Hydrogen
Water is injected upstream of the Naphtha Hydrobon Fin-Fan Condensers to?
Prevent salt from plugging the fin-fan tubes.
The Hydrogen Supply to the Naphtha Unit normally comes from the?
CCR Unit.
Filmer is injected into the Naphtha Hydrobon to?
Provide a protective coating on the metal surfaces to reduce corrosion.
To what location does the off gas from the Naphtha Stripper OVHD Receiver go?
To a Hydrobon Amine Fuel Gas Absorber.
What vessel/vessels require manual draining in the Naphtha Unit?
The Naphtha Stripper OVHD and the Naphtha KO Drum.
Where is the rip cord located to rapidly depressure the Naphtha Unit to the flare?
Southwest end of the Naphtha Product Separator.
Where does the Naphtha KO Drum drain to?
The Naphtha Stripper Feed.
