Further, the system includes a second scrubber with a top end and with a bottom end in fluid communication with the first scrubber's top end. During operation, exhaust gases are introduced into the bottom end of the first scrubber. Further, a light alcohol solvent is flowed down from the top end to the bottom end of the first scrubber. As the solvent contacts the exhaust gases, it absorbs the other organic carbons. Thereafter, the exhaust gases enter the second scrubber's bottom end. At the second scrubber's top end, water is introduced and falls into contact with the exhaust gases, absorbing the ethanol. In this manner, ethanol and other organic carbons are removed from the exhaust gases solely through absorption by solvents. | 06-03-2010 |
