A thermodynamic property formulation for ethyl ene^ developed as a part of a joint industry-government project, is presented. The

formulation includes an equation of state, vapor pressure equation, and

equation for the ideal gas heat capacity. The coefficients were determined by a least squares fit of selected experimental data.

Comparisons of property values calculated using the equation of state

with measured values are given. The equation of state is not valid in

the critical region (p^ + 0.3 p^ for temperatures of T^ + 0.05 T^)

.

Errors on the order of 20 percent for derived properties and 10 percent

for density may be encountered near the critical point. Tables of the

thermodynamic properties of ethylene for the liquid and vapor phases for

temperatures from the freezing line to 450 K with pressures to 40 MPa

are presented. The equation of state and its derivative and integral

functions for calculating thermodynamic properties are included.

Estimates of the accuracy of calculated properties are given. A guide

for use of computer programs for the calculation of thermodynamic

properties of ethylene with listings of subprograms and a sample program

to illustrate the use and results of the program are included.

Key words: Computer programs; equation of state; ethylene; thermodynamic

properties; tabular values.

1 . Introduction

Six years ago a group of Petrochemical companies and the National Bureau of

Standards embarked on a joint industry-government project to determine the

thermodynamic properties of ethylene. The first four years of the project were

devoted to experimental work, which provided data for the development of a

^ This work was a joint Industry-Government project under the sponsorship of

Celanese Chemical Company, Cities Service Oil Company, Continental Oil Company,

Gulf Research and Development, Mobil Chemical Company, Monsanto Polymers and

Petrochemicals Company, Phillips Chemical Company, Union Carbide Corp. and the

National Bureau of Standards,

Thermophysical Properties Division. Permanent affiliation is the Center for

Applied Thermodynamic Studies, University of Idaho, Moscow, Idaho 83843.
mathematical model for the thermodynamic properties of ethylene. The fifth and

final year of the project was spent developing the model.

One of two resulting equations of state for ethylene is presented here for

the range of liquid and vapor states for temperatures from the triple-point

temperature to 450 K, with pressures to 40 MPa. The second equation of state is

for the critical region and appears elsewhere (Hastings, et al . [14]). With a few exceptions, the equation of state presented here represents the selected

experimental P-p-T data to within the estimated accuracies of these data.

Comparisons to various experimental values of other thermodynamic properties

indicate some discrepancies between those experimental data and values calculated

using the equation of state. These discrepancies, which are discussed in

sections 8 and 9, are particularly evident in the critical region, though some irreconcilable discrepancies are found outside of the critical region. The

equation of state given here is not valid in the critical region (p + 0.3 p for temperatures of T + 0.05 T ).

The equation of state may be used for the calculation of accurate tables of

thermodynamic properties of ethylene within the range of its applicability. This

equation may also be readily adapted to systems analysis work where iterative

solutions are required to solve the equation for known variable pairs other than

density and temperature. A table of thermodynamic properties of ethylene for the

range of applicability of the formulation is included here.

In determining the equation of state for ethylene, considerable experimentation in the use of various least squares methods and different functional forms

was conducted. Also, experimentation in the use of different groupings of the

independent data sets used in determining the equation of state led to the

selection of several data sets for use in the least squares determination of the

final coefficients.

In addition to the equation of state, the ancillary functions required for

the calculation of thermodynamic properties are given. These include a vapor

pressure equation, an equation for the ideal gas heat capacity, and equations for

the density of the saturated liquid and saturated vapor.

A summary of the available data for ethylene is given, and the ranges of

these data are tabulated. Comparisons of these measured, data to values

calculated from the equation of state have been made to establish the accuracy of

the equation of state in representing P-p-T values and other thermodynamic

properties. These comparisons have been divided into two groups. The first
group includes those data which were used in the fit and the second group

consists of all the data sets that were knov/n to the authors, including those

used in the fit. The comparisons to data used in the fit are an indication of

the success of the model in representing the data selected for the least squares

process, while the comparisons to all data provide information about the relative

agreement of data sets from different sources. The latter comparisons are included in Appendix A.

The thermodynamic properties reported here have been calculated using the

equation of state and derivative relations among the thermodynamic properties.

