Flare Systems - Purpose
A system of Process Safety Management (PSM) critical
mechanical equipment that gathers and safely burns
hydrocarbons from pressure-relieving and vapordepressurizing
systems
Must be continuously available
Must be reliable for years
Capable of performing through all operating-plant
emergency conditions, including a site-wide general power
failure or a weather event including a hurricane
Difficult to add equipment or modify because they are very
infrequently out of service as they serve many units that
are infrequently out of service.
