High-stability foams for long-term suppression of hydrocarbon vapors

Novel formulations for aqueous foams which, in the presence of hydrocarbons, can persist for 24 hours or more. The foams are suitable for the suppression of hydrocarbon and polar organic vapors.

A method for supplying foam to a tank, said method comprising positioning a foam generator in a housing positioned over a tank opening, installing a foam solution line to provide foam solution to said foam generator, and supplying foam to at least a portion of said tanks. The foam generator in a housing comprises (a) a generally cylindrical body adapted to sealingly engage the tank above an opening in the tank, (b) a plate positioned to sealingly engage a first end of the cylindrical body to form a zone enclosed within the cylindrical body above the opening in the tank, and (c) a foam generator positioned in the enclosed zone for supplying foam to the tank. The method is useful for loading tanker ships.
