With the rapid development of society, the global warming problem is becoming more serious, green energy sources such as methanol, ammonia and hydrogen are widely produced in order to seek more efficient, green, low-carbon and sustainable economic development means, emission reduction standards for enterprises in the process of producing energy sources are becoming higher and higher, and the demand for carbon investigation for enterprises in the process of producing energy sources is also rapidly increasing. The energy produced at different stages has different carbon emission standards, so that the determination of the actual production time of the energy is particularly important. From the current state of carbon inspection, the actual production time of the energy is not confirmed, so that the judgment result of the green production process of the energy is deviated, and accurate guidance is difficult to provide for enterprises.
Referring to fig. 1, the present application provides a method for determining green production process of energy, the method comprising:
s101, calculating the total carbon emission E in the energy production process.
It will be appreciated that greenhouse gases are emitted during the production of energy, the total carbon emissions E being the total amount of greenhouse gases emitted during the production of energy.
Alternatively, the energy source may be one of a gas energy source, a liquid energy source, a solid energy source, or the like.
It is understood that greenhouse gases include, but are not limited to, carbon dioxide, nitrogen dioxide, and the like.
S102, acquiring a reference emission EF of greenhouse gases in the energy production process;
It will be appreciated that the baseline emissions of greenhouse gases in the energy production process may be the total emissions EF of using fossil fuels to produce energy. The fossil fuel may be, but is not limited to, coal, oil, and natural gas.
It will be appreciated that the value of the reference emission EF of greenhouse gases in the energy production process is regarded as the reference emission.
And S103, calculating the emission reduction rate P in the energy production process according to a formula P= (EF-E)/EF.
As will be appreciated, the emission reduction rate P is a measure of the percentage of reduction in the total amount of greenhouse gases emitted during the energy production process relative to a baseline emission. The larger the value of the emission reduction rate P is, the better the emission reduction effect in the energy production process is.
S104, acquiring the actual production time of the energy source, and acquiring a target emission reduction rate threshold P' of the time period according to the actual production time.
S105, if P is more than or equal to P', judging that the energy production process is a green production process; if P is less than P', judging that the energy production process is a non-green production process.
The method for determining the green production process of the energy source is used for determining whether the production process of the energy source is the green production process, and the emission reduction rate P in the energy source production process is obtained by comparing the total carbon emission in the energy source production process with the reduction value of the standard emission of greenhouse gases in the energy source production process. According to the judging method, the most accurate actual production time of the energy is determined, so that the green judgment is carried out on the energy production process. Further, if P is greater than or equal to P ', it is indicated that in the process of producing energy, the total carbon emission in the process of producing energy is reduced to a larger extent than the reference emission of greenhouse gases in the process of producing energy, so that the emission reduction rate P in the process of producing energy is greater than the target emission reduction rate threshold P', and the process of producing energy is judged to be a green process. If P is smaller than P ', the method indicates that the reduction amplitude of the total carbon emission in the energy production process is smaller compared with the standard emission of greenhouse gases in the energy production process, so that the emission reduction rate P in the energy production process is smaller than the target emission reduction rate threshold P', and the energy production process is judged to be a non-green production process. In the determination method provided by the embodiment, the actual production time obtained by the determination method is used for accurately obtaining the target emission reduction rate threshold value of the stage where the energy production process is located, so that the green determination is performed on the green production process of the energy, the obtained target emission reduction rate threshold value is prevented from being wrong due to the fact that the actual production time of the energy is wrong or deviates from reality, the accuracy of green determination is improved in the production process of the energy, and more accurate results are provided for enterprises.
Referring to fig. 2, the obtaining the actual production time of the energy includes:
S201, obtaining the standard production ratio of the energy.
It is understood that the energy production ratio is the ratio of the raw material usage amount to the yield in the process of producing energy.
It will be appreciated that the ratio of raw material usage to yield of the energy source is in a constant range during the actual production phase of the energy source, and that the standard production ratio is an average of a plurality of production ratios during the actual production phase of the energy source.
S202, obtaining a first production ratio of the energy source in a first preset stage.
It will be appreciated that the larger the first production ratio, the more raw materials are used to produce unit energy.
S203, when the difference value between the first production ratio and the standard production ratio is larger than a first preset value, judging that the first preset stage is in a test operation stage; and when the difference value between the first production ratio and the standard production ratio is smaller than or equal to a first preset value, judging that the first preset stage is in the production stage.
It can be understood that from the commissioning phase to the production phase, under continuous debugging, the production ratio shows a gradually decreasing trend and gradually becomes stable.
It can be understood that in the commissioning phase, the energy production process is not debugged to a better state, and the production is relatively large, i.e. the raw materials used for producing the unit energy are relatively large.
It is understood that the first preset value is the greater one of the maximum value of the production ratio and the difference of the standard production ratio, and the minimum value of the production ratio and the absolute value of the difference of the standard production ratio in the actual production stage of the energy source.
S204, obtaining a second production ratio of a second preset stage.
