Control of product quality

This can be determined based on the test analysis data, as well as by considering the properties of the crude oil to estimate the appropriate operating temperature.

This should be handled based on the laboratory data, right?

Generally, it is determined based on operational experience, as there are many factors at play, and it’s not possible to use a fixed formula to calculate the result. The simplest approach is to adjust according to the results of laboratory analyses, which is both more accurate and more convenient.

In fact, advanced control systems can calculate certain data for reference, but when it comes to catalysis, the regeneration system is quite complex, resulting in slightly lower accuracy in the simulation of this aspect.

First, you need to create a curve showing the changes in pressure and temperature; thereafter, it’s possible to determine the corresponding temperature value at any given pressure. However, the temperature of the final product is usually determined by the manufacturing process! Quality issues and products that do not meet standards also require further analysis!

The method mentioned by the original poster can be implemented in three ways: First, use an APC remote control on the device； There are two types of online control. One type involves online analysis of the gasoline distillation range and control of the tower top temperature through series connection; the other type controls the tower top temperature through simulation calculations. The second type deviates more from the first one and thus requires maintenance. But the first option requires investment in equipment ； Second: A data point is calculated through artificial simulation, using DCS values; this data point serves as a guide for adjusting the set points through fixed-point calculations ； Third: laboratory analysis or manual calculation by the operator, but it is usually laboratory analysis. In summary: laboratory analysis is the ultimate goal. It is also the most illustrative. All other methods are merely means.

Through laboratory data analysis, or through APC regulation
