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.

An apparatus for separating water from oil-based drilling fluid includes an separation tank, a chemical treatment apparatus having one or more de-oiling polymer preparation tanks, and a dissolved air flotation unit. Slop mud is directed into the separation tank where surfactant is added to separate the drilling fluid from oily water. The drilling fluid is drained for further processing. The oily water is removed by an outlet arrangement from the separation tank and directed to an initial treatment line. One or more de-oiling polymers are added to the oily water in the initial treatment line and mixed therewith. The mixture may then be directed to the dissolved air flotation unit where dissolved air is released into the bottom of the mixture. The dissolved air adheres to suspended solids in the mixture and lifts them to the top surface as a froth. The froth is skimmed from the top surface of the mixture and collected. The de-frothed water is reused or directed to a filtration system where it is prepared for discharge. A clarifying tank may be included after the de-oiling polymers are added to further separate the oil and water. The oil is removed from the top surface by a weir while the water is directed to the filtration system and discharged.

A fuel system for an energy conversion device includes a multiple of non-metallic fuel plates, gaskets, oxygen permeable membranes, porous substrate plates, and vacuum frame plates. Intricate 3-dimension fuel channel structures such as laminar flow impingement elements within the fuel channel dramatically enhance oxygen diffusivity in the FSU. The fuel plates are manufactured from a relatively soft non-metallic material. The non-metallic fuel plates and gasket arrangement provide an effective sealing interface between the fuel plate and oxygen permeable membrane, since compression may be applied to the plates without damaging the relatively delicate oxygen permeable membrane.

An elongated flow-through degassing apparatus includes an elongated gas and liquid impermeable outer member and a gas-permeable, liquid-impermeable inner barrier extending within the outer member and at least partially along a first chamber defined within the outer member. The apparatus also includes inlet and outlet connection structures operably coupled to respective portions of the outer member and a second chamber defined by the inner barrier to further enable a sealed engagement between the outer member and the inner barrier, and to provide for connection devices to operably couple the degassing apparatus of the present invention to respective spaced apart components. The degassing apparatus may be sufficiently flexible so as to be readily manipulatable into desired configurations.

A deoxygenator includes a plurality of permeable membranes spirally wound about an exhaust tube for removing dissolved oxygen from a hydrocarbon fuel. The permeable membrane is spirally wrapped about the exhaust tube and defines fuel passages and exhaust passages. The fuel passages and exhaust passages alternate such that each fuel passage is bounded on each adjacent side by an exhaust passage. An oxygen partial pressure differential is generated across the permeable membrane to draw dissolved oxygen from fuel in the fuel passage. The dissolved oxygen is then communicated through openings about the circumference of the exhaust tube and out the deoxygenator.

A liquid-dissolved gas separator includes a metallic separator. The separator has a plurality of open pores that connect a liquid-facing surface of the separator with an opposed vacuum-facing surface of the separator for separating dissolved gases from a liquid traversing the liquid-facing surface of the separator body.

A modular degassing device (40) is disclosed. The modular degassing device (40) comprises outer clamping plates (330, 340) with at least one degassing module (200) arranged therebetween, wherein the degassing module (200) comprises two modular plates (310, 320) adjacently arranged, both modular plates (310, 320) having a first channel on sides facing a membrane (46) placed therebetween, wherein the first channel of one modular plate (310, 320) is a fluid channel (224) on one side of the membrane (46), and the first channel of the other modular plate (310, 320) is a vacuum channel (212) on the other side of the membrane (46).
