Statistical Thermodynamic Model for Viscosity of Pure Liquids and Liquid Mixtures Weihong Cao: Aage Fredenelund,* and Peter Rasmuseen Engineering Research Center IVC-SEP, Institut for Kemiteknik, The Technical University of Denmark, DK-2800 Lyngby, Denmark

On the basis of statistical thermodynamics, local compositions, and Eyring’s absolute rate theory, a new viscosity model for pure liquids and liquid mixtures has been developed. The model can be used to describe the viscosity of pure liquids a t different temperatures and of liquid mixtures at different compositions and temperatures. Correlation of viscosity data of 314 pure liquids and of 215 binary systems and prediction of viscosities for 14 ternary systems and 1 quaternary system have been carried out. The pure liquids include water, alcohols, organic acids, ketones, ethers, acetates, aldehydes, amines, aromatics, and other hydrocarbons, and the binary and multicomponent systems include mixtures with nonpolar + nonpolar, polar + polar, and nonpolar + polar components. The overall average MRSD (mean relative standard deviation) of the correlations of the pure liquid viscosities is 1.13%, and that of the binary systems is 0.80%. The overall average MRSD of the predictions of the multicomponent systems is 2.90%.

Introduction Information on the viscosity of pure liquids and of liquid mixtures is important in applications in chemical engineering, such as in the determination of flow in pipelines, mass-transfer operations, etc. Viscosity data of pure liquids and liquid mixtures at different temperatures, pressures, and compositions have been reported in the literature. Some of the viscosity data are published in the collection by Viswanath and Natarajan (1989) and by Stephan and Hechenberger (1988). A thorough review on models for viscosities of liquids may be found in Reid et al. (1987). The principle of corresponding states (Helfand and Rice, 1960; Gubbins, 1973; Teja and Rice, 1981) and Eyring’s absolute rate theory (Glasstone et al., 1941) have been widely used to describe the viscosity of pure liquids and liquid mixtures, see Hwang and Whiting (1987) and Wei and Rowley (1985). Moat of the correlation equations for viscosity of pure liquids are accurate but empirical and are not valid for the viscoeity of liquid mixtures. Models for viscositiea of liquid mixkvee have been reported in the literature and reviewed by Irving (1977a,b) and Reid et al. (1987). Most of the equations are based on the principle of cormponding state and Eyring‘s absolute rate theory. McAllister’s model (McAuister, 1960) is baeed on Eyring’s absolute rate theory including three-body or four-body interactions. It is widely umd to correlate the experimental viscosity data of liquid mixtures, but the parameters in McAllister’s model are Present address: DeDartment of Chemistry. Tsinahua

strongly dependent on temperature (Asfour et al., 1991). In 1986, Wu developed a group contribution method for predicting the viscosities of liquid mixtures. The method is a combination of Eyring’s absolute rate theory for pure components with the UNIFAC model. The purpose of this paper is to develop a viecosity model to be umd for correlating the viscosities of pure liquids and of binary systems, and from these results to predict the viscoeities of multicomponent systems. The model is b a d on statistical thermodynamics and on Eyring’s absolute rate theory. The concept of local compoeition is introduced into the model. The correlation of viscosities of 314 pure liquids, including water, alcohols, organic acids, ketones, ethers, acetates, aldehydes, amines, aromatics, and hydrocarbons,and for 216 binary systems, including nonpolar + nonpolar, polar + polar, and nonpolar + polar components, and the predictions for 14 ternary system and 1 quaternary system have been carried out. Good agreement between experimental and predicted results is obtained.

Statistical Thermodynamic Model On the basis of lattice theory (Guggenheim, 1952), the partition function of a pure liquid i can be written as

For a liquid mixture, following Abrams and Prausnitz (1975),we represent a molecule as a set of segments, using Staverman’s model (1950) as the boundary condition, and 0 1992 American Chemical Society

we introduce local composition. The partition function of the liquid mixture is obtained from eq 1:

in the liquid. The work for movement to activation s t a b is given by ea

where Q is the partition function of the mixture, oi is the number of distinguishable configurations of lattice i, variables with superscript s are those of Staverman’s model, n is the number of components in the liquid mixture, Ni is the number of molecules of component i, mi is the mass of a molecule i, Tis the temperature, h is Planck’s constant, k is Boltzmann’s constant, and U, is the potential energy of the lattice i in the mixture:

