separately, that is, the methane emissions and non-methane total hydrocarbon emissions can be converted into carbon dioxide equivalents respectively.

[0076] In some examples, methane emissions can be converted into carbon dioxide equivalents by using the GWP value. Specifically, methane emissions can be converted into carbon dioxide equivalents by using the following formula (4), where the carbon dioxide equivalents are the carbon dioxide equivalents corresponding to the methane emissions.

[0077]

[0078] in, is the carbon dioxide equivalent corresponding to methane emissions (in kgCO 2 e), M C It is the methane emission in the exhaust gas discharged from the exhaust gas treatment device (in kg). GWP C represents the GWP value of methane, Indicates the GWP value of carbon dioxide. According to the latest assessment results of the IPCC Sixth Assessment Report, GWP C The value of is 29.8, The value of is 1, that is, the greenhouse effect caused by emitting 1 unit of methane is equivalent to the greenhouse effect caused by emitting 29.8 units of carbon dioxide.

[0079] In some examples, the carbon dioxide equivalent corresponding to the non-methane total hydrocarbon emissions can be determined by chemical element analysis. Specifically, the non-methane total hydrocarbon emissions can be converted into carbon dioxide equivalents by the following formula (5), and the carbon dioxide equivalent is the carbon dioxide equivalent corresponding to the non-methane total hydrocarbon emissions.

[0080]

[0081] in, is the carbon dioxide equivalent corresponding to the total non-methane hydrocarbon gas emissions (in kgCO 2 e); M NC is the total non-methane hydrocarbon emission in the exhaust gas discharged from the exhaust gas treatment device (kg), "12.01" is the relative atomic mass of carbon element C, and "44.01" is carbon dioxide CO 2 The relative molecular mass.

[0082] Of course, in specific applications, other methods may be used to convert the emission of volatile organic compounds into equivalent carbon dioxide equivalents, and the embodiments of the present disclosure do not limit this.

[0083] In step 204, the emission of carbon dioxide in the exhaust gas can be calculated based on the treatment efficiency of the exhaust gas treatment device and the sum of the emission of all volatile organic compounds in the exhaust gas. The treatment efficiency of the exhaust gas treatment device can be pre-configured in the memory of the control device as a parameter of the exhaust gas treatment device, and the control device can directly read it from the memory when needed.

[0084] In some examples, if the volatile organic compounds in the exhaust gas include methane and non-methane total hydrocarbons, the carbon dioxide emissions in the exhaust gas discharged from the exhaust gas treatment device can be calculated by the following formula (6).

[0085]

[0086] in, M is the carbon dioxide emission in the exhaust gas discharged by the exhaust gas treatment device (kg); C is the methane emission in the exhaust gas discharged from the exhaust gas treatment device (kg), M NC is the total non-methane hydrocarbon emissions in the exhaust gas discharged by the exhaust gas treatment device (kg), a is the proportion of carbon dioxide emissions in the exhaust gas discharged by the exhaust gas treatment device (%), that is, a represents the treatment efficiency of the exhaust gas treatment device. 1-a is the proportion of methane emissions and total non-methane hydrocarbon emissions in the exhaust gas discharged by the exhaust gas treatment device (%).

[0087] In practical applications, according to HJ 1093-2020 "Technical Specifications for Industrial Organic Waste Gas Treatment Engineering by Regenerative Combustion", the purification efficiency of a two-chamber regenerative combustion device should not be less than 95%, and the purification efficiency of a multi-chamber or rotary regenerative combustion device should not be less than 98%. Therefore, the value range of a is above 95%, and the specific value can be set according to the treatment efficiency of the waste gas treatment device installed in the factory.

[0088] In step 205 , the total carbon dioxide emission equivalent may be the sum of the carbon dioxide equivalent corresponding to each volatile organic compound and the carbon dioxide emission in the exhaust gas.

[0089] In some examples, if the volatile organic compounds in the exhaust gas include methane and non-methane hydrocarbons, the total carbon dioxide emission equivalent can be calculated by the following formula (7):

[0090]

[0091] Where ∑T is the total carbon dioxide emission equivalent (kgCO 2 e), The carbon dioxide equivalent (kgCO2) corresponding to the total non-methane hydrocarbon emissions in the exhaust gas discharged by the exhaust gas treatment device after conversion 2 e), The carbon dioxide equivalent (kgCO2) corresponding to the methane emission in the exhaust gas discharged by the exhaust gas treatment device after conversion 2 e), The amount of carbon dioxide emitted from the exhaust gas treatment device (unit: kg, also written as kgCO 2 e).

[0092] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to specific application examples.

