Operation issues after Fcc cutting
Thread Content
After stopping the FCC feed, how should the steam for pre-raising, raw material atomization, and gas vapor be adjusted? Who gets priority to use the ultimate ability? I hope to receive guidance from all the teachers. Thank you!
After the feed system is secured, the pre-lift steam valve and the raw oil atomization steam valve are kept in the fully open position. The stripping steam valve is generally not opened further. If it is necessary for one of these three valves to be opened wider, then it should be the raw oil atomization steam valve, in order to prevent clogging of the nozzles
The crude oil nozzle shouldn’t get clogged that easily, right?
