摘要:
Disclosed are methods and apparatus for use in producing a low-moisture carboxylic acid wet cake. Such a low-moisture wet cake can comprise less than about 12 weight percent liquid and can be achieved by washing a carboxylic acid wet cake in a product isolation zone with a wash stream having an initial temperature of at least about 40° C.
