Prediction of storage pressure of gasoline in uninsulated tanks

A design working pressure of any storage tank can be determined to prevent breathing, and thereby save standing storage losses. However, this should not be used in lieu of any environmental regulatory requirements regarding the design of storage tanks. The environmental regulatory requirements for the specific location should be consulted before the design of storage facilities. Generally, there are regulatory requirements specifying the type of storage tank to be used, based on the storage tank capacity and the vapour pressure of the product being stored. In addition, there are usually specific design requirements, for example in the type of seals to be used in a floating roof tank. The working pressure required to prevent breathing losses depends upon the vapour pressure of the product, the temperature variations of the liquid surface and the vapour space, and the setting of the vacuum vent.
