Type of article: Article

Summary

A SYSTEM, OPERATED AT AMBIENT TEMPERATURE, PURIFIES HELIUM TO 99.999% WITH A RECOVERY RATIO OF HELIUM OF 99%. THIS SYSTEM CONSIST OF PSA (PRESSURE SWING ADSORPTION), MEMBRANE, HALOGENATED HYDROCARBON REFRIGERATOR, AND COMPRESSOR. THE PSA PURIFIER HAS ADSORPTION TANKS WHICH CONTAIN ACTIVATED CARBON AND SYNTHETIC ZEOLITE. IT CAN PURIFY HELIUM GAS WHICH IS CONTAMINATED WITH WATER, CARBON DIOXIDE, OXYGEN, ARGON AND NITROGEN TO 99. 999% HELIUM. THE MEMBRANE PURIFIER CONSISTS OF A MODULE WHICH CONTAINS MANY HOLLOW FIBERS OF CELLULOSE ACETATE. THIS SYSTEM CAN SEPARATE IMPURE COMPONENTS FROM HELIUM GAS, WHICH ARE CONDENSED IN THE MEMBRANE, AND EXHAUSTED. WATER IS CONDENSED IN THE HALOGENATED HYDROCARBON REFRIGERATOR AND EXHAUSTED. THEN IT IS ADSORBED BY PSA TO A CONCENTRATION WHERE THE DEW POINT IS BELOW 203 K (-70 DEG C).
