Abstract:
1. An apparatus for separating diluent from polymer solids, the apparatus comprising: an intermediate pressure chamber adapted to separate diluent vapor from polymer solids, the chamber having an inlet adapted to receive a fluid slurry comprising diluent and polymer solids from a slurry reactor, a solids outlet adapted to discharge the polymer solids, and a gas outlet adapted to discharge the diluent vapor; a level sensor adapted to sense a level of polymer solids in the intermediate pressure chamber; an outlet valve fluidly connected to the solids outlet of the intermediate pressure chamber, wherein the outlet valve is adapted to be manipulated in response to the sensed level; a condenser fluidly connected to the gas outlet, the condenser adapted to receive and condense without compression the diluent vapor; and a purge column fluidly connected to the outlet valve, the purge column adapted to receive the polymer solids from the intermediate pressure chamber.
