Temperature and air–water ratio influence on the air stripping of benzene, toluene and xylene

摘要: Volatile organic compounds in water and wastewater can be removed using air stripping. The effects of temperature air-water ratios on the stripping benzene, toluene xylene (BTX) from have been examined at a range 30–50°C 20–100. Removal efficiencies >99%, >93% 93% for BTX, respectively, were obtained 50°C 100. removal increase non-linearly with flow ratio. increasing efficiency found to more significant temperatures between 30 35°C than 45 50°C. water-air 20–60 80–100. results indicate that high BTX achieved by operating stripper conditions even relatively low vice versa.
