ABOVE STORAGE TANK DEGASSING

Degassing of Above Storage Tanks  
  • NanoVapor suppression was used to successfully degassed a total of six (6)  gasoline and one (1) Diesel tank between 2500 and 5000 m3.  

  • The prior method of degassing involved the use  of water-washing to degas their tanks to 10% LEL.

  • This method would generate  5,000 liters of contaminated waste-water per tank, which must be held in storage and later hauled away to be remediated. This represented considerable time and cost, as well as a logistics bottleneck.

  • In contrast, NanoVapor produced a time savings of up to 44% in degassing to 10% LEL for tank entry, completely eliminating the time, cost, and logistical issues related to the contaminated waste-water .

  • NanoVapor was used to quickly achieve and maintain the 0% LEL atmosphere required to safely perform hot work, and the 0% LEL safe atmosphere persisted for two (2) more days without any re-application of NanoVapor suppressant.
