A steady-state, liquid-liquid contactor, which was a
modified version of a cell Previously developed by Godfrey,
was constructed for the study of interphase mass transfer.
In particular, the contactor was developed in order to
eliminate problems encountered while studyinpg ternay
systems with the conventional Lewis cell.
The system, water-benzoic acid...
A cascade crosscurrent column, packed with Pall rings, was
employed for carbon dioxide absorption from a carbon dioxide-rich
air phase by contacting with water. Absorption efficiency was
presented as the percentage of CO₂ removed versus gas flow rates for
constant liquid to gas ratios (L/G).
Curves were developed for an...
Public concern has recently focused upon the presence
of radioactive radon in homes. The Environmental
Protection Agency and others have researched this health
hazard. Radon gas is given off during typical household
water uses such as showering, bathing, dishwashing, and
clothes washing. However, few studies have been performed
on radon...
A contactor has been designed and constructed for experimental
studies of mass transfer with or without chemical reaction between
two fluid phases. The contactor is flexible enough to investigate a
wide range of variables affecting mass transfer coefficients. It is
easy to operate; it could be operated either as a...
A direct numerical simulation of advection-diffusion in a sinusoidal tube was
carried out using the commercial finite-volume code STAR-CD. The Reynolds
numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers,
steady-state eddies formed in the diverging sections and significantly influenced
the macroscale dispersion. Long...
The parallel implementation of a large number of functional units is necessary for
any industrial scale microfluidic process. The concept of a 'numbering up'
strategy where a single highly optimized functional unit that has a low individual
production is replicated a large number of times to create a device that...
