A method and apparatus for separating the components of a feed material prio r to or simultaneously with at least partially vaporising one of the component s is described. The apparatus comprises at least one inlet (8) for admitting t he feed material (10) containing the two components to the apparatus (2) wherei n a device for introducing a first movement to the feed material is located, such as, for example, an in-line swirl generator (14), which imparts a swirling movement to the feed material to partially separate the components into two swirling flows. The partially separated material on emerging from t he in-line swirl generator (14) is in an evaporation tube (20) in which the mor e volatile component is vaporised to further assist in separating the two components into a liquid component and a gaseous or vapour component. The liquid component and the vapour phase are discharged from the apparatus in t wo streams through the same outlet (36). Modifications of the method and apparatus include (i) having multiple evaporation tubes (20), each optionall y provided with its own in-line swirl generator to facilitate better distribution and separation of the feed material, and (ii) having a reject nozzle (40) and reject conduit (42) located within the generator for allowin g passage of vapour or gasthrough the in-line swirl generator (14) when there is an intermediate flow formed in the generator (14) and conveyed to the evaporation tube (20). The method and apparatus of this application are used as a pre-treatment in an overall separation plant.
