Calculation of Nitric Oxide Oxidation Rate
Thread Content
If the nitric oxide oxidation rate is not looked up in the table, is there a better way to solve it besides the split-and-half method? There is also the problem of how to select the initial interval in this method. Let’s discuss how to quickly solve this problem in practice.
You can check the nitric acid in the Nitrogen Fertilizer Process Design Manual* The ao acid an part has detailed calculation formulas
After checking, there are certain prerequisites for its application, but to obtain the oxidation rate, it is more troublesome to solve. The look-up table method is often used, but this method cannot be written into a program and cannot be analyzed. Only suitable data information can be established and read out using the difference method.
The icons on the "Nitrogen Fertilizer Process Design Manual" are accurate and intuitive to read, but they are not good for calculations of optimal control plans for the construction of existing process flows. I don't know how everyone can get the precise values of oxidation rate and reaction rate constants without looking up tables in reverse design calculations. I also checked that the calculation formulas 1-2-69 and 1-2-70 on page 47 of the "Nitrogen Fertilizer Process Design Manual" are very accurate, but does the range of oxidation rate need to be determined based on statistical rules when starting the calculation? Is it difficult to implement split-and-half calculation on the lower computer (because it is mostly a given software platform, such as ICS, etc.)? I don’t know if anyone has experience in this area, please feel free to enlighten me, thank you.
In addition, there is a big difference between the formula log (kp) = 641/T-0.725 for calculating the reaction constant in the Soviet data mentioned above and the value obtained from the table. How did you solve this problem in the design? Thanks!
The actual method of using a look-up table is relatively simple, but it requires actual correction. After all, it is all empirical data, and it is mostly explored and verified on industrial devices.
Thanks for the poet's advice, I will try my best. At the same time, recent calculations have found that the theoretical calculation of automatic control research according to the design idea is actually very difficult, because the parameters required for control generally need to be processed all the time, and it is impossible to look up tables. It is best to have similar empirical formulas, starting from the explicit relationship between variables and independent variables. Of course, given the data table, it is theoretically possible to read the difference. I wonder if anyone has experience in this area that can be discussed. Thank you again.
This formula comes from some Soviet material?
