4. Solving the equations simultaneously. D = 71, B = 129. step 2 Set vapor and liquid flow in the column.

1. Find L from the definition of reflux [Eq. (2.16)]

Figure 2.9 Solution to Example 2.1. (o) Steps 1, 2; (b) step 3; 4c) step 4.

Figure 2.9 Solution to Example 2.1. (o) Steps 1, 2; (b) step 3; 4c) step 4.

3. Since 25 percent of the feed is vaporized, q = 0.75, Find L' from the definition of q, Eq. (2.28)

V = L' - B = 363 - 129 = 234 lb-mole/h The materia] balances and flows are shown in Fig. 2.9a.

step 3 Establish component balance and g-lines. Use the equations in Table 2,3.
