Disclosed is a bypass system for use with off gases that have exited a cement kiln utilized in a cement making process. The bypass system is adapted to remove both NOx and volatile components that are present in the off gases while the off gases are in the bypass duct.

The present application provides a method of treating flue gas in a duct with an injection system, the flue gas comprising an acid gas and/or one or more metal components, the injection system comprising at least one injection nozzle in communication with an air supply and a supply of sorbent; wherein the method comprises supplying air and sorbent through the nozzle to the duct such that the penetration of the sorbent into the duct is represented by the formula: Y=(D.sub.na(p.sub.nV.sub.n.sup.2/p.sub.fV.sub.f.sup.2).sup.0.5(x/D.sub.n).sup.0.33)/D.sub.f where Y is the fraction of duct penetration depth of the sorbent when the duct length is x, D.sub.n is the diameter of the nozzle, D.sub.f is the depth of the duct, p.sub.n and p.sub.f are the densities of the air supply and flue gas, respectively V.sub.n and V.sub.f are the velocities of the air exiting the nozzle and the flue gas, respectively, and where a is between 0.3 and 1.0 and where Y is between 0.3 and 0.8.

A water faucet or water tap includes, in its base area or other suitable area or region, a built-in or embedded or integrated filtering mechanism. The filtering mechanism includes a nonelectrical filtering chamber, having a cavity for securing therein a replaceable water-filtering capsule. A suitable water-filtering capsule, having an active filtering component or a passive filtering component, is inserted into the non-electrical filtering chamber, and can be removed from it for periodical replacement. Optionally, the water-filtering capsule includes a scent-producing agent, a flavor-producing agent, or a nutrient or a supplement, which are added to the filtered water. Optionally, a bypass mechanism or water-diverting mechanism enables to select between: a first mode in which a first water-outlet outputs non-filtered mixed hot-and-cold water; and a second mode in which a second water-outlet outputs filtered cold water or filtered room-temperature water.

The invention relates to a method for treating emergency spill or leak of halogen which is bromine or chlorine, comprising contacting an aqueous solution of quaternary ammonium halide with the halogen.

Embodiments disclosed herein include a plasma source, and an abatement system for abating compounds produced in semiconductor processes. In one embodiment, a plasma source is disclosed. The plasma source includes a body having an inlet and an outlet, and the inlet and the outlet are fluidly coupled within the body. The body further includes inside surfaces, and the inside surfaces are coated with yttrium oxide or diamond-like carbon. The plasma source further includes a flow splitter disposed in the body in a position that formed two flow paths between the inlet and the outlet, and a plasma generator disposed in a position operable to form a plasma within the body between the flow splitter and inside surfaces of the body.

An enhanced, surface modified activated carbon for filter media, having a higher capacity for removing specific contaminants, such as H.sub.2S, SO.sub.2, Cl.sub.2, CCl.sub.4, NH.sub.3, and HCHO, and a process for making the same. The surface of the activated carbon is modified with molybdenum and molybdenum-derivatives to enhance the activated carbon chemisorption capacity.

In methods of and/or plants for manufacturing cement clinker, the amount of chloride bypass exhaust gas 79 can be substantially decreased, when using previously cooled chloride bypass exhaust gas 81 and/or cooled kiln exhaust gas as coolant for the chloride bypass exhaust gas 39 prior to deducting the chloride bypass exhaust gas 39.

A chemical substance concentrator includes a tubular body, and a plurality of adsorption parts provided with predetermined intervals on a surface of the tubular body facing an inside of the tubular body. The chemical substance concentrator can cause a sample to easily pass through the chemical substance concentrator.

A healthy gas generating system for generating healthy gas for inhalation by a user includes an electrolysis device, a gas mixing device, and a backfire barrier. The electrolysis device electrolyzes water to generate a gas with hydrogen. The gas mixing device includes a mixer and a vibrator for mixing the combination gas with an atomized gas to produce the healthy gas. The backfire barrier is configured on the output of the gas mixing device or the gas passage of receiving the combination gas to avoid the backflow of the gas.
