Embodiment 1

[0025] The succinic acid fermentation liquid is obtained through the anaerobic fermentation of the carbohydrate by microorganisms.

[0026] Add 0.9 g of flocculant polyacrylamide to 30 L of succinic acid fermentation broth, stir at 85°C for 30 minutes, and centrifuge to obtain filtrate—magnesium succinate fermentation serum. Slowly add ammonia solution with a mass volume ratio (g / 100ml) of 17% to 35L of magnesium succinate fermentation supernatant with a concentration of 5.6% (g / 100ml), the addition amount is 2.8L, keep it for 1 hour, centrifuge Separate and wash the filter cake with a little water. The obtained magnesium hydroxide can be used for succinic acid fermentation.

[0027] The ammonium succinate solution obtained after centrifugation was 35.6L, which was pumped into the 001×7 cation exchange column at a flow rate of 1.5BV / h, and the effluent was succinic acid solution. (g / 100ml) dilute sulfuric acid solution for regeneration, and the regeneration solution ...

[0030] The succinic acid fermentation liquid is obtained through the anaerobic fermentation of the carbohydrate by microorganisms.

[0031] Add 0.9 g of flocculant polyacrylamide to 30 L of succinic acid fermentation broth, stir at 85° C. for 20 minutes, and centrifuge to obtain magnesium succinate fermentation supernatant. Slowly add 30% (g / 100ml) of ammonium carbonate aqueous solution to 35L of magnesium succinate fermented supernatant liquid with a concentration of 5.8% (g / 100ml). Wash the filter cake with a small amount of water. The resulting magnesium carbonate is used for succinic acid fermentation.

[0032] 37.1 L of ammonium succinate solution obtained after centrifugation was pumped into a 001×7 cation exchange column at a flow rate of 1.5 BV / h, and the effluent was succinic acid solution. After rinsing the separation column with a small amount of water, it is regenerated with 4% dilute sulfuric acid solution, and the regenerated solution is ammonium sulfate ...

Embodiment 3

[0035] The succinic acid fermentation liquid is obtained through the anaerobic fermentation of the carbohydrate by microorganisms.

[0036] 30 L of succinic acid fermentation broth was filtered at 70° C. using a membrane with a pore size of 0.05 μm to obtain magnesium succinate fermentation serum. Slowly add 30% ammonium bicarbonate aqueous solution into 36L concentration of magnesium succinate fermented supernatant liquid of 5.4% (g / 100ml), its addition is 7.8L, keep 1 hour, centrifuge, and wash filter with a small amount of water cake. The resulting magnesium carbonate is used for succinic acid fermentation.

[0037] 40.8L of ammonium succinate solution obtained after centrifugation was pumped into a 001×7 cation exchange column at a flow rate of 1.5BV / h, and the effluent was succinic acid solution. After rinsing the separation column with a small amount of water, it is regenerated with 4% dilute sulfuric acid solution, and the regenerated solution is ammonium sulfate ...

Abstract

The invention provides a method for extracting succinic acid from succinic acid fermentation liquor. The method includes that succinic acid fermentation liquor produced by anaerobic fermentation is filtered, filtrate directly reacts with ammonia water, ammonium carbonate or ammonium bicarbonate, the obtained filtrate is treated by resin, the obtained solution is subject to decolouration, concentration and centrifugal separation, thus obtaining succinic acid crystal. The method of the invention has the characteristics of low raw material consumption, simpler technology, short operational process, easy control and low cost.

Description

technical field [0001] The invention relates to a method for separating and extracting succinic acid, in particular to a method for extracting succinic acid from a succinic acid fermentation broth. Background technique [0002] Succinic acid, also known as succinic acid, is widely used in medicine, pesticide, fuel, fragrance, paint, food, plastic and photographic material industries. Succinic acid, as a tetracarbonic acid, is an excellent chemical platform product that can replace many commodities based on benzene and petrochemical intermediates, which can reduce the production and consumption of more than 250 phenyl chemicals pollution. At present, there are two main methods for the preparation of succinic acid: one is produced by petrochemical production, and the other is produced by microbial fermentation. The production cost of the petrochemical method is high, the pollution is serious, and it is restricted to a large extent; the production of succinic acid by the micr...
