Comparison of the performance of packed column and jet electro-scrubbers for the removal of toluene

Toluene removal by electro-scrubbing was carried out in facilities that operate continuous mode, comparing the performance of packed column and jet electro-scrubber systems, both terms retention absorbent electrochemical degradation. It found about half toluene air flow is retained only absorption. The showed better degradation, while mixing device highest concentrations electrolyte/absorbent, reaching levels supersaturation. rate gas stream has a great influence on efficiency system: appears to be more efficient at lower rates scrubber works higher rates. Entrained species industrial solvent were detected (2-methylphenol 4-methylphenol, principally) efficiently degraded. Benzaldehyde benzoic acids as intermediates. • Jet devices allow toluene. Higher than jet-scrubber system low capacity concentrate absorbent. Other impurities real effluents also
