Experimental Measurement of Membrane Residue Curve Maps
Membrane residue curve maps (M-RCMs)
are a useful graphical tool
developed to better understand and design membrane separations [Peters, M.; Kauchali, S.; Hildebrandt, D.; Glasser, D. Ind. Eng.
Chem. Res. 2006, 45, 9080]. The maps, initially
developed theoretically, track the compositional change of the retentate
with time during batch permeation. This article looks at the design
and construction of an experimental apparatus for the measurement
and existence of M-RCMs. For demonstration purposes, gas separation
was chosen for the basis of the membrane separation system. The gas
mixture, which consisted of syngas with carbon dioxide as an impurity,
was passed through a polyethylene membrane. The theoretical
transport of gases moving through the membrane was developed by a
solution diffusion model that fitted the experimental system adequately.
The experimental setup was successfully designed and operated; the
results obtained correlate to the theoretical models chosen. In addition,
the experimental apparatus can be used for the validation of M-RCMs
for any type of membrane and mixture of gases
