MRN - yes and no, when an azeotrope forms it cannot be separated but in this case PG forms an azeotrope with excess water present (not sure of the percentage - would have to look it up) that can evaporate. The azeotrope of PG just dictates the amount of water that PG can bind. Ethanol forms a 95% azeotrope with water, isopropyl alcohol forms a 91% azeotrope. If you put in more water than can be used to form the azeotrope it can evaporate as water vapor. The PG water azeotrope has a higher (always get this one wrong too) vapor pressure than water so water will evaporate first. If you have a very dry environment in your chamber you could exhaust the excess water but usually there is such an abundance of liquid to space that it will last a long time. In order to pull this off you need a suitable container for the PG/water mixture that will not spill out on your reeds. As mentioned, cigar humidors often use this to keep a 60%-70% RH for cigars.
