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

在连续模式下运行的设施中通过电洗涤去除甲苯，比较填充柱和喷射电洗涤系统在吸收剂中的保留和电化学降解方面的性能。发现气流携带的约一半甲苯仅通过吸收保留。填充柱电洗涤器在电化学降解方面表现出更好的性能，而喷射混合装置显示出最高浓度的甲苯保留在电解质/吸收剂中，达到过饱和水平。气流的流速对电洗涤系统的效率有很大影响：塔在较低流速下效率更高，而喷射洗涤器在较高流速下效果更好。检测到工业溶剂中夹带的物质（主要是 2-甲基苯酚和 4-甲基苯酚），它们被有效降解。苯甲醛和苯甲酸被检测为中间体。
