There are 5 main temperature measurement points, all of which are probe type thermocouples.
There are 5 main temperature measurement points, all of which are probe type thermocouples.
1. Inlet temperature of condenser
2. Condenser outlet temperature
3. Tower top temperature
4. Temperature at the reflux point at the top of the tower (I'm not quite sure about this area, it should be the reflux liquid due to the shallow insertion of the probe)
5. Tower kettle temperature (at the top of the reactor)
These temperatures are derived from an example of the separation of water and ethanol: not to mention the feed, it is sent to the reactor (i.e. tower kettle) and then heated. 1. The temperature basically did not change much from -1 to 2 degrees, and later it was only around 5 to 6 degrees;
2 corresponds from 1~3 degrees to 7~10 degrees later There's nothing to talk about about about this.
The temperature of 3 stabilizes at around 78-80 degrees Celsius after the temperature of the tower kettle rises.
5 is constantly rising by heating the steam to over 100 degrees. The key is 4, which rises slowly at the beginning of the heating process and remains relatively stable. Then, when it rises normally at the top of the tower, it shows some improvement and continues to rise slowly.
