Rehydrator level alarm
Thread Content
The heat well level in the rewatering system is equipped with high alarm, high-high alarm, low alarm, and low-low alarm. What are the actions taken by the rewatering system for each of these alarm levels? I heard from a colleague that setting a high value is used for the automatic start-up of the standby pump; is that correct?
High reporting indicates the normal situation of the standby pump starting automatically
It should be designed in this way to ensure safety, but the upper limit should not be set too high; some time must be reserved for emergency handling by the backup pump, in case the backup pump fails to start when needed.
You must be from an olefin separation unit; it would be better to ask an engineer this question, haha
