About new technologies and means of extinguishing hydrocarbon fluids
at oil and gas complex

      Modern methods of extinguishing oil and petroleum products are now all over the world are based on the use of mechanical foam of the non-fluorinated film-forming foam. For extinguishing fires in the storage tanks of petroleum and petroleum products are most often used low expansion foam obtained using fluorinated film-forming foam. Low expansion foam supply to the tank may be above the surface of the combustible liquid, under a layer of flammable liquid and a combined way, when the foam is applied at the same time as the surface of the burning liquid and sublayer. Subsurface method of extinguishing are useful for fighting fires oil and light oil with a viscosity during storage up to 50 mm2s-1.
      To extinguish flammable viscous liquids, and containing in its composition polar liquid subsurface method of extinguishing is not recommended.
      For more viscous oil and containing polar liquids, such as high-octane gasoline AI-95, AI-98, should apply the foam to the surface of the combustible liquid. The combined method is most appropriate to apply to floating roof tanks with fixed roofs and equipped with pontoons. The foam extinguishing media for subsurface constructed using the high-pressure foam generator, the foam on the surface can be made as a specially installed in the upper zone of the tank wall foam chambers, and with the help of mobile agents. The most effective fire extinguishing mobile fire equipment for the foam in the tank water and foam monitors can feed low expansion foam for long distances and height.
      Quite effective as penopodemniki equipped facilities combined fire of the "Blizzard", allows you to apply the foam to much larger distance than the foam medium expansion foam generators.
      Extinguishing oil and oil LOADING railroad overpasses, as well as paragraphs load petroleum products in automobile tanks, the most efficient use of water and foam monitors, as in the case of oil spills over large areas, facilities combined fire of the "Blizzard". To extinguish fires on the outer refining process units, which made mobile fire appliances, also effective to use water and foam monitors and systems combined fire of the "Blizzard".
To extinguish fires of flammable liquids and solid fuels in a confined space in recent years as more is used high expansion foam. Its use reduces the stock foam and water, stored in the protected object space and protect up to 10 m or more. In the application of high expansion foam should be aware that in case of being in the protected area of some gases, such as chlorine, ammonia, sulfur and sulfur gases, Foam drops, which makes it difficult to use it.
      Of particular interest to extinguish fires in buildings using water mist droplets with a diameter of 100-150 microns. The use of such water can eliminate the burning of almost all combustible substances and materials that are in contact with water, do not emit flammable gases and a significant amount of heat. Getting water mist may be feeding it under high pressure through special nozzles and spsobom overheating when the water heated in a confined space to temperatures well above the temperature of its boiling point at atmospheric pressure at the outlet to the atmosphere instantly boils and breaks into small droplets diameter of most less than 100 microns. When applying water mist jets burning in the hearth, a rapid decrease in temperature in the combustion zone and the flame is extinguished quickly. The advantages of this method include the rapid deposition of smoke and lowering the temperature in the protected area.
      Recently, attempts to introduce held to extinguish fires at storage, transportation and processing of oil and oil products of alternative means and methods. It is the application of liquid fire extinguishing gases, gas-aerosol and powder formulations. Note, however, that their use is very limited, but quite common in practice fighting fires is yet a lot of questions to which the answers are not often found, especially for fighting fires of flammable liquids in open spaces or leaking areas.
