摘要
介绍了配套固相增黏装置的前期PET装置中切粒系统传统工艺流程,指出其运行期间存在的问题,提出了用BKG结晶切代替传统切粒机的改造方案,对改造前后的节能效益进行了比较。
The traditional technological process of pelletizing system in first-phase PET plant which match to the solid state polycondensation was introduced. The existing problems during its operation were pointed out. The transformation scheme that using BKG crystall cut instead of traditional granulator was proposed. The energy efficiency preand post-transformation was compared.
