Question: Repeat the alternative solution to Example 2-4 but use 2-in. metal Pall rings. Example 2-4 A vertical flash drum is to flash a liquid feed

Repeat the alternative solution to Example 2-4 but use 2-in. metal Pall rings.

Example 2-4

A vertical flash drum is to flash a liquid feed of 1500

A vertical flash drum is to flash a liquid feed of 1500 lbmol/h that is 40 mol% n-hexane and 60 mol% n-octane at 101.3 kPa (1 atm). We wish to produce a vapor that is 60 mol% n- hexane. Solution of the flash equations with equilibrium data for YH = 0.60 gives XH = 0.19, Tdrum = 378K, and V/F = 0.51. What size flash drum is required?
