Document Type and Number:
Japanese Patent JP7041728
Kind Code:
B2
Abstract:
The invention discloses a method and a production system for fully recovering and treating taurine mother liquor, which is used for the process of ethylene oxide taurine production process. As for the treatment of the last mother liquor of taurine, add alkali firstly to the last mother liquor of taurine and then acid to form salt, or add salt directly; then concentrate and crystallize and filter, to remove lots of impurities in taurine mother liquor, and solve the problem of separating impurities, greatly shorten the time of removing impurities, decolorize and remove impurities further by activated carbon, and remove by salt mixing ammonia into the mother liquor to obtain the pure taurine mother liquor, thereby recovering the mother liquor and increasing the product yield.
