Pressure Relief Equipment and Flare System

A number of key terms associated with separation include  

Pressure relief equipment includes relief valves, safety valves, rupture discs, piping, drums, vent stacks, pressure indicators, pressure alarms, pressure control loops, and flare systems. Process equipment is typically rated for specific pressure and temperature ranges. Engineering specifications 

Flare systems are part of a plant s safety system. Most process units are aligned to safety relief valves that lift when specified pressures are exceeded. These safety valves discharge into the flare header. Unexpected process upsets are dumped to the flare system as a last course of action. A typical flare system includes  

Flare—a long narrow pipe mounted vertically 

Steam ring—mounted at the top of the flare used to disperse hydrocarbon vapors Ignition source—located at the top of the flare
