Abstract

The Helmholtz function for pure isobutane from a recent

correlation has been converted to a dimensionless form and a pressure-enthalpy chart based on this function has been generated

by computer. A Helmholtz function for mixtures of isobutane and

isopentane has been formed based upon the dimensionless isobutane

Helmholtz function as the reference fluid by means of an extended

corresponding-states principle. Scarce literature data for saturation properties of isopentane, and new data for its vapor Dressure

and for the critical line of the mixture were used. The accuracy

of the surface was checked by comparing with literature enthalDy

data and with new VLE data for the mixture. Tables of thermodynamic properties have been generated from this Helmholtz function for the 0.1 mole fraction isopentane-in-isobutane mixture in

the single-phase region and on the dew- and bubble-point curves,

together with properties of the coexisting phase. A pressureenthalpy chart for this mixture has also been generated.

Introduction

Interest has been growing for several years in the use of isobutane

and isobutane-isopentane mixtures as working fluids In binary geothermal

power cycles. While these substances appear to have desirable characteristics

for such uses, including the possibility of "tuning" the properties of the

working fluid to the existing external conditions by adjusting the composition

of the mixture, there has been in the past a scarcity of experimental data

available and no good basis for predicting with any accuracy the properties

needed by the engineer for the efficient design of these power cycles ^ \

The Division of Geothermal and Hydropower Technology of the Department of

Energy has supported for several years a program of research both to improve

the available experimental data base and to correlate these data for the

production of tables and charts of use to the designer of power cycles.

Preceding the work reported here, scientists at NBS prepared a new

correlation of the thermodynamic properties of isobutane, based on existing

data and new data taken at NBS^. Also, a subregion around the critical

( 2 ) point was separately described by means of a so-called scaled equation: '

.

For isopentane, only scarce data were available. The data base available

for the mixtures was limited to some data on the location of the critical

line obtained at NBS, and a report on enthalpy-of-mixing data. The program

TRAPP, developed at NBS^, allowed prediction of single-phase thermodynamic

properties of the mixture of isobutane and isopentane by means of a generalized

principle of corresponding states. A serious drawback was, however, that

the reference function used in this program was methane. Therefore, the

TRAPP predictions of the properties of isobutane, the principal component

in the mixture of interest here, were substantially less accurate than the

thermodynamic surface that we already had developed for this fluid. We

therefore decided to follow the principle embodied in the program TRAPP,

but to use our own thermodynamic surface for isobutane as the reference.

The use of the principal component of the mixture as a reference should

lead to a significant increase in the reliability of the property predictions.

1. DIMENSIONLESS REFERENCE FUNCTION FOR ISOBUTANE

The global Helmholtz function representing the thermodynamic surface

(21 for pure isobutane has been described in two earlier publications' . For

use as the reference function for mixtures this Helmholtz function was

converted to a dimensionless form in the following way:

Definitions . Quantities in the reduced dimensionless form will be

represented with a "bar" above the symbol. The reduction parameters will

be represented as symbols with an asterisk ("*") or double asterisk as

superscripts. The primary reduction parameters are:

Temperature T = 407.84 K

Density p* = 3879.6 mol/m

(la)

Pressure P = 3.6290 MPa

These reference constants are the best estimates of the critical point of

isobutane^ 3,3 ^

The Fundamental Equation . The Helmholtz energy function as described,

in ref. ( 2 ) can, with a little re-arranging, be written as:

where the A^ a$e of ref. ( 2 ) has been separated into two functions: A-j

containing those parts of Aba$e depending on the "pseudo" second virial B,

and A^ those parts involving the "excluded volume" b. Dividing this equation

^ 1 by the reduction parameter A and defining p = V we have the fundamental

equation in dimensionless form:

The Helmholtz function for pure isobutane excludes a small region

about the critical point inside of which the values predicted for the

thermodynamic functions are less accurate. This region transforms, in the

dimensionless units, to an excluded region defined by 0.7 <

p" < 1.3 and

0.985 < T < 1.015. Within this region a separate equation using scaling

theory has been formulated^

2. THE THERMODYNAMIC SURFACE FOR ISOPENTANE .

A Helmholtz function for pure isopentane was next constructed from the

Helmholtz function for pure isobutane using extensions to "simple" corresponding

states^*®*^*®^. In the following description of this method we will use

the subscript 4 to refer to isobutane, and 5 to isopentane. The superscript

c will be used to refer to a critical point value.

