Zusammenfassung:The present invention relates to method and apparatus for ammoniating potassium bisulfate solution to produce sulfur-base composite fertilizer. For low cost, the ammoniating step has ammonia or carbonized ammonia of 5-35 concentration used while liquid ammonia or gaseous ammonia may be replenished for ammoniating potassium bisulfate solution. Compared with available technology, the present invention solves the side product ammonia water to low the production cost in producing several kinds of composite fertilizer.
