Abstract:
Systems and methods for reducing atmospheric emission of hydrocarbon vapors by flashing off hydrocarbon vapors in an overflow drum where the pressure is ultimately reduced to 0 psig and then flashing off any remaining hydrocarbon vapors in an overflow tank wherein the pressure in the overflow tank is reduced to 0 psig by an overflow ejector.

Claim (Index 1):
A system for reducing atmospheric emissions of hydrocarbon vapors in a delayed coke drum quench overflow system, which comprises:\n an overflow drum connected to a blowdown header line for reducing hydrocarbon vapors and producing a vapor overflow remainder and a liquid overflow remainder; an overflow tank, connected to the overflow drum by a liquid overflow remainder line, for separating at least one of skim oil, water, coke fines, and tank vapor from the liquid overflow remainder; and a tank vapor line in fluid communication with the overflow tank for transmitting the tank vapor to an overflow ejector, wherein the overflow ejector includes an inlet in fluid communication with the tank vapor line and an outlet in fluid communication with a steam line for reducing the pressure in the overflow tank to 0 psig.
