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.
