A foaming composition for oil field, industrial and waste management applications includes a surfactant and a sulphur scavenger wherein the sulphur scavenger improves foam characteristics and/or the foam improves the activity of the sulphur scavenger. An additive may be added to the foaming composition. The additive may be a corrosion inhibitor, scale inhibitor, oxygen control agent, hydrocarbon accumulation agent and mixtures thereof which improve foam characteristics and/or where the foam improves an activity of the additive. The surfactant may be anionic, cationic, nonionic, zwitterionic and mixtures thereof. The sulphur scavenger may be an amine, a reaction product of an aldehyde or aldehyde donor and an amine or amine donor. |
