RE: Drum Cooling/Quenching


Darren Hudema

The pressure control valve I’m referring to is on the line from the top of the coke drum to our blowdown system. This pcv is normally set to 40 psig prior to starting water flow to the coker drum. During the intial water ramping the valve is almost wide open due to the large amount of steam being produce but within 2 hours the valve begins to close in order to maintain 40 pounds pressure on the drum.
