Emptying principle
Thread Content
No one has systematically summarized the precautions for emptying it,,, Please share your thoughts. . Let me start with a preliminary suggestion: 1. Pour the liquid first, then the gas. In other words, after stopping, use the inherent pressure to push the liquid material into the collection tank or waste line; when the pressure is insufficient, then add nitrogen for purging. After the liquid phase is emptied, the gas phase is vented to a flare. . 2. First release high pressure, then low pressure, to prevent cross-contamination of materials. . I’m not sure if what I’m saying is correct; everyone, please speak up actively – I’ll give out high scores for that. (There are only 50 left.)
The original poster has covered everything comprehensively, but if liquid ammonia is used as the medium, a pump should be used to empty it.
