Theoretically, when the vapor pressure of water and the solution pressure of dissolved gases appreciably exceed the pressure imposed on a system, the gases become insoluble. Water simply cannot contain dissolved gases at saturation temperatures, such as 212°F, at atmospheric pressure or 250°F at 15 psig (assuming sea-level conditions).