Let us first define the following quantities:

The properties of isopentane used in this definition are made dimensionless

by means of the same reference constants as those of isobutane (see eq

(1)). The critical constants of isopentane we have used are listed in

Table 2a. They were determined at NBS within the framework of another

contract^)

Since no two substances obey the principle of corresponding states

exactly, Rowlinson et al . ^

and Leland et al . ^*8) proposed to generalize

the principle through the use of two functions, e(V,T) and $>(V,T) to be

defined, in the dimensionless system we are using here, through:

These functions e and $ are expected to be slowly varying functions of

c c and T^; to not be greatly different from unity since Zg / is close to

unity; and to be constructed such that eq (17) will be satisfied for the

real fluids and with this new f, q and h substituted for the fg, qQ

With h defined in this way, the real no longer appears in the formulation.

In its place appears a constructed given by hV^, which, depending on the

choice of the function $, may or may not have the same* value as the real

one. We shall use the symbol for this constructed quantity. This

quantity was chosen as the one to be constructed since Vg is less well

known than Pg or Tg.

Our choice for the functions e and $ was made through the following

steps:

1. The decision was made to map the vapor pressures and coexisting

densities of the pure isopentane onto the pure isobutane surface. There

have been vapor pressure measurements taken at this laboratory as a part of

(13l this project covering the range of 97°C to 181°C V '

. Measurements of the

(9) coexisting liquid and vapor densities have been made many years ago

v

,

over the range of 0°C to 180°C, but it was felt that the higher temperature

values might be less reliable. This method requires a temperature region

where both vapor pressure and coexisting densities are available, so our

efforts were concentrated in the range of overlap, 80°C < T < 140°C. A

preliminary fit of a simple empirical function to the vapor pressure data

was made to make interpolation possible in order to obtain vapor pressures

at the same temperatures as the coexisting density data.
- 11 -

2. A numerical value for 0 and $ at each chosen temperature point was

found through the following iterative process:

a. Assume a starting value for 0 for instance, 0=1. Call it 0g.

b. may now be calculated from the input temperature from

T

(P*

c. From the reference Helmholtz function for pure isobutane calculate

the corresponding vapor pressure ^45(^4).

d. From the isobutane reference function and this T4 and P4S

find the saturation density p^.

e. Obtain a value for $ from $ = p^/Cpg fig).

f. Obtain a new value for 0 from the input pressure through

0-j = 4> where the is obtained from the empirical function obtained

in step 1

g.

Increment the value for 0. and repeat steps a through f until a 0.

is found such that 0^ = 0.. We now have a numerical value for 0 and $ at

the chosen point.

3. With this set of numerical values for 0 and $ at each of the

chosen points, empirical functions for 0 and $ were constructed to

represent them as functions of the density and temperature with the additional

imposed restraint that the value never differs greatly from unity over the desired

range of temperatures and densities of the global surface. The value at the

critical point could have been fixed, but allowing this value to float made

easier the task of representing the 0 and $ at lower temperatures. In fitting

to the chosen empirical functions for 0 and $, the values at the critical point

were so close to unity that fixing them at unity caused no significant degradation

The values of the constants a-j through are given in Table 2b.

Also required for the complete description of the thermodynamic surface

of isopentane is the ideal -gas Helmholtz function for isopentane. For this

we interpolate in the table of ideal gas thermodynamic functions of isopentane

compiled by Scott

3. GENERALIZED CORRESPONDING STATES FOR THE MIXTURE .

The principles of corresponding states can be extended to include

mixtures through an approximation usually referred to as the "one-fluid"

model. In this model the assumption is made that the configurational

Helmholtz function for the mixture (less the ideal-mixing term) can be

represented as the Helmholtz function for a single equivalent substance,

and the finding of the parameters describing this substance becomes our

task.

