Cryogenic system, gas separation and liquifaction Research Paper

Cryogenic system, gas separation and liquifaction - Research Paper Example It is used in the production of gases like O2, N2, Argon, Neon, Krypton, and Xenon. Cryogenic separation has proved to be economical, increases the difference in the boiling points of constituents, process takes up large quantities and achieving purity of gases is tenable. Cryogens like LOX, LH2 are used in rocket propulsion while LH2 is being considered for automobile (Flynn, 2005). LN2 is used as a coolant in cryogenic systems as well as gas refrigeration in cases where low-temperature gases are required. Refrigeration makes use of the principle of heat change in the system, which is equal to the total internal energies (U) and the work (W); . It makes of the first and second Law of thermodynamics. Cryogenic systems are closed cycle systems comprised of the compressor, liquid containers, expander, and heat exchanger. Analysis of cryogenic process follows the Joule-Thompson expansion, which is an isenthalpic expansion process;  (Barron, 1985). The systems are engineered to obey Laws of physics from the field of thermodynamics, heat transfers and
