Seeking advice on temperature changes after cooling following air resistance at the top of a distillation tower
Thread Content
I would like to ask the experts: if there is gas blockage or flow deviation in the air cooling system at the top of the distillation tower, how will the temperature after cooling by this air cooling system change? What would happen if the air resistance were severe enough to affect the flow rate of the material? I hope everyone can help clarify this; thank you in advance!
When gas blockage and flow deviation occur, the heat exchange area decreases, which inevitably leads to an increase in the temperature after cooling. At the same time, the pressure in the reflux tank and at the top of the tower also increase accordingly. When gas resistance is severe, the pressure at the top of the tower increases. The so-called air resistance is likely caused by poor heat exchange performance or blockage in one or more of the air-cooled tube bundles; if there is a blockage, the system must be shut down for cleaning. If the heat exchange efficiency is poor, check whether the fan’s airflow direction is off and if there is any air leakage. If it is wet air cooling, it is also necessary to check whether there is any deviation in the spray water flow and whether scaling has formed on the surface of the tube bundle.
