PREFACE

The Cryogenics Division of the National Bureau of Standards,

with support from the American Gas Association, is engaged in a program to provide input data and computational methods for physical and

thermodynamic properties of the constituents of liquefied natural gas

mixtures (LNG). These thermophysical properties are the basis of all

LNG technology. All operations such as liquefaction, separation,

storage, pumping, transport, custodial transfer, and regasification

will benefit from accurate data. As the commercial value of LNG

depends on its heat of combustion, the densities of LNG mixtures and

other requisite properties are important data.

The compositions of LNG mixtures vary widely, depending on

the source and selective vaporization during handling. To predict

properties of mixtures, it is essential to know accurately the properties

of the pure components and of selected binary mixtures, so that the

excess property (over the mole- fraction average of the components)

can be examined.

The equation of state of pure components is an essential tool

in work on mixtures because from this single formulation there can be

obtained not only the density but also thermodynamic properties such as

the enthalpy and specific heats at any desired temperature and pressure

for which the component exists as a fluid.

A major contribution from this laboratory for computations on LNG and its components is the development of a simple, rational

equation of state which originates on the liquid-vapor coexistence

boundary, and gives a qualitatively correct behavior for derived specific

heats, especially about the critical point. A form of this equation was

used in our recently completed, comprehensive project on the major

Vll
component of LNG, namely methane, "The Thermophysical Properties

of Methane from 90 to 500 K at Pressures to 700 bar. " NBS Technical

Note 653, April, 1974.

In addition to the above publication, this laboratory has provided

accurate experimental data on the compressibilities, vapor pressures,

saturated liquid densities, specific heats, sound velocities, dielectric

constants, refractive indices, and viscosities of compressed and liquid

methane at temperatures down to 90 K.

A similar comprehensive project on ethane now is under way. The

present report makes use of available physical properties data to obtain

tables of thermodynamic functions, and provides the first of such tables

available for liquid ethane below its normal boiling point temperature

(184. 5 K). In this work we use a simplified and more highly constrained

version of the equation of state formerly used for methane. Auxiliary

functions also are improved to accommodate the enormous range of ethane

vapor pressures and saturated vapor densities. The use of these new

analytical descriptions of PVT data for ethane does not in any way invalidate the methods used to compute the thermodynamic properties of

methane in NBS TN 653. The equation of state used for methane in TN

653 had nine least- square s coefficients, and thereby gives a better representation of some of the experimental PVT data than does the present,

more highly constrained equation with only five such coefficients. For

ethane, the present equation of state is valuable because the available

PVT data are less precise (over the entire P(p,T) surface ) than tho se used for methane in TN 653. Further work on the equation of state has

been carried out to obtain the simplest possible form, amenable to corresponding states computations on mixtures. This work, "Equation of

State for Thermodynamic Properties of Fluids, " was submitted to the

NBS Journal of Research in October, 1974.

THERMODYNAMIC FUNCTIONS OF ETHANE*

Thermophysical properties are tabulated at integral

temperatures over the entire range of fluid states from 90

to 600 K along isobars to 700 bar. A new, rational equation

of state is employed for the first time. Thermodynamic

functions in the compressed liquid at T<T are obtained by

c use of specific heats C (T) along a high-pressure isobar.

1. INTRODUCTION

The economic importance of methane and ethane, as the major

components of liquefied natural gas (LNG), is well known. Our objective is to produce basic thermodynamic information, needed for the

prediction of properties of the constituents of liquefied natural gas mixtures. For the wide range of compositions encountered, it will be neces

sary to utilize accurate thermodynamic properties ofthepure components

We recently have published the properties of methane [25]. The

present work on ethane provides background on available physical properties data, and may serve engineering needs for thermodynamic

properties until such time as new physical data permit a revision of

the table s .

* This work was carried out at the National Bureau of Standards under

sponsorship of The American Gas Association.

1
All of the analytical formulations of physical properties data

in this report are new as compared with [25]. The major contribution

of present work is development of a rational equation of state. As in [25],

our description of the P(p, T) surface originates on a given liquid-vapor

coexistence boundary (vapor-pressure and orthobaric densities equations).

It yields a maximum in the specific heats C (p, T) at the critical point,

and has only five arbitrary coefficients to be found by least squares

from experimental P-p-T data. We give constants of this equation of

state both for methane and for ethane because uniform methods of

computation will be helpful with mixtures.

Some recent thermal data have been especially valuable for

our computation of the thermodynamic network. These are the ideal

gas functions of Chao et al. [8], and the low temperature specific heats

C (T) of Furtado along isobars [20].

Symbols and units of this report, listed in Appendix A, are the

same as for methane [25]. For equation of state (5) the gas constant is

R = (0.0831434) • (d ) bar/K, consistent with use of the dimensionless

density, p h d/d^_.

2. PHYSICAL PROPERTIES AND THEIR REPRESENTATION

2 . 1 Fixed- Point Constants

These values are listed in Appendix B. For methane, they are

taken from [25].

The triple-point temperature and pressure for ethane are from

our analysis of ethane vapor pressures [26]. The liquid density is a short extrapolation of the saturated liquid densities of Miller [48]. The

vapor density is given by intersection of our present virial equation of

state with our vapor-pressure locus [27].

The critical-point temperature and density for ethane were adjusted by examination of the critical isotherm from the present equa2
tion of state. Our value of T = 305.37 K agrees with the recent experic mental observation of Strumpf et al[68-a], namely T

c = 305.368 ± 0.005 K.

Our critical density, = 6. 74 mol/4 may be compared with 6. 83 ±

0. 07 mol/4 from [68-a], with 6. 79 ± 0. 02 mol/4 from [49], and with

6.87 mol/4 from [14]. Critical densities reviewed in [ 14, 17, 70]

range from 6.75 ± 0.07 to as high as 7.32 mol

/

-t , a s pr e ad of 8/o

.

