Provided is an emission treatment system and method for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The emission treatment system has an oxidation catalyst upstream of a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia. Also provided is a method for disposing an SCR catalyst composition on a wall flow monolith that provides adequate catalyst loading, but does not result in unsuitable back pressures in the exhaust.

The present invention generally offers a system and a method that allows a vessel to treat water while providing corrosion inhibition. An oxygen stripping gas source produces oxygen stripping gas that may be pumped directly to, preferably but optionally, a venturi injector, or may first be pumped into an empty tank and then delivered to the injector means. Water being pumped through the injector via a transfer piping means comes into contact with the oxygen stripping gas, and dissolved oxygen in the water transfers to micro-fine stripping gas bubbles generated by the injector. The water and the micro-fine bubbles are pumped from the injector and into the tank, where the micro-fine bubbles float to the surface, and the oxygen is released into the tank's headspace. The deoxygenated water may be re-circulated through the system for additional deoxygenation or released from the tank into the surrounding waterways.

The invention relates to a method for continuously deaerating a liquid. The method comprises the step that the liquid is led into a closed container (1) so that a liquid surface (7) is formed within the container (1). The space above the liquid surface (7) is under vacuum. The method further includes the step that a gas is led into the liquid at a level below the liquid surface (7). The invention also relates to an apparatus which comprises a closed container (1). The container (1) has an inlet (5) for the liquid which is to be deaerated, as well as an outlet (6) for the liquid which has been deaerated, both placed in the lower region of the container (1). The container (1) further has a connection (13) to a vacuum pump (14) placed in the upper region of the container (1), as well as an inlet (15) for a gas placed in the lower region of the container (1).

An aircraft fuel deoxygenation and tank inerting system includes an inert gas source, a fuel deoxygenation system, and an air / fuel heat exchanger. The inert gas source is configured to supply inert gas having an oxygen concentration of less than 3%. The fuel deoxygenation system is adapted to receive fuel from a fuel source and the inert gas from the inert gas source. The fuel deoxygenation system is configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel and oxygen-rich purge gas. The air / fuel heat exchanger is adapted to receive compressed air from a compressed air source and the deoxygenated fuel from the fuel deoxygenation system. The air / fuel heat exchanger is configured to transfer heat from the compressed air to the deoxygenated fuel, to thereby supply cooled compressed air and heated deoxygenated fuel.

A tank is fed with mud via a first inlet and the mud is removed via a first outlet. An ultrasonic electroacoustic transducer generates an acoustic energy field in the mud contained in the tank so as to extract the gases from the mud. A carrier gas is injected via a second inlet of the tank and a physico-chemical analysis apparatus of the extracted gases is connected to a second outlet of the tank designed for the carrier gas and the extracted gases. The flow rate of mud fed to the tank is regulated to a constant value and the volume of mud in the tank is constant. The mud can be constituted by oil prospecting drilling mud, the gases to be extracted then being oil revealing gases. The mud feed and injection of carrier gas can be synchronized so as to enable continuous analysis or batch analysis.

A system and method are disclosed for purifying a waste fluid stream. The system includes a recirculation pump having an inlet for a recirculation stream and an outlet to expel a pressurized stream. The system includes a compressor having an inlet for an evaporation stream and an outlet for a pressurized evaporation stream. A primary heat exchanger has inlets for the pressurized stream and the pressurized evaporation stream, an internal surface area for heat transfer from the evaporation stream to the pressurized stream, and outlets for a cooled product stream and a heated pressurized stream. The heated pressurized stream is formed by heating the pressurized stream and the cooled product stream is formed by cooling the evaporation stream. The system includes an evaporation unit having an inlet for the heated pressurized stream and outlets for an evaporation stream and the recycled liquid bottoms stream.
