Abstract

The Helium Refrigerator/Liquefier (HRL) plant is normally operated with helium gas having purity better than 99.999 % by volume which is equivalent to having < 10 PPM (parts per million) impure gas in the helium stream. In the process of gas transfer or due to some other processes before reaching to cold box of helium plant, impurity level sometimes can reach to as high as 500 PPM averaging to about 100 PPM. For HRL operating for significantly longer duration and producing larger liquid helium for application, these internal purifiers are not sufficient. Hence, external to the cold box of helium plant, a dual-bed purifier operating at 80K is used for continuous operation of purification process. The sizing and layout of pipe lines will affect the pressure drop and flow controllability of the operation of purifier, which will be analyzed. Different loads like, pressure of the fluid and thermal stress will be analyzed.
