Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1, a flow of an embodiment of a fossil fuel fired emissions accounting method according to an embodiment of the present application is shown. The fossil fuel combustion emission accounting method comprises the following steps:
and step 101, calculating the discharge amount of fossil fuel in the target area by adopting a reference method to serve as the reference discharge amount.
In this embodiment, the reference method is obtained by comprehensively calculating parameters such as apparent consumption of various fossil fuels, unit calorific value and carbon content of various fuel varieties, and average carbon oxidation rate of main equipment for burning various fuels, and deducting the carbon fixation amount for non-energy use of fossil fuels. As an example, the calculation formula is:
carbon dioxide emission (fuel consumption (heat unit) × carbon content per calorie fuel — solid carbon content) × carbon oxidation rate in fuel combustion process × 44/12
For example, the reference method comprises the steps of:
step one, acquiring the fuel consumption of a target area. Specifically, it can be calculated by the following formula:
the apparent consumption of primary energy is primary energy production, outsourced/regional income, local city/regional output, in-environment ship and airplane refuelling amount outside environment, out-environment ship and airplane refuelling amount inside environment, initial stock, end stock, import and export
Apparent consumption of secondary energy (external city/regional income-local city/regional income + overseas oil supply of ship and airplane outside environment-overseas oil supply of ship and airplane in environment + initial stock-end stock + import quantity-export quantity
And step two, converting the fuel consumption into a uniform heat unit.
Specifically, it can be calculated by the following formula:
fuel consumption (heat unit) ═ fuel consumption x conversion factor (fuel unit heat value)
And step three, determining the total carbon content of the fossil fuel based on the fuel consumption of heat units.
Specifically, it can be calculated by the following formula:
the carbon content of the fuel ∑ Σ [ fuel consumption (heat unit) × carbon content per fuel (carbon content per calorific value of fuel) ], i.e., the product of the consumption of each type of fuel and the carbon content per fuel is summed, Σ in the present application representing the summation of each type.
And step four, determining the carbon fixation amount of the fossil fuel.
The carbon fixation amount, namely the amount of carbon fixed in the product for a long time, can be calculated by the following formula:
carbon fixation yield ═ Σ (yield of carbon fixation product x carbon content per unit product x carbon fixation rate)
Or
Solid carbon amount ═ Σ (fuel amount for non-energy use x carbon content per unit fuel x solid carbon rate)
And step five, determining the discharge amount of the fossil fuel in the target area based on the total carbon content of the fossil fuel and the fixed carbon content of the fossil fuel.
Specifically, it can be calculated by the following formula:
the actual emission of carbon dioxide is the net emission of carbon dioxide, which is the total carbon content of the fuel-the amount of solid carbon, x the rate of carbon oxidation during combustion of the fuel x 44/12.
Wherein: the carbon fixation rate is the fixed carbon ratio of various fossil fuels in the process of being used as non-energy, and the carbon is not released, so the carbon needs to be deducted in the calculation of emission; the carbon oxidation rate represents the oxidation rate of various fossil fuels in the combustion process, namely the rate of various fossil fuels for combustion which are finally oxidized and discharged into the atmosphere, so as to calculate the real carbon dioxide emission in the combustion process of the fossil fuels.
And 102, calculating the discharge amount of fossil fuel in the target area by adopting a source classification method to serve as the standard discharge amount.
In this embodiment, the source classification method is to collect activity level data of source classification fuel varieties from bottom to top, combine parameters or emission factors such as unit calorific value and carbon content of the fuel, and carbon oxidation rate, and sum up layer by layer to obtain total emission. The source types are all fields or industries and sub-equipment (the equipment in different fields has different meanings, such as sub-equipment in the industrial field, sub-vehicle type in the traffic field and sub-building energy utilization path in the building field). The basic formula is:
E＝AD×EF
wherein E represents the amount of greenhouse gas emitted;
AD represents activity level, is the amount of fuel consumed in accounting and reporting years, measured in physical quantities;
EF denotes an emission factor, which is an emission factor for carbon dioxide, methane and nitrous oxide based on the activity level of the physical quantity.
The method is divided into three levels, namely a method 1, a method 2 and a method 3 according to different adopted emission factors and parameters.
Each method is specifically described below:
method 1 is an accounting method based on fuel consumption and default factors and parameters for the source category, the calculation formula is:
i represents the fuel variety, i.e. the ith fuel;
Eburning ofIndicating the amount of greenhouse gas emissions resulting from combustion;
ADidata representing activity levels corresponding to the ith fuel;
EFiindicating the corresponding emission factor of the ith fuel;
the AD mentioned aboveiAnd EFiAll can be queried by querying standards issued by the relevant entity or in guidelines;
the sum of the emission amounts of the 1 st to the nth fuels is shown, and n is the total number of fuel varieties.
In the present embodiment, after the standard discharge amount and the reference discharge amount are obtained by the two methods, respectively, the two may be compared.
And 104, if the difference value between the standard discharge amount and the reference discharge amount is larger than a preset threshold value, adjusting the reference discharge amount, and inputting the adjusted discharge amount into a discharge monitoring system.
In this embodiment, if the difference between the standard discharge amount and the reference discharge amount is greater than the preset threshold, the reference discharge amount may be adjusted and corrected according to the actual situation, and the adjusted discharge amount may be input to the discharge monitoring system.
In some optional implementations of this embodiment, the emission monitoring system is communicatively coupled to a plurality of emission control systems within the target area, wherein the plurality of emission control systems control the operation of the emission, the method comprising: the emission monitoring system stores a plurality of historical emission amounts in a historical time period, compares the input emission amount with the historical emission amount, pushes early warning information to a terminal in a target area if the input emission amount is larger than the historical emission amount and the difference value is larger than a preset threshold value, and sends an emission stopping instruction to the emission equipment control systems to stop the emission of the emission equipment.
In some alternative implementations of this embodiment, the emissions monitoring system is communicatively coupled to a plurality of greenhouse gas treatment device control systems within the target area, the plurality of greenhouse gas treatment device control systems controlling the operation of a plurality of greenhouse gas treatment devices, the method comprising: the emission monitoring system stores a plurality of historical emission amounts in a historical time period, the input emission amount is compared with the historical emission amount, if the input emission amount is larger than the historical emission amount and the difference value is larger than a preset threshold value, early warning information is pushed to a terminal in a target area, and an instruction for representing accelerated processing of greenhouse gases is sent to a plurality of greenhouse gas processing equipment control systems, so that the plurality of greenhouse gas processing equipment are in full-load operation.
