| titleOfInvention | Process for producing carboxylic acid |
| abstract | The invention relates to a method comprising the following steps: subjecting a carbon source to a fermentation step to form a carboxylic acid, the step of neutralizing at least a portion of the carboxylic acid obtaining magnesium carboxylate; subjecting magnesium carboxylate to an acidification step to form an aqueous mixture comprising carboxylic acid and magnesium chloride; subjecting an aqueous mixture comprising carboxylic acid and magnesium chloride to a separation step to form an effluent comprising a solution of carboxylic acid and magnesium chloride; supplying an aqueous solution comprising from 5 to 25% by weight of MgCl2 and optionally organic contaminants to an evaporation step to evaporate water and organic components present therein; an aqueous solution having a concentration of MgCl2 in the range of 25 to 35 wt% is taken from the evaporation step and supplied to a preconcentrator where it is contacted with a gaseous stream comprising HCl at a temperature of at least 300 ℃; supplying an aqueous solution having a concentration of MgCl2 of 35-45 wt% obtained in the pre-concentration step to a thermal hydrolysis reactor, the temperature of the reactor being at least 300 ℃; withdrawing MgO in solid form from the thermal hydrolysis reactor, and withdrawing an HCl-containing gas stream from the thermal hydrolysis reactor, the HCl-containing gas stream having a temperature of at least 300 ℃; providing a HCl-containing gas stream having a temperature of at least 300 ℃ to a preconcentrator; an HCl-containing gas stream is withdrawn from the preconcentrator at a temperature of up to 150 ℃. |
