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.

Abstract: A soot sensor and method for detecting soot is provided. In one exemplary embodiment, a sensing element for a soot sensor is disclosed herein, the sensing element having a pair of peripheral edge sensing electrodes each having a portion disposed on a peripheral edge of a non-conductive substrate of the sensing element; a first pair of side sensing electrodes disposed on a first side of the sensing element, the first side having a first area partially bounded by the peripheral edge, wherein a resistance between the pair of peripheral edge sensing electrodes decreases as soot accumulates on portions of the pair of peripheral edge sensing electrodes and a resistance between the first pair of side sensing electrodes decreases as soot accumulates on portions of the first pair of side sensing electrodes.
