Abstract

The present investigation conducts on two different methods of cryogenic helium purification processes with the identical input (1.50%v/v N2 impurity) and output (grade 4.5). Accordingly, exergy analysis has been performed with experimental data on two kinds of commercial purifiers, viz., an integrated liquefier-purifier (cryocondensation) and a cryosorption purifier. The current study evaluates quantitatively the superiority of cryosorption purifier and assesses the exergy performance of helium liquefier on being integrated with different methods of purification systems. The key findings are useful for selecting, augmenting, and developing an efficient purification process.
