By well known request, the nationwide Bureau of criteria used to be back a bunch to a convention on cryogenic engineering on August 19-21, 1957. related conferences have been held the following in 1954 and 1956. The reputation of over 40 papers for this convention used to be definitely an indication of the expanding job and curiosity during this engineering box. There turns out no doubt that it'll keep growing, justifying the necessity for annual conferences. To make the court cases extra attention-grabbing an try out was once made to incorporate up to attainable of the overall dialogue which each one paper. to procure person reprints of a person specific paper, please touch the authors without delay. 1957 CRYOGENIC ENGINEERING convention COMMITTEE B.

Although, in effect, heat enters at the base of each column and is removed at the top, the section in between containing the contact trays is essentially adiabatic, except for heat influx from the atmosphere. As an example, itemized data are presented in Table IV for the estimated irreversibilities incurred in the double column system of a Heylandt plant producing liquid oxygen.

46- A-5 THE REVERSIBLE SEPARATION OF MULTICOMPONENT MIXTURES H. M. Scofield Linde Company Division of Union Carbide Corporation Tonawanda, New York Introduction The concept of reversible rectification of binary gas mixtures is well known and has been applied often to define the thermodynamic limits of binary separations. An extension of this concept to multicomponent mixtures is quite possible, and a preliminary paper on the reversible separation of multicomponent mixtures was given at this conference last year.

Note that the largest difference in irreversibility between any individual component in the actual and ideal cycles is in the expansion engine, although the efficiency of -39- the practical engine (calculated on the basis of actual enthalpy drop divided by the enthalpy drop for isentropic expansion) is approximately 80 per cent.
