The wet scrubbing process is commonly adopted for organic odor treatment. In this study, methyl mercaptan (CH3SH) was selected as a representative hydrophobic organic odorant which was treated using an ethanol solution in a scrubbing tower. Results showed that the ethanol solution can retain the ideal CH3SH removal effect for 2.0 h. The following experimental conditions were set: intake load of 4,700 m3 m−2 h−1, spraying load of 5,100 L m−2 h−1, and volume ratio of ethanol/water at 1:5. The solute accumulation of CH3SH in the scrubbing liquid exceede...
