Abstract: A scrubber system for cleaning exhaust gas from different engines. The scrubber system includes a scrubber, such as a wet scrubber, for removing a constituent from the gas and a housing having an inlet for receiving the gases into the scrubber and an outlet for discharging cleaned gas. An exhaust mixer has plural inlets for receiving exhaust gas from the different engines and an outlet for discharging the gases into the scrubber through the inlet. The exhaust mixer mixes the exhaust gases into a combined flow stream exiting the exhaust mixer outlet. The scrubber system can clean exhaust gases from different engines by connecting exhaust pipes from each engine to a respective inlet, mixing the exhaust gases in the mixer, and directing the mixed gases into the scrubber, which cleans and discharges the cleaned, mixed gases. The scrubber system can be provided to a marine vessel.

Abstract: A reactor can apply a reactant to a gas flow that is conveyed through a vessel. The vessel has an inlet and an outlet for receiving and discharging, respectively, this gas flow. Also included is a spray nozzle mounted in the vessel for spraying the reactant therein at a given flow rate. The reactor also includes a horn mounted in the vessel for acoustically vibrating the reactant at an energy level sized to evaporate the reactant substantially completely, prior to reaching the outlet.