For a mixture of molar fraction x of isopentane (and 1-x of isobutane),

molar volume Vx and temperature T , we obtain the configurational Helmholtz

function from that of isobutane in the same manner as for pure isopentane

by the relations

Equations (21) insure that for x=0 (pure isobutane) f and hx will be

Left to be defined are the constants V

c and Tc of eqn. (21). We

A A

will refer to them as "pseudocritical " constants, since they will define

the shape the line of critical points would have if the composition of the

liquid and vapor phases were constrained to be the same; that is, the locus

p p of ( 3 P/a V) Tx = 0, (a P/3V )jx

= 0 for the homogeneous mixture. In reality,

the mixture separates because of material instability prior to reaching the

"pseudocritical" line; the real critical line will be determined by a

method to be described later.

Many different prescriptions for obtaining Vx

proposed, referred to as mixing rules. The one we chose is the

"van der Waals" type rule:

rules":

c t^I/2

(23)

These definitions allow two more adjustable parameters, k and £, which

change the shape of the pseudo-critical line (and also the real critical

line) and which we can use to improve agreement with any mixture data that

might be available. As a part of another project, measurements have been

made at this laboratory of the critical temperature, pressure and volume of

pure isobutane, pure isopentane and of mixtures at three
-14-

( 1 2 ) compositions' . The critical temperature of isobutane predicted by the

global reference function is about 2°C higher than the physical value.

This was done on purpose: relaxing the tightness of the fit to the immediate

vicinity of the critical point greatly enhances the quality of the fit in

the supercritical region. The corresponding-states principle used here induces

a similar offset at the pure- isopentane critical point. We chose the

values for k and i such that this offset also occurs at the measured mixture

critical points. The parameters k and i are found to be close to unity,

and are listed in table 2c.

The ideal -gas portion of the total Helmholtz function is computed as

a linear combination of the ideal-gas functions for the pure substances and

ideal mixing term:

The Helmholtz function for the mixture is now complete. All thermodynamic

properties obtainable through combinations of derivatives with respect to

V or T may still be calculated in this way. One more property, the chemical

potential, necessary for the determination of coexisting phases and the

real critical line, remains to be determined. It differs from the other

properties described in that it requires derivatives of the Helmholtz

function with respect to x.

Calculation of the chemical potentials

The chemical potentials, defined as

y4

("P* T, x) - ^ - x( 3^/ 3x)

p j

y

(P, T, x) = G + (1 - x) (3G/3x)

P jT

( 25 )
- 15-

are calculated here using numerical derivatives AG/ ax. Since it can be

shown that (3G/3x)

p T

= (3A/3x)y we chose the latter form for the

derivative as a convenience, since the natural independent variables of the

reference function are V and T. In terms of derivatives of the Helmholtz

function, the expressions for the chemical potential of the two components

are:

= ft(?,T,x) + p V - x(AA/Ax)y

>T

( 26 )

and u

5 = ft(V,T,x) + p V + (1 - x) (aA/ax)^

y

Prediction of coexisting states

With the chemical potentials now available, we are in a position to

predict the location of the phase boundary. For the liquid and vapor to.be

in equilibrium, the chemical potential of each component must be the same

on each side of the phase boundary. That is:

p4l(P>T,xl

) =

P4y

(P»T,Xy)

P5l(P>T»X|^) = (P»T»Xy),

( 27 )

where the subscripts L and v refer to liquid and vapor, respectively. At a

specified P and T this becomes a system of two non-linear equations in the

two unknowns x^ and x

y

. The solutions were obtained using a commercially

available package of programs for solving non-linear problems. All methods

for solving systems of non-linear equations require a mechanism for guessing

the values of the unknowns to be used as the initial values for an iterative

process. In regions where the values of the unknowns are well separated,

the requirements on the accuracy of the guesses are not very stringent.

For temperatures below the critical temperature of either component, the P-x

dew and bubble curves run from x=0 (vapor pressure of pure isobutane) to
-16-

x=l (vapor pressure of pure isopentane). This can be seen graphically in

fig. 7. Here an initial guess for x

L is obtained by interpolation, at the

specified pressure P, on the bubble curve for the specified temperature T.

