ABSTRACT:
A slurry of particulate material, such as polypropylene, and a fluid, such as propylene diluent, is introduced into a flash tank to remove a substantial amount of the fluid. The resulting particulate material is passed from the flash tank through a heated dryer to elevate the temperature of the particulate material and remove additional fluid. The temperature of the particulate material removed from the dryer is controlled by measuring the temperature of the removed material and adjusting the rate at which vapor is removed from the dryer in response to the measured temperature.
