【Daily Question No. 316】November 18, 2018: Why is it necessary to monitor the reactor pressure difference, and what is its purpose? Although this device strictly controls the filtration of raw materials and the temperature of the reactor, as the operating cycle lengthens, coking, scaling, and blockage by impurities can occur in the catalyst bed. To keep track of the degree of coking, scaling, and blockage within the bed at all times, it is necessary to monitor the pressure difference between the inlet and outlet of the reactor bed, as well as between the upper and lower layers of the bed. This allows for a rational analysis of the causes, so as to take measures and understand the startup cycle of the device.

Although the device strictly controls the filtration of raw materials and the reaction temperature, as the production cycle lengthens, the catalyst bed may suffer from coking, scaling, crushing of catalyst particles, and blockage by impurities. To keep track of the extent of coking, scaling, catalyst crushing, and impurity blockage in the catalyst bed at any time, it is necessary to monitor the pressure difference at the reactor outlet as well as between the upper and lower catalyst beds. This facilitates proper analysis of the causes, implementation of corrective measures, and understanding of the operational cycle of the facility.

By monitoring the differential pressure, it is possible to determine the degree of pore blockage in the catalyst, providing a reference for the operating cycle of the device
Why is it necessary to monitor the pressure difference in the reactor, and what is its purpose? Answer: Although the filtration of raw materials and the temperature of the reactor are under control, as the operating cycle lengthens, coking, scaling, and blockages caused by impurities can occur in the catalyst bed. To keep track of the extent of coking, scaling, catalyst fragmentation, and impurity blockages in the catalyst bed at all times, it is necessary to monitor the pressure difference at the reactor outlet as well as between the upper and lower layers of the catalyst bed. This enables proper analysis of the underlying issues, the implementation of appropriate measures, and an understanding of the operational lifespan of the equipment.

The pressure difference is used to determine whether there is coking or blockage inside the reactor. Of course, as the processing capacity of the unit changes, the reactor’s pressure difference will also change, but it does not keep increasing or decreasing continuously.
