Abstract: Disclosed are methods, materials, apparatus and systems for removing or suppressing ambient levels of reactive gas contaminants, particularly acidic gases, using particles of zeolite, sepiolite or other suitable carrier material impregnated with at least one treatment compound selected to react with the acidic gas(es). The methods involve contacting a contaminated gas stream with the impregnated carrier materials whereby at least a portion of the reactive gases contacts the treatment compound and reacts, thereby consuming the reactive gas molecules.

Abstract: Methods and systems are disclosed for analyzing and treating a fluid containing a peroxyacid and/or peroxide. A method of analyzing the fluid includes introducing into the fluid a decomposition agent that catalyzes decomposition of the peroxyacid and/or peroxide into decomposition products including oxygen, then directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent, and determining an amount of the peroxyacid and/or peroxide present in the fluid. The amount of peroxyacid and/or peroxide in the fluid can also be monitored and controlled by further adjusting the amount of the peroxyacid and/or peroxide in the fluid based on the determined amount thereof. A system for performing the methods includes a decomposition agent infusion device for introducing the decomposition agent into a fluid sample, and a sensor for directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent.

Abstract: Compositions and methods for preventing corrosion of equipment having a corrodible metal surface that contacts water in a hydrostatic system are provided. Compositions may include a liquid-phase corrosion inhibitor and vapor-phase corrosion inhibitor. Methods may include introducing into the hydrostatic system a liquid-phase corrosion inhibitor, vapor-phase corrosion inhibitor and/or a scaling inhibitor. A protective film can be formed on the corrodible metal surface.

Abstract: Multiple chemical tracers are provided in a fluid system, and measured to evaluate parameters of the system. The multiple chemical tracers include at least one reactive chemical tracer that provides a measurable signal with an intensity that changes as the reactive chemical tracer reacts in the fluid system. The signals of the multiple chemical tracers are compared to each other to evaluate a system parameter, such as temperature, pH, or system events.

Abstract: Methods and systems for producing high purity gaseous chlorine dioxide are provided. A solid chlorite reactant is contacted with an ozone-containing reactant gas, or a gas containing both ozone and a component that reacts with any hydroxide byproduct (such as carbon dioxide), to produce chlorine dioxide. The reaction can be monitored and controlled to ensure that excess chlorite reactant is provided and to prevent ozone from passing into the product gas.

Abstract: There is provided methods for separating a target material from a raw material by mixing the raw material with water to form a slurry, adding a collector compound to the slurry to modify a relative hydrophobicity of a surface of the target material, adding a facilitator compound to enhance the modification of the relative hydrophobicity of the surface, and forming a froth including a concentrate of the target material. Disclosed methods may also include adding a facilitator compound to a raw material slurry that has been treated with a collector compound and a reagent for neutralizing the collector compound.
