Abstract

A method of cleaning water to remove hydrocarbon, comprises: (i) adding an external diluent to the water; and (ii) removing the hydrocarbon together with the diluents from the water. The method may be used to clean water of a hydrocarbon/water mixture extracting using steam in a subterranean formation, such as an oil well. The external diluent may be added to the water prior to cooling, and may be a mixture of C30-60 hydrocarbons with a boiling point in the range of 30-130ºC. Examples of the diluents include naphtha, light crude oil or gas oils, synthetic oil, gas condensates, or mixtures of these. A system for cleaning water by removing hydrocarbon comprises: (a) a means for adding an external diluent 102 to water separated in a bulk separator 105; and (b) a means for removing hydrocarbon together with the diluents from the water, and comprising an outlet for water. The means for adding an external diluent comprises at least one inlet for the external diluent in between the bulk separator and the means for removing hydrocarbon from the water.
