【Daily Question No. 337】December 09, 2018: Please explain why it is necessary to monitor the pressure drop across the reactor bed Because the bed pressure drop in the hydrorefining reactor is not only an important design parameter but also sometimes becomes a limiting factor for the long-term operation of the plant. An increase in the bed pressure drop not only leads to higher energy consumption but, more importantly, increases the loading on the components inside the reactor. In severe cases, this leads to an excessive pressure difference between the inlet and outlet of the cyclohydrogen compressor, forcing it to shut down. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Monitor reactor coking and flow deviation conditions
The bed pressure drop in the hydrorefining reactor is not only an important design parameter but sometimes also becomes a constraint on the long-term operation of the plant
Fluctuations in pressure drop reflect whether the feed rate is normal or not
This is used to determine the distribution of the reactive oil and gas, whether coking has occurred at the top of the catalyst (in the fouling basket) and to what extent, to decide whether it is necessary to shut down the system for cleaning. Furthermore, excessive pressure drop can damage the structure of the catalyst carrier (causing it to break apart), which in turn increases the pressure drop within the bed

An increase in the bed pressure drop not only leads to higher energy consumption but, more importantly, increases the loading on the components inside the reactor.
