The aim of this work is to consider and identify the best way for gas recovery to achieve the highest flaring system efficiency. This case can be accompanied by an overview and study of the gas flaring and flaring system in the petroleum industry. The significance of this study in various petroleum positions as a general and, in particular, in established projects such as refining corporations, given the high income of gas as proven by World Bank. The World Bank reports from July-2020 that between 150 and 170 billion m3 of gasses are flared or sold annually. Therefore, there is an urgent need to measure flared gas by its known composition, distribution, and volume, as well as by applying an appropriate flaring gas recovery or disposal system.
