Abstract
In a process for the separation of solid carboxylic acid fines from mother liquor that includes such fines, the mother liquor is fed to a settlement drum at above atmospheric pressure. The mother liquor having a lower concentration of carboxylic fines than that fed to the settlement drum is then removed, wherein the mother liquor removal occurs at a point above the point at which the mother liquor containing fines is fed to the settlement drum. In a system for performing the separation process, a settlement drum has an inlet for mother liquor with carboxylic acid fines and an outlet for mother liquor having a lower concentration of carboxylic acid fines content than that of the mother liquor introduced via the inlet. The settlement drum is configured to operate at above atmospheric pressure and the outlet is located at a point in the settlement drum above the inlet.