Our critical pressure of 48. 755 bar at T = 305. 37 K may be compared with other authors by use of the slope of the vapor pressure

curve at the critical point, namely dP^/dT = 1. 04 bar/K. Most recently, for example, Douslin and Harrison [14] give = 48. 718 bar at

T = 305. 33 K.

c The reader should note that our "critical density" is essential for

the present equation of state to give a critical isotherm with no negative

slopes, (SP/d p)rp 2: 0. Our procedure is an altogether new method for

x c finding this characteristic constant, but may depend heavily on the analytical form of the equation of state used [29a]. It follows that our "critical density, " dc , should be regarded as a fitting parameter, and not necessarily as the best value for this characteristic constant.

2. 2 Melting Line and Vapor Pressures

For the melting line of ethane we have found only the rough data

of Clusius and Weigand to 42 bar [ 11] . In the Simon equation [25],

P = P + aT(T/T ) g -?

t I t we assumed e = 2, finding A = (1. 01325)- (2840. 0) bar from their data by

averaging P/ ! (T/T ) £

of our early form [23],

Table 1 for ethane compares the data.

After the present report was completed, we received the vapor

pressures of Regnier [58] from 80 to 135 K. His results for the liquid

were described in mm Hg by

log 10 (P) = 7. 75-881 /T.

The following Table 2 compares results from our present vapor pressure

equation (2) with his calculated pressures. If we use the ideal gas law to

obtain the vapor density, and obtain dP/dT from the above equation, the

Clapeyron equation gives the heat of vaporization independent of temperaa = 4. 7774 8580

ture. The Clapeyron equation is -

' Qvap =T- (dP/dT)- (v

- v

t ). From the above vapor pressure equation, P = exp[a - b/T], one obtains - (dP/dT) = b* P/T 2

At low pressures, v^ is negligible relative to Vg, hence via the ideal gas

law - , (Vg - vt ) = R-T/P.

Introducing the last two expressions into the first yields

Q-wan = b*R = 16.87 kJ/mol. V ct p

The smoothed experimental value of previous workers at 100 K is

17.3 ± 0.2 kJ/mol (Table 15). Regnier's duplicate pressure gages

agreed to 1% or better, but he makes no estimate of absolute accuracy.

The Orthobaric Densities

For the saturated liquid and vapor densities, o(T), we have

developed analytical expressions which are constrained to any given

boundaries, namely the triple and critical points [28], In eqs (3 -a) and

(3-b) the basic behavior is given by Y(p, T) = const. , and polynomials

on the right side are selected to describe small deviations.

The data of Table 4 are obtained from the virial and vapor pressure

equations [27], The heading PLANK/KAMB refers to [52]. The data

of Table 5 for ethane are compared with (3-b).

c) For the equation of state, we use the liquid-vapor, equilibrium (saturation) temperature T(T (p) as a function of density. Densities

are obtained from the following expressions for T rT (p) by iteration,

using eqs (3 -a) and (3-b) only to find the initial density. We shall

describe T^p) in two parts, according as p>p^. This simplifies the

design of constraints to the boundaries (vapor and liquid triple points).

At the critical point the two parts are continuous because the derivatives of all orders n, d

I1 T rT /dpn

, from each are zero. For each range

the dependent variable is

Y(T_(p)) = (T /T ct -1)/(T IT -1),

c c t and we use the following function,

U(c ) = - y (1/x-l/x ),. where

For the vapor range at a < 1 we need a modification for extremely low densities approaching the triple point. The form is selected for

For ethane the liquid saturation temperatures appear in Table 6,

the second and third coefficients B(T), C(T) are dimensionless. We

reduce temperature and density of the critical point, x = T/T , a =

c d/d^. Following initial research on the representation of these coefficients [27], we now have adopted McGlashan's formula for B (T),

2 . 5 The Equation of State

Data reproduced in the present report are summarized by Table

10. The locus of recent data is shown by Figure 1. From the data of

A. K. Pal we selected only twelve isochores at the highest densities,

runs Nos. 13 through 24 of Table 12, because they were found to be

self-consistent. An increase of all densities by 0. 5 percent than made

these PVT data compatible with data of other authors (Table 10) via

our equation of state. We finally used adjusted data of A. K. Pal

kindly provided by Professor R. Kobayashi, J. R. Ely, et al of the

Chemical Engineering Department, Rice University. We omitted the

data of Reamer et al because those of Douslin and Harrison are believed to be more accurate.

For background on this equation of state, the reader may refer

to our work on methane [25]. We consider density to be a parameter

in the description of P(T) isochores, Figure 2. (In Figure 3 we show

the well-known zero slope and curvature of the critical isotherm. ) For any density we obtain the liquid-vapor coexistence temperature

from our function for T CT (p), eqs (3-c, 3-d). Placing this in the vapor

pressure equation gives the coexistence pressure. The equation of

state thus is defined as a function of density on the coexistence boundary.

By subtraction we shift the origin to this boundary. Define the

variables - -

x(T) = T/T , c X (p) = T (p )/T

ct a c

Y (P , p,T)= (Z-l).x/p,

(4. 1868)- (4827. 2) J/mol.

3. 1 The Homogeneous Domain

With reference to Figure 9, we start our computations with ideal

gas values at zero density, and then integrate along isotherms by use

of the equation of state in the following relations,

3. 2 The Vapor-Liquid Transition

As discussed below, we have used this computation only as a check against experimental heats of vaporization, and for closedloop checks terminating on the saturated liquid.

