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...
A cascade crosscurrent column, packed with Pall rings, was employed
for ammonia absorption from ammonia-rich air phase by
contacting with water. Absorption efficiency was presented as
the percentage of NH₃ removed as well as the volume of a transfer
unit.
A review of the literature concerning the theoretical and experimental...
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 complete solution, exact to second-order, for wave motion
forced by a hinged-wavemaker of variable-draft is presented. A
solution for a piston type wavemaker is also obtained as a special
case of a hinged-wavemaker with negative infinite draft. The
existing Stokes inviscid theories for mass transport is extended to
include...
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...
The surface renewal rate from Danckwerts' theory and
the effective interfacial area between gas and liquid per
unit packing volume in a packed absorption tower were
evaluated for the absorption of carbon dioxide into
carbonate/bicarbonate buffer solution accompanied by a
pseudo-first order chemical reaction. The rate of chemical
reaction in...