Since the equation of state has been developed to conform to the Maxwell

criterion for phase equilibrium, properties of the liquid may be calculated by

continuous integration of the equation of state through the two-phase (liquidvapor) region of the surface. The liquid-vapor coexistence properties included

in the tables have been calculated using the vapor pressure equation to establish

the saturation temperature for each specified pressure.

No estimate of the accuracy of this formulation for the region near the

critical point is presented here. Since analytic equations of state must fail at

the critical point in the representation of anomalous behavior of certain

properties, the user of this work is advised that this formulation should not be

used within about 5 percent of the critical temperature and 30 percent of the

critical density. The recent work of Hastings, et al . [14] should be used to

calculate thermodynamic properties of ethylene within the near-critical region.

The formulation of Hastings, et al. [14] includes a scaled fundamental equation

using revised and extended scaling techniques that is accurate in the

-4

representation of critical region data to within 5 x 10 Kin temperature,

_5

5 X 10 MPa in pressure, and 0.03 percent in density. The critical point

values of P-p-T used here are taken from Hastings, et al . [14].

Much of the experimental data used in the development of the equation of

state for ethylene has been measured as a part of the joint industry-government

ethylene project under the direction of the National Bureau of Standards, Office

of Standard Reference Data. The availability of high quality measurements of the

thermodynamic properties of ethylene has provided excellent definition of the

surface of state, and has uncovered some problems of scientific interest in the

representation of this surface by present modeling techniques. Further studies

of the modeling of the surface of state of fluids of engineering interest may
well make use of the data for ethylene in efforts to improve the representation

of data near saturation and in the critical region.

2. Experimental Measurements of the Thermodynamic Properties of Ethylene

2.1 Pressure-Density-Temperature Data

The experimental P-p-T data sets for ethylene are listed in table 1. The

data for the liquid and vapor states of ethylene form a comprehensive network of

values to represent the surface. The distribution of these data is shown in

figure 1. For clarity, this figure includes only 2331 data points from the total

of 2706 points listed in table 1. The data omitted are near the critical point.

In instances where there are two or more papers by the same principal author, the

symbols used in the data map represent data by that author from more than one reference.

2.2 Coexistence Properties

Recent measurements of the vapor pressure of ethylene are reported in

Douslin and Harrison [6], Straty [33], Bigeleisen, et al . [3], Egan and Kemp [8],

Hastings and Levelt-Sengers [13], Michels and Wassenaar [26], Tickner and

Lossing [39], and Gammon [9]. Measurements of the orthobaric densities of

ethylene are reported in Hastings, et al . [14], Golovskii and Tsymarnyi [10],

Menes, et al . [24], and Haynes [15].

2.3 Calorimetric Data

Measurements of the isochoric heat capacity of ethylene for eight isochores

have been made by Weber [47]. Nominal densities of these isochores are 4.6, 5.9,

6.7, 11.8, 15.6, 17.8, 21.6 and 20.0 mol/dm^. Values of C have been derived

from velocity of sound measurements by Gammon [9]. Isobaric heat capacity values

for ethylene are reported by Vaschenko [42], by Hejmadi and Powers [16], and by

Watanabe [45]. The C^ data of Weber [47] and Gammon [9] and the C data of

Vaschenko [42], Hejmadi and Powers [16], and Watanabe [45] are illustrated in

figure 2. Four C^ data points of Watanabe [45] and one C data point of

p p

"^ Vaschenko [42] are for pressures below the scale of figure 2 and are not included

in the figure. Selected values of the Cy data of Weber [47] were included in

the data set used for determining the equation of state. However, these data were used in this work primarily to provide an indication of the reliability of

values of C and C calculated using the equation of state and the ideal gas

heat capacity equation.

