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. The level of the liquid phase is maintained above a predetermined level and sufficient heat is supplied to vaporize a portion of the liquid phase at a temperature greater than the dew point temperature corresponding to vapor having substantially the same composition as the known composition of the liquefied gas mixture from the supply source at known pressure, thereby forming a gaseous mixture. The gaseous mixture is removed from the vessel. |
