ABSTRACT:
A method to deliver ultra high purity helium gas to a use point without need for further pressurization of helium gas after it is warmed or vaporized, wherein gaseous helium, having a purity which can be less than that of the product, is passed in heat exchange relation with cold helium to warm or vaporize and thus pressurize the helium while simultaneously being cleaned of impurities, and the resulting helium gas from both sources is delivered as ultra high purity helium gas to the use point.
