    Abstract: A method and a production system for 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. This solves the problem of separating impurities, greatly shortening the time of removing impurities. The last mother liquor can also be decolorizes and additional impurities removes by activated carbon, and the removal of salt by mixing ammonia into the mother liquor to obtain the pure taurine mother liquor, thereby recovering the mother liquor and increasing the product yield.
