Optimized production of aromatic dicarboxylic acids

摘要: Disclosed is an optimized process and apparatus for more efficiently producing aromatic dicarboxylic acids (e.g., terephthalic acid). In one embodiment the process/apparatus reduces costs by recovering purifying residual acid present in liquid phase of initial oxidation slurry. another associated with hydrogenation forming a final composite product containing unhydrogenated particles.
