    摘要: Process for fabricating a catalyzed ion transport membrane (ITM). In one embodiment, an uncatalyzed ITM is (a) contacted with a non-reducing gaseous stream while heating to a temperature and for a time period sufficient to provide an ITM possessing anion mobility; (b) contacted with a reducing gaseous stream for a time period sufficient to provide an ITM having anion mobility and essentially constant oxygen stoichiometry; (c) cooled while contacting the ITM with the reducing gaseous stream to provide an ITM having essentially constant oxygen stoichiometry and no anion mobility; and (d) treated by applying catalyst to at least one of (1) a porous mixed conducting multicomponent metallic oxide (MCMO) layer contiguous with a first side of a dense layer of MCMO and (2) a second side of the dense MCMO layer. In another embodiment, these steps are carried out in the alternative order of (a), (d), (b), and (c).

    摘要: The invention relates to the treatment of water, including for example treatment in connection with hydrocarbon production operations. Silica in water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature may be combined with a process of ceramic ultra-filtration (UF filtration) employed to treat water, and optionally followed by any of membrane distillation or forward osmosis (FO). Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The treatment units (e.g., EC, forward osmosis, UF filtration, etc) can be configured into one system as an on-site installation or a mobile unit for on-site or off-site water treatment.
