  • Patent number: 11752447
    Abstract: The present disclosure is a method of removing contaminants from a feed stream comprising said contaminants and process liquid by bringing the feed stream into contact with a heated heating fluid in or in proximity to a separation vessel thereby causing process liquid to vaporise and flow out of the separation vessel as vapour, after which it can be recovered. Embodiments of the method may include using a heavy heating fluid whose density is higher than that of the feed stream and/or vigorously agitating the pool of heating fluid in the separation vessel.

  • Publication number: 20160271531
    Abstract: 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.
