Why is acidic water injected into the catalytic unit stabilization system?
It is mainly used to wash acidic media and reduce corrosion
It is mainly to prevent low-temperature dew point corrosion caused by sulfides.
The purpose of injecting acidic water is to wash away hydrogen sulfide, partly in order to reduce corrosion； On the other hand, to reduce the costs of alkali washing for stabilized gasoline.
