LIQUEFACTION OF HELIUM & MAGNETIC COOLING  Liquefaction of Helium by Collins’s Cryostat Principle (i)  Polytropic expansion for pre-cooling (ii) Throttling for liquefaction. Liquefaction of helium(Fig.4) uses normal boiling liquid nitrogen for pre-cooling before the helium enters the first cascade heat exchanger. Since helium liquefies at a lower temperature than that of even hydrogen, more number […]

LIQUEFACTION-NITROGEN & HYDROGEN Liquefaction of Nitrogen A modified Claude cycle is used for the liquefaction of nitrogen. It has the used advantage of both the turbo-ex pander and Joule Thomson valve [Fig.3(a)]. Three heat exchangers are used in Claude cycle. Whereas, two numbers of heat ex changers are used in this liquefier. Last two heat […]
