Subtract two for temperature change
Thread Content
The temperature at the second-stage reduction point has suddenly changed by several dozen degrees, while the temperatures at the other points remain unchanged. What could be the reason for this?
Does the sub-second-line temperature refer to the device temperature or the exhaust port temperature? If it is the temperature of the device, it is necessary to check whether there are leaks in the heat exchanger and whether there are significant changes in the temperature of the circulating water, etc. To determine the temperature at the extraction port, it is necessary to consider whether there are any other parameters that have changed, and to conduct a comprehensive analysis in order to identify the cause of the problem.
If it’s a problem with the circulating water, other side lines should also have issues. . . Are you referring to the drawing temperature for line 2 minus?
Reply to 2# Under the Windy and Rainy Platanus – Thank you! I forgot to mention it – it’s the distillation temperature
The feed from the second stage is unstable; it alternates between gas phase and liquid phase, which causes fluctuations in the distillation temperature.
How often do the fluctuations occur, and what is the temperature range? How much does the extracted flow rate change? Does the temperature of the output device change accordingly when reducing to the second level? Were the temperatures at No. 2 Middle School, the front line, and No. 1 Middle School not affected at all? Is it a packing or a tray? It could be due to internal component failures in the tower, coking of the packing, blockages in the tray, or poor flow at the outlet of the liquid collection tank.