We traverse the vapor-to-liquid "dome" of Figure 9 by use of the

Clapeyron equation, and Av = (v -v ), f e

AH = T. (dP/dT). Av, (16)

AE = AH - P. Av, (17)

AS = AH/T, (18)

where (dP/dT) is slope of the vapor pressure curve.

3. 3 Compressed Liquid States

Computations along isotherms which pass close to the critical

point, Figure 9, cannot be expected to be accurate, as discussed in

[25]. For ethane there is an additional problem for use of the

Clapeyron equation to enter compressed liquid states. At low temperatures the vapor pressures become so small that they have yet to

be measured accurately, and the saturated vapor densities obtained

17
here are correspondingly uncertain. We therefore have used the following procedure to compute around the critical point into the crosshatched region of Figure 9: We use the isobar of specific heats C (T) at P = 137. 895 bar

P b

from [20]. We then select = 340 K, obtaining (by integration along

T. )

H(T PJ = 25 737 -97 J/mol, S(T , PJ = 176.4384 J/mol/K.

We finally integrate along isotherm T as described among eqs (10)

through (18). On the saturated liquid boundary we compute the specific heat C rj.(T) of liquid along the coexistence path from the following

relation [61],

C

CT (T) = C

v

(P ’ T) T -( ap /5 T).(dp^/dT)/p^ , (19)

where (dp^/dT) is the slope of saturated liquid density vs. T.

4. TESTS AND COMPARISONS

4. 1 The P-p-T Compressibility Data

Deviations of experimental densities and pressures from the

smooth P(p, T) surface of the equation of state (5) are given in Table

12, using author identifications from Table 10. The data of Michels

[47] and Douslin [ 14] are highly precise, and the deviations generally

are systematic, as might be expected from an equation of state with

as little freedom as (5). Any inaccuracies in the liquid-vapor boundary will be propagated along calculated isochores because the equation

18
of state originates on this boundary. At high densities in the compressed liquid, the derivative BP/Bp becomes extremely large, hence pressure deviations should be ignored.

4. 2 Calculated P(p) Critical Isotherm

Table 18 gives a high-resolution examination of the P(p) critical

isotherm from equation of state (5). This was obtained by adjusting

the assigned critical point (p , T^) to eliminate negative slopes BP/3p

in the neighborhood of p . The selected critical point is within the

range of values found by previous workers.

4. 3 Heats of Vaporization and Closure Computation

The last column of Page 1 of Table 26 gives experimental heats of

vaporization from eq (7) for comparison with values in column Q, VAP

computed by the Clapeyron equation. The differences are plotted in

Figure 10 as (Q -Q ). xptl calc

Table 19 gives loop-closure computations for the saturated liquid.

Values for enthalpy in Column H_ and for entropy in Column S are obtained by computing around the critical point, whereas values in

Columns HC and SC are via the Clapeyron equation (see Sections 3. 2,

3. 3). The enthalpy differences are plotted in Figure 10 as (H . -H^ ) in which refers to computation around the C. P. by

calc Furt Furt

use of C (T) data of Furtado [201.

P

Heats of vaporization via the Clapeyron equation at low temperatures are uncertain by several percent (up to about 500 J/mol) due to

uncertainty in the vapor-pressure equation and the vapor densities.

In Table 16, moreover, we see that experimental heats of vaporization may differ by over 2 percent at 100 K, (about 350 J/mol). The

apparently large deviations seen in Figure 10 therefore do not exceed

known uncertainties. The heats of vaporization have not been used for

present computations.

19
4. 4 Heat Capacity for Saturated Liquid

The last column of the second page of Table 26 gives experimental

heat capacities for the saturated liquid from eq (8) for comparison with

values in column CS computed as described above in Section 3. 3. As

seen in eq (19), this is a difficult computation from which to obtain

high accuracy. We also have computed C a(T) = T* (dS^/dT), but prefer

to omit this further complication of present work.

4. 5 Specific Heats, C

^

(p, T)

Table 20 compares specific heats of [20] at constant pressure

with values calculated by present methods. Except near the sharp

maxima in Cp in the critical region, the differences generally do not

exceed combined uncertainties of a few percent.

4. 6 Comparison of Enthalpies

Table 21 compares our saturated liquid enthalpies (obtained by

computation around the critical point) with results of Tester [70]. From

low-temperature specific heat data on the solid, and the heat of fusion,

he obtained the third-law entropy of liquid at the triple point. He then

used experimental C a

(T) data, liquid densities and dP/dT from the

vapor-pressure equation to obtain AH(T) on the liquid coexistence path.

Table 22 compares enthalpies of three authors for the homogeneous domain at a few, selected (P, T) points. To make use of the values

of Eubank et al. , we have added H°(T) obtained from Tester. This comparison shows that our results from the present very simple equation of

state are consistent with the work of other authors.

4. 7 Speed of Sound for Saturated Liquid

Figure 11 compares the speed of sound W for saturated liquid

from Table 26 of present work with the experimental data of Poole and

Aziz [53], Positive curvature of our calculated results below the boiling point (184. 55 K) suggests that derivatives of our P(p, T) surface are

20
not sufficiently accurate in the compressed liquid. Below 105 K the

calculated dependence of the saturated liquid densities on the temperature in Table 6 also has a positive curvature, which probably is qualitatively incorrect.

5. TABLES OF PHYSICAL AND THERMODYNAMIC

PROPERTIES

5. 1 Calculated P- p -T Isochores and Isotherms

A selection of calculated isochores and isotherms is given by

Tables 23 and 24. They are useful to examine behavior of the surface

generated by the equation of state, and to supplement the isobars of

Table 27 in obtaining P-p-T values and their derivatives.