2.4 Velocity of Sound Measurements

The velocity of sound of ethylene has been measured extensively. The 753

data points of Dregulyas and Stavtzev [7], Gammon [9], Soldatenko and

Dregulyas [32], Terres, et al . [35], Mehl [23], and Herget [17] cover the surface

of state as shown in figure 3. Five data points of Gammon [9] on the saturated

liquid line are for pressures below the scale of figure 3 and are not shown on the figure. These data were not used in the fitting of the coefficients, except

as noted below, but were used to provide confirmation of the accuracy of the

resulting equation of state for the calculation of velocity of sound for both

liquid and vapor states. Table 2 summarizes the recent velocity of sound data

for ethylene.

convenience of the reader. Temperatures in the table are given on the

International Practical Temperature Scale of 1968. There is good agreement among

the results of the three independent experiments. The values below 235 K were

obtained by the authors by means of a simultaneous fit of Douslin and

Harrison [6], Waxman [46] and the velocity of sound data by Gammon [9]. These

values were not used in the fit of the final equation of state [eq (1)] but were

used to determine saturated vapor densities at temperatures below 235 K.

3. Weighting of the Data

Each data point used in the least squares determination of the coefficients

of the equation of state was assigned a weighting factor based upon estimates of

uncertainties of the variables reported by the experimenter. In most cases these

estimated uncertainties were taken from assessments of the overall accuracy of

the data sets. Where reliable estimates of uncertainties were not available,

estimated accuracies were determined by comparison to preliminary least squares

representations of the surface. The weights used in the fitting process were calculated using approximating functions and the error propagation formula. In

several instances, the error propagation weights were modified by the assignment

of arbitrary multiplicative factors to increase or lessen the effect of a particular data set on the overall representation of the surface.

4. The Determination of the Equation of State

4.1 Analysis of the Functional Form of the Equation of State

Several functional representations were suggested as possible forms for the

equation of state for ethylene. Among these are a 32-term modified BenedictWebb-Rubin (BWR) equation originally proposed in Jacobsen [18], and four other

forms which utilize stepwise regression methods to select individual terms from

an initial comprehensive function containing a large number (50 to 80) of

possible terms. These four forms include an 80-term modified BWR equation, two

50-term modified BWR equations (one using reduced coordinates and the other a dimensional form), and a 51-term fundamental equation which has been used

successfully for other fluids (Jacobsen, et al . [19] and Mui, et al . [29]). For

the ethylene data set described in this work, no clear preference for one of

these forms over the others could be established on the basis of the quality of

the fit of the data, and it was decided to use the pressure explicit dimensional

11
BWR equation proposed in Jacobsen [18] to represent the data for ethylene

excluding a wide range of values near the critical point. This equation form is

v/idely used for other fluids and has been shov/n to exhibit correct thermodynamic

behavior for .Tiuch of the surface of state. The equation form is given as eq (1) .

4.2 The Selection of Data for Mul tiproperty Fitting

This equation of state for ethylene was determined using experimental

thermodynamic data including selected P-p-T, C , C , velocity of sound data,

and data to define saturation states to satisfy the Maxwell criterion for phase

equilibrium. The P-p-T data selected for use in the least squares fitting

process are illustrated in figure 4. The C data of Weber [47] used in the

least squares fit were 7 points on the 11.8 mol/dm isochore, 13 points at

The nonlinear coefficient, y = 0.0172, in each exponential term was specified prior to the determination of the linear coefficients.

15.6 mol/dm and 4 points at 19.9 mol/dm . The velocity of sound data used

in determining the equation of state data are illustrated in figure 5.

The multi property fitting procedures used 'nere suggest the existence of

systematic inconsistencies among the various data. The data sets which were not

used in determining the final constants are those which seemed to exacerbate the

problem of overall consistency. However, the authors were unable to determine

the exact nature of the inconsistencies, and no conclusion as to probable or possible systematic errors within any given data set can be inferred from this

work. Although the data near the critical point were excluded from the selected

set, the critical point of the equation of state was constrained to the values

T^ = 282.3428 K, P^ = 5.0403 MPa, and p^ = 7.5340 mol/dm"^. A later value of

the critical temperature given in [14] is 282.3452 K. The equation of state for

ethylene reported here, eq (1) with coefficients from table 4, has been compared

to selected data sets to illustrate its accuracy. These comparisons are presented in section 8 and 9. Coefficients for the equation of state (1) for

ethylene are given in table 4.

