The Analysis of Oil Suppression by Aqueous Film Forming Foam through a Gas-Salt Layer of Water

Abstract:

Regularities and procedure of suppression of oil flame through a gas-salt layer of water are determined as a result of laboratory experiments. Conclusion about defining role of surface activity of foam concentrates in guaranteeing of reliable flame suppression by foam in process of its supplying into the bottom of tank through a gas-salt layer of water is drawn. Time of oil product suppression, which includes the time of saturation of a gas-salt layer of water by surface-active substances and the time of burning elimination, is defined. It is revealed that foam rising through a gas-salt layer of water in an initial time point loses the part of active substances (mainly hydrocarbon component) and partially destructs. Influence of hardness salts on a superficial tension of foam concentrates solutions is shown.
