The pressure difference in the catalytic gasoline hydrogenation reactor increases
Thread Content
I would like to ask the experts here: For gasoline hydrogenation, a staged hydrogenation process is used. The inlet pressure of the pre-hydrogenation reactor remains unchanged, while the outlet pressure continues to drop, resulting in an increasing pressure difference. At present, all process parameters are within normal ranges. What could be the possible reasons for this?

10 months after the major maintenance, gasoline is supplied directly to the filling area; the outlet pressure has been decreasing slowly for about a month, and now this downward trend has slowed down. All current parameters are within normal ranges
How long has the oil been stored in the tank area? ?
Add me on QQ; it’s too troublesome. 917832793
How long has it been running? Has the catalyst coked?
Catalyst coking; replace the protective agent； This is how we do it; it’s best to examine the design carefully to see if there are any design errors or construction mistakes ；
It is best to use direct feeding for the oil products, or the catalyst should be filled properly