= f&(&/2)

(8)

where f is the shear force per unit area, l2 and la are the distances between two equilibrium positions of neighbor molecules in the same molecular layer, and it is assumed that the activation energy barrier is symmetric between two neighbor equilibrium positions. If a molecule movea in the forward direction of the ahear force, it will obtain the work. The frequency of this direction is

(3) In this expression, z is the coordination number of the lattice, qi is the area parameter of molecule i, Vii is the interaction potential energy between sites i and j , and eji is the local composition: (4)

If a molecule movea in the backward direction of the shear force, it will overcome the work. The frequency of this direction is

where ( i ) and (i), are molecule i at normal state and at activation state. The frequency of the pure liquid i can be obtained from eq 7:

For a liquid mixture, an equivalent expression is obtained by postulating the following reaction scheme:

The frequency of the liquid mixture can be obtained from eq 11:

Viscosity Equations for Liquid Mixtures Based on Eyring’s absolute rate theory (Glasstone et al., 1941), there is an activation energy barrier between two nearest equilibrium positions of molecules in a liquid. If a molecule in the liquid moves from an equilibrium site to another, the molecule has to overcome an energy barrier. If there is a shear force on the liquid, the molecular movements from one balance position to another in different directions of the liquid are different. If the shear force is equal to zero, the movements in different directions of the liquid are the same, and the frequency of these movements can be expressed as k, = kT Qa exp( h Q

g)

(7)

where k, is the movement frequency of one molecule, Q, is the partition function of activated state, and U, is the activation energy of a molecule. If there is a shear force, the movements in the forward and backward directions of the shear force are different because work is done by the shear force to the molecules

where N is the number of molecules in the liquid mixture (N = C N J . Eyring et al. (Glasstone et al., 1941) have for a number of systems compared the deviations of the observed energy of activation for flow in mixtures from the linear additive law with the deviation from Raoult’s law. The comparison shows a close relationship between the energy of activation and the free energy of mixing. Eyring et al. determined the energy of activation from the internal energy of vaporization at the normal boiling point multiplied by a general constant. Wu (1986) determined the energy of activation from the free energy of mixing multiplied by a general constant. Here we assume that the activation energy is directly proportional to the potential energy of molecule i in the liquid mixture

U, = niUoi

In this equation, f is the shear force per unit area, u is the velocity of a molecular layer, ll is the distance between two molecular layers, Au/ll is the local velocity gradient, 7 is the dynamic viscosity of the liquid, and Au is the difference of velocity of molecdar layers and can be shown to be -Au = &(kf - kb) (16) Substitutions invohing eqs 3,8-10, arid 12-16 reedt in the following expression for the dynamic viscosity of pure liquid i:

Comparison to Other Models New viscoaity equations of pure liquids and liquid mixhues may be compared with some well-known viscoeity equations. The relationship between the viscosity of liquids and the temperature was proposed as the following expreasion: ln(d = A

by de Guzman (1913). Modifications of eq 25 have been reported to improve ita correlation accuracy; many include some function of the liquid molar volume in either A or B ( h i d et al., 1987). If we let

The dynamic viscosity equation of the liquid mixture becomes

Comparing it with eq 18, the expression of AG* given by McAllister is very similar to the expression in eq 18 if twdmdy interaction is assumed. The main difference is the P6in the first part of the two new viscosity eqs 17 and 18. Because the parameters in McAlliater’s equation are strongly dependent on temperature, the P6term is very interesting. On the basis of the free volume theory, Dymond and Brawn (1977) presented a liquid viscosity equation: 9

are obtained. In these equations, vi is the kinematic viscosity of the pure liquid i, Y is the kinematic viscosity of the liquid mixture, and M is molecular weight of the liquid mixture. For liquid mixtures, it is convenient to combine eq 18 with eq 17 and eq 21 with eq 20. Then the dynamic viscosity equation of the liquid mixture becomes

(26)

then the viscosity equation obtained in this paper, eq 17, reduces to eq 25 but A includes temperature and molar volume and B is slightly dependent on temperature. The widely used viscosity equation by McAlhter (1960) is based on the following viscosity expression obtained from Eyring’s absolute rate theory (Glasstone et al., 1941):

then eq 22 is reduced to eq 29. Reid et al. (1987) reviewed the new developments of the one-parameter GrunbergNissan correlation which are (1)the parameter has become a function of temperature; (2) the parameter is a function of composition, and (3) the parameter is estimated by group contribution. In this work, the parameter G12 of the new viscosity equation is a function of temperature and composition.

