ABSTRACT:
The static devolatilisation apparatus serves to treat a liquid (7) containing polymers for the purpose of polymer devolatilisation. Volatile components are separated from the polymers in that the liquid standing under pressure is expanded in at least one phase separation chamber (2) in the upper regions of the container (10). A discharge pump (3) for the devolatilised polymer is located at the base of a sump region. An extraction line (4) for gases (8) is located in the upper region. The separation chamber includes an inlet (20) for the liquid to be treated, lower openings (210) for polymer discharge and at least a single upper opening (220) for gas discharge.
