Thin Film Sulfonation of Dodecyl Benzene

Example 10.3.1 Thin-Film Sulfonation of Dodecyl Benzene [Pg.252]

The friction factor inside the tube with the falling liquid film may be calculated from [Pg.253]

SOLUTION Since the reaction between SO3 and DDB is instantaneous, the mass fraction of SO3 at the gas-liquid interface will be zero, that is, [Pg.253]

We proceed by evaluating the mass density of the gas mixture from = MP/RT [Pg.254]

Since the flux of nitrogen is zero we may evaluate the mass transfer rate factor directly as (cf. Eq. 8.2.18) [Pg.254]
