Title:
How to process chlorination magnesium fluid
Document Type and Number:
Japanese Patent JP6255093
Kind Code:
B2
Abstract:
The invention pertains to a method for manufacturing a carboxylic acid comprising, int. al., the steps of
- subjecting a carbon source to a fermentation step to form a carboxylic acid and neutralizing at least part of the carboxylic acid by adding a magnesium base, thereby obtaining a magnesium carboxylate,
- subjecting the magnesium carboxylate to an acidification step using HCl, to form an aqueous mixture comprising carboxylic acid and magnesium chloride,
- subjecting the aqueous mixture comprising carboxylic acid and magnesium chloride to a separation step,
- providing an aqueous solution comprising 5-25 wt.% of MgC12 and optionally organic contaminants to an evaporation step,
- withdrawing an aqueous solution with a MgC12 concentration of 25-35 wt.% from an evaporation step and providing it to a preconcentrator where it is contacted with a HCl containing gas stream with a temperature of at least 300°C,
- providing an aqueous solution resulting from the preconcentrator to a thermohydrolysis reactor, at a temperature of at least 300°C,
- withdrawing MgO from the thermohydrolysis reactor, and withdrawing a HCl containing gas stream from the thermohydrolysis reactor,
- providing the HCl-containing gas stream with a temperature of at least 300°C to the preconcentrator,
- withdrawing a HCl-containing gas stream with a temperature of at most 150°C from the preconcentrator. It has been found that the process according to the invention can be integrated into a fermentation process in such a manner that a stable and efficient process is obtained.