5. 2 The Joule-Thomson Inversion Locus

Table 25 gives our calculated P-p-T locus for the J. T. inversion,

(ST /^P)h = These results are obtained from the equation of state

under the condition, T* OP/ST) = p*(dP/dp).

5. 3 Thermophysical Properties of the Saturated Liquid

Table 26 gives physical and thermodynamic properties for the

saturated liquid. Column headings are interpreted on the first page

of this table.

5. 4 Thermophysical Properties Along Selected Isobars

Table 27 gives physical and thermodynamic properties on isobars,

as computed by methods of Section 3. Explanations for the table are

given on the first page. This table is extrapolated beyond the range of

P-p-T data used for adjusting the equation of state (P ~ 350 bar).

6. COMMENTS AND RECOMMENDATIONS

Uncertainty of the saturated liquid densities (Table 3) is estimated

to be 0. 1 percent from 90 to 140 K. Greatest uncertainty, approaching

0. 5 percent, exists in mid-range (160 to 250 K) where no experimental

data were found. Whereas several sets of precise data exist approach21
ing the critical temperature, we have not been able to represent them

with a function of simple form to better than 0. 2 to 0. 3 percent [28].

Saturated vapor densities at very low temperatures are uncertain

by several percent because they have been estimated by use of the

vapor-pressure equation which is uncertain by at least 2 percent at

these temperatures [26], and the virial equation of state. The latter

is extrapolated below the range of data for the virial coefficients where,

however, we approach ideal gas behavior [27].

Our calculated densities (Table 27) over the homogeneous domain

(

n

<0 , or T>T ) are uncertain by an estimated 0. 2 percent, except for r c c the critical region (p r /3<p<2* p c at 0. 9* T C <T<1. 2- T c ) where deviations

from experimental data may exceed one percent, Table 12. For the

compressed liquid at low temperatures, densities probably are uncertain by about 0. 2 percent (adjusted P-p-T data of A. K. Pal [54]).

Uncertainty of enthalpy differences is most difficult to estimate.

Along isotherm T^ of Figure 9, we compute Cp(p, T) at point (T^, P^)

within one percent of the experimental value from [20]. For the homogeneous domain, having an adequate density of P-p-T data, therefore,

the uncertainty of enthalpy differences probably is comparable with

that estimated for methane [25], namely about 2 percent. For compressed liquid, as seen in Section 4 above, however, the uncertainty

may be several-fold greater.

The purpose of this report has been, in part, to find the inadequacies in physical properties data needed for thermal computations.

Some recommendations can be made, based on the inaccuracies shown

in Section 4 above. The possible methods for preparing a thermodynamic network are so numerous and varied, however, that the reader

may wish to draw his own conclusions. We make only the following

simple observations and recommendations:

22
1) The melting line is poorly defined. Accurate P-p-T data for

the freezing liquid would provide a boundary for the equation of state.

The triple-point temperatures which have been published are highly

discordant. Extrapolation of the P(T) melting line to zero pressure

might yield a reliable value. This is needed especially for the vapor

pressure equation.

2 ) More accurate P-n-T data (better than 0. 1% in density) are

needed for the low-temperature compressed liquid. From such data

accurate saturated liquid densities may be obtained by intersection

with an accurate vapor-pressure line.

3) Accurate densities for the saturated liquid are needed in midrange where few if any experimental data exist.

4) Accurate vapor pressure measurements apparently exist

only from 200 K (2 atm) upwards. These could be extended down to

150 K (0. 1 atm) by use of the "air dead-weight gage. " Their use might

give a vapor pressure equation with more reliable derivatives, dP/dT,

over the entire range.

5) Sound velocity measurements over a wide range, as well as additional specific heat measurements, e. g. C v (p, T), would provide

further tests of the thermodynamic computations.

'

This has only two temperature -dependent terms (in addition to pRT),

which is the minimum number needed to describe the sigmoid shape of

isochores [ 6 1 ] in the range p^<o<2* p^, Figure 2. Each of these terms

is zero on the coexistence boundary at T = T (p). a The first term, §(p, T), is shown by Figure 5. It is linear

2 . 2

(3 $/3 T = 0) on the coexistence boundary. It gives a critical isochore

which is linear at the critical point because C(p) = 0 along this isochore.

The second term, Y(p, T), is shown by Figure 6. It starts with

2 . 2

infinite curvature (3 Y/3T ) on the locus of temperatures, 0(p), inside

the coexistence envelope of Figure 4. Sufficiently far away from the

2

critical point it behaves like 1/T , found in the well-known BeattieBridgeman equation.

2 2

The sign of the curvature (3 P/BT ) of isochores at the coexistence boundary is determined uniquely by the sign of C(p). Figure 7

shows the behavior of B(p) and of C(p) for methane. The root in C(p)

at p/p =1.9 was found by least squares both for methane and for

ethane. It then was introduced as the non-linear constant, C , in the

o equation of state. This constraint is valuable. In its absence we quite

often have failed to obtain any such root from P-p-T data by least

squares. Figure 8 shows the presumed behavior of C(p) for hydrogen

(a double root near p/p = 1. 9), needed to give the observed positive

curvature of isochores in the compressed liquid at the lowest temperatures [13, 21],

33
APPENDIX C. (Continued)

The critical isotherm from eq. (5) necessarily has zero slope,

dP/dp = 0, at the critical point, Figure 3. This follows from our

definitions of T rr (p), 0(p), $(p, T) and Y(p, T). The second derivative,

2 , 2

3 P/dp , also is zero because the vapor pressure here is expressed

as a function of T rj (p). Our detailed examinations of this isotherm

show however, that small changes in the assigned critical point (q , T ) c c give rise to irregularities nearby at p § p . Adjusting the critical

density to p =6. 74 mol /

H

yields a well-behaved critical isotherm

c having no negative slopes, i. e. dP/dp^O.

