The reference answer can be seen after *responding*; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) Monitoring the pressure drop in the reactor allows for timely assessment of the clogging status of the catalyst bed inside the reactor, providing a basis for shutting down the plant for maintenance. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Third Phase of HaiChuan’s Outstanding Management Members Selection Contest http://bbs.hcbbs.com/thread-1655902-1-1.html (Source: HaiChuan Chemical Forum)
It is possible to promptly understand the degree of blockage in the catalyst bed inside the reactor, providing a basis for shutting down the plant for maintenance.

Pressure drop refers to the pressure decrease as reactants pass through the reactor; a higher value indicates greater resistance in the reactor bed. Thus, the pressure drop can be used to check whether there is any blockage in the reactor bed, thereby allowing an assessment of the operating conditions of the bed.

Monitoring the pressure drop in the reactor reflects the degree of bed blockage, providing support for long-term operation
The degree of coking of the catalyst can be predicted

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, breakdown of catalyst particles, and blockage by impurities. To keep track at all times of the extent of coking, scaling, catalyst crushing, and impurity blockage in the catalyst bed, it is necessary to monitor the pressure difference at the reactor outlet as well as between the upper and lower beds. This facilitates proper analysis of the causes, the implementation of corrective measures, and an understanding of the device’s operational cycle.
