Abstract:
It is an object of the invention to provide a process for producing an organic acid, comprising: providing an incoming stream containing an organic acid and impurities; subjecting said incoming stream to a step of chromatographic separation, using a solution of mineral acid as an eluent, so as to collect an extract and a raffinate, the organic acid being recovered in the extract; and subjecting the raffinate to an electrodialysis step, so as to collect a diluate and a concentrate, the mineral acid being concentrated in the concentrate. The invention also provides an installation for implementing this process.