Specific heats along the critical isotherm of Figure 4 are comput2 2

ed by integrating the curvatures of isochores, (d P/dT ), in eq. (11),

starting at p = 0. Curvatures from the term C(p)‘ Y(p, T) in the equation of state at first increase sharply (with negative sign) as p-*p , bec come zero at p = p , then strongly positive at first for p>p , finally

c c diminishing at still higher densities. This behavior is seen along the

critical isotherm in Table 24. It gives a maximum in C (p, T) at the v

critical point via eq0 (11).

NAME /- J R . D . Goodwin

DATE Julv 7 , 1773

This is the first of several reports planned on the physical properties of ethane.

Our ultimate purpose is to compute tables of thermodynamic functions over the entire

range of fluid states. We first will discover regions where data are inadequate or

lacking by attempting to compute provisional tables based on existing data.

Accurate vapor pre s sure s, and a proper analytical representation of these data, are essential for computing heats of vaporization via the Clapeyron equation.

In this note we give a limited bibliography. Not all of these references were

available at this writing. We compare several sets of data by use of our newtonanalytic vapor pressure equation. We make a choice of the best for least squares, and

we give deviations from this selected equation.

At the triple point near 90 K the vapor pressure of ethane is about 0.00001 atm

(10 LL-atm). Experimental methods therefore differ for the range below one atm

( 184 . 5K) and for the range of higher pressures to 48 atm at T = 305 K.

Data to about I960 are reviewed by Tester [19], who selected the representation of Barkelew et al. [3] for the entire range from triple- to critical point.

Below one atm the data to 1964 are reviewed by Ziegler et al. , who give their

own, high quality set of data computed for thermodynamic consistency with all related or derived data, in a work for the National Standard Reference Data Program [23],

More recently we have the measurements of Carruth, obtained by the gas saturation

flow technique, employing a flame ionization detector for analysis of the gas mixture [4]. See also J. J. Chen et al. (Rice University), paper G-l, 1972 Cryogenic

Engineering Conference, on the same technique.

For high pressures the only new data of which we presently are aware are those

of Pope (Table 25) [ 13], and those attributed to Dr. A. K. Pal by Pope [13] in Table 31.

For these latter data there is no description of experimental method.

After this note was written we received the new precise measurements of

Douslin and Harrison [24], and therefore have recomputed our results including these

data. Douslin and Harrison note especially the new, precise measurements of

Miniovich and Sorina [25], which were not available to us at this writing.

Our vapor pressure equation [6] uses the reduced argument,

x(T) = ( 1 -T /T)/ ( 1 -T /T ) , t t c where subscripts t and c refer to triple- and critical points,

2 3 4 £ In (P /P ) = a« x + b* x + c • x + d • x + e • x. ( 1 -x) ( 1

)

and the exponent is e = 1 . 3 for methane [1 5] and for oxygen [ 16] . Originally the term

4 i d-x was absent. It has been added here to improve representation of the ethane data.

The following discoveries are found with the original equation of four terms.

Optimum exponents in the range 1 . 1 < e ^ 1.9 are obtained merely by changing the

sets of data used for least squares. Hence we must rely on the more precise methane

and oxygen data to select e =1.5. Varying the critical-point temperature within

reasonable limits has no significant effect on the overall, rms relative pressure deviation s

.

By examining numerous results we have selected for least squares only the data

of Ziegler at P < 1 atm [ 23], and the data of Pope, Pal [13] and Douslin [24] at P > 1.9 atm.

Whereas the temperature scale of Ziegler may be thermodynamic (the report is not

clear), we nevertheless find that deviations (rms in relative P) are minimized by

converting both sets of data to T-1968 as if they had been on T-1948 [

1 ] . All T used

in the following are T-68.

The triple-point temperature was reviewed by Ziegler et al. Their selection

of 69.89 K becomes 89.899 on the 1968 scale. The critical-point temperature 305.42 K

of Pope has been changed to 305.33 K for consistency with the data of Douslin ( 24] . A

value T = 305.33 r 0.005 K is given by P. Sliwinski, Zeit. Phys. Chem. b_8, 91

( 19'; t) based on analysis of dielectric constants. This was kindly pointed out by

D. E. Diller. We obtain pressures at these end points from the vapor pressure

As additional data may be found, we reserve comment on the deviations of

individual authors, and omit the labor of preparing deviation plots.

Calculated pressures, slopes and curvatures are given at uniform temperatures

by Table 5.

For comparison with functions in our original vapor pressure publication [6],

we give these functions in Table 6, as computed via eq (1) namely

x(T ) 5 (T-T /T ) /( 1 - T / T ),

t t c

Y (P ) s tn(P/P )/tn(P /P ). (2)

These variables range from zero to unity. The equation

Y = x (3)

represents the basic vapor pressure equation

£n(P) = a - b/T (4)

when this is constrained to the end-points (triple and critical). Hence (Y-x) is the

deviation of data from (4).

Finally, we give the computer programs used in this work as a means to check

for errors, and to facilitate resumption of this research.

Addendum. Following work shows that the second virial coefficient used by Ziegler

et al. to obtain vapor pressures is not consistent with our selection. At 200°K his

B(T) = - 455 cc /mol, whereas our B(T) = - 417.5. We therefore have recomputed our apor pressure constants using Ziegler's vapor pressure data from his Table IX for

"Curve B” of his Figure 1, for which B(T) = - 410 cc/mol at 200 K. The difference in

his vapor pressures at 90 K is (7.80-7.33)/7.33 = 6.4 percent, the new values being

the greater. Our new results for eq (1) are given in Table 7, (pages 20, 21) and tables

8 , q on pages 22, 23 of this report. We prefer these constants for future use.

