Electrochemical membrane flue‐gas desulfurization: K₂SO₄/V₂O₅ electrolyte

Abstract

The viability of a new electrolyte was demonstrated in the bench

Regenerating flue‐gas desulfurizing agents by bipolar membrane electrodialysis

“…Up until now, many categories of flue‐gas desulfurizing methods have been developed. Some of these categories are wet sorption, dry sorption, catalytic oxidation,2 electrochemical membrane conversion,3, 4 and RF‐plasma conversion 5. In comparison with other flue‐gas desulfurization processes, wet sorption processes are preferentially applied.…”

Paired Electrochemical Processes: Overview, Systematization, Selection Criteria, Design Strategies, and Projection

“…Problems involving slow kinetics and abundant sludge generation have promoted the search for alternative remediation methods. Electrochemical schemes have been developed based on the direct or indirect anodic oxidationof SO 2 (g) to SO 4 2-(which in acidic media forms H 2 SO 4 ) or its reduction into elemental S(s); the paired reduction of water produces useful H 2 (g) [95,[97][98][99][100][101]. In another example, organic textile dye effluents are anodically degraded with the paired cathodic generation of NaOH [49] or H 2 (g) production [102] in an electrochemical membrane cell.…”
