Pressure distillation?
Thread Content
I have been conducting experiments on pressure-driven distillation recently, and I have two questions for those with expertise. Thank you all! 1. What is the sequence of steps for starting up pressure-driven distillation? 2. If an inert gas is used to increase the pressure, what considerations should be taken into account?
The process for starting up any distillation unit is basically the same: first, feed is added to the bottom of the tower, and this can be seen through the level gauge； Heating at the tower bottom, cooling at the tower top ； At the top of the tower, there is reflux, and non-condensable gases are discharged when the pressure starts to rise. It is incorrect to claim that pressure increases \"by using inert gases\"; generally, there is a linear relationship between the pressure of a substance and its saturation temperature, just as in the case of steam, where an increase in pressure leads to an increase in the condensation temperature as well. So, rising pressure is addressed by increasing the temperature!
