APPARATUS AND METHOD FOR TREATMENT OF VOLATILE ORGANIC COMPOUNDS IN AIR EMISSIONS PRODUCED DURING FERMENTATION PROCESSES

摘要

An apparatus for treating volatile organic compounds produced during a fermentation process is provided. The apparatus includes a ClO2 generator exhausting a ClO2 gas stream, a batch tank fluidly connected to the ClO2 generator outlet and receiving the ClO2 gas stream from the ClO2 generator outlet, the batch tank comprising an inlet for introducing a water stream and an outlet for exhausting an aqueous ClO2 solution from the batch tank, the aqueous ClO2 solution having a concentration of about 3000 mg/L, and a yeast product fermentation vessel configured to receive yeast product and the aqueous ClO2 solution from the batch tank and to ferment the yeast product and the aqueous ClO2 solution. Fermenting the quantity of yeast product and aqueous ClO2 solution reduces concentration of volatile organic compounds produced.
