RESUMO
Wet scrubbing is regarded as an effective method to remove hydrophobic organic odorants. The focus of wet scrubbing is to choose an appropriate scrubbing liquid. In this study, methyl mercaptan (CH3SH) was selected as a representative hydrophobic organic odorant for treatment by wet scrubbing using several types of scrubbing solution: ethanol (C2H5OH), lead acetate ((CH3COO)2Pb), sodium hypochlorite (NaClO), and sodium hydroxide (NaOH). A comparative analysis of the treatment efficiency, operation cost, and environmental impact was conducted. Results of the technical and economic comparison indicate that the C2H5OH solution is the best choice of scrubbing solution among those tested. These findings serve as a reference for engineering design and operation for the removal of hydrophobic organic odorants.
