A plasma abatement process for abating effluent containing compounds from a processing chamber is described. A plasma abatement process takes gaseous foreline effluent from a processing chamber, such as a deposition chamber, and reacts the effluent within a plasma chamber placed in the foreline path. The plasma dissociates the compounds within the effluent, converting the effluent into more benign compounds. Abating reagents may assist in the abating of the compounds. The abatement process may be a volatizing or a condensing abatement process. Representative volatilizing abating reagents include, for example, CH.sub.4, H.sub.2O, H.sub.2, NF.sub.3, SF.sub.6, F.sub.2, HCl, HF, Cl.sub.2, and HBr. Representative condensing abating reagents include, for example, H.sub.2, H.sub.2O, O.sub.2, N.sub.2, O.sub.3, CO, CO.sub.2, NH.sub.3, N.sub.2O, CH.sub.4, and combinations thereof.

Provided are an exhaust gas treatment system and method for regenerating the exhaust gas treatment system. The exhaust gas treatment system comprises: an oxidation catalyst assembly; a particulate filter downstream of the oxidation catalyst assembly; a reducing agent dosing device downstream of the particulate filter; and a selective catalytic reduction device downstream of the reducing agent dosing device. The oxidation catalyst assembly comprises a first oxidation catalyst to selectively oxidize hydrocarbons in the exhaust stream, at least partially, with substantially no concomitant oxidation of sulfur oxides in the exhaust stream; and a second oxidation catalyst downstream of the first oxidation catalyst, to oxidize hydrocarbons or partially oxidized hydrocarbons having slipped through the first oxidation catalyst, as well as to concomitantly oxidize NO to NO.sub.2. The system can be regenerated when running on high-sulfur fuels to regenerate the particulate filter as well as remove sulfur species deposited on the system catalysts.

A method for the treatment of flue dusts containing arsenic and/or antimony from pyrometallurgical methods, wherein a reducing agent is added to the flue dusts, the flue dusts are heated together with the reducing agent, and volatile components are separated from a slag. The reducing agent is a carbonaceous compound.

An integrated amine and redox gas treatment system is configured to treat an influent hydrocarbon containing stream. The system includes a reduction oxidation unit connected directly downstream of an amine unit. The amine unit is configured to separate the influent fluid stream into a first amine effluent stream including hydrocarbons and a second amine effluent stream including a connection pressure and comprising CO.sub.2. The reduction oxidation unit is configured to receive the second amine effluent stream from the amine unit and operate at the connection pressure while releasing a reduction oxidation effluent stream including purified CO.sub.2. The connection pressure includes a single pressure or a plurality of pressures at which both the amine unit and the reduction oxidation unit are configured to operate.

Disclosed is an energy hydrogen water dissolving device that passes a clean water source through a pressurized pump. A part of the water is sent to a hydrogen production equipment and decomposed into hydrogen and oxygen, and the other part of the water is driven to an energy hydrogen water dissolving and storage tank. The oxygen formed by the hydrogen production equipment is discharged to the outside or returned to the clean water source, and the hydrogen formed by the hydrogen production equipment is connected and sent to an input end of the pressurized pump, pressurized and mixed uniformly by the pressurized pump and outputted to the clean water, so that the water liquid entering into the energy hydrogen water dissolving and storage tank becomes high dissolution hydrogen water. The energy hydrogen water dissolving and storage tank contains an energy mineral, a hydrogen molecule mineral and a terminal filter, and the water liquid discharged from the energy hydrogen water dissolving and storage tank is formed into healthy drinking water with tiny water molecules, weak alkaline, high negative potential and high dissolution hydrogen molecules

This boiler has a flue in which a reducing agent supplying device and a selective reduction catalyst are provided, a bypass flow path bypassing economizers is provided, and a first closing device partially closing the bypass flow path and a second closing device partially closing the flue are also provided. A plurality of first closing members, serving as the first closing device, are provided along the direction in which exhaust gas flows through the flue at a predetermined spacing in the width direction of the flue. A plurality of second closing members, serving as the second closing device are provided along the vertical direction at a predetermined spacing in the width direction of the flue. The first closing members and the second closing members are arranged so as to be displaced from each other in the width direction of the flue.

A method for conversion of carbon dioxide to carbon monoxide comprises: introducing a flow of a dehumidified gaseous source of carbon dioxide into a reaction vessel; and irradiating dried, solid carbonaceous material in the reaction vessel with microwave energy. Heating of the irradiated carbonaceous material drives an endothermic reaction of carbon dioxide and carbon that produces carbon monoxide. At least a portion of heat required to maintain a temperature within the reaction vessel is supplied by the microwave energy. Carbon monoxide thus produced is allowed to flow out of the reaction vessel.

Each of the plurality of aluminum plates includes a solid filtering agent, such as activated charcoal and, optionally, sodium tetra borate. The container can further include an inlet for receiving polluted air, an outlet for discharging purified air, and a pathway extending between the plurality of aluminum plates from the inlet to the outlet. The nanoparticle purifying system includes a removable lid for disposing on the container. Each of the plurality of aluminum plates can include an adhesive, such as hot glue and/or carpet glue, for attaching the solid filtering agent to the surfaces of the plurality of aluminum plates and interior surfaces of the container.

A multi-function duct for a dry scrubber system useful for processing a gas stream, such as a flue gas stream produced by a fossil fuel fired boiler, a combustion process or the like, is provided. The multi-function duct is useful for a circulating dry scrubber (CDS) dry flue gas desulfurization (DFGD) system operable for dry or moistened reducing agent distribution into a flue gas stream flowing therethrough. As such, the distributed dry or moistened reducing agent reacts with acid gas in the flue gas to produce a dry reaction product.
