text: Removal of the excess hydrocarbon may be carried out continuously or periodically or, as an alternative, it may be possible, depending on the identity of the hydrocarbons which are being used as the extractant and of those which are being removed from the water, to maintain the gross composition of the hydrocarbons in the recycle loop at a relatively constant value by separation of the extractant, for example by distillation by flash separator or a limited number of stages in a distillation tower.
