Abstract

The problem of reducing the losses of petroleum products due to evaporation, and the related problem of environmental protection are currently considered to be crucial. We have developed a new method which produces a substantial decrease in the surface evaporation rate of hydrocarbon liquids and can be used successfully instead of the traditional unreliable, bulky and expensive pontoons and condensers. The suggested method uses a lightweight powder-like material, designed to spread throughout the surface of the liquid in order to form a semipermeable layer, separating liquid and air volumes from each other. When particles produced on the basis of a sufficiently light filler (having closed-cell or closed
