Problems with the theoretical calculations of the flash evaporation module
Thread Content
I would like to ask everyone: the flash module functions as a theoretical equilibrium stage. When multiple streams enter this module and their pressure is reduced, according to Henry’s law P=Ex, a decrease in pressure leads to a decrease in x; and based on the equilibrium equation y=Kx, y also decreases. Then shouldn’t y increase as the actual liquid-phase components flash and volatilize into the gas phase? I don’t understand. Could some expert please help explain it? Where is my misunderstanding?
Note that P is the partial pressure; think about it again
