Mass transfer to packed beds

In packed beds, mass transfer coefficients are often correlated by means of a Chilton—Colburn factor, Ju, analogous to their Jh heat transfer (Sect. 4.4.4) [Pg.38]

The factor [B] im/[M], the logarithmic mean concentration of the inert component B divided by the total concentration, allows for the fact that the concentration of B may alter significantly. [Pg.38]

Other correlations for flow through packed beds involve the porosity, e, e.g. [Pg.39]

In all these expressions, Rep is the Reynolds number based on the particle diameter. [Pg.39]
