Abstract

The design of a plant for the liquefaction of gases at extremely low temperatures can be investigated with many-variations in cycle arrangements, choice of working fluid, operating pressures and component characteristics. One has the problem of judging the reasonableness of the choices made, In a recent paper Gifford1 discusses in general terms the requirements for the optimum plant for the liquefaction of parahydrogen, pointing out that:
  1. 1)

    Vapor cycle refrigeration should be used for cooling to approximately 140°K.

     
  2. 2)

    Expansion device refrigeration should be used for cooling from approximately 140°K to lower temperatures.

     
  3. 3)

    Care should be exercised to avoid use of refrigerants generated at low temperature for cooling at a much higher temperature.

     
  4. 4)

    As many steps of refrigeration levels should be used as is feasible.

     
  5. 5)

    Great care should be taken to optimize the system for the cooling below 80°K since most of the compressive work will be required there.
