<p><P>PROBLEM TO BE SOLVED: To provide an ammonia treatment method by which ammonia can be reliably absorbed and recovered. <P>SOLUTION: In the method for diffusing ammonia from a pretreated material of saccharification containing ammonia which is obtained from a substrate mixture in a reaction container 2, allowing ammonia water in an ammonia absorbing tower 3 to absorb ammonia for recovery, the ammonia water in the ammonia absorbing tower 3 is diluted with water when the concentration of the ammonia water in the ammonia absorbing tower 3 reaches a value preventing absorption of ammonia. When the fluid volume of the ammonia water exceeds a reception amount limit, the ammonia water is transferred to the outside of the ammonia absorbing tower 3 and is reserved. When the diffusion of ammonia is started, the ammonia water reserved outside is flowed back to the ammonia absorbing tower 3 so that the capacity of the ammonia water to absorb ammonia may be maintained. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