5. Liquid-Vapor and Liquid-Solid Coexistence

5.1 Liquid-Vapor Coexistence

The most difficult part of the fluid surface to model mathematically is that

defining the liquid-vapor coexistence conditions. Even excluding the critical

region, T = T + .05 T and p = p + .3 p , where the equation of state is not

valid, the rest of the two phase boundary is subject to errors in representation

which may be most obvious in the derivative properties at saturation, i.e.,

C , C , and velocity of sound,

v pThe procedure used here v/as to first obtain equations for the vapor

pressure, the saturated vapor density, and the saturated liquid density as functions of saturation temperature. These equations, together with the

condition of equality of Gibbs free energy for the coexisting liquid and vapor

phases, were then used as input data in the least squares fit of the equation of

state.

Recent vapor pressure data for ethylene are summarized in table 5. The

vapor pressure equation for ethylene has been determined using the data of

Gammon [9], Straty [33], Hastings and Levelt Sengers [13], Douslin and

Harrison [5], and Bigeleisen, et al . [3]. The equation used in this work is

The table of saturation properties in Appendix 3 was calculated by specifying T and then solving the vapor pressure equation, (2), for the saturation

pressure. Using the P-T coordinates of a vapor pressure point, the equation of

state (1) was then solved for the density of the saturated liquid and vapor using

an appropriate iterative procedure. Figure 6 illustrates the agreement between

the densities calculated in the above manner and corresponding values from

various sources.

An alternative method of calculating the saturation properties is to solve

the equation of state for the thermodynamic conditions for coexisting phases,

i.e., equal Gibbs free energy for constant P and T. This calculation is

accomplished by equating Gibbs free energy of the liquid to the Gibbs free energy

of the vapor and the pressure of the liquid equal to the pressure of the vapor at

a common temperature. This results in two equations in two unknows, i.e.,

density of the vapor and density of the liquid. As a matter of interest this

calculation was done for the equation of state reported here and the results are shown in table 9.

5.2 Liquid-Solid Coexistence

equation is

6. The Ideal Gas Heat Capacity Equation

The ideal gas isobaric heat capacity values from Angus, et al . [1] for

temperatures from 100 to 500 K have been represented by an equation suggested by

Barieau [2].

Cp/R = N^/T^ + W^n'^ + N3/T + N4 + N5T + NgT^ + N^T^ + NgU V/(e"-l )^, (6)

where C is the ideal gas heat capacity, T is the temperature in kelvins, and

u = Ng/T. The coefficients of eq (6) for temperatures in kelvins are given

in table 10.

Cp(T,p) = C^(T,p) + [(T/p2)OP/3T)^/OP/8p)^] . (11)

The velocity of sound is calculated from the relation,

W(T,p) = [(Cp/C^) OP/3p)^]^/2 . (12)

The representations for the properties are continuously integrated through the

two-phase region to define states in the liquid range. This was made possible by

25
the fitting procedures employed in the development of the equation of state in

which the conditions for two-phase equilibrium were included in the least squares

determination of the coefficients for the equation of state. A table of

properties of ethylene is included in Appendix B.

8. Comparisons of the Equation of State to P-p-T Data

Comparisons of values of density calculated using the equation of state with

experimental densities used in determining the coefficients of eq (1) are included in the graphs of figure 8. Calculated density deviations for

thirty-nine of the selected data points of Douslin and Harrison [6] and six data

points of Hastings, et al. [14] exceeded the scale of figure 8. Thirty-four of

these points of Douslin and Harrison and all of the points of Hastings are in the

critical region (within + 30 percent of the critical density and within + 5 percent of the critical temperature). Comparisons to all P-p-T data including

those data not used in the determination of the equation of state are given in

Appendix A. The critical region is outside the range of this formulation;

however to illustrate the actual behavior of the formulation in the critical

region, comparisons with critical region data are included in Appendix A.

9. Comparisons of the Equation of State With Related Thermodynamic Data

Although only selected thermodynamic data together with the P-p-T data were

used in determining the equation of state, comparisons to these data as well as other derived property data are given here to indicate the accuracy of the

equation of state in representing these related properties. Figure 9 includes

1 f) comparisons with the C data of Weber [47] and with values from Gammon [9].

Table A-2 includes values of C which exhibit deviations larger than the scale

of fi gure 9.

Comparisons to the velocity of sound data used in determining the equation

of state are illustrated in figure 10. Five data points of Dregulyas [7] have

deviations beyond the scale of figure 10 ranging from -1.1 to -3.8 percent.

