ULTRALIGHT SURFACE-ACTIVE SYSTEMS FOR PREVENTING LIQUID HYDROCARBONS EVAPORATION

Evaporation from the surface of hydrocarbon liquids without cover, at applying native glass microspheres cover, and coated with ultralight surfactant system including microspheres has been investigated. A series of ultralight surface-active systems that interact with the surface of the microspheres and prevent evaporation of hydro-carbon liquids by 98-99.6 % has been developed. For the first time it was found that native gas-filled glass microspheres of low density (200-410 kg/m(3)) while providing excellent buoyancy do not protect but increase the evaporation of individual saturated hydrocarbons of homologous series C-5-C-10.
