Tri-Mer catalytic ceramic filters use glass emissions filter technology with nano-bits of SCR catalyst embedded in the walls - Case study
Filters are placed in housings and operate similarly to a “reverse pulse jet ceramic baghouse.” The filters are 10' long and 6" wide, with a wall thickness of approximately ¾ inch. Learn more information about Tri-Mer&rsquos;s hot gas filtration. The micronized catalyst offers a larger surface area for reaction than conventional SCR, with virtually no diffusion ...

Economic evaluation for air pollution control technologies selection in power plants processes
Air quality legislation is entering a transformation phase, shifting the concept of atmospheric emission control towards pollution prevention and emission minimization through a more integrated approach. This transformation, along with public pressure and increased foreign trade, is providing industries with incentives to consider their effect on the environment and to take action where required. ...

Effects of a zeolite SCR system on comprehensive emissions from a heavy-duty diesel engine
The effects of a zeolite urea-selective catalytic reduction (SCR) aftertreatment system on a comprehensive spectrum of chemical species from diesel engine emissions were investigated in this study. Representative samples were collected with a newly developed source dilution sampling system after an aging process designed to simulate atmospheric dilution and cooling conditions. Samples were ...

Anguil Catalytic Recuperative Oxidizer (CATOX) destroys Hazardous Air Pollutants (HAPs) and Volatile Organic Compounds (VOCs)
The Anguil Catalytic Recuperative Oxidizer destroys Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and odorous emissions at significantly lower temperatures than thermal oxidation technologies through the use of catalyst. HOW DOES THE CATOX WORK? VOC and HAP laden process gas is either pushed or pulled into a metal heat exchanger inside the oxidizer via a system fan. The ...

6 Tips for Reducing NOx Emissions
Many industrial processes utilize the combustion of natural gas, oil, or coal. However, the combustion of these fossil fuels produces nitrogen oxide or NOx, which contributes to smog and air pollution. Finding an effective and efficient solution for emissions can be frustrating and time consuming. In addition, federal regulations and energy standards can change, impacting your operational ...

Experience curves for power plant emission control technologies
This paper examines past experience in controlling emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) from coal-fired electric power plants. In particular, we focus on US and worldwide experience with two major environmental control technologies: flue gas desulphurisation (FGD) systems for SO2 control and selective catalytic reduction (SCR) systems for NOx control. We quantitatively ...

What are the useful exhaust gas treatment equipment in the factory?
Several types of equipment are used to treat factory exhaust, depending on the specific pollutants that need to be removed. 5 common types of fee processing equipment 1. Wet scrubber: wet scrubber is a type of air pollution control device that uses a liquid (usually water) to remove pollutants from a gas stream. The gas stream is forced through a mist or spray of the liquid, which captures the ...

The Requirement for SCR & SNCR
For decades coal has been the fuel of choice for most power stations around the world but also happens to be the most pollutant. The environmental regulation in Europe, China and India has stringent emission limits which coal fired power stations are finding it increasingly difficult and expensive to comply with and are therefore employing such systems as SCR and SNCR. Selective catalytic ...

A Modelling Approach to the Design Optimization of Catalytic Converters of IC Engines
ABSTRACT In this paper, a modelling approach to the design optimization of catalytic converters is presented. The first step of the optimization is the model-assisted sizing of catalysts. For a given inlet exhaust condition, a semi-empirical, experimentally calibrated, 0-D steady state catalyst model is employed to sort through a data base of catalysts under given restraints, yielding few ...

Factory Flue Gas Treatment Methods
Flue gas treatment is a process that removes pollutants from exhaust gases produced by industrial processes, power plants, and other sources before they are emitted into the atmosphere. Specific flue gas treatment processes can vary based on the type of contaminants and regulatory requirements. The following is an overview of typical flue gas treatment processes: Flue Gas Collection: The first ...
