In a refinery, Crude Oil is received and stored in a Floating Roof Tank. The Roof is made of compartmented deck or Pontoon floating over the Oil to avoid loss of Hydrocarbon Vapours of dissolved Hydrocarbon Gases and low boiling fractions present in Crude Oil. The Floating Roof also floats up and down to compensate for the breathing operations during pumping in and out of the Tank thereby safeguarding the loss of Vapours and ingress of Atmospheric Air into the Tank.