The bubble curve is approximated by a straight line in P-x space, connecting

the vapor pressures of the individual components. Thus

x, = , (28)

L DO D O k

4

k

where the superscript 0 indicates the vapor pressure of the respective pure

component. A first estimate for Xy then follows from Dalton's law applied

to the vapor phase:

x

y

= 1 - (l-x

L )P4

°/P. - (29)

If the specified temperature T is between the two critical temperatures,

the dew and bubble curves in P-x space begin at the isopentane vapor pressure

and meet at the critical line (cf. fig. 7). We approximate the bubble

curve by a straight line running from the point P

c

, x

c

, which is determined

once T is specified, to Pg° at x=l . We now apply Raoult's law to a mixture

consisting of isopentane and a virtual component with vapor pressure P .

We then obtain as an estimate for x^:

X

Application of Dalton's law to the vapor phase of this mixture leads to

x

Y

« 1 - (l-x

) Pc/P ( 31 )

as a first guess of the vapor composition.
- 17 -

As either end point of the coexistence curve is approached, the values

for x

L and x

y

become nearer to each other, and the required accuracy of the

Initial guesses for these quantities increases, especially at the higher

temperatures. This we accomplish by making our first calculation near the

middle of the region of coexistence, and then approaching the ends with

small increments of P, if properties along an isotherm are being calculated,

or of T, if properties along an isobar are being calculated. With each

calculation after the first, the initial guesses for Xj_ and x

y are taken as

the final result of the previous calculations. Even so, a point is always

reached very close to the critical point where the calculation breaks down

computationally, and a solution cannot be reached.

Prediction of the critical line .

For a pure fluid, the critical point is defined as that point where

(ap/ap)j and (3 p/3p )y are simultaneously zero, because of incipient

mechanical instability. The critical point for a fluid mixture of two

components, where x is the concentration of the second component, is defined

as the point where (3y/3x)p

y

and (3 y/3x )p y are simultaneously zero

because of incipient material instability. The location of this point is

computed in the following way: The condition that these two derivatives be

simultaneously zero can be seen, according to the definition of the y's in

eq ( 25 ), to be equivalent with requiring that (3 G/3x )p y

and (3 G/3x ) p y

be simultaneously zero. The condition that (3 G/3x )p y

be zero defines a

surface, called by van der Waals a "spinodal", which must lie within the

two-phase region but be tangent to the real two-phase region at the point

of maximum pressure for an isotherm plotted in the P vs x plane. (See

diagram in fig. 1 , and discussion in ref. ( 11 )) This point of contact, at

a maximum of P, is the point that satisfies the other condition, that

(3 G)/(3xJ

)p y

be zero and is the real critical point for the specified T.

This point is found through a search, at the specified T and a trial x, by
-18-

scanning over a range of densities and searching for the P at the point

2 2 where (3 G/ax ) p j

= 0. This search is repeated at the same T but a different

2 2 x until the x is found for which the P is a maximum while (a G/ax ) p y

= 0.

4. COMPARISONS WITH EXPERIMENTAL DATA .

For comparisons of the rather sizeable body of data available for pure

(21 isobutane with the isobutane reference function, see Waxman and Gallagher v y

.

The available experimental data for isopentane are much more sparse, and

additional data are being taken at this laboratory as a part of this project

to supplement those already available. The vapor pressures of pure isopentane

» have been measured over the range from approximately 97°C to 181°C. Table

3a compares these measurements with the values predicted from the Helmholtz

function. The fractional differences between the measured vapor pressures

and these predicted are plotted in fig. 2. The estimated experimental

uncertainties of these measurements are 0.1%. As can be seen, the predicted

values agree well at the higher temperature end, but the differences become

somewhat larger at the lower temperatures. Additional data at lower temperatures

will be available soon, and at that time a redetermination of the shape

factors can be made which should improve the lower temperature results.

The coexisting liquid and vapor densities in the range 20°C to 180°C

(9)

were measured by Young v These measurements were taken 90 years ago and

are of unknown reliability. The comparison of these densities with the

predicted values, obtained by solving the Gibbs conditions at the specified

temperature, appear in Table 3b. These fractional differences between the

measured and predicted values are plotted in fig. 3. The agreement is

quite good for the liquid densities except at the highest temperature. On

the vapor side the differences are much larger, but this is to be expected

as vapor density measurements are much more difficult and were given much

less weight in the determination of the shape factors. We would not want

to improve these agreements if it would be at the expense of the fit to

other data.

