Individual Pressure Relief Load: The maximum pressure relief discharge rate from a particular piece of equipment for a single contingency used for sizing a pressure relief device and its inlet and outlet piping and to determine the cumulative load for a scenario for sizing flare header laterals and main headers and the flare knockout drum and flare tip.

Maximum Emergency Relief Load: The maximum relief discharge rate to the flare.  The maximum relief load is the larger of the largest individual relief load or the simultaneous opening of a number of pressure relief devices because of power failure or similar scenarios.  It is used for calculating sizes of the headers, flare stack, knockout drum, or seal and flare tip.
