Fluid flow and mass transfer characteristics of enhanced CO2 capture in a minichannel reactor

Hydrodynamics and mass transfer performance of a microreactor for enhanced gas separation processes

“…1. A detailed description of the same was previously reported by the authors in Ganapathy et al [62], and key details are provided here. A Tjunction type of inlet configuration was utilized to inject the gas and liquid phases into the test section.…”

“…Both works reported various performance parameters including the absorption efficiency, pressure drop, mass transfer coefficient, interfacial area, and Sherwood number. Further, Ganapathy et al [62] studied the effect of channel length and proposed a two-phase frictional pressure drop model for amine-based working fluids. The effect of system pressure on mass transfer was investigated by Ye et al [63] for the absorption of CO 2 mixed with N 2 in methylethanolamine (MEA) in a 408 lm minichannel.…”

“…Ganapathy et al [62] studied the absorption of CO 2 mixed with N 2 into aqueous DEA in a 762 lm channel. Both works reported various performance parameters including the absorption efficiency, pressure drop, mass transfer coefficient, interfacial area, and Sherwood number.…”

Hydrophobic fluorocarbon-modified silica aerogel tubular membranes with excellent CO2 recovery ability in membrane contactors

“…As a result, CO 2 gases pass through the membrane pore and are absorbed by the aqueous amine solution. As a result, a variety of hydrophobic polymeric membranes, such as polypropylene (PP) [1][2][3][4], polyphenylsulfone [5], polyvinylidene difluoride (PVDF) [6,7] and polytetrafluoroethylene (PTFE) [8,9], have been used in membrane contactors for CO 2 capture. However, these polymeric membranes are easily swelled by the aqueous amine solution to change their surface morphology and roughness, leading to a decrease in the CO 2 absorption capacity.…”

Experimental study of two-phase flow in a proton exchange membrane fuel cell in short-term microgravity condition

“…The two-phase flow inside PEMFCs has a significant impact on reactant transport [12][13][14], e.g., transport limitation. Visualization method is an effective way to observe the two-phase flow, which has been used for tube [15] or minichannel [16] recently. Researchers have studied the two-phase flow caused by liquid water inside PEMFCs by using the direct visualization method and transparent PEMFCs [17][18][19][20][21][22][23][24][25][26][27].…”
