Determination of emissions of vapor of technic flammable liquids from enterprise for their storing and distribution and rational ajustments of their breathing valves

Abstract

In this study, generally devoted to increasing the level of ecological safety of the exploitation process of reusable reservoirs for storing flammable technical liquids for the enterprise for the storage and distribution of petroleum products as part of the appropriate environmental protection technology, the parameters of such liquids stored in reservoirs of the enterprise, and technical indicators of reservoirs for their storage according to the developed method. Methods for determining the magnitude of the mass hourly emission of vapours of such liquids, caused by the phenomena of small and large breathing of reservoirs, as well as the total emission by both mechanisms, taking into account the daily values of the atmospheric temperature difference and the degree of filling of the reservoir, have been improved and described, and the results of the corresponding computational research. A calculated study of the effectiveness of the use of a breathing valve to reduce the emission of vapours of technical flammable liquids from reservoirs for their storage by the mechanism of small breathing and justification of the choice of setting the tightening of its spring has been carried out. A list of recommendations has been formulated to improve the ecological safety of the exploitation process of reusable reservoirs for storing liquids, the vapours of which are toxic, fire and explosive, greenhouse and energy-intensive pollutants
