Экспериментальное определение давления насыщенного пара жидких моторных топлив

Abstract

Purpose. Currently, new brands of liquid motor fuel are produced, whose fire hazardous properties are not reflected in regulatory documents and reference literature. The values of saturated vapour pressure of petroleum products presented in them differ significantly from each other and that may affect the results of assessing fire and explosion hazard of the facility under protection. The article provides the results of experimental evaluation of motor gasolines and diesel fuel saturated vapour pressure. Methods. Analytical and experimental methods for determining saturated vapour pressure of motor gasolines and diesel fuel have been used during the research process. Findings. The saturated vapour pressures of motor gasoline and diesel fuel of different brands have been determined experimentally. It has been found that saturated vapour pressure of petroleum products is different and varies over a wide range. Research application field. Experimental studies allowed obtaining the numerical value of saturated vapour pressure of currently marketed brands of liquid motor fuel. Conclusions. During the experiments, the values of the saturated vapour pressure of liquid motor fuels, significantly different from those given in the regulatory documents or determined by calculation have been obtained. The application of the obtained results will make it possible to assess fire and explosion hazard of storing flammable liquids in tank farms of the facilities under protection.