It can be appreciated that if the first preset phase is in a commissioning phase, the second preset phase follows the first preset phase; if the first preset stage is in the production stage, the second preset stage is before the first preset stage.
S205, when the first preset stage is in a test operation stage and when the difference value between the second production ratio and the standard production ratio is smaller than or equal to a first preset value for the first time, judging that the second preset stage starts production, and acquiring the first time when the energy starts production; when the first preset stage is in the production stage and when the difference value between the second production ratio and the standard production ratio is larger than a first preset value for the first time, judging that the second preset stage is ready to enter the production stage, and obtaining the first time when the energy starts to be produced.
It can be appreciated that, when the first preset stage is in the commissioning stage, the first production ratio of the first preset stage is greater than the standard production ratio and the difference between the first production ratio and the standard production ratio is greater than the first preset value, and the second preset stage is a cyclic process after the first preset stage, until the difference between the second production ratio of the second preset stage and the standard production ratio is less than or equal to the first preset value for the first time, it is determined that the second preset stage starts to produce, and the initial time point of the second preset stage is the first time when the energy starts to produce.
It may be appreciated that, when the first preset stage is in the production stage, a difference between a first production ratio of the first preset stage and a standard production ratio is smaller than a first preset value, and the second preset stage is a cyclic process before the first preset stage, until a difference between a second production ratio of the second preset stage and the standard production ratio is larger than the first preset value for the first time, it is determined that the second preset stage is ready to enter the production stage, and an end time point of the second preset stage is a first time when the energy starts to be produced.
S206, determining the actual production time according to the first time.
In this embodiment, in the actual production stage of the energy source, the ratio of the raw material usage amount to the yield is in a constant range, and the ratio of the raw material usage amount to the yield of the energy source in the actual production stage is higher than that in the commissioning stage. According to the judging method provided by the embodiment, the first preset stage is obtained, the first production ratio of the first preset stage is calculated and compared with the standard production ratio, so that the first preset stage is judged to be in the test running stage or the production stage, and an instruction is provided for the drawing of the second preset stage. If the first preset stage is in the test operation stage, part of the time after the first preset stage is circularly taken as a second preset stage, and the ratio of the raw material usage amount to the yield of the second preset stage is calculated until the difference value between the second production ratio of the second preset stage and the standard production ratio is smaller than or equal to a first preset value for the first time, so as to judge that the second preset stage enters the production stage from the test operation stage, and judge that the initial time point of the second preset stage is the first time when the energy source starts to produce. Similarly, if the first preset stage is in the production stage, a part of the time before the first preset stage is circularly drawn as a second preset stage, and the ratio of the raw material usage amount to the yield of the second preset stage is calculated until the difference between the second production ratio of the second preset stage and the standard production ratio is larger than the first preset value for the first time, so as to judge that the second preset stage enters the production stage from the test operation stage, and judge that the ending time point of the second preset stage is the first time for starting production of the energy source. According to the judging method of the embodiment, through the mutual matching of the first preset stage and the second preset stage, the critical value of the trial operation stage and the production stage is obtained in a continuous approximation mode, so that the first time is obtained, and the actual production time of the energy source is determined according to the first time. Compared with the method for obtaining the actual production time directly through the basic data provided by the enterprises, the method for judging the energy source production time can obtain the actual production time of the energy source more accurately from the result guide, so that the carbon emission standard of the stage of the energy source production process can be conveniently determined, more accurate basis is provided for judging the green production process of the energy source, and more accurate result is provided for the enterprises.
Alternatively, the energy source may be, but is not limited to, one of methanol, hydrogen, and the like.
Optionally, the first preset stage is any stage of the energy production process, and the duration of the first preset stage may be adjusted according to practical situations, where the duration of the first preset stage is 0.5 to 60 days, specifically, the duration of the first preset stage may be, but not limited to, 90 days, 60 days, 30 days, 15 days, 10 days, 3 days, 1 day, or 0.5 day, etc.
In this embodiment, the duration of the first preset stage may be adjusted according to the actual situation, and it may be understood that, when the duration of the first preset stage is shorter, in the method for determining the actual production time of the energy, the number of cycles is greater when the second preset stage is obtained and the second production ratio of the second preset stage is calculated, so that the final obtained result of the first time when the energy starts to be produced is more accurate, which is favorable for providing more accurate actual production time for enterprises. However, correspondingly, the duration of the first preset stage is too short, and the more the number of times the determining method needs to be cycled in the determining process, the more difficult the data processing is.
Optionally, the duration of the second preset stage is equal to the duration of the first preset stage.
In this embodiment, the duration of the first preset stage is equal to the duration of the second preset stage, so that the obtained first time is prevented from deviating from the actual production time by too much due to the difference between the duration of the first preset stage and the duration of the second preset stage, which is beneficial to improving the accuracy of determining the actual production time of the energy source by the determination method.
Referring to fig. 3, in some embodiments, the determining the actual time to put into production according to the first time includes:
s301, acquiring preset production time of energy.
Optionally, the preset production time of the energy source can be obtained by obtaining basic data, such as a construction schedule.