[0093] Figure 3 The figure shows a schematic diagram of the carbon dioxide measurement process in the exhaust gas discharged from the regenerative thermal oxidizer (RTO) installed in Factory A.

[0094] The gaseous pollutants produced by the organic polymer raw materials used by Factory A include volatile organic compounds, which are all sent to the waste gas treatment system for treatment. The volatile organic compounds in the gaseous pollutants are completely burned in the waste gas treatment device and converted into carbon dioxide in the waste gas, and the incompletely burned volatile organic compounds are converted into methane, non-methane total hydrocarbons and other volatile organic compounds in the waste gas. The method of the embodiment of the present disclosure can be used to measure the carbon dioxide emissions converted from the complete combustion of volatile organic compounds, and the carbon dioxide equivalent corresponding to the methane, non-methane total hydrocarbons and other volatile organic compounds produced by incomplete combustion.

[0095] First, the emission data of the waste gas discharged by the waste gas treatment device is obtained through gas flow monitoring, and the control device uploads the emission data to the pollution source information management platform. The emission data includes: methane density, non-methane total hydrocarbon density, flue gas flow, flue gas flow passing time, and the monitoring time is recorded.

[0096] Then, the exhaust gas emission data, namely, methane density, non-methane total hydrocarbon density, flue gas flow rate, and detection time information (i.e., flue gas flow rate through time, from 0:00 to 23:00 on January 31) were obtained from the pollution source information management platform of the province where Factory A is located. Taking the detection situation of Branch Factory A from 0:00 to 23:00 on January 31 as an example, the emission data are shown in Table 1 below.

[0097]

[0098] Table 1

[0099] Third, based on the exhaust gas emission data, the methane emissions and non-methane total hydrocarbon emissions in the exhaust gas emitted by the exhaust gas treatment device of Factory A from 0:00 to 23:00 on January 31 were calculated using the above formulas (2) and (3). The calculation results of methane emissions and non-methane total hydrocarbon emissions are shown in Table 2 below.

[0100]

[0101] Table 2

[0102] It can be seen from Table 2 that from 0:00 to 23:00 on January 31, the total non-methane hydrocarbon emissions of Factory A totaled 3.66 kg and the total methane emissions totaled 1.20 kg.

[0103] Fourth, calculate the carbon dioxide emission equivalents corresponding to the non-methane hydrocarbons and the carbon dioxide emission equivalents corresponding to methane in the exhaust gas emitted by Factory A from 0:00 to 23:00 on January 31. Based on the data in Table 2, the carbon dioxide emission equivalents corresponding to methane can be calculated by the above formula (4), and the carbon dioxide emission equivalents corresponding to the non-methane hydrocarbons can be calculated by the above formula (5). Through calculation, it is found that the carbon dioxide emission equivalents corresponding to methane in the exhaust gas emitted by Factory A from 0:00 to 23:00 on January 31 are 35.69kgCO 2 e, the carbon dioxide emission equivalent corresponding to non-methane total hydrocarbons is 13.42kgCO 2 e.

[0104] Fifth, calculate the carbon dioxide emissions from the exhaust gas emitted by Factory A from 0:00 to 23:00 on January 31. The treatment efficiency of the exhaust gas treatment device of Factory A is clearly stated in the system technical specification of the device: a = 95%. According to the above formula (6), the carbon dioxide emissions from the exhaust gas emitted by Factory A from 0:00 to 23:00 on January 31 are 92.36 kg, which can also be written as 92.36 kgCO 2 e.

[0105] Finally, the total carbon dioxide emission equivalent in the exhaust gas emitted by Factory A from 0:00 to 23:00 on January 31 can be calculated by the above formula (7) as 141.48 kgCO 2 e, that is, from 0:00 to 23:00 on January 31, the total carbon dioxide emission equivalent generated by Factory A due to the gaseous pollutants generated by the treatment of organic polymer raw materials was 141.48 kgCO 2 e.

[0106] It can be seen that the total carbon dioxide emission equivalents generated by the treatment of gaseous pollutants by Factory A can be accurately calculated through the embodiments of the present disclosure. The carbon dioxide emission equivalents corresponding to methane and the carbon dioxide emission equivalents corresponding to non-methane total hydrocarbons in the total carbon dioxide emission equivalents were previously ignored by Factory A, accounting for about 2% of the annual carbon dioxide emission equivalents of Factory A. The embodiments of the present disclosure can accurately estimate the carbon dioxide emission equivalents corresponding to volatile organic compounds, include them in the total carbon dioxide emission equivalents, and achieve accurate measurement of the carbon dioxide emission equivalents of Factory A.
