摘要:
Disclosed herein is a system for purifying air; for the capture of solid residues (soot), and the transformation of COx and NOx (and even methane) present in contaminated air generated by industrial combustion.The purifying air system comprises an air entrance (c); a first module (A), made up of mechanical filters; a second module (B), downwards from the first module (A), and it corresponds to a series of small reactors with molecular converters (nucleophile chemical agents) to capture and transform carbon oxides (COx) and nitrogen oxides (NOx); and an exit for decontaminated air (D).
摘要:
There are provided methods for treating a fluid having an undesirable odor. The methods comprise contacting the fluid with a H2O2 basic aqueous oxidizing composition and/or with a H2O2 acidic aqueous oxidizing composition. Optionally, the fluid can be further treated by contacting it with activated carbon and/or by submitting the fluid and the composition to UV radiation when they are contacting together.

摘要:
The invention relates to a coating composition comprising: (a) 10% to 99.9% by weight of resin based on the total weight of the coating composition; and (b) 0.1% to 20% by weight of a formaldehyde scavenger based on the total weight of the coating composition, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature. The invention relates to use of a coating composition for removing free formaldehyde from the environment, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature.
摘要:
A method for leaching of minerals and sequestration of CO2 is disclosed, wherein the method comprises forming a rock pile; injecting exhaust gas containing CO2 in the lower part of the rock pile; spraying leaching liquid on top of the rock pile; collecting enriched leaching liquid from a lower part of the rock pile; precipitating mineral carbonates from the enriched leaching liquid, or further extracting dissolved elements or compounds.
摘要:
Methods for controlling mercury emissions and/or reducing corrosion of equipment used in combustion processes are provided, and more particularly, methods for controlling mercury re-emissions from a wet flue gas desulfurizer and/or reducing corrosion of the wet flue gas desulfurizer.
摘要:
A wet flue gas desulfurization process uses byproduct polyester streams such as those from the production of PLA and/or PGA consisting of hydroxy acids and other organic acids to catalyse the solubilization of calcium from limestone and to further catalyse the reaction of calcium with SO2 for desulfurization and thereby provide significant improvement in process efficiency.
摘要:
A system and method of reducing ammonia emissions. The system and method include a facility having a waste storage compartment below a floor comprised of slats with openings therebetween. A plurality of injection pipes are attached to a bottom surface of the slats. Each of the plurality of injection pipes includes a plurality of precipitation nozzles.
摘要:

In several embodiments, systems including activated carbon filters, adsorbents, odor adsorbing fabrics, masks, clean air members and clean air supply assemblies are provided in order to perform said methods. In some embodiments the systems and methods facilitating the treatment of traumatic brain injury, ischemic stroke, atherosclerosis, spinal cord trauma, and neurodegenerative illnesses with compositions comprising DMSO.
摘要:
A filter for use in an ultraviolet photocatalytic oxidation air purification system having a filter surface treatment that enhances removal of volatile silicon-containing compounds (VSCCs). The surface treatment may create an acidic site on the filter, increase the surface area of the filter, or facilitate preferential interaction between the surface and the VSCCs, thereby promoting the VSCCs to bond with the VSCC filter. Removal of the VSCCs prior to the VSCCs reaching the photocatalyst increases the useful life of the photocatalyst.
摘要:
A process for maintaining a low carbon monoxide content in a carbon dioxide product that is made in a synthesis gas purification process is disclosed. More particularly, the invention involves an improved process in which a portion of a loaded solvent is sent through a carbon dioxide absorber instead of to a series of carbon dioxide flash drums.
