Gas flaring in oil production and oil and gas refining is a major environmental issue with great energy and economic loss. In this paper the global gas flaring and its adverse environmental impacts have been reviewed briefly. It is shown that emission factor, defined as the amount of gas flared per barrel of oil produced, varies widely among oil production sites. There is also great uncertainty in the composition of flare gases and the actual measurements are rather limited. Various available technological alternatives to reduce gas flaring are presented and compared. A special focus has been put in new technological options that still need to be developed. In addition, the best implemented projects in Iran as a major oil producing and the world’s third largest gas flaring country are presented. Finally, techno-economical constraints for gas flaring reduction have been discussed for future planning.