Thirteen data points of Gammon [9] have absolute deviations from 1.1 to 1.7

percent, and are also excluded from figure 10. Figure 11 is a comparison to the

Data taken as a part of this project.

data of Gammon [9] for the velocity of sound of the saturated liquid used in the

fit of the equation of state. Four data points between temperatures of 280 K and

282.15 K were excluded from the fit, and one point near 260 K has a deviation

exceeding one percent and is not shown in figure 11. Comparisons to all

available single phase velocity of sound data are given in Appendix A. Using

saturated vapor states determined by extrapolation of the equation of state to

the vapor pressure has resulted in some improvement in the comparison to the

saturated liquid velocity of sound values of Gammon over saturation values

determined by other methods. The resulting improvements did not significantly

alter the P-p-T representation of this formulation from that of preliminary fits

of the P-p-T data alone, and the final values of saturation densities are generally within the estimated accuracy of the measured data of Golovskii and

Tsymarnyi [10] and Haynes [15]. These comparisons indicate large discrepancies

between the data and values of the velocity of sound calculated from this

formulation at and near saturation above 230 K in both liquid and vapor states.

The values calculated using this formulation in this region must be considered

unreliable.

Figure 12 shows comparisons between the experimental C data by Hejmadi

16

"^ and Powers [16] by Watanabe [45], and by Vashchenko [43] and corresponding

calculated values from eq (1). Data points with deviations beyond the scale of

figure 12 are also included in table A-2 in Appendix A.

Table 11 gives a comparison among the heats of vaporization calculated using

the eq (1), those of Douslin [6], and the data of Kozlov [20]. Other heat of

vaporization data, Douslin [6], Egan and Kemp [8], Clusius and Konnertz [5], and

Tully and Edmister [41], are included for comparative purposes.

The data from Kozlov [20] are a result of a cooperative effort between this

project and the Data Center of the State Service of Standard Reference Data for

Organic Compounds at Kiev in the USSR. This project furnished the laboratory in

Kiev with an ultra-pure sample of ethylene; in return, the Kiev laboratory

agreed to make heat of vaporization measurements and velocity of sound

measurements on that sample and furnish the project with the results prior to

their publication. Both the heats of vaporization and velocity of sound data

have been received from the USSR. As shown in table 11, the heats of

vaporization from Kozlov [20] do not agree with the present correlation and are believed to be incorrect. These heats of vaporization were not used in the fit

of eq (1). The velocity of sound data of Dregulyas and Stavtzev [7] are in good

agreement with those of Gammon [9] and proved to be of considerable value in the

correlation as they provided information in the compressed liquid region where no other velocity of sound measurements exist. The velocity of sound data of

Dregulyas and Stavtzev [7] were used in the fit of eq (1).

10. Estimated Accuracy of the Equation of State

The equation of state presented here may be used to calculate properties of

ethylene for liquid and vapor states from the triple point temperature to 450 K with pressures to 40 MPa. Based upon the deviations of calculated values from

data values, the accuracy of the equation of state is estimated as + 0.20 percent

in density for most of both liquid and vapor regions of the surface. At the

highest temperatures, i.e., above 400 K, the uncertainty is estimated as + 0.3

percent in density. The equation is not valid near the critical point and should

not be used for states within 30 percent of the critical density at temperatures

within 5 percent of the critical temperature. The formulation should be

considered accurate to within + 2.5 percent for the calculation of heat capacity

values, and within about + 1 percent for the calculation of velocity of sound

except in the critical region, and at (and near) the saturated liquid and

saturated vapor states where the deviations may be larger. A possible additional source of error when calculating thermodynamic properties using any equation of

state, no matter how accurate that equation of state might be, is the error resulting from errors in the input variables. This error is especially important

in the case of custody transfer when the equation of state together with a measured pressure and temperature is used as a means of determining the total mass. Figure 13, reproduced from Thomas, et al. [37], illustrates the resulting

errors in density due to errors in the input pressure and temperature. The chart

has been constructed for an assumed error in measurement of temperature of 0.5 K and an assumed error in pressure of 0.5 percent. Except for the liquid region

