Abstract
A cryocooler-based gas scrubber, or cryocooler-based gas purifier, utilizes the cooling power of a cryocooler to cool and condense cryogen gas forming coalesced impurities which are then filtered through a filter matrix, such as for example a fiberglass filter matrix. The scrubber may further comprise a counter-flow heat exchanger for warming the purified gas prior to dispensing at an outlet for storage or consumption.
