| Zusammenfassung: | A method for producing methionine includes a hydrolyzing step of hydrolyzing 5-( -methylmercaptoethyl)hydantoin, and a crystallizing step of crystallizing with carbon dioxide introduced into a reaction solution after hydrolysis, to obtain methionine. In the crystallizing step, as carbon dioxide introduced into the hydrolysis reaction solution, carbon dioxide that is separated in a carbon dioxide separation section from a reformed gas formed by steam reforming reaction in a steam reformation section and carbon dioxide that is separated in an exhaust gas separation section from a combustion exhaust gas generated by pure oxygen combustion in a hydrocarbon heating furnace and a reformation reaction heating furnace are used. |
