Abstract DRAWING 1. A METHOD OF DETERMINING AND REMOVING OXYGEN FROM A GAS STREAM INERT TO HYDROGEN, WHEREIN SAID OXYGEN CONCENTRATION IS LESS THAN 1% BY WEIGHT, COMPRISING: PASSING SAID GAS THROUGH A SORBENT MATERIAL SELECTED FROM THE GROUP CONSISTING OF MAGNESIUM PERCHLORATE AND THE METAL ALUMINOSILICATES FOR DRYING SAID GAS TO A PARTIAL PRESSURE OF WATER VAPOR NO MORE THAN A FEW HUNDREDTHS OF A MILLIMETER OF MERCURY; PASSING SAID GAS AT ABOUT 3 ATMOSPHERES ABSOULTE PRESSURE THROUGH A COIL OF TUBING COMPOSED OF A MATERIAL COMPRISING PALLADIUM; CONTACTING THE OUTSIDE SURFACE OF SAID COIL OF TUBING WITH ESSENTIALLY PURE HYDROGEN GAS AT ABOUT 6 ATMOSPHERES PRESSURE AND ABOUT 200*C. TO DIFFUSE A SUFFICIENT ANOUNT OF HYDROGEN THROUGH THE WALL OF SAID TUBING TO CHEMICALLY COMBINE WITH SUBSTANTIALLY ALL OF SAID OXYGEN AND FORM WATER VAPOR; COOLING SAID GAS TO AND CONTINUOUSLY MONITORING THE CONDENSATION-POINT TEMPERATURE OF WATER VAPOR IN SAID GAS IN ORDER TO DETECT THE MOISTURE CONCENTRATION RESULTING FROM SAID CHEMICAL COMBINATION OF OXYGEN WITH HYDROGEN WITHIN SAID GAS; AND FURTHER COOLING SAID GAS TO ABOUT 1*C. ABOVE THE FREEZING POINT OF WATE AT ABOUT 3 ATMOSPHERES ABSOULTE PRESSURE TO CONDENSE A MAJOR PORTION OF SAID WATER VAPOR THEREFROM AND SUBSEQUENTLY PASSING SAID GAS INTO CONTACT WITH A SORBENT MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE METAL ALUMINOSILICATES AND MAGNESIUM PERCHLORATE TO REMOVE SUBSTANTIALLY ALL OF SAID WATER VAPOR AND THEREBY PRODUCE A SUBSTANTIALLY OXYGEN FREE GAS.

TO DIFFUSE A SUFFICIENT ANOUNT OF HYDROGEN THROUGH THE WALL OF SAID TUBING TO CHEMICALLY COMBINE WITH SUBSTANTIALLY ALL OF SAID OXYGEN AND FORM WATER VAPOR; COOLING SAID GAS TO AND CONTINUOUSLY MONITORING THE CONDENSATION-POINT TEMPERATURE OF WATER VAPOR IN SAID GAS IN ORDER TO DETECT THE MOISTURE CONCENTRATION RESULTING FROM SAID CHEMICAL COMBINATION OF OXYGEN WITH HYDROGEN WITHIN SAID GAS; AND FURTHER COOLING SAID GAS TO ABOUT 1*C. ABOVE THE FREEZING POINT OF WATE AT ABOUT 3 ATMOSPHERES ABSOULTE PRESSURE TO CONDENSE A MAJOR PORTION OF SAID WATER VAPOR THEREFROM AND SUBSEQUENTLY PASSING SAID GAS INTO CONTACT WITH A SORBENT MATERIAL SELECTED FROM THE GROUP CONSISTING OF THE METAL ALUMINOSILICATES AND MAGNESIUM PERCHLORATE TO REMOVE SUBSTANTIALLY ALL OF SAID WATER VAPOR AND THEREBY PRODUCE A SUBSTANTIALLY OXYGEN FREE GAS.
