Transfer units Chan-Fair correlations

Chan and Fair Method. Chan and Fair (1984a) retained the AIChE (1985) procedure for calculation of the but developed an alternative correlation for the number of transfer units in the vapor phase Nj/ as follows ... [Pg.313]

We will repeat the estimation of the numbers of transfer units using the Chan and Fair correlation for the number of transfer units for the vapor phase. The fractional approach to flooding is... [Pg.316]

For the liquid-phase Chan and Fair make use of the AIChE correlation thus, N/ = 8.412, as calculated above. The overall number of transfer units follows from Eq. 12.1.17 as... [Pg.316]

In order to calculate the number of mass transfer units, the mass transfer coefficients must be estimated, either based on experimental data or from empirical correlations. The following correlation (Chan and Fair, 1984) was developed for binary systems, and specifically applies to sieve trays. In this correlation Nq and N are expressed in terms of residence time and interfacial area instead of the standard forms of Equations 14.26 ... [Pg.512]