1 SUHJECTEthane Virial Coefficients and Saturated Vapor Densities

NAMB R. D. Goodwin

DATE Aueust 14. 1973

1 . Introduction

The virial equation of state for low densities is needed for thermal computations

to generate P-C-T data, and to obtain saturated vapor densities via the vapor pressure

equation

.

In this report we develop analytical representations for the virial coefficients

of ethane and obtain the corresponding saturated vapor densities.

In the truncated virial equation,

2 3 Z ( T , d ) = P /( R • T • d) = 1 + B(x) • o + C(x).o + D(x)-a , (1)

P is pressure, R the gas constant, T the absolute temperature, d the density, and

a^d/d c is reduced density. The second, third, and fourth coefficients B(x), C(x),

D(x) are dimensionless functions of reduced temperature x =® T/T . We use T

c c s 305.33 K, andV = 1/d = 145.56 cc /mol from Douslin f 2] . In the table s we use

c c symbols B

::

, C' and D'r for the coefficients of (1).

2. The Second Virial Coefficient

Data for B(x) through about I960 are reviewed by Tester [ 16]. Since then we

have data from Gunn [8], Hoover [9], Pope [15], McGlashan [12], and Douslin [2],

Data of Gunn and of Douslin extend from 273 K upwards to 623 K. McGlashan gives

outstanding experimental work on the hydrocarbon series (but not on ethane) down to T/T = 0.5. From his formulations he concludes that the low-temperature data of

c Eucken and Parts [ 4] are wrong. This suspicion also was expressed by Ziegler et

al. [17],

For least squares we have selected for low temperatures only the data from

McGlashan's formula because all other data diverge widely therefrom (Table 2). For

high temperatures we have selected Douslin' s recent data because the experimental

work [ 2J was executed with great care. Table 2 shows that Michels (1D = 3) and Gunn

(1D=8) are in substantial agreement with Douslin. For consistency with Douslin,

we have increased the absolute values of McGlashan's data by one percent, well within

the uncertainty of his V 148 cc/mol.

(10) Douslin. Data not used for l. s . are compared with (2) in Table 2: (1) Eucken;

(2) Lambert; (3) Michels: (4) Hoover; (5) Pope; (8) Gunn.

The Third Virial Coefficient

For C(x) relatively few data are known to us. The data of Michels [13] and

Hoover [9] were generalized in 1967 by Chueh [1], using a formula similar to that developed by Goodwin [5]. In 1971 Pope [15] gave five low-temperature values from 210

to 306 K. For temperatures above 273 K we are fortunate to have the recent, carefullyderived data of Douslin [2].

A comparison of Chueh' s generalized function with Douslin' s data at T/T =2

c shows C =0.20 (Chueh), and C =0.15 (Douslin). Whereas the Chueh formula gives

nearly constant values at high temperatures, the Douslin data are trending asymptotically toward zero.

For least squares we have selected the data of Douslin at high temperature s , and

data generated by Chueh's formula at low temperatures. For consistency we have

diminished these latter values by two percent. (Chueh fails to give his critical densities.

At low temperatures the third virial coefficient is not important in the computation of

sq (1) because the maximum possible density (saturated vapor) is diminishing exponen-

-ry / T

fcially with temperature, e , (see Table 4).

4. The Fourth Virial Coefficient

Recent data of Douslin [2] are plotted in Figure 1. The general behavior expected for D is shown in the book by Mason and Spurling [11]. As present data exist

only at T > T » we use the simple formula, ’ c 100-D ;,: =x • exp^a-b/(x- 1

where x

“ T/T , and a = 4.00, b = 1.84 from Figure 1. c

5. Examination of the Virial Equation

It is valuable to know the relative importance of the terms of eq (1). In Table 4

we compute these for the saturated vapor, using densities from the formula of Plank

and Kambe i tz quoted by Tester [16], We have increased the P.K. den s itie s by 0 . 088%

to agree with the virial equation at 90 K. Pressures are from our vapor pressure

equation [ 7]

.

In the fourth column of Table 4 we give the ratio DI/DN of ideal gas density to

2 the P.K calculated densities. Fifth and sixth columns give B(x).a and C(x).o . If all

data were accurate, we should expect Z(T,d) in the last column to be the same as DI/DN.

The vapor pressures of Ziegler [17] were based on second virial coefficients

of Eucken and Parts [4], the accuracy of which Ziegler questioned. Our selection for

B

:|: also disagrees with Eucken and Parts. We therefore have recomputed our vapor

pressure constants using alternate vapor pressure data of Ziegler, as shown in the

addendum to our Laboratory Note [7], This revised vapor pressure equation is used

in the following to obtain the densities of saturated vapor.

6, Derivation of the Saturated Vapor Densities

For a given temperature we iterate density in the virial equation to obtain a pressure therefrom which is the same as the vapor pressure. Results are in Table 5.

In previous work we have found that this method gives acceptable results at densities

up to about D / 3 , which for ethane occurs near T = 286 K. We see that data from the

c Plank-Kambeitz formula diverge increasingly from our results on approach to T . c The highest temperature at which our results are accurate remains to be seen by comparison with data from other sources. Figure 2 shows ,howeve r , that in the region of

overlap with Douslin's vapor densities [2], our results (the filled circles) appear

reasonable

.

Figure 8 shows the results at lower temperatures. We see that powers of

(1/T) greater U an the first will be needed to describe these data.

7. Discussion of Uncertainties

Experimental uncertainties for virial coefficients vary inversely as the significance of these coefficients in giving departure from ideal gas behavior, see Table 4.

