THE NATIONAL BUREAU OF STANDARDS

Functions and Activities

The functions of the National Bureau of Standards are set forth in the Act of Congress, March

3, 1901, as amended by Congress in Public Law 619, 1950. These include the development and

maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards: the determination of physical constants and

properties of materials; the development of methods and instruments for testing materials, devices,

and structures; advisory services to government agencies on scientific and technical problems: in- vention and development of devices to serve special needs of the Government; and the development

of standard practices, codes, and specifications. The work includes basic and applied research,

development, engineering, instrumentation, testing, evaluation, calibration services, and various

consultation and information services. Research projects are also performed for other government

agencies when the work relates to and supplements the basic program of the Bureau or when the

Bureau's unique competence is required. The scope of activities is suggested by the listing of

divisions and sections on the inside of the back cover.

Publications

The results of the Bureau's work take the form of either actual equipment and devices or published papers. These papers appear either in the Bureau's own series of publications or in the journals

of professional and scientific societies. The Bureau itself publishes three periodicals available from

the Government Printing Office: The Journal of Research, published in four separate sections,

presents complete scientific and technical papers; the Technical News Bulletin presents summary

and preliminary reports on work in progress; and Basic Radio Propagation Predictions provides

data for determining the best frequencies to use for radio communications throughout the world.

There are also five series of nonperiodical publications: Monographs, Applied Mathematics Series,

Handbooks, Miscellaneous Publications, and Technical Notes. information on the Bureau's publications can be found in NBS Circular 460, Publications of the

National Bureau of Standards ($1.25) and its Supplement ($1.50), available from the Superintendent

Abstract

Published data have been used to calculate K factors for the

hydrogen-nitrogen system over the liquid-vapor range of 68. 2 to

122. 2°K, and 10 to 225 atmospheres. K factors are presented

graphically for eleven isotherms within this range.

Published data on the solid-gas and solid-liquid regions are

presented separately as composition versus pressure at constant

temperature.

A bibliography of 250 references pertaining to the hydrogennitrogen system is included.

1. Introduction

1. 1 Purpose

Hydrogen gas for liquefaction frequently contains large amounts

of other gases. Purification of these various hydrogen sources requires considerable knowledge of the physical equilibria of the systems

involved. Many theoretical studies have attempted to explain and predict the non-ideal behavior of these systems with varying degrees of

success.

An initial step in the study of physical equilibria logically

demands a review of current knowledge. In this, the first of a series,

the hydrogen-nitrogen system is examined. The purpose of this paper

is to determine what is known about the physical equilibria relationships and to present a thorough compilation of known related data for

this system. It is hoped that this paper will thus provide a firm

basis for the conduct of related research programs and place in the

hands of the design engineer the "best" information now available.

Future publications in this area will be concerned with the

physical equilibira of hydrogen and other important components.

1. 2 Organization

The information is presented in three principal parts: (1)

physical equilibria with major emphasis on vapor-liquid equilibria,

(2) properties related to physical equilibria, and (3) a bibliography

of references. Some discussion is presented with Part (1). The

information of Part (2) is presented in tabular form, including the

source of the data. Part (3), the Bibliography, lists the references

alphabetically by the first author.

1. 3 Scope

The scope of this work is as follows: a thorough literature

search, as summarized in NBS Technical Note No. 56, revealed much

of the pertinent data; such data were abstracted and presented in the

form of K-factor charts and as a bibliography of references for related

areas of interest. The lists searched are presented in the above reference and will not be enumerated here. They were, however, brought

up to date, July i960.

1.4 Acknowledgements

The authors especially appreciate the aid of the staff of the

Data Center of the National Bureau of Standards Cryogenic Engineering Laboratory, who provided the majority of the original papers for

review.

2. Survey of Literature

The literature search revealed six important references for

hydrogen-nitrogen vapor-liquid equilibria. There were Alters and

Eubanks (4), Gonikberg, et al. (91), Maimoni (166), Ruhemann and

Zinn (212), Steckel and Zinn (225), and Verschoyle (236). K-factor

charts were prepared from data taken from these references. In all

but two cases (4, 166), the data had to be re-interpreted to arrive at

K-factors.

Two important sources of solid-gas and solid-liquid data were

found. These were Dokoupil et al. (57) and Petit (196). This information is presented separately as charts of concentration versus pressure

at constant temperatures.

