Abstract

Currently, the most common way to reduce hydrocarbon losses from evaporation at oil and petroleum products storage facilities is to use pontoons and floating roofs. However, vapour recovery systems can achieve a greater degree of loss reduction. Membrane vapour recovery units, that are widespread in Europe, are still not in use in Russia, although their high effectiveness is noted in some sources. Another promising way to reduce losses is to use ejector vapour recovery units. The article substantiates the use of combined membrane-ejector vapour recovery units: a methodology for calculating the effectiveness of such devices is proposed and an analysis of the influence of various parameters of membrane-ejector systems on the degree of reduction of gasoline losses during oil tank filling is made.
