In this paper, comparative studies between Linde-Hampson and Claude cycle for the liquefaction of oxygen have been completed. PRO/II with PROVISION release 2021. 1 from AVEVA company (Cambridge, UK) was used, and Peng-Robinson equation of the state model with Twu's alpha function was selected for the modeling of the condensation of oxygen. When using Claude liquefaction cycle, we could reduce the total compression power by 59.51% for the comparison of Linde-Hampson cycle.
