Axial variation of wetting efficiency and liquid-solid mass transfer in long trickle bed columns

Du Toit, Elizabeth Louisa; Joubert, Rita; Saayman, Francois; Nicol, Willie (American Chemical Society, 2014-01)

The wetting efficiency and solid liquid mass transfer coefficient was measured separately and simultaneously using the electrochemical cell technique while varying the superficial liquid velocity and hydrodynamic state ...
Liquid–solid mass transfer distributions in trickle bed reactors

Nicol, Willie; Joubert, Rita (Elsevier, 2013-08)

Micro-electrodes with exposed areas ranging from 5-30 mm2 were placed onto 4.5 mm alumina spheres and used for the sub-particle scale quantification of liquid-solid mass transfer. A novel electrochemical technique was ...
Trickle flow liquid-solid mass transfer and wetting efficiency in small diameter columns

Joubert, Rita; Nicol, Willie (Wiley-Blackwell, 2013-03)

A novel method to simultaneously measure liquid-solid-mass-transfer and external wetting efficiency was employed at column to particle ratios of 10, 6 and 3. Two prewetting procedures representing the upper (Kan) and ...
