As opposed to a fixed roof tank there is no vapor space in the floating roof tank except for very low liquid level situations.
Tanks with external floating roofs are used primarily to contain liquids with high vapor pressures when the vapor emissions from fixed roof tanks would exceed the standards set by the local jurisdiction.
Today the emphasis is on controlling atmospheric pollution as well as on safety.
