  • Solid-Liquid Separation Processes Using a Large Pore Filter
    Publication number: 20210246096
    Abstract: Solid/liquid separation processes using a large pore filter. One aspect of the disclosure is a process comprising filtering a solid/liquid mixture of a collection of solid aromatic carboxylic acid particles in a solvent in a first zone of a rotary pressure filter apparatus to form a filter cake on a filter surface, and removing the filter cake from the filter surface.

  • Solid-liquid separation with a no-dry rotary pressure filter
    Patent number: 9486722
    Abstract: A process for recovering a solid product from a solid/liquid mixture. The process includes filtering a solid/liquid mixture to form a filter cake in a first solid-liquid separation zone. The filter cake comprises the solid product. The first solid-liquid separation zone comprises a rotary pressure filter apparatus configured to apply a pressure differential across at least one filter member, and the filter cake is formed on the filter member. The filter cake is then washed with fluid in the rotary filter apparatus to form a wet filter cake. The wet filter cake is then transferred to a reslurrying zone. The wet filter is mixed with a reslurrying fluid to form a slurry, and the slurry is transferred to a second solid/liquid separation zone, where the solid product is separated from the slurry.
