The liquid viscosity can be estimated using the data given in Appendix D. Use the De Priester charts to determine the relative volatility. Use the short-cut methods and follow the procedure set out below. The column will operate at 14 bar and the feed will be at its boiling point. Make a preliminary design for a column to recover 98 per cent of the n-butane overhead and 95 per cent of the isopentane from the column base. The composition of the feed to a debutaniser is given below. The equilibrium K factors can be estimated using the De Priester charts in Chapter 8. Īt a pressure of 10 bar, determine the bubble and dew point of a mixture of hydrocarbons, composition, mol per cent n-butane 21, n-pentane 48, n-hexane 31. The K values, taken from the De Priester charts (Chapter 8), are plotted in Figure (a) for easy interpolation. values for hydrocarbons, high temperature.
These charts give the K-values over a wide range of temperature and pressure. Ī useful source of if-values for light hydrocarbons is the well-known De Priester charts, Dabyburjor (1978), which are reproduced as Figure 8.3a and b.