Measurements of the critical temperature and pressure for mixtures of

three different compositions have been taken at this laboratory as a part

of another project^ 1 referred to in the section on predicting the critical

line. Figure 4 shows these critical temperatures as a function of the

composition. The dashed line on this plot is the critical line predicted by

the equation. These critical line data and the predicted values are also

tabulated in Table 3c. Note that this predicted critical line lies about

2°C higher than the measurements throughout as intended for the reasons

discussed earlier.

Morrison at this Laboratory has made measurements of the bubble pressures

and saturated liquid densities for isobutane-isopentane mixtures. His

(131

apparatus is described in some detail in another report^ '. It is a

cylindrical sapphire variable-volume phase-equilibrium apparatus, coupled

to a mercury displacement pump. Observations are done of the pressure and

the positions of the mercury and vapor-liquid interfaces at fixed temperatures

on a sample of known mass and known overall composition. By repeating

these measurements at a minimum of two compositions, but both times at the

same temperature and pressure, the densities and compositions of the coexisting

phases can be inferred without the need for sampling. Temperatures are

measured to better than 1 mK, pressures to 0.1% by means of a calibrated

pressure transducer, and the overall composition of the prepared sample is

' estimated to be reliable to +0.0002 in mole fraction. For the present

contract, Morrison measured bubble pressures and saturated liquid densities

for samples of 0.05 - 0.15 mole fraction of isopentane at approximately

15°C - 55°C in steps of 10°C. For another contract, he did similar measurements

for samples near 50% mole fraction. All measurements are listed in Table

3d. In this same table, we also compare the predictions of the thermodynamic

surface with these measured data. The comparisons are displayed in four

graphs, figs. 5a - d: two figures comparing pressure and two comparing

density. We note that our model predicts the densities for the 5-15%
mixtures to better than 1%. The densities of the 50% mixtures are predicted

with errors from 1-2%. The pressures of the 5-15% mixtures are predicted

to better than 0.5% at the highest temperature, but the surface does markedly

worse at the lowest temperatures. For the mixtures near 50%, the vapor

pressures are predicted within 1% at the highest temperature, but there are

systematic departures at the lower temperature. There is therefore room

for improvement. We are confident that the new data we are taking, and the

flexibility still present in the model, will allow us to do much better in

the next round of correlations.

n 2 1 Koppany and Lenoir'' ' reported measurements of the enthalpy of mixtures

of nominally 0.80 mole fraction of isobutane in isopentane. Enthalpies

were measured by injecting the mixture into a calorimeter at fixed pressure

and a measured temperature, and then cooling it isobarically to a liquid

state at 75°F. The enthalpy difference to this liquid reference state is

obtained from the hydrocarbon flow rate and the amount of refrigerant

evaporated.

The authors performed test measurements using pure isobutane at 250

psia. We have compared their measured enthalpy differences with those

predicted by our Helmholtz function for isobutane. The agreement was

strikingly good.

For the mixture, seven isobars were measured, six of which were subcritical.

Samples of the mixture were taken periodically throughout the runs and

analyzed for composition. The authors' preference has been to use the

average of these analyses as the composition, and therefore our predictions

have been made for these average compositions. In fig. 6, we have displayed

the data and our predictions for four of the isobars. The experimental and

predicted values are also tabulated in Table 3e. Our predictions generally

agree well with the data in the liquid phase, but are somewhat on the low

side in the vapor phase, especially near and above the critical point. The

authors' estimate of the location of the phase boundary is quite far from
- 21 -

the one predicted by our surface, especially at the vapor side beyond

200° F. We believe that it is very difficult to locate the phase boundary

from the enthalpy data alone because of their pronounced curvature in the

two-phase region. Although we have as yet no data for the saturated vapor

volumes near the critical point, we do have a direct measurement of T

c at

the 0.80 mole fraction of isobutane. Our measured value is about 6°F below

that estimated by the authors, which is consistent with our hypothesis that

the authors have overestimated the extent of the two phase region. Our

surface is certainly capable of some improvement in the supercritical lowdensity states.

