【Q&A Question 109】August 07, 2016: What is the significance of monitoring the pressure drop in a reactor? The answer key can be seen after responding; scoring is based on identifying the key points. The greater the pressure drop, the greater the resistance, which causes damage to the reactor; channeling is likely to occur in the catalyst bed. The fluidization state of the catalyst can be determined by the pressure drop.
Check the carbon deposition on the catalyst inside the reactor
First, the reactor pressure difference is one of the important control parameters. Secondly, the pressure drop in the reactor allows for better observation of the changes inside it. Third, when the pressure drop exceeds the allowable range, it indicates that there is a problem with the catalyst; in such cases, operations should be stopped and the catalyst replaced to better protect the equipment and personnel.
It is possible to infer the coking condition of the catalyst
It is possible to check whether the bed layer has sintered and whether the catalyst is still active.
Use the pressure drop to check whether there is any blockage in the reactor bed.
Detect the carbon deposition on the catalyst to reflect its activity
If the pressure drop is high, the circulating hydrogen bypass can be adjusted to save energy and reduce consumption. It is possible to stop work, turn it over, and replace the protective agent.
The presence of blockages in the reactor bed can be checked by measuring the pressure drop.
The clogging condition of the pressure drop reaction reactor,
