A device and methods related to the same are provided for the treatment of exhaust gases. An exhaust gas treatment device is provided comprising a tank, a liquid bath, and a scrubber unit, the exhaust gas being passed through the liquid bath to treat the gas of exhaust products and through a scrubber unit to scrub the treated gas and remove any entrained bath therefrom on a plurality of condensing surfaces. The condensate of entrained gas may be collected and recirculated to the liquid bath in the tank. The exhaust gas may be delivered to the tank for passing it through the liquid bath and through a filter for the removal of exhaust products prior to being expelled through an exhaust port into the atmosphere. The liquid bath may comprise a solution of one or more organic solvents selected to configure the bath to remove exhaust products as desired.
