Abstract:
Flaring is a simple way for the disposal of gases in oil, gas and petrochemical plants where there is no infrastructure to make use of the gas. Gas flaring is widely recognized as a waste of energy. Not only that it’s an added load of carbon dioxide into the atmosphere. In the case of gas flaring, there is insufficient burning of carbon as a result of which soot and carbon-monoxides are produced, contributing to air pollution problems. Gas Flaring harms the environment and wastes a cleaner source of energy that could generate energy much needed electricity. Flare Gas Recovery (FGR) is a simple and economical method to reduce, recover and reuse gases. This paper presents a conceptual design for a flare gas recovery system (FGRS); consists of one or more compressors with suction taken from the main vent header downstream of any branch header connections. The compressed flare gas is treated for its composition and used as a fuel gas for plant heating needs; the recovered gas may be recycled back to the process or used to power generation. System operation and control, design guidelines and economics of the process have been discussed in this paper. FGRS can reduce flaring noise, operating and maintenance cost, air pollution and emission, fuel gas and steam consumption while increase process stability and flare tip life without any impact on existing safety relief system.
