Storage tank models



Storage vessels containing organic liquids can be found in many industries (petroleum producing and refining, petrochemical and chemical manufacturing and other industries consuming or producing organic liquids).

Six basic tank designs are used for organic liquid storage vessels:

Emissions from organic liquids in storage occur because of evaporative loss of the liquid during its storage and as a result of changes in the liquid level. The emission sources depend on tank design and stored products.

The different standard models in that section (to be developed) can be use for estimating atmospheric vapour losses from fixed roof, external floating roof, domed external floating roof, and internal floating roof tanks.

These procedures are valid for all petroleum liquids, pure volatile organic liquids, and chemical mixtures with similar true vapour pressures.
