Embodiment 1
[0026] Utilize 60 order filter screens to carry out pretreatment to 100kg glutamic acid centrifugal mother liquor, to remove large particle impurity, obtain glutamic acid mother liquor prefilter.
[0027] The temperature of the pre-filtrate obtained in step (1) was raised to 50° C., and the pre-filtrate was pressurized by a booster pump and then passed through an alumina ceramic membrane with a pore size of 50 nm for microfiltration. The operating pressure of the microfiltration is 0.2MPa, and the membrane surface velocity of the microfiltration is 3m / s. Obtain ceramic membrane filtrate.
[0028] Use 0.5m 3 The 723 cation exchange resin adsorbs glutamic acid in the above ceramic membrane filtrate, the adsorption rate is set to 1 BV / h, and then eluted with 50% ammonia solution. The elution rate of ammonia solution is 0.5 BV / h, and the resin life in this process is 2 years.
[0029] Send the above eluate to the evaporator to evaporate and concentrate to a concentrated solutio...
