How much water can nitrogen carry away?
Thread Content
There is such a question: The material contains 150–200 ppm of water. By using a dehydration tower filled with nitrogen at a dew point of -45°C and with a purity of >99.9% (under which condition the water content is around 60–71 ppm), is it possible to reduce the water content in the material to 40–60 ppm? Please discuss this.
Using nitrogen to carry away water relies on the principle of reducing water vapor pressure, and it is necessary to calculate how much can be carried away.
