Abstract

The present disclosure provides a method for continuously and efficiently preparing taurine, including: (a) bringing an ethylene oxide with an alkali metal bisulfite into an addition reaction to obtain an alkali metal isethionate; (b) bringing the alkali metal isethionate with an ammonia into an ammonolysis reaction to obtain a solution containing alkali metal taurinate; and (c) inputting the solution containing alkali metal taurinate into at least one acid cation exchange resin column in activated state to obtain the taurine through an acidification treatment, followed by activating a portion of the at least one acid cation exchange resin column by a first activation manner using sulfurous acid and obtaining a solution containing alkali metal bisulfite, and activating another portion of the at least one acid cation exchange resin column by a second activation manner using sulfuric acid, wherein the first and second activation manner may be performed on a same acid cation exchange resin column alternatingly or on different acid cation exchange resin columns.
