Reaction pressure drop
Thread Content
What are the effects of a high pressure drop in the reaction system?
The most serious issue is that it makes it difficult to control the bed temperature; the temperature can fluctuate easily, which may lead to surging in the recycle hydrogen compressor and force the installation to shut down
This leads to increased energy consumption and raises the loading on the internal components of the reactor. At what pressure difference between the inlet and outlet of a severe cycle compressor should it be shut down?
It leads to increased energy consumption; in severe cases, it can even collapse the reactor bed, and if it gets worse, operations have to be halted
Why is it difficult to control the temperature?
The pressure drop is high, which may lead to the formation of hot spots. The presence of such hot spots causes an increase in catalyst carbon deposition, increasing the risk of overheating
