Abstract
A static devolatilisation apparatus () adapted for devolatilising a viscous liquid () comprising a volatile component is disclosed. The apparatus () comprises a phase separation chamber () in an upper region () for treating the viscous liquid () in a first devolatilisation step to form a first devolatilised viscous liquid (), and a distributor sub-unitis located below the phase separation chamber () and above a lower sump region (). The sub-unit () has a second discharge region () embodied such that it is contacted by the first devolatilised viscous liquid (), and the region () has a surface () embodied such that the first devolatilised viscous liquid () is treated in a second devolatilisation step. The present invention further relates to a process to devolatilising a viscous liquid using the apparatus () and also to the use of the apparatus () in the devolatilisation of polymer melt or solution.
