Abstract: Disclosed herein is a spray nozzle comprising an annular head, a hollow neck, and a liquid inlet line disposed in the hollow neck. The annular head comprises a liquid inlet orifice, first and second external flow diversion surfaces, an interior circumferential channel, and an ejector. The ejector comprises a substantially smooth surface having a fixed width, the ejector extending from the point of contact with the interior circumferential channel such that in the extending direction, the substantially smooth surface increases in distance from the interior circumferential channel. Also disclosed herein is an apparatus comprising at least one such spray nozzle, and processes comprising using at least one such spray nozzle.

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.
