1. one kind is used for slurry olefin polymerization and with thinner and the isolating method of polymer solids, this method comprises:

  • In reaction zone, make the polymerization in liquid diluent of at least a olefinic monomer, thereby produce the fluid slurry that comprises liquid diluent and polymer solids;

    Discharge a part of slurry from reaction zone;

    The part slurry that heating is discharged;

    The slurry of discharge section is delivered to middle nip, and wherein most of thinner separates with polymer solids, and wherein the pressure range of middle nip is 100-1500psia;

    Therefrom nip is discharged polymer solids;

    WithPolymer solids is not transported to cleaning area by flash zone.
