Question:
Suppose in Example 13-7 that we decide to build the settler with a diameter of \(1.0 \mathrm{~m}\) and a length of \(4.0 \mathrm{~m}\). What safety factor are we employing?
Example 13-7
Transcribed Image Text:
Design a baffled mixing vessel and a horizontal settler for extraction of benzoic acid from water (diluent) into toluene (solvent). The mixing tank (Figure 13-31) should have H/dtank = 1.0, and there should be a 1-in. (0.0254 m) head space (vapor space at top). The flow rate of the aqueous feed is 0.006 m/s, and the volumetric solvent-to-feed ratio = 0.2. A six-blade flat turbine impeller with impeller diameter d; = 0.25 dank and impeller width w =d/5 is operated at 1000 rpm. Simple settling experiments show that this is a type I (rapid settling) system. A. For a mixture residence time of 1.0 minutes, find the mixer dimensions and estimate the volume fraction of the dispersed phase and power P required. B. Set L/dsettler = 4, and use Stokes law to size the horizontal settler.
