絮凝

使用颗粒分布控制研发絮凝工艺

絮凝是生化技术、石油、纸浆与造纸和采矿行业常用的一种分离法。絮凝是这样一个过程:细悬浮颗粒聚合形成较大絮状物并从液相沉淀,从而降低溶液的浊度。絮凝聚合物和化学物的性能取决于流入颗粒粒径分布、颗粒浓度、混合效率以及添加剂类型和剂量。絮凝效率会对下游分离、沉淀、浮选与提纯产生影响。

通过应用基于聚焦光束反射测量 (FBRM) 的Particle Track和颗粒录影显微镜 (PVM)的探头式的颗粒测量技术,可以在对整个工艺浓度范围进行在线测量的同时跟踪絮状物分布的实时变化 – 而无需取样。ParticleTrack 和  PVM 过程分析技术 (PAT) 可以使得实验室内的絮凝性能得以快速优化,同时还能控制工厂内的固态絮凝和下游分离 – 即使流入的颗粒系统发生变化亦是如此。

絮凝应用包括:

  • 优化生物细胞和细胞碎片分离
  • 提高纸浆与纸张产量,留存和产品质量
  • 油/沙尾矿沉淀速率
  • 采矿业废水沉淀速率
  • 絮凝剂和化学表面活性剂的效率


自从 2001 年购买 Lasentec 后,梅特勒-托利多已经成为在线分析颗粒/液滴粒径、形状和数量特性的全球领导者。
