en عمومى General مقاله اصیل Original Article <div style="text-align: justify;">Background: The emission of aromatic compounds, particularly BTEX (benzene, toluene, ethylbenzene, and xylene), into the atmosphere poses significant environmental and health issues. Recognizing the limitations of traditional water-based scrubbing methods for hydrophobic compounds, this study aimed to determine the optimal conditions for absorbing BTEX compounds released during the frying process, using waste edible oil as an innovative absorbent in a packed scrubber system.<br> Methods: The effects of operating parameters such as scrubber bed height, frequency of oil reuse, and pollutant contact time on the removal efficiency and absorption capacity of BTEX were investigated through laboratory-scale experiments and gas chromatography analysis.<br> Results: The results showed that the removal efficiency of BTEX significantly improved with increased bed height from 64 to 98% for B, from 56 to 87% for T, from 36 to 59% for E, and from 58 to 89% for X. The results also showed a significant decrease in removal efficiency during absorption time. However, the removal efficiencies did not change significantly for all chemicals among the waste oils. The removal efficiency of B related to the use of oil ranged from 80 to 90%, from 63 to 87% for T, from 19 to 58% for E, and from 65 to 88% for X.<br> Conclusion: This research demonstrates the potential of utilizing waste edible oils in packed scrubbers for effective BTEX removal, highlighting the importance of optimizing operational conditions for improved air pollution control. The findings contribute to the development of more sustainable and environmentally friendly solutions for mitigating VOCs.</div> Benzene, Absorption, Volatile Organic Compound, Waste, BTEX 1 9 http://ehemj.com/browse.php?a_code=A-10-1-395&slc_lang=en&sid=1 Saeed Motesaddi Zarandi smotesaddi@sbmu.ac.ir 100319475328460020682 100319475328460020682 No Department of Environmental Health Engineering, School of Public Health and Safety, Shahid Beheshti University of Medical Sciences, Tehran, Iran Mohamadreza Massoudinejad massoudi2010@yahoo.com 100319475328460020683 100319475328460020683 No Department of Environmental Health Engineering, School of Public Health and Safety, Shahid Beheshti University of Medical Sciences, Tehran, Iran Ali Atamaleki Aliatamaleki69@yahoo.com 100319475328460020684 100319475328460020684 Yes Corresponding author: Department of Environmental Health Engineering, School of Public Health, North Khorasan University of Medical Sciences, Bojnurd, Iran Reihaneh Janipoor reihanehjanipoor1993@gmail.com 100319475328460020685 100319475328460020685 No Student Research Committee, School of Public Health and Safety, Shahid Beheshti University of Medical Sciences, Tehran, Iran Rajabali Hokmabadi abi.hse2006@gmail.com 100319475328460020686 100319475328460020686 No Department of Occupational Health Engineering, School of Public Health, North Khorasan University of Medical Sciences, Bojnurd, Iran Amir Mohammad Sheikh Asadi a.m.sheikhasadi@gmail.com 100319475328460020687 100319475328460020687 No Chair of Environmental Analytics and Pollutants, Institute IWAR, Technical University of Darmstadt, Darmstadt, Germany Elham Rahmanzadeh e.rahmanzadeh@gmail.com 100319475328460020688 100319475328460020688 No Student Research Committee, School of Public Health, Iran University of Medical Sciences, Tehran, Iran Mahdi Ghorbanian ghorbanian82@gmail.com 100319475328460020689 100319475328460020689 No Department of Environmental Health Engineering, School of Public Health, North Khorasan University of Medical Sciences, Bojnurd, Iran
