尿基过磷酸钙复合肥新工艺研究
Study on new technology for manufacture of ureabased SSP compound fertilizer
【摘要】 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。
【Abstract】 The new process of ureabased SSP is presented. Meanwhile the thermodynamics characteristics of preparing digestion solution and basic parameters in mixture reaction are discussed. Not only NP compound fertilizer, but also multinutrients compound fertilizer can be produced by the process.
