二甲基甲酰胺抽提丁二烯工艺流程的集约化改造

Intensive transformation of dimethylformamide extraction butadiene process

二甲基甲酰胺抽提丁二烯工艺由于设备管线易聚合、易堵塞、易腐蚀,通过添加适当的管线、阀门对原有工艺流程进行了集约化改造,流程的集约化改造用较少的投入增强了装置操作的灵活性,减少了因堵塞腐蚀而造成的损失,延长了装置的运行周期,大大降低了装置因为停车带来的损失,提高了经济效益。

To resolve three problems （easily polymefized, blocked and eroded） in the dimethylformamide（DMF） extraction butadiene process, an intensive revamping for the original process was carried out just by adding some valves and pipeline, which has improved the agility of device operating, reduced the loss which resulted from blockade and erosion, prolonged the running period of device and enhanced the economic efficiency.
