Abstract
A process for recovering by-products of a substituted aromatic hydrocarbon oxidation reaction, comprising cooling one or more of a vapor stream directed to a high-pressure absorber (), a solvent-rich scrubbing stream () directed to a high-pressure absorber (), and a water-rich liquid stream () directed to a solvent recovery zone, by heat exchange with a cooled spent scrubbing liquid withdrawn from a low-pressure scrubber ().
