Abstract:
A sorbent, suitable for removing heavy metals, including mercury, from fluids containing hydrogen and/or carbon monoxide at temperatures up to 550° C., in the form of a shaped unit comprising one or more mixed-valency metal sulphides of vanadium, chromium, manganese, iron, cobalt or nickel.
Abstract:
In a regenerative dialysis system, in a method for controlling a regenerative dialysis system, and in a controller for a regenerative dialysis system, an embodiment of the system comprises an input pump that pumps fresh dialysate fluid into a dialyzer at an input rate. An output pump pumps used dialysate fluid from the dialyzer at an output rate. An ultrafiltration rate of the system is related to the output rate relative to the input rate. A sorbent cartridge filters the used dialysate fluid to generate the fresh dialysate fluid. A controller controls the ultrafiltration rate of the system in response to a flow rate of the dialysate fluid through the sorbent cartridge.
Abstract:
Rare earth metal compounds, particularly lanthanum, cerium, and yttrium, are formed as porous particles and are effective in binding metals, metal ions, and phosphate. A method of making the particles and a method of using the particles is disclosed. The particles may be used in the gastrointestinal tract or the bloodstream to remove phosphate or to treat hyperphosphatemia in mammals. The particles may also be used to remove metals from fluids such as water.
Abstract:
Method of reducing the concentration of sulfur and/or a sulfur-containing compound in a biochemically prepared organic compound by bringing the respective organic compound into contact with an adsorbent, wherein the adsorbent is a clay doped with silver and/or a silver compound.
Abstract:
A method of forming an agent for removing or separating a species from a diluent or process stream, e.g. a desulphurisation agent. The method comprises mixing at least one compound of manganese and pore forming articles.
Abstract:
A lamp assembly including at least one light source, a housing formed from a first moisture barrier composition and a sealing cap formed from a second moisture barrier composition, wherein the at least one light source is arranged within the housing and the sealing cap is hermetically bonded to the housing and the at least one light source, and the sealing cap is arranged to enclose the at least one light source within a volume formed by the housing and the sealing cap.
Abstract:
The invention relates to a composite material, a method for controlling the thermal effects generated in a physicochemical process using said material, and applications of the material and the method.The composite material comprises an active solid and a phase change material. The phase change material takes the form of micronodules having an average size of between 1 micron and 5 millimeters and it is selected from materials with a liquid/solid phase change temperature of between −150° C. and 900° C. The active solid is selected from solids that can be used in a method involving reversible physicochemical processes that are exothermic in one direction and endothermic in the opposite direction.

Abstract:
Finely divided ferrous carbonate absorbent, siderite granules or absorbent particles made by mixing, agglomerating and shaping finely powdered ferrous carbonate, preferably siderite, in combination with minor effective amounts of water or an optional binder, followed by drying, are used to treat and significantly reduce concentrations of hydrogen sulfide, carbonyl sulfide, organic disulfides, mercaptans and other sulfurous compounds and contaminants in gaseous and liquid fluid streams such as natural gas, light hydrocarbon streams, crude oil, acid gas mixtures, carbon dioxide gas and liquid streams, anaerobic gas, landfill gas, geothermal gases and liquids, and the like. Methods for absorbing sulfur compounds in a moist atmospheric environment and for regenerating the absorbent by contacting it with air and steam or, continuously, by mixing the feed stream with moist air are also disclosed.
