In this work, a comprehensive mathematical model was developed in order to evaluate the CO2 capture process microporous polypropylene hollow-fiber membrane countercurrent contactor, using monoethanolamine (MEA) as chemical solvent. terms of absorption, showed excellent agreement with experimental data published literature for wide range operating conditions (R2 > 0.96), 1–2.7 L/min gas flow ...

Conventional methods for improving the hydrophobicity of polypropylene (PP) membranes to prevent wetting phenomena require complex pretreatment procedures in order activate surface enabling reaction with fluorosilane (FS)-based materials. This study successfully prepared PP membrane contactors enhanced through a simple single-step dip-coating method using perfluoroether-grafted silanes CO2 capt...

Osmotic evaporation (OE) process is usually suggested to concentrate aqueous solutions. OE is a concentration technique based on the use of mesoporous or macroporous and hydrophobic membranes. The difference between the activity of solutions results in a pressure difference between the upstream diluted solution and the downstream (usually concentrated brine) solution. The latter generates a wat...

Efforts to increase the mass transfer coefficient, enhance the contact area, and decrease the power input of contractors have given risen to the development of the pre-dispersed solvent extraction (PDSE) contactor and the devise of the new dissolved nitrogen PDSE (DNPDSE) contactors. The studies conducted after the design of the new contactor to determine the working conditions for its suitable...
