Catalytic Oxidization. A principal technology for control of exhaust gas pollutants is the catalyzed conversion of these substances into innocuous chemical species, such as water and carbon dioxide. This is typically a thermally activated process commonly called catalytic oxidation, and is a proven method for reducing VOC concentrations to the levels mandated by the CAAA (see Catalysis). Catalytic oxidation is also used for treatment of industrial exhausts containing halogenated compounds.

This fan group, sometimes referred to as industrial exhaust fans , is characterized by its simple, rugged construction. 

Abatement of pollution in end-of-pipe solutions (automotive and industrial exhaust)... 

Applications of emission sensors can be found in remote sensing of hot, gasous samples, in particular (industrial) exhaust gases. 

Oxycat A catalytic oxidation process for removing combustible vapors from air and industrial exhaust gases. The catalyst is platinum on alumina, supported inside a porcelain tube. 

Catalysis plays a prominent role in our society. The majority of all chemicals and fuels produced in the chemical industry have been in contact with one or more catalysts. Catalysis has become indispensable in environmental pollution control selective catalytic routes are replacing stoichiometric processes that generate waste problems. The three-way catalyst effectively reduces pollution from car engines. Catalytic processes to clean industrial exhaust gases have been developed and installed. In short, catalysis is vitally important for our economy now, and it will be even more important in the future. 

Separating the carbon dioxide is expensive since the scrubbing process uses almost one-third of the energy produced by the power plant. It costs about 30 a ton to separate carbon dioxide from industrial exhaust, although the technology exists to cut this almost in half. One... 

PPG Biofilter provides biofiltration systems that degrade volatile organic compounds (VOCs) from contaminated industrial exhaust. Biofiltration is typically used to reduce hazardous air... 

It has to be noted that the adsorption of reactants is generally not uniform across the catalyst surface. Adsorption, and therefore catalysis, takes place mainly at certain favorable locations on a surface called active sites. In environmental chemistry, catalysts are essential for breaking down pollutants such as automobile and industrial exhausts. 

In addition to VOCs, specific industrial exhaust control technologies are available for nitrogen oxides, NO, carbon monoxide, CO, halogenated hydrocarbon, and sulfur and sulfur oxides, SO. ...

Three commercial processes, namely the oxidation of volatile organic compounds (VOC) for purification of industrial exhaust gases, SO2 oxidation for sulfuric acid production, and NO reduction by ammonia, have employed the periodic flow reversal concept. 

Methanol is particularly interesting because it can be produced by hydrogenation of the greenhouse gas C02 (see Section 5.3.5). Thus, anthropogenic C02 (e.g. from industrial exhaust or coal power plants) could be used for its manufacture. The amount of C02 emitted upon methanol combustion is then equal to the amount consumed during its production. Such C02 recycling via methanol has been proposed by Olah et al. [2] as a carbon-neutral methanol economy. ...
