VOC emissions from external floating roof tanks: comparison of remote measurements by laser with calculation methods

Report no. 95/52: Hydrocarbon emissions from storage tanks are normally calculated using procedures published by the American Petroleum Institute. A laser-based technique has been used to measure remotely the emissions of hydrocarbons from floating roof tanks.

The measurements obtained have confirmed the accuracy of the recently updated API estimation method for external floating roof tanks. The ability of the remote measurement technique was demonstrated by comparison with direct measurements of emissions during the loading of a barge.
