Abstract: A heating apparatus for the vaporization of a mixture of two liquefied gases in chemical equilibrium with a binary compound thereof includes a vertically disposed enclosed vessel having a lower liquid zone to which the mixture to be vaporized is supplied as a liquid from an external supply source and an upper vaporized gas zone from which gas can be removed for use. A vertically disposed heating element, which may be an electric heating element, steam tube, and the like, extends downwardly in the vessel through the vaporized gas zone and terminates above the portion of the liquid zone communicating with the liquid supply and is adapted to supply sufficient heat to vaporize a gaseous mixture from the liquid zone. A housing is disposed about the heating element in spaced relationship thereto and a heat transfer medium is contained within the space.

Abstract: An apparatus and method for the vaporization of a mixture of two liquefied gases in chemical equilibrium with a binary compound thereof. The apparatus comprises an enclosed vessel having a liquid zone and a vaporized gas zone. A liquid supply means, in fluid communication with the liquid zone, passes the mixture to be vaporized as a liquid from a supply source into the vessel. A heating element, having a housing disposed about it, extends downward through a portion of the interior of the vessel and is adapted to supply sufficient heat to vaporize a gaseous mixture from the liquid zone. Means for superheating and removing the vaporized gaseous mixture from the vessel are provided. The method of vaporization comprises withdrawing the mixture as a liquid from a supply source and passing it into the vessel to form a liquid phase.
