• Resumen

  • The paper is related to the development of a high performance BTF to control methanol and ethanol emissions. Removal efficiency was studied in terms of various operational parameters such as inlet concentration of alcohol and empty bed residence time (EBRT). For an EBRT of 65 s, removal efficiency attained 75% in a range of ethanol inlet concentration of 1200 to 8000 ppmv, and in a range of methanol inlet concentration of 400 to 6500 ppmv. These results show that BTF removal efficiency was not affected by VOC concentration at constant EBRT. On the other hand, the EBRT has a direct effect on removal efficiency. When BTF operated at an ethanol inlet concentration of 400 ppmv the removal efficiency was nearly 100 % for an EBRT in the range of 65 s to 130 s, and it was 75 % for an EBRT of 30 s. Carbon dioxide generation was also analyzed and correlated with BTF performance.
