Henry's law
Thread Content
“For ideal solutions, under conditions of low pressure and constant temperature, Henry’s law holds true across the entire range of compositions, with the Henry constant being the saturated vapor pressure of the pure solute at that temperature. ”May I ask if this sentence can be understood as meaning that in ASPEN’s property models, if the system is an ideal system, it is not necessary to specify a Henry component?
Henry’s law in Aspen seems to refer to poorly soluble gases or critical gases
Yes, so I still added the Henry parameter and set the Henry component
