PTA残渣粉料的氧化回用

Recovery PTA powdery residue by oxidization

通过将E-PTA残渣粉料返回氧化反应器,深度氧化回收TA,减少残渣量,降低PX单耗。以绍兴远东石化技改为实例,提供一种残渣利用的新思路。

The E-PTA powdery residue was returned to oxidation reactor,the TA was recovered by deep oxidation. The amount of residue was reduced,the PX unit consumption was decreased. Taking the technical transformation in Shaoxing Yuandong Petrochemical for example,a new idea for reuse the residue was provided.
