  • Method of controlling the density of the solids separated from a feed slurry in a separator
    Patent number: 5899844
    Abstract: A method and apparatus for controlling the density of the solids separated from a feed slurry by selectively recirculating the separated liquid component of the feed slurry to change the feed slurry's density when an unwanted density of the separated solids is detected. Further, the efficiency of the separation is increased by recirculating and recharging unused catalyst into the feed slurry where it is used to assist in the separation of the solids.
