Beschreibung
Zusammenfassung:	A method and apparatus are disclosed for decontaminating a liquid surfactant of a dioxane having a vapor pressure which is higher than the surfactant. A contaminated liquid surfactant is directed through an inclined conduit. A gas is directed into the inclined conduit, whereby the gas contacts the surfactant and transports the dioxane contaminant, which has volatilized in the inclined conduit, out of the inclined conduit, thereby decontaminating the surfactant. The liquid surfactant is discharged from the inclined conduit.
