ABSTRACT:
A degassing apparatus for use with a polymerisation reactor is disclosed. Slurry from the reactor is discharged into a flask tank (3) in which monomers or dilluent vaporise to form a gas. Filler units (9, 10) are provided at the upper part of the flash tank (3). They may be selectively connected to the flash tank by valves (11, 12). No cyclone etc. is provided between the flash tank and the filter (9, 10) and these particles may then fall back into the flash tank (3). The filters may be separately isolated for cleaning or replacement.
