Problems with residence time in oxidation rate calculation
Thread Content
There is another problem. The oxidation rate of nitric oxide is limited. The oxidation rate needs to be calculated based on the residence time. However, the temperature and pressure are changing during the chemical reaction process. According to the ideal gas equation of state, the volume of the mixed gas will also change accordingly. How to calculate the residence time more appropriately? Is it calculated according to the entrance question? Or is it calculated based on average volume?
Each unit in the chemical system must bear corresponding energy conversion and migration while reacting. Under different pressure and temperature conditions, is it reasonable to adopt an ideal state design for the gas reaction process? Can the temperature, pressure and volume flow measured during operation of the container be directly used to calculate the number of moles of the corresponding gaseous substance? Please give me your advice, or what kind of correction is needed? Looking forward to your reply and guidance, thank you in advance. :funk: :funk: :funk: :funk: :funk: :funk:
Under the specified pipeline interface conditions, the air circulation velocity actually corresponds to the volume flow rate of the process gas, which is also a changing process. If integral is used, it is obviously not suitable for engineering applications. I don’t know how everyone handles this in applications.
