The present disclosure provides a process for producing taurine, includes: adjusting a PH value of a sodium taurate solution by a S4+ compound; introducing ethylene oxide into the sodium taurate solution to produce sodium hydroxyethyl sulfonate; separating crude taurine before or after introducing the ethylene oxide to the solution; and adding ammonia to the sodium hydroxyethyl sulfonate reaction solution to be reacted with the reaction solution to reproduce sodium taurate. The process for producing taurine of the present disclosure makes use of the balances of the sodium bases in the system, recycles the mother liquor until the sodium taurate is reproduced out of the reactions in the mother liquor, and thus is capable of allowing taurine to be synthesized and extracted. |
