Systems and methods for safe on-line pigging decoking of a coker furnace tubes and which also permits on-line spalling operations.

Systems and methods for on-line pigging and spalling of coker furnace outlets

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.

Delayed coke drum quench systems and methods having reduced atmospheric emissions

An efficient delayed coking process improvement for producing heavy coker gas oil of sufficient quality to be used as hydrocracker feedstock.

Efficient method for improved coker gas oil quality

Delayed coking drum quench overflow systems and methods, which relate to removing hydrocarbon particulates from an overflow stream in a delayed coking drum quench operation. In one embodiment, an improved overflow system incorporates one or more filters to remove hydrocarbon particulates from the system before passing through a conventional closed blowdown system.