For the second coefficient only, for example,

6B/B 6 Z _ Z

Z

’ Z-l ’

where 6B and 6Z are small variations in B and Z. Assume a tolerable error of 0.0 1 percent in Z. From Table 4 we compute the approximate tolerable uncertainty in B,

neglecting the effect of C(T),

and we believe these to be reasonable estimates for very careful work. In Table 2,

however, we see that Hoover's data, ID=4, differ from our selection by up to five percent at low temperatures (215 and 240 K).

Our derived densities depend on the vapor pressure equation. This we estimate

to be uncertain by several percent at the lowest temperatures approaching the triple

point. The virial equation, on the other hand, approaches ideal gas behavior at these

low temperatures. At the higher temperatures above 270 K, we believe the virial coefficients and vapor pressures of Douslin to be accurate as can be derived from the best

of PVT measurements.

SUBJECT The Orthobaric Densities of Ethane, Methane, Oxygen and

Fluorine

NAME R . D. Goodwin

DATE Sept. 18, 1973

1 . Introduction.

These densities, and accurate analytical descriptions thereof, are essential

for the computation of thermodynamic functions, in particular to obtain heats of

vaporization via the Clapeyron equation, and to formulate the equation of state which

originates on this locus [4].

We have had difficulties in representing the available ethane data, and therefore have returned to fundamentals. For comparison we shall include oxyge n [18],

fluorine [13], and methane [4]. Previous formulations occur in [4, 7], We start with

the saturated liquid densities because their representation is much simpler than that

of the saturated vapor densities.

2. The Saturated Liquids.

It is well known that these densities are described near the critical point by the

form

p = p + a • (T - T) + b • (T - T)

e (1)

c c c

wherein the first two terms are the rectilinear diameter, and the exponent is near

s =0.35.

Let us constrain (1) at the boundaries by use of the variables,

x ( T ) = ( T - T)/(T - T ), (2) c c t W(p) = (p - p etc )/(p - p ), (3)

where subscripts c and t refer to critical and triple points. Equation (1) now

become s

,

W(p)=a*x + b*x", (4)

and the constraint requires that a + b = 1. If we solve this for the constant b, we may

expect to obtain a function Y(p,x) which is nearly constant over the entire range

0 < x < 1,

Y(p , x) = [W(p) - x]/(x

£

- x). (5)

This sensitive function is useful for examining data.

In past work we found that three arbitrary coefficients are required to describe

saturated liquid densities. We now find the following results via many exploratory

computations. For the smoothed data used here for oxygen and fluorine, the use of

five arbitrary coefficients gives an improvement in the "fit". For the rough experimental data used here for methane and ethane, the use of five arbitrary coefficients

gives virtually no improvement in the "fit" as compared with only three coefficients.

With only three, the first equation used was,

ethane. After much exploration we have selected the following representation,

• x (7)

Table 1 gives the fixed-point constants. Table 2A gives the exponent e found

by trial, the least- square s coefficients, the rms of relative density deviations in

percent, and the number of datum pairs, NP.

Tables 3, 4, 5, 6 compare calculated with experimental densities. No

temperature- scale adjustments have been made in present work. Column YX gives

the experimental value of Y(p,x) via (5), whereas column YC gives the value calculated

by the right side of (7). Table 7 compares ethane data not used for least squares.

Tables 8, 9, 10, 11 give saturated liquid densities computed by (7) at uniform

temperatures, and also their slopes and curvatures.

The small deviations for oxygen and fluorine necessarily are systematic because the data were smoothed by the authors. The overall methane deviation is large

because experimental data from various sources are included in the critical region.

The low-tempe rature ethane data of Miller were used to estimate the triplepoint liquid density. Other data are from Canfield et al. , and from Klosek/McKinley

.

The high -tempe rature "data" of Eubank are a correlation of available experimental

data down to the boiling point 184.5 K, (x = 0.561). We estimate uncertainty in our

calculation of these densities to be about 0. 1 percent over the entire range.

Concerning assignment of critical densities, we at first found both P c and

exponent € simultaneously by trial to minimize the overall deviation. The results are rough because these two parameters are mutually compensating for data in the critical

region. Hence we have adjusted P c one step at a time for both saturated liquid and

saturated vapor, examining the values of e found by trial. We select that value of p c which yields reasonable exponents £ for both liquid and vapor. For methane it thus

is necessary to select P c

= 10. 2 mol/T, at the upper limit of uncertainty in the experimental values [4],

3. The Saturated Vapors

Densities of the ethane vapors range thru a factor of about 10^. We have given

reasons for using the logarithm of vapor densities, with arguments in powers of

(1/T), [7]. Define the normalized variables

For the present work we have explored all kinds of representations, finally

selecting the expression,

5 Y(p , z) = A

1 + ^

A. • z l/3

. (12)

Table 2B gives results for (12), analagous to table 2A for the liquid. Tables

12, 13, 14, 15 compare calculated with experimental vapor densities. Column YX is

the experimental value of Y(p,z) via (11), whereas YC is calculated by the right side

of (12). Table 16 compares ethane data not used for least squares. Tables 17, 18, 19

20 give uniformly computed densities and derivatives via (12).

Computer programs used in this work are attached as an appendix.

SUBJECT Liquid-Vapor Saturation (Orthobaric) Temperatures of

Ethane and Meth£ne_

name

£). Goodwin

DATE Nov. 28, 1973

1. Introduction . The present, new investigation has been necessary to accommodate the

extreme range of ethane saturated vapor densities (a factor of 10

7

). Our previous

work on ethane appears in Lab. Notes 73-2,3,4,5.

