Influence of current density and inlet gas flow in the treatment of gaseous streams polluted with benzene by electro-absorption

•Efficient mineralization of the VOCs contained in the air using electro-scrubbing technology.•Benzoquinone and carboxylic acids are formed in the absorbent but not found in the outlet stream.•Percentage of benzene gaseous removal increases by increasing operation current density.•Mass transport control of the electrochemical degradation of benzene into the absorbent/electrolyte.
