The losses from evaporations is the way for quality losses

Abstract

Purpose. Nowadays constant expansion of transport sector is observed. As a result, the level of environment pollution with harmful hydrocarbon transport emissions is constantly increased. This has caused the increasing of European requirements both to used fuel quality and the standards of fuel emissions into the atmosphere. The basic sources of hazardous emissions are: emissions of hydrocarbon vapors fuels during transportation, storage, implementation of different technological operations, as well as products of fuel combustion. The level of vehicle environmental safety depends on quality of used fuel. Taking into account given circumstances the purpose of the article is the study of correlation between losses of motor gasoline from evaporation and possible negative changes of their physical and chemical, operating and environmental properties. Methodology. Standard methods of control of gasoline quality and monographic method. Findings. The interaction between losses from evaporation and standard of fuel is considered in the article. The results of research of physical and chemical and operating properties changes of motor benzine conditioned by evaporation are presented. The analysis has showed the dependence of motor benzine standard on quantitative losses from evaporation. Originality. Solving of important ecologic and energetic problem by preventing the losses of gasoline from evaporation. Practical value. The petroleum sector plants should be equipped with modern facilities for prevention of motor gasoline evaporation losses in order to minimize negative influence on the environment, as a result of both harmful hydrocarbon vapors emissions of gasoline (during storage, transportation and implementation of technological operations) and fuel use, which have undergone the negative changes of quality in consequence of evaporation.
