How to deal with boiling in high-temperature dehydrated coal tar
Thread Content
The water content is around 20%. When the sample is heated to 105°C and it starts to boil, what should be done? It’s a 60-ton horizontal tank filled with heat transfer oil that needs to be heated
The aqueous solution can be achieved in about five steps at the end
If the temperature rises too much, it can easily cause the water to vaporize and boil; in open equipment at atmospheric pressure, this will lead to boiling. My suggestion is to use the difference in density for dehydration – this should make it easy to achieve a moisture content of less than 5%. If the densities are similar, apply appropriate heating, but avoid reaching the boiling point
No free water can be generated here; it can only evaporate
It can only evaporate water; it cannot produce liquid water
Try controlling the dehydration temperature at 97 degrees Celsius

The main issue is that visible water cannot be seen; one can only use gas to stir things around and cause evaporation. The resulting visible water is difficult to handle
I want to be extra cautious: start at around 85 degrees and heat for 10 hours to measure the moisture level. If the moisture is low, increase the temperature to around 150 degrees; if there’s already a lot of moisture, use a temperature above 90 degrees
Since it’s natural gas, the costs are relatively high; we’re now thinking about ways to reduce expenses
