PROCESS AND APPARATUS FOR RECOVERING VALUABLE OR HARMFUL NON-AQUEOUS LIQUIDS FROM SLURRIES.

摘要

This invention relates generally to a process and an apparatus therefor for recovering valuable or harmful non-aqueous process liquids from mixtures or slurries that contain such liquids and solid particles. In a first aspect there is provided a filtration process for recovering a substantially non-aqueous process liquid from a feed slurry that predominantly comprises a mixture of the process liquid and solid particles, the process employing a sweep liquid that is less dense than the process liquid.
