The Mechanism of Dewatering by Steam Filtration
J. H. Brown United States Steel Corporation, Applied Research Laboratory, Monroeville, Pennsylvania
The steam-filtration process for dewatering solids involves the application of slightly superheated steam to a filter cake during filtration. The mechanism by which the technique promotes water removal has been deduced from bench-scale experiments on coal and on granular iron ore concentrates. The mechanism, along with some of the applications and limitations of the process, is presented.
