摘　　要：介绍采用“中和料浆浓缩法工艺”的粉状 MAP装置与采用传统“磷酸浓缩工艺”的大型进口粒状 DAP装置实现“联产”,促进、优化后者的生产和经营的科技创意与实践效果 ,以及联产装置内采用的部分创新技术 ,如强制循环氨中和蒸发反应器、中和蒸汽二次利用节能技术。The cooperation of 2 plants, one is for powdered MAP by 'neutralized slurry concentration process' and another is for granular DAP by conventional 'phosphoric acid concentration process', is described , thus enhanced the DAP production and marketing capacity. Also some innovations for the cooperation are presented, such as the forced cycling ammonia neutralization evaporator, neutralization steam re utilization technology for energy saving.
