Abstract: Systems and methods for reducing a target molecule in a fluid are described. A fluid, such as a gas, may be contacted with a fluid capable of binding with the target molecules and removing the target molecules from the fluid. For example, emissions from a production process may be contacted with water to remove volatile organic compound (VOCs), thereby reducing the VOCs in the emissions. The fluid with bound target molecules may form a target fluid that may be discharged from the system or may be reused until the concentration of the target molecules in the target fluid reaches a threshold concentration. An illustrative production process is the fermentation of wine, which produces an off-gas that includes VOCs, such as ethanol. The systems and methods for reducing a target molecule may significantly reduce or even eliminate the amount of ethanol in the fermentation off-gas.
