Abstract
Channels with small hydraulic diameters are novel contactors that enhance mass transfer rate due to great interfacial area to
volume ratio and flow hydrodynamics. One of the interesting applications of small channels is gas absorption processes including
oxygen absorption, carbon dioxide capturing, methane and hydrogen sulfide absorption and volatile organic compounds (VOCs)
sequestration. This research presents a brief review on the recent developments and advances in application of Minichannels in gas
absorption process, flow hydrodynamics and mass transfer characteristics in Minichannels. The major studies have been conducted
on the CO2 capture and separation by aqueous solution of amines due to effect of CO2 emission on the global warming and popularity
of CO2 separation units. Although many researches have been conducted on gas absorption in mini contactors, there is a long way
to industrialize this technology.
