Abstract

The present invention relates to a process by which a dried carboxylic acid cake is obtained from a slurry or cake carboxylic acid product through the use of at least one counter current wash. More specifically, the present invention relates to a process by which a dried terephthalic acid cake suitable as a starting material for polyester or co­polyester production is obtained from a slurry or cake terephthalic acid product through the use of at least one counter current wash.
