A SOLVENT DRYING COMPOSITION AND PROCESSES THERFOR

The present disclosure relates to a solvent drying composition and processes therefor. The present disclosure more specifically relates to a solvent drying composition that in use releases water from a solvent mixture. The present disclosure also relates to a process for recovering a solvent drying composition, more specifically to a process for recovering a solvent drying composition used in an osmotic process.

PROCESSES FOR PRODUCING NH4+ -OOC-R-COOH COMPOUNDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COO-NH4+COMPOUNDS AND/OR HOOC-R-COOH COMPOUND ACIDS, AND CONVERSION OF NH4+ -OOC-R-COOH COMPOUNDS TO HOOC-R-COOH COMPOUND ACIDS

A process for making a NH4+ OOC-R-COOH compound from a clarified NH4+ OOC- R-COO' NH4+ compound-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes a NH4+ OOC~R~COOH compound, at least some of a NH4+ QOC-R-COO" NH4+ compound, and at least about 20 wt% water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a NH4+ OOC-R~C00' NH4+ compound-containing liquid portion in contact with a NH4+ OOC-R-COOH compoond-containing solid portion that is substantially free of the NH4+ OOC-R-COO" NH4+compound; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.

PROCESSES FOR PRODUCING HOOC-R-COOH COMPOUND ACIDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COQ-NH4+ COMPOUNDS

A process for making HOOC-R-COOH compound acid from a clarified NH4+ -OOC- R-COO-NH4+ compound-containing fermentation broth including distilling the broth under super atmospheric pressure at a temperature of >I00°C to about 250°C to form an overhead that comprises water and ammonia, and a liquid bottoms that Includes HOOC-R-COOH compound acid, and at least about 20 wt%. water; cooling the. bottoms to a temperature sufficient to cause the bottoms to separate into a liquid portion in contact with a solid portion that is substantially pure HOOC-R-COOH compound acid; separating the solid portion from the liquid portion; and recovering the solid portion.
