Reduce the relative humidity of the outlet gas from the spray tower
Thread Content
Hello, seniors! I am simulating a water washing tower, using an aqueous solution containing NAOH to wash the waste gas containing phenol and SO2, 30° water, the feed rate is 70cum/h, 90° waste gas, the feed rate is 30000Nm3/h. The current situation is that the relative humidity at the outlet reaches 99%+, which is very different from the actual relative humidity. So I would like to ask you seniors what kind of settings can be made to reduce the relative humidity of the outlet gas of the spray tower.
You didn't consider the effect of electrolytes. If you don't keep it warm, it might be oversaturated.
Hello, senior! I chose the electrolyte model and the physical property method: ELECNRTL. The relative humidity of the gas at the outlet reaches 99%. When I increase the relative humidity of the gas at the inlet, I can reduce the difference in relative humidity between the inlet and outlet gas, so that the temperature will be more reasonable. However, in the actual process, the relative humidity at the inlet cannot be changed casually. I really haven't considered the issue of thermal insulation you mentioned. Can seniors explain in more detail how to achieve thermal insulation?