where the errors in density are almost entirely the result of the assumed error

in temperature, the resulting error in density as shown in figure 13, is divided

about equally between the assumed errors in pressure and temperature. The chart

may be used for other assumed errors in pressure and temperature by a linear

11. Conclusion

At the beginning of this project, the goal was to provide a mathematical

model of the thermodynamic surface of ethylene and new property tables more accurate than those of prior formulations. It was expected that these results

would be accurate to within J^ 0.1 percent in density and within + 1 percent in

derived properties such as C . In addition to the general accuracy statement

above, the model was to include the critical region by using a switching function

as the critical region is encountered. This would accomplish the merger of the

critical region model of Hastings, et al . °[14] with this formulation. The merger

of the two equations was not accomplished and the reader who wishes to make

calculations in the critical region (p +^ .3 p for temperature of T +_ .05 T ) should use the equation of state in Hastings, et al . [14],

Although a substantial improvement has been made over the equations and

tables available six years ago, the accuracy goal has probably not been achieved.

Unfortunately the two major sets of P-p-T data used in the development of the

model, i.e., Straty [33] and Douslin and Harrison [6], disagree by as much as 0.2

percent in regions common to the two data sets. A good deal of effort, including

additional experimental work and alternate methods of data analysis, was expended

43
in trying to resolve this disagreement without success. At the start of this

work, the discrepancy between the two data sets was as large as 0.25 percent.

This disagreement was resolved in part by Straty when he verified that some adsorption had taken place in his early experiments. He built a new cell, and

repeated the experiment. The data from the second experiment agreed more closely

with those of Douslin and Harrison [6], but a 0.2 percent disagreement persists.

Impurities do not seem to be a possible cause of the discrepancy as ultra-pure

samples v/ere used in both Straty 's and Douslin's experiments. Straty repeated

some of his experiments with ethylene which had substantial amounts of known

impurities, with yery little change in the results.

A similar situation exists in the C data of Weber [47], but in this case the disagreement is in a single source. There are apparent inconsistencies among

the various isochores. As a consequence, only a portion of the data were used in

determining the coefficients for the equation of state as outlined in section 4.

In view of the above mentioned discrepancies, and others, it was decided

that until these discrepancies are resolved either by experimentation or by

additional data analysis, further work on the development of the equation of

state is not warranted. Any improvements in the model using the available data

would require new methods of correlation or new techniques of data analysis.

APPENDIX C. Guide for Use of Computer Programs for the Calculation

of Thermodynamic Properties of Ethylene

This guide contains documentation of computer programs for the calculation

of thermodynamic properties of ethylene from the triple point temperature to

450 K with pressures to 40 MPa. These programs are based upon the formulation

given in this document. Methods of property calculation used in these programs

are discussed, and input and output arguments for each subprogram are given.

Program listings for the calculation of isochoric heat capacity (Cy),

isoboric heat capacity (Cp), internal energy (U), enthalpy (H), and entropy

(S) are given in section 3.6. Subprograms for the calculation of ideal gas

properties, vapor pressure, saturated liquid and vapor densities, melting

pressure, and other ancillary quantities are also given.

1. Introduction

This package of subprograms was developed for use on a CDC-6600 scientific

computer for the calculation of the thermodynamic properties of fluids for which

the formulation is based upon the equation of state given in section 4.

Although this guide is specifically for use in calculating the thermodynamic

properties of ethylene with the formulation of this work, it may be adapted for

use in calculating properties of other fluids by making appropriate changes in

the subprograms which define the coefficients for the equation of state and

ancillary equations. These subprograms may also be modified for use with other

pressure explicit equations of state by replacing the routines which define the

pressure and the necessary derivatives and integrals.

This package requires that the equation of state used in the formulation be

developed to satisfy the Maxwell criterion for phase equilibrium to allow

continuous integration along isotherms through the two-phase region. Calculation

of liquid properties using an equation of state which does not satisfy this

criterion requires the use of the Clapeyron relation with the vapor pressure

equation in addition to the methods described here.

The unit system employed in the equation of state for which this package has

3 been developed requires input and output in kelvins, MPa, and mol/dm for the

primary arguments temperature, pressure, and density, respectively. Units for

derived properties are given in section 3.

