In this work, 4-diethylamino-2-butanol (DEAB) as a new type of alkanolamine solvent is used for CO 2 capture in hollow fiber membrane contactor (HFMC). A model describing the gas and liquid reactions transport inside under wetting or non-wetting conditions was built. The countercurrent flow natural considered model. To investigate influence on decarburization efficiency, DEAB compared with othe...

membrane assisted liquid extraction(male) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. the present contribution outlines the classification of membrane assisted ...

We describe a new on-line sensitive and selective procedure for the determination of trivalent hexavalent chromium in liquid samples by tailor-made contactor (TMC), specifically membrane annular TMC, coupled with inductively plasma optical detection. The TMC was designed developed to integrate extraction stripping phases analyte one module minimize solvent’s consumption maximize speed transport...

Membrane gas–liquid contactors have been developed to reduce the capital cost and energy consumption of conventional CO2 absorption stripping columns. As a hybrid technology membrane separation amine absorption, these units can improve gas process by generating 400–1500% greater mass transfer area per unit volume leading smaller equipment sizes. Regeneration occur within contactor below boiling...

A tubular porous borosilicate membrane contactor was investigated for ozone gas/water mass transfer and the removal of contaminants emerging concern (CECs) in water. Ozone contact occurs on shell-side, which is coated with a photocatalyst (TiO2-P25), as gas stream fed from lumen side permeates through pores generating micro-sized bubbles uniformly delivered to annular reaction zone where contam...

The improvement of an innovative dual membrane contactor process for treatment of combined hygiene and metabolic wastewater was investigated. Flux and solute rejection in the combined direct osmosis/osmotic distillation (DO/OD) process were enhanced by incorporating membrane distillation (MD) concepts into the process. Two new configurations were investigated: DO/MD, in which the driving force was
