This paper is concerned with separators designed for removing dispersed liquid from gas streams. The main example cited in the paper is a steam/water separator which has to be efficient and preferably compact to work in a high-pressure environment. It is shown how, in general, the separation efficiencies of such devices can be poor at high gas velocities. Reasons for this can be found in the way that liquid films and drops behave. The paper describes this behaviour and shows that understanding it can lead to better separator designs.
