چکیده:

Volatile organic compounds (VOCs) emitted from storage facilities play a key role in forming ground-level ozone, which causes breathing problems for humans and damages plants. In this paper, the amount of the Volatile Organic Compounds (VOCs) which is emitted from an industrial external floating roof tank is estimated practically and also by using the relations which are proposed by American Petroleum Institute (API). For this purpose the level of the considered liquid in the tank and its temperature are monitored and recorded for a period of 35 days. Comparison of the obtained practical data with those predicted by API relations under the same operating, geographical and meteorological conditions, shows that the practical data are higher than predicted values. These results in those same actions should be measured to lower the rate of emission of VOCs from the tank by improving the seals or considering the problem of seepage from the tank.
