Abstract: 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 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).

Abstract: A process to produce a purified dimethyl-furan-2,5-dicarboxylate (DMFD) by feeding furan dicarboxylic acid and methanol to an esterification zone to generate a crude diester composition, and purifying the crude diester composition with a physical separation process followed by crystallization, solid liquid separation, and optionally drying to produce a purified DMFD composition. A portion of the stream generated by solid liquid separation can be dissolved and subjected to crystallization and solid liquid separation repeatedly. The process is useful to produce a purified DMFD composition having a low b*, at least 98 wt. % DAFD solids, and a low concentration of 5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) and methyl 5-formylfuran-2-carboxylate (MFFC).

Abstract: 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.

Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.