The most worrisome aspect of the data is the strong curvature of the

isobars in the two-phase region. We are not hopeful that our model can be

made to exhibit such curvature. We do not think that the excellent results

obtained with this calorimeter for pure isobutane guarantee proper functioning

if a mixture is used. In particular, in this calorimeter, the sample is

entered into a side arm at the desired pressure, and then heated in a

relatively short section of tubing to the initial temperature. It may not be

possible for a mixture to reach complete composition equilibrium if the

desired initial state is in the two-phase region. This may explain why our

agreement with the one-phase data is so much better than with the two-phase

data.

5. RESULTS

Some of the predicted thermodynamic properties of this resulting

Helmholtz function are shown graphically in figures 7 and 8. Figure 7

displays the predicted dew-and bubble-point pressures for several subcritical isotherms as a function of the composition. The predicted critical

line is also included as a dashed line with the small circles indicating

the predicted critical pressure at the temperature of these isotherms.

Figure 8 similarly displays the predicted dew - and bubble-point densities

and the predicted critical line. The dashed portions of the isotherms are
- 22 -

those parts of the isotherms within the excluded region about the critical

line: that is, where 0.7 < < 1.3 and 0.985 < < 1.015. In the regions

very close to the critical points we experience computational difficulty in

the solving of the eq (27) for the conditions of coexisting phases.

Appendices A and B present tables of predicted values for the thermodynamic

properties of the isopentane in isobutane mixture. Appendix A is in SI

units and Appendix B in "engineering" units. Table 1 in each Appendix

shows the predicted values for coexisting liquid and vapor. The dew-point

tables were generated for a 0.1 mole fraction of isopentane in the vapor,

with the composition and predicted properties of the coexisting liquid also

tabulated. The bubble-point tables were generated for a 0.1 mole fraction

of isopentane in the liquid, with the composition and predicted properties

of the coexisting vapor also tabulated.

Table 2 in each Appendix includes properties in the single phase

region for the 0.1 mole fraction isopentane in isobutane mixture. They

were calculated along isobars and also include at phase boundaries the

composition and properties of the coexisting state.

Also included with this report are pressure vs. enthalpy charts for

pure isobutane and a mixture of 0.1 mole fraction isopentane in isobutane.

These charts were plotted by computer and show isotherms as solid lines,

isochores as dashed lines, isentropes as "dash - dot" lines and, in the two

phase region for the mixture, lines of constant quality as dotted lines.

The isentropes were calculated using a Newton-Raphson iteration where, for

the specified entropy, a range of densities was chosen and at each density

the temperature was determined, where C

y

/T = (3S/aT)

p was used for the

derivative in the iteration. The "excluded" region in the vicinity of the

critical point is left blank in the chart for the mixture because of the

expected reduction in accuracy of the values for the predicted properties

fn that region. In the chart for pure Tsobutane the plotted values in the
-23-

critical region were taken from a separate correlation of the critical

region^; it happens to join to the global equation at the boundaries of

the excluded region smoothly to within visual accuracy on the plot. In

addition to the improved accuracy, the charts cover a much wider range than

any heretofore available.

In Appendix C we have included the computer programs, written in

FORTRAN 77, which were used to generate the predicted properties of this

surface. The package includes subroutines for calculating the properties

of the isobutane reference function, for applying the corresponding states

principles previously described, and for converting to and from the internal

dimensionless units to any of a wide variety of desired external systems of

units. A main program is also included for generating a table of properties

along an isobar, which was used for generating the values in Table 5.

6. ESTIMATE OF RELIABILITY

The reference function for pure isobutane is generally in accord with

the sizeable body of data available for pure isobutane to within 0.1% to

0.15% differences in density over the specified range of 250 to 600 K and 0

to 40 MPa. (0 to 5800 PSIA). The predicted vapor pressures for pure isopentane

differ, in the worst case, from the measured values by about 0.9% and on

average by about 0.5%. A comparison of the predicted coexisting densities for

pure isopentane with the measured ones shows average differences of about

0.3% for the saturated liquid and up to 3% for the saturated vapor . The

agreement of the bubble-point pressures for the mixture with the measurements

of Morrfson range from + 2.4% to - 1.4% with an average difference of about

0.8%, and for the coexisting liquid densities the range of differences is -

2.0% to + 0.1% with an average difference of about -0.9%.

