Modern methods for reducing evaporation when storing petroleum products in tanks

Abstract

The given article considers the problem of evaporation that becomes relevant with long-term storage of petrol in large-capacity tanks. Evaporation of oil products leads to a change in their physical and chemical properties. As a result of evaporation, the amount of light oil products is reduced. It leads to deterioration in engine performance. In this regard, it is difficult to start engines as fuel consumption increases and the service life is reduced, the fire hazard increases. Vaporizing light hydrocarbons pollute the environment. The purpose of this work is to identify effective, inexpensive and safe methods for reducing the evaporability of petroleum products, including gasoline when stored in tanks. Use of chemical additives as an inexpensive and efficient method of solution of gasoline evaporation problem is considered. The conclusion about the effectiveness of using chemical additives to fuels to reduce evaporability is justified. Conclusions have been drawn about the possibility of using surfactants as additives to reduce the evaporation of gasoline during long-term storage in tanks. Analysis of the main components and methods of synthesis of surfactant compositions capable of creating a film of surfactant at the liquid-atmosphere interface, protecting the liquid from evaporation was carried out. Reducing the vaporization of gasoline using inexpensive and efficient additives introduced into the fuel in small quantities not only reduces the explosion and fire hazard when stored in the large tanks, but also prevents the environmental impact of low molecular weight hydrocarbons from entering it
