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. The heating element is controlled by a control unit responsive to a thermal sensing element disposed in the interior of the housing and arranged to monitor the temperature of the portion of housing in contact with the vaporized gas zone.

An apparatus for vaporizing a mixture of two liquefied gases in chemical equilibrium with a binary compound thereof comprising in combination: (a) an enclosed elongated vessel for containing the mixture to be vaporized, said vessel being defined by a generally vertically disposed shell having spaced walls defining a lower liquid zone and an upper vaporized gas zone; (b) liquid supply means in fluid communication with the liquid zone of said vessel adapted to pass the mixture to be vaporized as a liquid from a supply source into the vessel; (c) a generally vertically disposed heating element in said vessel and extending downwardly through the vaporized gas zone of said vessel and terminating above that portion of the liquid zone communicating with said liquid supply means, said heating element being adapted to supply sufficient heat to vaporize a gaseous mixture from said liquid zone; (d) a housing disposed about said heating element in spaced relationship thereto the space between said housing and said heating element containing a medium for transferring heat from said heating element to said vaporized gas zone and to said liquid zone through the walls of said housing; (e) at least one thermal sensing element disposed in the interior of said housing and arranged to monitor the temperature of said housing which is in contact with the vaporized gas zone; (f) a control unit responsive to said thermal sensing element and operatively connected to said heating element for adjusting the temperature of the housing which is in contact with the vaporized gas zone; and (g) means for removing the gaseous mixture from the vaporized gas zone of said vessel.
