The transfer of gasoline to truck / rail at terminals is a major source of release of gasoline vapour to atmosphere. Gasoline vapour contains aromatic hydrocarbon such as Benzene as well as aliphatic Hydrocarbons. Benzene is proved to be carcinogenic. The recovery unit drastically reduces the Volatile Organic Compound (VOC) thereby creating safe environment. It becomes economically beneficial on account of value of recovered gasoline. Drastic reduction in VOC content in air will also reduce the risk of fire / explosion.