On the basis of these comparisons we would estimate the uncertainty of

the predicted vapor pressures to be about 0.5% for pure isopentane, increasing

to about 1% for the 50% mixture, then decreasing to that of the pure isobutane
as the mixture becomes more dilute in isopentane. The predicted densities

might be expected to have a similar behavior. Comparing a variety of

surfaces developed for the mixture, we find that the predicted enthalpies

and entropies are relatively insensitive to changes in the shape factors or

the critical line. Seldom did these properties change by more than one or

two units in the least significant figure displayed in the tables.

The range of validity for the mixture Helmholtz function might be

expected to be the same, in reduced units, as that for the pure isobutane

reference function.

7. CONCLUSION

This resulting Helmholtz function describing the thermodynamic surface can

be used to predict equilibrium thermodynamic functions' through the entire

composition range from pure isobutane to pure isopentane over a wide rangje

of temperatures and pressures. Additional measurements are being made

and as they become available, refinements will be made in the expressions for

the shape factors and the mixing parameters which should further reduce the

uncertainties. In particular, vapor pressure measurements are being made

on pure isopentane at lower temperatures which should improve the shape

factors in that region and at the same time we hope to improve the representation

of the saturated vapor densities for pure isopentane at the high temperatures.

Also more measurements of the PVTx relationship at the bubble points will

become available: these should also lead to improvements in the shape

factors. The accuracy of the predicted thermodynamic values in the singlephase regions for the pure Isopentane or for the mixture has not been tested

due to an absence of experimental data. We hope to have such measurements and

with them test the validity of this method of prediction. This method of

using a well-tested Helmholtz function for pure isobutane as the reference fluid

already gives a significant improvement fn accuracy over previously-used methods

where both components of the mixture were referred to a third fluid as the

reference fluid.

Fig. 1. Diagram showing a liquid-vapor phase boundary for a constant

temperature. The critical point for that temperature, P c and x

c> is

that point where the pressure is a maximum. The dashed line represents

the locus of points for which (3 2 G/3x2

) Tp

= 0, and the point of maximum

pressure for this function coincides with the point (

P

c

» x

c

) . This is

found through a scan, at the specified T and fixed x, in which the

density is varied in order to find the pressure where (3 2 G/3x 2

) Tp

= 0.

The value of x is varied until the maximum pressure is found. This

identifies P ,x for this particular temperature,

APPENDIX A.

Tables of Values for the Thermodynamic Properties

of the 0.1 Hole Fraction Isopentane in Isobutane Mixture

in SI Units.

Table A1 presents properties for both the dew-points

and the bubble-points and at increments of both temperature

and pressure. Also shown are the concentrations and thermodynamic properties of the coexisting phase.

Table A2 presents properties along isobars at increments

of temperature from the compressed liquid through the superheated vapor. At the bubble-points and dew-points the concentrations and values for the thermodynamic properties of the

coexisting phase are also shown.

ABSTRACT (A 200-word or less factual summary of most significant information. If document includes a significan t bi bliography or literature survey, mention it here)

The Helmholtz function for pure isobutane from a recent correlation has been

converted to a dimensionless form and a pressure-enthal py chart based on this

function has been generated by computer. A Helmholtz function for mixtures

of isobutnae and isopentane has been formed based upon the dimensionless

isobutane Helmholtz function as the reference fluid by means of an extended

corresponding-states principle. Scarce literature data for saturation properties

of isopentane, and new data for its vapor pressure and for the critical

line of the mixture were used. The accuracy of the surface was checked by

comparing with literature enthalpy data and with new VLE data for the mixture.

Tables of thermodynamic properties have been generated from this Helmholtz

function for the 0.1 mole fraction isopentane-in-isobutane mixture in the

single-phase region and on the dew- and bubble-point curves, together with

properties of the coexisting phase. A pressure-enthalpy chart for this mixture

has also been generated.
