Coke drum and blowdown system overpressure protection design - Part 1

The blowdown (BD) system in delayed coking units (DCUs) receives waste streams generated during the coke drum (CD) decoking process to recover valuable hydrocarbons and water. In recent DCU designs, the CD pressure relief valves (PRVs) also discharge to this system and then to the flare system via the BD PRVs.
