摘要： A dual-pathway system for CO2 capture in both acidified and basified streams is provided. The system may be embodied in an off-shore stand-alone facility to allow for the operation of oceanic CO2 capture to be more efficient and cost effective. Systems maintain high environmental standards by containing all intermediate acidic and alkaline solutions in a closed system so that the effluent discharged back into the ocean is at the similar pH and salinity as the feed oceanwater, with only CO2 removed. Acid and base produced by an electrodialyzer unit is used to achieve oceanwater decarbonization via gaseous CO2 removal and solid CaCO3 precipitates removal. The system is configured to require the processing of a very small fraction of the total oceanwater intake for the acid-base generation process.

摘要： A membrane is described for purifying or separating hydrogen from a multi-component gas stream such as syngas. This membrane uses a molecular pre-treatment, a transition metal, fluorine containing polymer, carbon fibers and carbon matrix sintered on a supportive screen. The membrane may be a bilayer membrane comprised of a layer containing high surface area carbon and another layer containing lower surface area carbon. Methods for purifying hydrogen are also described.

摘要： A filtration device containing a porous polyparaxylylene (PPX) filtration article is provided. The PPX filtration article includes at least one PPX polymer membrane layer and one or more substrate. Optionally, the PPX filtration article may include one or more support layer(s). The PPX polymer membrane has a pore size from about 1 nm to about 100 nm. The filtration article has a PVA_20 less than about 0.6 cm3/m2 and/or a mass/area (MPA) less than about 30 g/m2. The PPX filtration article separates and retains nanoparticles from a feed fluid with high permeability. In use, the PPX filtration article filters nanoparticles from a feed flow by passing the feed fluid through at least one PPX polymer membrane within the filtration article where the nanoparticles are separated and removed from the feed fluid. The PPX polymer membranes may be resistant to chemical attack, gamma radiation, and are thermally stable, biocompatible, and strong.
