O’Connell’s correlation

Using O Connell s correlation, estimate the overall column efficiency and the number of real stages required for the separation given in Example 11.5. [Pg.551]

Lockett (12) and King (126) noted some theoretical sense in O Connell s correlation. Higher viscosity usually implies lower dif-fusivity, and therefore, greater liquid phase resistance and lower efficiency (12). Higher relative volatility increases the significance of the liquid phase resistance [Eq. (7.13)), thus reducing efficiency (126), Lockett expressed the O Connell plot in equation form... [Pg.376]

An important reference often used for design is O Connell s correlation of tray efficiencies. This work is an improvement of an earlier publication by Drickamer and Bradford. In O Connell s correlation (Fig. 10), it is assumed that mass and heat transfer depend on diffusivities and liquid viscosity, and that both effects can be correlated by using the liquid viscosity and the component relative volatility for the separation. [Pg.276]