Analytical description of the two-phase, liquid-vapor equilibrium (temperature-density relationship) is needed for our new equation of state which originates on this locus (NBS IR 73-342). In particular, the forms used below give the important

property that all derivatives are zero at the critical point.

In the following we split the range, using different functions according

P ^ P c . In each case the dependent variable is

Y(T) = (Tc /T-1)/(TC /Tt -1) (1)

The symbols used here appear in a LIST.

2. The Saturated Vapor Temperatures . The analytical formulation is

Y(T) = U (t

)

. [1 + Ao • In (a /ct

6 ) + W(a )] where

U(a) ~ exp[a . (ug - u)],

and n

W('-r) -

l

At • (q

1 - cp5 ).

i = 1

1/3 1 / 3 The notation is q

o'

, q^ 0g , and Ug 1 / 1 crg - l j .

This equation is constrained at the vapor triple point.

Fixed-point constants are given by table 1, and coefficients by table 2. The comparisons of results for ethane and for methane are in tables 3,5. Deviations

necessarily are systematic because the "data" are smoothed analytically (Lab. Note

73-5). We believe all deviations to be well within the real accuracy of the data.

3. The Saturated Liquid Temperatures.

The analytical formulation is

f.n(Y) = 8 •

Table 12. Experimental and calculated P-p-T data

The following pages compare experimental P-p-T (compressibility)

data with densities and pressures computed by the equation of state (5).

The first column identifies sources of the data (as in Table 10):

ID Authors

2 Virial equation (4).

8 Reamer et al [57].

9 Michels et al [47].

10

Douslin and Harrison [14].

100+ A. K. Pal, via Pope [54].

The equation of state was adjusted only to data of ID = 2, 9, 10,

and 1300+

. Remaining data validate our extrapolation to higher pressures. Density deviations should be ignored near the critical point,

and pressure deviations should be ignored for compressed liquid at

low temperatures for reasons given in the text.

Table 18. Calculated P(p) critical isotherm

The following page gives a high-resolution examination of the

critical isotherm of ethane as computed by equation of state (5). Column

headings have the following interpretations -

D/DC = d/dc , density reduced at the critical point.

P/PC = P/Pc , pressure reduced at the critical point.

DP/DD = c'P/cid, slope of the critical isotherm, bar/(mol/X).

The last five columns give the density-dependence of functions

used in the equation of state, where R = p = d/d^ is density reduced at the liquid triple point-

DTS/DR = dT a

(p)/dp, K.

DTH/DR = d0(p)/dp, K.

DPS/DR = dPr7 (p)/dp, bar.

DXB/DR = B$(p, T)/9p.

DXC/DR h 3Y( P , T) /Bp.

Table 23. Calculated P(T) isochores

The following pages give P(T) along isochores, as computed by

the equation of state. The third column DP/DD is the isotherm slope

(ciP/Bp) in units of the bar and mol/X. The last two columns give the

2 2

isochore slopes and curvatures cP /BT, S P/dT , in units of the

bar and K.

These tables show that the isochore curvatures are qualitatively

consistent with a maximum in the specific heat C v

(p, T) at the critical

point.

Table 24. Calculated P(o) isotherms

The following pages give P(p) isotherms, as computed by

the equation of state (5). The third column DP/DD is the isotherm slope

(3P/Bp) in units of the bar and mol/j£. The last two columns give the

isochore slopes and curvatures, DP/DT = (3P/3T), D2P/DT2 =

2 . 2

(B P/BT ) in units of the bar and Kelvins.

These tables show that 3P/Bp is non-negative, and that it increases

monotonically with density to pressures about twice those for adjusting

the equation of state.

Table 26. Thermophysical properties of the saturated liquid

This table was computed by integrating first along isotherm

of Figure 9> then along isobar P^, and finally along each isotherm down to the saturated liquid boundary <> Column headings have the following interpretations --

DPS/DT = dP^ /dT, vapor pressure,

DDL/DT = dp^/dT, saturated liquid,

DP/DT = (dP/ST), single phase,

DP/DD = (dP/6p), single phase,

Q, VAP = AH , heat of vaporization

vap

CV C (P , T)

V

CS = C (T)

cr CP = C (P , T)

P

W = speed of sound

Table 27. Thermophysical properties along isobars

The following pages give physical and thermodynamic properties

along selected isobars, as computed by methods of section 3 of the

text.

The first line of each table refers to freezing liquid on the P(T)

melting line.

Each table P<PC contains a blank line for the transition from

saturated liquid to vapor, as seen by the abrupt decrease of density.

Table headings for partial derivatives have the following interpretations - - DP/DT s dP/6 T,

DP/DD = d P /d p . The specific heat interpretations are -

CV = C (P , T), v CP - C (P , T)

.

P

*These tables are extrapolated beyond the range of P-p-T data used for

adjusting the equation of state (P~350 bar).

15. SUPPLEMENTARY NOTES

16. ABSTRACT (A 200-word or less (actual summary of most significant information. If document includes a significant

bibliography or literature survey, mention it here.) Thermophysical properties are tabulated at uniform temperatures over the entire

range of fluid states from 90 to 600 K along isobars to 700 bar. A new, rational

equation of state is employed for the first time. Thermodynamic functions in the

compressed liquid at T < T are obtained by use of specific heats C (T) along a high

pressure isobar. P

17. KEY WORDS (six to twelve entries; alphabetical order; capitalize only the first letter of the first key word unless a proper name; separated by semicolons) Densities; enthalpies, entropies; equation of state; internal

energies; isobars; isochores; isotherms; Joule -Thomson inversion; latent heats of

vaporization; melting line; orthobaric densities; specific heats; speeds of sound;

vapor pressures.
