The atmospheric tank is used to store produced liquids before disposal. Atmospheric tanks are manufactured for various volumes and are available as single or twin compartments. They are manufactured with the necessary inlet and outlet piping, a safety relief system, and a detonation arrestor.

Where required, the tanks have the necessary skid mounts for vertical or horizontal storage.

The atmospheric tank can be used to measure low flow rates or to calibrate flow meters prior to flowing the well.

Safety Features

Atmospheric tanks are not to be used when H2S is present, as venting to the atmosphere in the vicinity of the vessel can occur.
