An oil-water mixture from a pilot-plant reactor is separated in a horizontal decanter 0.6 m in diameter

Question:

An oil-water mixture from a pilot-plant reactor is separated in a horizontal decanter 0.6 m in diameter and 3 m long. The residence time needed in the decanter is found to be 20 minutes.

(a) If a large unit is designed to handle 12 times the flow rate, what would be the dimensions of the large decanter?

(b) Comment on the use of Eq. (2.15) for scaleup, considering the settling velocity of the smallest droplets.

Eq. 2.15

1= 100 PA-PB (2.15) where

t = separation time, h

ρ_A, ρ_B = densities of liquids A and B, kg/m³

μ = viscosity of the continuous phase, cP