No related physical data are presented in this report; only the

references for such material are listed. Other areas so covered include adsorption, diffusion, purification processes, solubility relationships, density and compressibility data, equations of state, thermodynamic and transport properties, P-V-T data, critical constants,

virial coefficients, Beattie-Bridgeman constants, techniques of

analyses, and various processing references. Such material for the

pure components as well as for mixtures of hydrogen and nitrogen is

included in many cases.

3. Discussion of Available Data

For this system one could expect the vapor-liquid data, if

complete, to range roughly from the triple point temperature of

nitrogen to the critical temperature of nitrogen (63. 1° to 126. 2° K).

The references presented in this report provided data for eleven

isotherms between 63. 2°K to 122. 2°K. The isotherms so presented

are 63.2°, 68.2°, 78°-79°, 83.3°, 88.2°, 90°, 95°-95.4°, 107.7°,

109°, 113° and 122. 2°K. (Rather than take an average temperature
for the 78°-79°, 83°-83. 3°, and 95° -95. 4°K values, the equilibria

data for each narrow range are plotted as one isotherm. ) Thus, the

data available do present a rather complete picture of the vapor -liquid

equilibria for this binary system.

The solid-liquid region has been explored from 20° to 32°K

and from 12 to 35 atmospheres. The solid-vapor region has been explored from 25° to 70°K and from 1. 3 to 50 atmospheres.

The P-T region covered by published data is presented in

Figure 1. This figure indicates that this system has been rather

thoroughly explored by the several investigators. (The data for the

hydrogen P-T diagram were taken from Johnson (122) and from

Woolley, Scott and Brickwedde (248). The data for the nitrogen P-T

diagram were also taken from the former reference).

The original data were treated to arrive at the corresponding

K-factors. K is defined as y/x where y is the mole fraction of one

component in the vapor phase and x is the mole fraction of that component in the condensed phase. K-factors were calculated for each

component as a function of pressure and temperature. After plotting

the K-factors derived from the various investigators, a smooth curve

was drawn for the given isotherm. Finally, the smoothed individual

K-factors were transferred to a plot of K versus pressure with

temperature as a parameter.

It is not the purpose of this report to present a test of the data

for thermodynamic consistency. Maimoni (166) has performed such

tests with much of the data herein presented. Maimoni has corrected

Verschoyle's data by using new values for the vapor pressure of

nitrogen. In this article the original data of Verschoyle are given.

As pointed out also by Maimoni, the data of Ruhemann and Zinn differ

appreciably from other published values.

Of the data analyzed, the K-factor at the lower pressures

showed the most scatter. This was true primarily for the hydrogen

K-factor; less scatter was noted for the nitrogen K-factor. Undoubtedly this stems partly from the analytical techniques used.

It must be emphasized that this report is based entirely on the

original data of the investigators. These data, in some cases, have

not been tested for thermodynamic consistency, and should be used

only with thorough awareness of this fact.

4. K-Factor Charts

Presented in Tables I through VII in the Appendix are the data

used in computing K-factors.

Figures 2 and 3 are plots of the K-factors of hydrogen and

nitrogen, respectively. Dotted portions on these figures indicate

extrapolated areas. (These extrapolations were performed mainly by

the original authors. ) Figure 4 shows, finally, the curves for both

hydrogen and nitrogen as taken from Figures 2 and 3. In Figure 4,

hydrogen K-factors are situated above the line K = 1, and nitrogen Kfactors are below this line. The significance of the fact that the two

curves meet at K = 1 is a characteristic of the plait point. (Verschoyle

discusses the plait point. ) Thus, the line K = 1 represents a locus of

the plait points. The plait point for the 68. 2°K isotherm, not shown

in Figure 4, was estimated by Verschoyle to be at 340 atmospheres.

The use of these charts might be as follows: for a given system

pressure and temperature, K-factors could be read from Figure 4 and

the phase compositions found by the following equations.

Similarly, dew points and bubble points of given hydrogen-nitrogen

mixtures can be calculated.

The critical constants as derived from the various isotherms

are not shown on any of the figures. Verschoyle does comment about

the critical points for his isotherms. Table II lists his critical

constants.

5. Solid- Liquid Equilibria

Shown in Table VIII are the data of Petit (196). Six isotherms

relating liquid phase composition and system pressure are shown in

Figure 5.

6. Solid-Gas Equilibria

The data of Dokoupil, Van Soest, and Swenker (57) are given in

Table IX. The data have been plotted to derive gas phase composition

as related to total pressure for eight isotherms between 25° and 60° K.

Table X presents the data in this form. Figure 6 is a plot of the data

of Table X.
