Answer 1

The correct option is (d) Droplet size, droplet size distribution and axial dispersion

To explain: The main factors considered for the operation of extraction column are droplet size, droplet size distribution and axial dispersion. Axial dispersion follows from different phenomena like turbulence or differences in the droplet sizes, and results in lower column efficiency.
