Method for removing liquid from a liquid-solids mixture

摘要

An apparatus and method are provided wherein liquid is removed from a liquid-solids mixture by employing both filtration and low pressures to achieve vaporization of liquid. The mixture is introduced to a vessel in which the mixture is filtered so that a substantial portion of the liquid is withdrawn from the vessel. The vessel is then depressurized to an extent necessary to vaporize a substantial portion of the remaining liquid. Such vapor is withdrawn from the vessel. During vaporization, the contents of the vessel are agitated and heated.
