Abstract
A process is described for removing chlorides from crude oils, including heavy oils and bitumens. The process steps comprise (1) mixing a non-ionic surfactant with the crude oil, (2) bubbling a gas into the crude oil-surfactant mixture to form a froth, (3) centrifuging the frothed mixture to obtain a chloride containing sediment and an oil product of reduced chloride content and (4) collecting the oil product.
