however, to obtain an approximate indication of the rate of transfer from the particles to the bulk of the liquid. Using the concept of a thin film as providing the resistance to transfer, the equation for mass transfer may be written as: (A) Leaching: N A = D AL b C S −C = K L C S −C N A = K L.A C S −C N A = kmol s = dM dt dM dt = K L.A C S −C M = C V

Example 9 5. Distillation of Benzene, Toluene, and Xylene

A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottom product contains 98.0 mole% X and no B, and 96.0% of the X in the feed is recovered in this stream. The overhead product is fed to a second distillation column.

CHAPTER 11 Separation Columns (Distillation, Absorption

Three principal types of cross-flow tray are used, classified according to the method used to contact the vapour and liquid. 1. Sieve plate (perforated plate) (Figure 11.18) This is the simplest type of cross-flow plate. The vapour passes up through perforations in the plate; and the liquid is retained on the plate by the vapour flow.

1. Distillation usually is the most economical method of separating liquids, superior to extraction, adsorption, crystallization, or others. Exceptions to this rule include: Flash separation when flash separation is sufficient and Settling (decanting or coalescing) when the mixture has LL immiscibility without addition of extraction solvent. 2.

Computing the steady states of the counter-current multistage processes is equivalent to finding solutions of large scale non-linear equation systems.
