Questions regarding the method of calibrating catalytic cracking units using new types of oxidizers? I have many things I don’t understand; I hope everyone will ban...

The facility has now introduced a new batch of combustion aids, and it is necessary to calibrate these new aids in order to assess their combustion-enhancing effects. The assessment is expected to take two months. Since the new type of oxidizer is produced by a different manufacturer from those that produce the previous oxidizers, the question arises: how can this new oxidizer be calibrated? There are several issues to consider now: ① Since the device has been continuously fed with the pre-combustion agent (coded as A) beforehand, how should the proportion of this agent in the catalyst system be calculated? Considering the desulfurization agent and normal catalyst loss, can we use the total amount to be added in one month divided by the catalyst inventory? Of course, this is something I’m not entirely sure about; I need to find a more appropriate method to calculate it ； ②How can the effectiveness of the newly added oxidizer (coded as B) be evaluated? The main focus is on the following data points: the temperature of the coking drum, the temperatures of the dense and dilute phases in the regenerator, and the oxygen content. Now the question is that, in my opinion, it’s really difficult to make an assessment based solely on the DCS curves; I wonder if anyone has any good suggestions? ③The effect of the original catalyst A on the combustion enhancement effect is something that must be taken into consideration. However, how should this aspect be explained in a paper or report, showing that catalyst A has a very minor impact on the new combustion enhancer B? Of course, there are other questions as well; I hope the seniors can offer some guidance~
Calibrating the effectiveness of oxidizers is quite difficult, as their main function is to assist in combustion; it essentially comes down to finding a way to use them as little as possible while ensuring that there is no residual burning behind the regenerator
Bro, you’re the moderator. . . It’s always you who replies. . . I’m so touched. . . . The same is true here; I read some papers online and felt that few of them were well-written, aside from those conducted in laboratories.
Get actively involved; there are still many experts on the forum
You must determine whether A and B are the same type of additive. First, bring up curve A and then curve B for analysis. It is necessary to fully understand B’s technical documentation
