ABSTRACT:
The invention relates generally to a gas purification system for the purification of noble gasses and nitrogen. An improved method of purification generally includes the following steps: (a) heating an impure gas; (b) contacting the impure gas with an impurity sorbing material to produce a purified gas; (c) cooling the purified gas to a temperature less than about 100.degree. C.; and (d) contacting the purified gas with a hydrogen sorbing gas to remove residual hydrogen. The system includes an improved heat exchange apparatus for cooling the purified gas and a low temperature hydrogen sorption apparatus.
