THE PURIFIER SYSTEM FOR HELIUM CRYOGENIC PLANT IN NSRRC
2012
A cryogenic adsorber is a purifier cooled with liquid nitrogen that is used to trap impurities from gaseous helium in the helium cryogenic system. The output purity can be decreased to less than 5 ppm and the dew point to 62 ℃. The maximum rate of flow of each adsorber is 95 Nm 3 /h. We installed five cryogenic adsorbers in the cryogenic system and completed its testing in 2011; five additional cryogenic adsorbers will be installed in 2012. The configuration, installation, test results and operation of an cryogenic adsorber system are reported herein.
