The Closed Pressure Relief System is a system for the collection of vapor and gas discharges from pressure relief valves, vapor depressuring valves, unit pressure control vents, and onsite liquid knockout drums.  The system contains pressure relief valve leads, laterals, unit headers, main headers, flare knockout drum, flare header, flare stack, and flare tip.
