PROCESS AND ROTARY PRESSURE FILTRATION APPARATUS FOR SLURRY SEPARATION OF AROMATIC CARBOXYLIC ACIDS

摘要

In a process for removing aromatic carboxylic acid from a slurry thereof in solvent, the slurry is split into sub streams and each of said sub streams is supplied to a respective rotary pressure filter such that the sub stream pass through the filters in parallel. Gas is passed through the rotary pressure filters in series in an open-loop arrangement.
