Floating roof storage tanks.

Various aspects of the floating roof tank working like the operation.
The roof rises and falls with the liquid level in the tank.
Today controlled gas venting in to the atmosphere is becoming more and more important due to environmental regulations.
However by reducing emissions the increased costs can be offset or justified on the basis of reduced product loss though evaporation a product savings and less impact to the environment.
The floating roof tank animation describes the working principle in the training module.
