Kind Code:
A1
Abstract:
The present invention provides a system for efficiently preparing taurine. The system comprises: a liquid storage unit, configured to store a solution containing an alkali metal salt of taurine prepared by an ethylene oxide method; an ion exchange unit, comprising a plurality of ion exchange resin columns, a single ion exchange column being independently activated in a first activation mode or a second activation mode, wherein the first activation mode activates by using sulfurous acid, to obtain an acid sulfurous alkali metal salt and taurine, and the second activation mode activates by using sulfuric acid, to obtain alkali metal sulfate and taurine; and a distribution unit, separately connected to the liquid storage unit and the ion exchange unit and configured to adjust an amount of the transport solution of the plurality of ion exchange resin columns in the ion exchange unit by the liquid storage unit.
