摘要： A method for removing methane and non-methane volatile organic compound concentrations from a gas stream. The method includes exposing the target gas to a halogen gas and a light from a suitable light source having a wavelength sufficient to activate halogen gas to halogen radicals, wherein the halogen radicals react with the VOC in the target gas to provide the target gas with a removed concentration of VOC as well as a device including a reaction chamber for reacting the halogen radicals with the VOC in the target gas.

摘要： The disclosure provides seven integrated methods for the chemical sequestration of carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2) (collectively NO2, where x=1, 2) and sulfur dioxide (SO2) using closed loop technology. The methods recycle process reagents and mass balance consumable reagents that can be made using electrochemical separation of sodium chloride (NaCl) or potassium chloride (KCl). The technology applies to marine and terrestrial exhaust gas sources for CO2, NOx and SO2. The integrated technology combines compatible and green processes that capture and/or convert CO2, NOx and SO2 into compounds that enhance the environment, many with commercial value.

摘要： One aspect of the invention relates to a method comprising a single-stage conversion of an atmospheric pollutant, such as NO, NO2 and/or SOx in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO20), wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

摘要： The disclosure provides devices, methods, and systems for treating reactive metals and other reactive species produced during operation of thermal solid-state gas generators. Thermal energy, which may be derived from the gas generation process, physical contact with the evolved gases, or a dedicated or shared heat source, is used to release a gaseous species that neutralizes the reactive species. In some embodiments, the neutralization reaction causes the release of additional product gas(es).

摘要： A method of detoxifying an exhaust pipe in a film forming apparatus configured to supply a raw material gas contending a harmful component and a reaction gas capable of generating a harmless reaction product by reaction with the raw material gas into a process chamber to perform a film forming process on a substrate while independently exhausting the raw material gas and the reaction gas from a raw material exhaust pipe and a reaction gas exhaust pipe connected to the process chamber, respectively, is provided. The method includes supplying the reaction gas into the raw material exhaust pipe to detoxify an interior of the raw material exhaust pipe during a predetermined period in which the film forming apparatus is operated and the film forming process is not performed.

摘要： Methods related generally to the removal of atmospheric pollutants from the gas phase, are provided. The methods involve contacting a first stream comprising NO and/or NO2 with a second stream comprising (ClO2)0 to provide a third stream comprising NO and NO2 at a molar ratio of about 1:1; and contacting the third stream with a fourth stream comprising an aqueous metal hydroxide (MOH) solution to convert NO and NO2 to MNO2.

摘要： Processes for manufacturing a purified aromatic carboxylic acid include oxidizing a substituted aromatic compound in a reaction zone to form a crude aromatic carboxylic acid and a gaseous stream; heating the crude aromatic carboxylic acid in a pre-heating zone, contacting the crude aromatic carboxylic acid with hydrogen in the presence of a catalyst in a hydrogenation reactor to form a purified aromatic carboxylic acid, crystallizing the purified aromatic carboxylic acid in a crystallization zone to form a slurry stream comprising solid purified aromatic carboxylic acid and a vapor stream. At least a portion of the vapor stream is directed to the pre-heating zone and at least a portion of the vapor stream from the pre-heating zone is vented to the off-gas treatment zone in order to achieve energy savings.
