PROCESSING METHOD FOR SEPARATING AMMONIA INCLUDED IN WASTE, METHOD FOR RECYCLING AMMONIA, METHOD FOR PRODUCING CEMENT RAW MATERIAL, AND SYSTEM FOR MANUFACTURING CEMENT

To provide a processing method that effectively and efficiently can separate ammonia from ammonia-containing exhaust gas.SOLUTION: A processing method for separating ammonia included in waste comprises: an ammonia condensing step in which ammonia-containing exhaust gas is supplied to an absorption tower and the ammonia contained in the exhaust gas is condensed together with service water for absorption; a pH adjusting step in which pH of ammonia liquid including the ammonia condensed in the ammonia condensing step is adjusted to pH of alkali; an ammonia separating step in which ammonia included in the ammonia liquid is gasified and separated from the ammonia liquid having pH adjusted in the pH adjusting step; and a service water circulating step in which drainage water remaining after separating the ammonia in the ammonia separating step is neutralized and cyclically used as service water for absorption in the absorption tower.SELECTED DRAWING: None 【課題】アンモニア含有排ガスから有効に且つ効率的にアンモニアを分離することができる処理方法を提供する。【解決手段】アンモニア含有排ガスを吸収塔に供給し、前記排ガスに含まれる該アンモニアを吸収用水と共に凝縮するアンモニア凝縮工程と、前記アンモニア凝縮工程で凝縮された該アンモニアを含むアンモニア液のｐＨをアルカリに調整するｐＨ調整工程と、前記ｐＨ調整工程でｐＨ調整された該アンモニア液から、そのアンモニア液に含まれるアンモニアを気化して分離するアンモニア分離工程と、前記アンモニア分離工程で前記アンモニアを分離したあとに残る排水を、中和して、前記吸収塔における吸収用水として循環利用する用水循環工程と、を備える処理方法である。【選択図】なし