2. Methods of Property Calculation

The methods of property calculation described here require the following

information.

1. An equation of state

P = P (P,T) , (C-1)

2. A vapor pressure equation for liquid-vapor coexistence states

P = P (T) , (C-2)

3. An ideal gas heat capacity equation

C° = C° (T) . (C-3)

' A thermodynamic formulation is the set of equations used to calculate

properties including the equation of state, vapor pressure equation, and other

ancillary equations.

130
4. The reference properties of the ideal gas,

a. S° the ideal gas entropy at temperature T , and .101325 MPa

b. H-p , the ideal gas enthalpy at temperature T ,

c. T , the reference temperature for a and b.

The values used for S^ , H-r , and T are given in section 7 T« T„' ^

The equation of state for ethylene was developed to satisfy the Maxwell

criterion, so that continuous integration of functions for various properties

through the two-phase region is appropriate. The vapor pressure equation is used

to calculate the saturation pressure or temperature to define the boundary of the

two-phase region.

Equations (7, 8, 9, 10, 11, and 12 in section 7) are used for both the vapor

and liquid phases for the calculation of entropy, enthalpy, internal energy,

specific heat at constant volume, Cy, and specific heat at constant pressure,

Cp, and the velocity of sound, W.

3. Description and Use of Subprograms

A complete listing of all subprograms used for the calculation of the

thermodynamic properties of ethylene is given in section 3.7 of this guide. If

these subprograms are to be used on a computer with a word length less than 11 significant figures it is necessary that all real variables be converted to

double precision and that all functions return double precision values.

The units employed for various quantities in the following routines are: Temperature--kel vi ns Pressure--megapascal

Density--mole/deci meter cubed

Enthal py—joul es/mol e Internal Energy--joules/mole

Entropy--j oul es/mol e-kelvin

Specific Heat at Constant Pressure--joules/mole-kelvin

Specific Heat at Constant Volume--joules/mole-kelvin

Sonic Velocity--meters/second

131
For input and output arguments in other units, the user must modify the

calling program to accommodate the desired units.

The use of the various subprograms in this package is summarized in the

subsections below. The groupings of subprograms and entries for the purposes of

this section are: A. Data initialization subprogram,

B. Programs to define the equation of state and derivative and integral

functions,

C. Programs to calculate density if temperature and pressure are known,

D. Programs which calculate thermodynamic properties,

E. Programs to define the properties of the coexistence states,

F. Example of use of selected subprograms with sample output for

verification purposes.

For convenience, the subprograms in section 3.7 are arranged in alphabetical

order.

3.1 Data Initialization Subprogram

The data initialization subprogram in this package is SUBROUTINE

DATA C2. The various coefficients and constants in this subprogram are taken

from this work. A call to this data initialization routine need be made only

once but must precede the call to any other subprogram in this package. A write

statement in this program prints a reminder of the range of applicability of the

equation of state.

132
3.2 Programs to Define the Equation of State and Derivative and Integral

Functions

The program PROPS is a multiple entry program which calculates the pressure

and various derivatives for the calculation of other properties. All entries for

this subprogram are for input variables of temperature (TT) and density (DD).

All return arguments are given the variable name PP.

3.3 Programs to Calculate Density if Temperature and Pressure are Known

The programs listed in Table C-2 perform iterative solutions of the equation

of state for known values of temperature and density. The FUNCTION FIND D uses a Newton method iteration which defaults to the Regula-Falsi method in the case of

divergence. The Regula-Falsi method is to be avoided whenever possible because

it is considerably slower than other methods.

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

bi bliogrophy or literature survey, mention it here) A thermodynamic property formulation for ethylene, developed as a part of a joint

industry-government project, is presented. The formulation includes an equation of

state, vapor pressure equation, and equation for the ideal gas heat capacity. The

coefficients were determined by a least squares fit of selected experimental data.

