讨论尿基过磷酸钙生产过程中反应剂制备的热力学原理和物化参数 ,讨论混合反应中工艺参数确定的基本原则。所提出的流程不但可以生产二元氮磷复合肥 ,也可生产不同比例的氮磷钾三元复合肥。
The thermodynamic principles and physico-chemical parameters of reagent preparation in the process of urine-based superphosphate production are discussed. The basic principles for determining the process parameters in the mixed reaction are discussed. The proposed process can not only produce binary nitrogen and phosphorus fertilizer, but also produce different proportions of NPK ternary compound fertilizer.
