What are the reasons for high pressure at the top of a distillation tower?
Thread Content
Why is the pressure at the top of the distillation tower in the workshop high, reaching 15 KPa, and why does the temperature at the top of the tower drop as soon as the feed volume increases?
By \"adding material to the top of the tower,\" you probably mean increasing the reflux ratio, right? It’s normal for the tower top temperature to drop when the reflux volume increases. 1. First, please verify the normal operating range of your distillation tower, including the feed rate and reflux ratio. 2. If everything is normal, check the condition of the condenser at the tower top; a decrease in heat transfer efficiency can also lead to high pressure at the tower top. 3. It’s also possible that there is severe leakage from the tower trays, which can be detected by examining the quality of your product. This is just based on operational experience, so it might not be accurate :)
The distillation tower is not a rectifying tower; there is no reflux, only feed
I originally thought it was distillation... If the temperature at the bottom of the tower is normal, is the yield appropriate?
