A device for treating at least a portion of the exhaust fumes emitted by at least one fuel-consuming apparatus, the treatment device includes at least one compression member designed to raise a pressure of at least a portion of the exhaust fumes emitted by the fuel-consuming apparatus, and at least one unit for capturing carbon dioxide present in the exhaust fumes, the compression member and the unit for capturing carbon dioxide being arranged between the fuel-consuming apparatus and a turbocharger, a turbine of which is designed to be powered by the exhaust fumes and a compressor of which is designed to supply the fuel-consuming apparatus with oxidizer.

The present disclosure is directed to an emission treatment system for NO.sub.x abatement in an exhaust stream of a lean burn engine. The emission treatment system includes a lean NO.sub.x trap (LNT) in fluid communication with and downstream from the lean burn engine and a low-temperature NO.sub.x adsorber (LT-NA) in fluid communication with and downstream of the LNT. Further provided is a method for abating NO.sub.x in an exhaust stream from a lean burn engine utilizing the disclosed system.

A porous ceramic honeycomb body including a substrate of intersecting porous walls forming axial channels extending from a first end face to a second end face. An active portion of the walls include a zeolite catalyst disposed inside pores thereof and/or is comprised of an extruded zeolite and a three way catalyst (TWC) is disposed on wall surfaces of at least a portion of the active portion.

Exhaust purification system and methods for the reduction of emissions from an exhaust stream, including an upstream catalyst coupled with a passive NO.sub.x adsorber catalyst; means to contact the exhaust stream with ozone, to react NO in the exhaust stream with the ozone to produce NO.sub.2; and an SCR catalyst.

A method for reducing the level of occluded alkali metal cations from an MSE-framework type molecular sieve comprises either (a) contacting the molecular sieve with a solution containing ammonium ions at a temperature of at least about 50 C. to ammonium-exchange at least part of the occluded potassium ions or (b) contacting the molecular sieve with steam at a temperature of at least about 300 C. and then subjecting the steamed molecular sieve to ammonium exchange.

An air dryer includes a supporting base, a drying agent container, and an outer cover. The supporting base includes an inlet for receiving compressed air to be subject to a drying process and an outlet for delivering the processed compressed air that has undergone the drying process. The drying agent container is a container supported on the supporting base, contains a drying agent in the interior, and enables the drying process to be performed by passing the compressed air from the inlet through the drying agent. The outer cover surrounds the outer side of the drying agent container on the supporting base and defines a chamber for storing the compressed air between itself and the drying agent container. The supporting base includes first and second mounting surfaces, which are oriented in different directions, and a plurality of inlets, which are oriented in different directions and receive the compressed air.

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.
