Typical flare system in industrial plants
Diagrammatic representations of a typical vertical, elevated flare stack system in an industrial plant. During operations, when industrial plant equipment items are over-pressured, the pressure relief valve is an essential safety tool that automatically releases gases and sometimes liquids. Those pressure relief valves are essential by industrial design codes and standards as well as by law. The released gases and liquids are directed through large piping systems known as flare headers to a vertical elevated flare. The escaped gases are burned as they exit the flare stacks. The size and brightness of the resulting flame is determined by the flammable material's flow rate in joules per hour (or btu per hour). Majority of industrial plant flares have a vapour-liquid separator(also called a knockout drum) upstream of the flare to remove any large amounts of liquid that may go along with the relieved gases. Steam is f...
