| titleOfInvention | Process for puriying an organic acid |
| abstract | A process is disclosed for purifying an aqueous feed stream (10) comtaining a product organic acid and a strong contaminant such as another organic acid. The molar concentration of the organic acid in the feed stream (10) is at least 20 times greater than that of the contaminant. The feed stream (10) is contacted with an immiscible basic extractant (18) that has a greater affinity for the contaminant and which complexes with the contaminant and some of the organic acid. The complexed extractant is separated from the aqueous stream (10), so as to produce a first effluent stream (20) comprising product organic acid. The complexed extractant is contacted with a displacing acid, for which the extractant has a greater affinity than contaminant or extractant. As a result, a second effluent stream (28) comprising organic acid and a third effluent stream (30) are produced. |