Correlations of Viscosity Data of Pure Liquids The new viscoeity equations for pure liquids, eq 17 and eq 20 can be used to correlate viscosity data of pure liquids at different temperatures. In the two equations, qi is calculated from the surface area of the UNIFAC group (Hansen et al., 1991), Vi and Mi are obtained from DIPPR data bank (Daubert and Danner, 1989), and z is calculated from the following equation (SkjoldJolrge~senet al., 1980): z = 35.2 - 0.1272T

To examine the applicability of the new viecosity equations for pure liquids, the experimental viscosity data of 314 pure liquids including water, alcohols, organic acids, ketones, ethers, acetates, aldehydes, amines, aromatics, and other hydrocarbons have been correlated. All experimental viscosity data of the pure liquids were obtained from the DIPPR data bank. Then the coefficients of ni in eq 36 for the 314 pure liquids are obtained, and the viscosity data of the pure liquids at any temperature are calculated.

The interaction potential energy parameters, Vii - Vi, are unknown. They are obtained by correlating experimental viscosity data for binary systems. For the binary systems, there are two interaction potential energy parameters, U2, - Ul, and U12- U22.They are determined by fitting eqs 22 and 23 to the experimental viscosity for binary systems. The objective function of the computation of these parameters is as same as eq 37. To examine the applicability of the new viscosity equations to liquid mixtures, the experimental viscosity data of 216 binary systems including nonpolar + nonpolar, polar + polar, and nonpolar + polar components have been correlated with the equations. All experimental viscosity data of the binary systems were obtained from the Journal of Chemical and Engineering Data. Figure 3 shows the calculated viscosity data and the experimental viscosity data for the chloroform-toluene binary system. Figure 4 shows the calculated kinematic viscosity and the corresponding experimental data for the 1,2-dichloroethane-

Predictions of Viscosity Data for Multicomponent Systems For multicomponent systems, the new viscosity equations for liquid mixtures, eqs 22 and 23, can be used to predict the viscosity data of multicomponent systems if all parameters in the equations have been obtained from the relevant pure liquids and binary systems. To examine the reliability of the new viscosity equations for liquid mixtures and the parameters obtained above, the Viscosity data of 14 ternary systems and 1quaternary system in-

cluding nonpolar + nonpolar, polar + polar, arid nonpolar + polar components have been predicted and compared with the experimental data. All parameters, ni and Uji Uii,used in the predictions for multicomponent aptem are obtained from the correlations of viecoeity data for pure liquids and binary systems. They are listed in Tables 11 and III. All experimental viscosity data of the multicomponent systems were obtained from the Journal of Chemical and Engineering Data. Figure 6 shows the prediction deviations of the 15 multicomponent system. The detailed prediction results, such as number of experimental points, temperature, and MRSD of each

NUMBER OF MULTICOMPONENT SYSTEMS

Figure 6. Overall MRSD of the predictions of 15 multicomponent systems.

multicomponent system, are listed in Table IV. The overall average MRSD of the predictions is 2.90%. The viscosity data of the 15 multicomponent systems have been predicted by the UNIVISC model (Wu, 1986) and compared with the experimental data. The prediction deviations are listed in Table IV and shown in Figure 6. The overall average MRSD of UNMSC model is 5.68%. The results show the new viscosity equations for liquid mixtures can be used to predict viscosity data of multicomponent systems with good accuracy.

Conclusion Based on statistical thermodynamic model, local composition, and Eying‘s absolute rate theory, a new viscosity model for pbre liquids and liquid mixtures has been developed, and the new dynamic and kinematic viscosity equations for pure liquids and liquid mixtures are obtained. The equations can be used to correlate the viscosity data of pure liquids as a function of temperature. For binary systems, the equations can correlate viscosity data even if the data are at different temperatures. Figure 7 shows the correlation of viscosity data for the 1,Cdioxane-ethanol system at different temperatures, using one set of binary parameters which are temperature independent. The equation can be used to predict viscosity data of multicomponent systems. The correlation of 314
