Abstract
The present disclosure provides a system for efficiently preparing taurine, including: a solution storage unit configured to store a solution containing alkali metal taurinate, the solution being prepared by an ethylene oxide process; an ion exchange unit including at least one ion exchange resin column each configured to be activated by a first activation manner or a second activation manner independently, the first activation manner using sulfurous acid for activation to obtain alkali metal bisulfate and taurine, and the second activation manner using sulfuric acid for activation to obtain alkali metal sulfate and taurine; and a dispensing unit connected to the solution storage unit and the ion exchange unit respectively, and configured to adjust an amount of a solution conveyed from the solution storage unit to each of the at least one ion exchange resin column in the ion exchange unit.
