| 摘 要： | 分析了环己酮肟生产中氨肟化装置膜分离系统运行不稳定的原因;提出了技术改造和工艺优化措施。结果表明:膜分离系统膜管表面污染导致其运行不稳定,原因是生产中弱碱性条件下破碎的催化剂颗粒附着在膜表面形成沉积层。通过提高错流速率,稳定反冲压力,改变反冲方式和反冲介质等优化措施,可实现膜分离系统的稳定运行。 |

| Abstract: | The reasons for the operation instability of membrane separation system were analyzed for ammoximation unit of cyclohexanone plant.The technological transformation and process optimization were described.The results showed that the membrane tube surface contamination of the membrane separation system caused the operation instability,which resulted from the deposition layer of broken catalyst particles on the membrane tube surface in alkalescent environment.The stable operation of membrane separation system ... |
