Gas flaring is not only necessary in the Oil & Gas industry, but also at some chemical and petrochemical facilities, like ethylene or olefins plants.
Nowadays, this industry is taking serious efforts to reduce this occurrence.
The aim is not only to help reduce emissions of air pollutants, noise and light coming from flare stacks, but also to recover usable resources.
Moreover, in some countries, the regulations on the GHG emissions or the so-called carbon taxes are bringing operators to think about unnecessary gas flaring.
For all these reasons, it is easy to understand that it is convenient to recover rather than burn the flare gases.