Comparisons of property values calculated using the equation of state with measured

values are given. The equation of state is not valid in the critical region

(Pc + 0.3 Pc for temperatures of T^ + 0.05 T^). Errors on the order of

20 percent for derived properties and 10 percent for density may be encountered near the critical point. Tables of the thermodynamic properties of ethylene for the

liquid and vapor phases for temperatures from the freezing line to 450 K with

pressures to 40 MPa are presented. The equation of state and its derivative and

integral functions for calculating thermodynamic properties are included. Estimates

of the accuracy of calculated properties are given. A guide for use of computer

programs for the calculation of thermodynamic properties of ethylene with listings of

subprograms and a sample program to illustrate the use and results of the program are

incl uded.

NBS TECHNICAL PUBLICATIONS

PERIODICALS

JOURNAL OF RESEARCH—The Journal of Research of the National Bureau of Standards reports NBS research and develop- ment in those disciplines of the physical and engineering sciences in which the Bureau is active. These include physics, chemistry,

engineering, mathematics, and computer sciences. Papers cover a broad range of subjects, with major emphasis on measurement

methodology and the basic technology underlying standardization. Also included from time to time are survey articles on topics

closely related to the Bureau's technical and scientific programs. As a special service to subscribers each issue contains complete

citations to all recent Bureau publications in both NBS and non- NBS media. Issued six times a year. Annual subscription; domestic

$1.1; foreign $16.25. Single copy, $.1 domestic; $.V75 foreign. NOTE; The Journal was formerly published in two sections; Section A "Physics and Chemistry" and Section B "Mathematical

Sciences." DIMENSIONS/NBS—This monthly magazine is published to in- form scientists, engineers, business and industry leaders, teachers, students, and consumers of the latest advances in science and

technology, with primary emphasis on work at N BS. The magazine

highlights and reviews such issues as energy research, fire protection, building technology, metric conversion, pollution abatement,

health and safety, and consumer product performance, in addition, it reports the results of Bureau programs in measurement

standards and techniques, properties of matter and materials, engineering standards and services, instrumentation, and

automatic data processing. Annual subscription; domestic $11;

foreign $13.75. NONPERIODICALS

Monographs—Major contributions to the technical literature on

various subjects related to the Bureau's scientific and technical activities. Handbooks—Recommended codes of engineering and industrial practice (including safety codes) developed in cooperation with in- terested industries, professional organizations, and regulatory

bodies. Special Publications—Include proceedings of conferences sponsored by NBS, NBS annual reports, and other special publications

appropriate to this grouping such as wall charts, pocket cards, and

bibliographies. Applied Mathematics Series—Mathematical tables, manuals, and

studies of special interest to physicists, engineers, chemists,

biologists, mathematicians, computer programmers, and others engaged in scientific and technical work.

National Standard Reference Data Series—Provides quantitative data on the physical and chemical properties of materials, compiled from the world's literature and critically evaluated. Developed under a worldwide program coordinated by NBS under

the authority of the National Standard Data Act (Public Law

90-396).

NOTE; The principal publication outlet for the foregoing data is the Journal of Physical and Chemical Reference Data (JPCRD)

published quarterly for NBS by the American Chemical Society

(ACS) and the American Institute of Physics (AIP). Subscriptions,

reprints, and supplements available from ACS, 1 155 Sixteenth St., NW, Washington, DC 20056.

Building Science Series—Disseminates technical information developed at the Bureau on building materials, components,

systems, and whole structures. The series presents research results,

test methods, and performance criteria related to the structural and

environmental functions and the durability and safety characteristics of building elements and systems.

Technical Notes—Studies or reports which are complete in themselves but restrictive in their treatment of a subject. Analogous to monographs but not so comprehensive in scope or definitive in treatment of the subject area. Often serve as a vehicle for final reports of work performed at NBS under the sponsorship of other government agencies.

Voluntary Product Standards—Developed under procedures

published by the Department of Commerce in Part 10, Title 15, of

the Code of Federal Regulations. The standards establish nationally recognized requirements for products, and provide all concerned interests with a basis for common understanding of the

characteristics of the products. NBS administers this program as a supplement to the activities of the private sector standardizing

organizations. Consumer Information Series—Practical information, based on NBS research and experience, covering areas of interest to the con- sumer. Easily understandable language and illustrations provide

useful background knowledge for shopping in today's technological marketplace. Order the above NBS publications from: Superintendent of Documents, Government Printing Office, Washington. DC 20402. Order the following NBS publications—FIPS and NBSIR's—from
