Abstract:The basic principles of a steady-state mass transfer
model and
the resistance-in-series film model are assessed with the aid of a
series of experiments in a gas–liquid contact membrane mini-module
(3 M Liqui-Cel MM-1.7 × 5.5) using an aqueous solution of diethanolamine
(DEA) of 0.25 M (mol/L) for biogas upgrading. Experimental data show
that CO2 removal may exceed 67% and reach 100% in combination
with the highest possible recovery of CH4 when employing
biogas flow rates in the range of 2.8 × 10–5 – 3.6 × 10–5… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
