Performance evaluation of mass transfer correlations in the GFMA process: a review with perspectives to the design
Gas filled membrane absorption process (GFMA), or hollow fiber gas membranes process (HFGM) can replace two units operations (absorption and stripping) in a unique stage based on membrane contactors. But its application ...
Characterization of chemical kinetics in membrane-based liquid-liquid extraction of molybdenum(VI) from aqueous solutions
This study aims to describe the mass transfer in a membrane-based solvent extraction system for the extraction of molybdenum(VI) from aqueous solutions, identifying chemical kinetics of the complex formation at the interface. ...
Separation of zinc ions from an acidic mine drainage using a stirred transfer cell-type emulsion liquid membrane contactor
This is a report on the separation and recovery of zinc ions from an acidic mine drainage using a stirred transfer cell-type emulsion liquid membrane contactor. Di(2-ethylhexyl) phosphoric acid was used as a highly selective ...
Assessment of industrial modules to design a GFMA process for cyanide recovery based on a phenomenological model
Cyanide recovery in the gold-mining industry is a crucial step in terms of the cost of operation. Currently, a process such as AVR (acidification, volatilization and recycling), based on packed towers for stripping and ...
