EVALUATION OF THE EFFECTIVENESS OF POWDER COMPOSITIONS FOR CREATING INSULATING LAYERS ON THE SURFACE OF SPILLED LIQUEFIED NATURAL GAS

The conducted laboratory studies confirmed the high efficiency of the developed method for reducing the evaporation rate of liquefied natural gases. The use of liquid nitrogen as a safe model substance provided reliable quantitative assessments of evaporation dynamics without risk to the researchers. The experiments established that the application of basalt fabric with deposited powder coatings significantly reduces the heat flux to the surface of the evaporating liquid, creating an additional thermal insulation barrier. This, in turn, reduces the formation of flammable vapor-air mixtures and lowers the probability of their ignition in emergency situations. A promising direction for further research is the optimization of the powder material composition to enhance their thermal insulation properties and resistance to various operating conditions. The development of the proposed technology will open up opportunities for creating more effective and affordable methods for emergency liquefied natural gases spill response, which will contribute to a significant increase in the level of industrial safety during the transportation and storage of liquefied gases.
