    • Disclosed is a process to produce a dry purified carboxylic acid product comprising furan-2,5-dicarboxylic acid (FDCA). The process comprises oxidizing at least one oxidizable compound selected from the following group: 5-(hydroxymethyl)furfural (5-HMF), 5-HMF esters (5-R(CO)OCH 2 -furfural where R = alkyl, cycloalkyl and aryl), 5-HMF ethers (5-R'OCH 2 -furfural, where R' = alkyl, cycloalkyl and aryl), 5-alkyl furfurals (5-R"-furfural, where R" = alkyl, cycloalkyl and aryl), mixed feed-stocks of 5-HMF and 5-HMF esters and mixed feed-stocks of 5-HMF and 5-HMF ethers and mixed feed-stocks of 5- HMF and 5-alkyl furfurals to generate a crude carboxylic acid slurry comprising FDCA, removing impurities from a crude carboxylic acid slurry in a liquid displacement zone to form a low impurity slurry stream. The low impurity slurry stream is further treated in a secondary oxidation zone to produce a secondary oxidation slurry stream which is routed to a crystallization zone to form a crystallized slurry stream. The crystallized slurry stream is cooled in a cooling zone and the resulting cooled crystallized slurry stream is routed to a solid-liquid separation zone to generate a purified wet cake stream comprising FDCA that is dried in a drying zone to generate a dry carboxylic acid product stream comprising purified FDCA (pFDCA).

    • Disclosed is a process to produce a purified vapor comprising dialkyl- furan-2,5-dicarboxylate (DAFD). Furan-2,5-dicarboxylic acid (FDCA) and an alcohol in an esterification zone to generate a crude diester stream containing dialkyl furan dicarboxylate (DAFD), unreacted alcohol, 5- (alkoxycarbonyl)furan-2-carboxylic acid (ACFC), and alkyl furan-2-carboxylate (AFC). The crude diester stream is fed to a flash evaporation zone to produce a vapor alcohol composition and a first liquid DAFD rich composition. At least a portion of the remaining alcohol can be separated from the first liquid DAFD rich composition to produce a second alcohol vapor and a second liquid DAFD rich composition, followed by separating AFC from the second liquid DAFD rich composition to product an AFC vapor and a partially purified DAFD rich composition, followed by separating a portion of the DAFD from the partially purified DAFD rich composition to produce a purified DAFD vapor.
