新技术在100kt/a苯胺流化床反应器上的应用

Application of the new technologies on 100 kt/a aniline fluidized bed

采用清华大学多项专利专有技术,结合南化公司苯胺生产10多年经验,对苯胺行业传统的鼓泡床进行技术创新。新建成的利用国内技术最大直径的100 kt/a苯胺流化床,不仅实现了鼓泡床向湍动流化床的转变,而且具有产品质量满足MDI企业要求、断面负荷高、操作弹性大、催化剂寿命长等诸多优点。

The technical innovation on traditional bubbling bed in aniline production is carried out applying several patent and special technologies of Qinghua University and combining experience of aniline production over 10 years. The 100 kt/a aniline fluidized bed wiht biggest diameter is set up using domestic technology, which not only achieves the change from bubbling bed to turbulent fluidized bed but also has some advantages, such as satisfied the demands of MDI enterprises, high section load, wide operating range and longer lifetime of catalyst.
