The basic system of gasoline vapour recovery unit works on the principle of Pressure Swing Adsorption (PSA). The PSA system consists of two carbon vessels to ensure continuous operation.

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.

Salient Features

  • Removal upto 99.98% of Hydrocarbon content from the exhaust air.
  • Elimination of gasoline vapour from the exhaust air prevents health hazards.
  • Minimization of fire or explosion risk due to reduced Hydrocarbon vapour in atmosphere.
  • No generation of pollutant during operation.
  • Economic benefits from recovered gasoline.
  • Custom designed to suit specific needs.
  • Compact design with ease of maintenance and transportation.
  • Skid mounted design reduces civil / erection cost.
  • System designed with only electricity as utility.
  • Operation fully automatic.
