Looking for phase equilibrium calculation software or methods
Thread Content
Dear sea friends, when calculating the water-washed methanol absorption tower, I need to determine or calculate the phase equilibrium constants, and I’m not sure how to do that; that’s why I’m seeking help from everyone. I have a value for the Henry coefficient, but I don’t have information regarding the methanol component
Phase equilibrium constant = partial pressure/saturated vapor pressure
Theoretically, methanol is infinitely soluble in water. Is your washed methanol obtained by washing methanol out of a methanol-rich gas phase? Can it be considered that the Henry’s law constant E is very small? It can basically be washed off.
Thank you for your reply, Secretary. The gas comes from the methanol storage tank; it has a concentration of 0.2%. With a flow rate of 120 mol/h, a tower diameter of DN800 is required, and what should be the height of the packing? What went wrong?
