Ethanol takes part in a reaction at 300°C, with a partial pressure of 30 atm. Table 10.1 gives the critical point data, which are Tc=516 K, and Pc=63 atm. What is the fugacity under these conditions In this case we have reduced temperatuie=777 =573/516= 1.11, and reduced pressurc=/y/Jce=30/63=0.48. From Fig 7.7, we find y=f/P=0.92. Thus / =yP=27.6atm. [Pg.103]

To this point we have applied the critical temperature to both viscosity and density calculations. Already this critical property Tc is seen as valued data to have for any hydrocarbon discrete single component or a mixture of components. It is therefore important to secure critical temperature data resources as much as practical. I find that a simple table listing these critical properties of discrete components is a valued data resource and should be made available to all. I therefore include Table 1.3 listing these critical component properties for 21 of our more common components. A good estimate can be made for most other components by relating them to the family types listed in Table 1.3. [Pg.15]

Values converted from tables of Sbank, Theimodynarmc Propeities of UCON 245 Refiigerant, Union Carbide Corporation, New York, 1966. See also Sbank, ] Chem. Eng. Data, 12, 474 80 (1967). c = critical point. Tbe notation 6.46.—4 signifies 6.46 X 10" [Pg.340]

Values interpolated and converted from tables of Kang, McKetta, et al.. Bur. Eng. Res. Repr. 59, University of Texas, Austin, 1961. See also J. Chem. Eng. Data, 6 (1961) 220-227 and Am. Inst. Chem. Eng. ]., 7 (1961) 418. c = critical point. The notation 6.189.—4 signifies 6.189 X 10 . The AIChE publication contains a Mohier diagram to 4500 psia, 480 F, while the reprint contains saturation and superheat tables. [Pg.346]

Values converted and mostly rounded off from those of Goodwin, NBSIR 77-860, 1977. t = triple point c = critical point. The notation 3.O.—9 signifies 3.0 X 10 . Later tables for the same temperature range for saturation and for the superheat state from 0.1 to 1000 har, 85.5 to 600 K, were published by Younglove, B. A. and J. F. Ely, J. Fhys. Chem. Ref. Data, 16, 4 (1987) 685-721, but the lower temperature saturation tables contain some errors. [Pg.310]

If the potential parameters for the pure components are not found in the tables given in (Hll) and (Bll), and if viscosity and second virial data are not available for their determination, then for the Lennard-Jones (6-12) potential it is possible as a last resort to estimate these parameters from the properties of the substance at its critical point c, its melting point m, or its boiling point b these relations give /k in °K. and a in Angstrom units (1 A. = 10-3 cm.)

We are interested in using the BACK equation for hydrogen mixtures. Therefore we have determined equation constants for hydrogen, and these are included in Table I. PVT data (7) at temperatures of 111-2778 K and pressures up to 1020 atm are used in this determination. Neither vapor-pressure nor critical-point data are used to avoid complications owing to quantum effects. It is found necessary to adopt an unusual value of the constant C of 0.241. With this C value the calculated pressure shows a relative root-mean-squared deviation of 0.5% and a relative bias of less than 0.1%. [Pg.218]
