Abstract
A method of cleaning industrial equipment by utilizing an ebullated aqueous solution containing an amine oxide surfactant. The aqueous solution is preferably heated in a vessel, such as a batch coker fractionator in an oil refinery, to a temperature sufficient to ebullate or foam the solution and generate a substantial quantity of foam. The surfactant is carried by the foam bubbles and transported from the vessel to a contaminated surface outside of the cascading and circulating system of the vessel where the surfactant acts to remove the contamination.
