Mechanochemical conversion of brominated POPs into useful oxybromides: a greener approach
Several brominated flame retardants (BFRs) have been found to have adverse effect on human health and the environment and classified as persistent organic pollutants (POPs). Mechanochemical destruction is a promising technology for the safe disposal of POPs because it can achieve their complete carbonization by solvent-free high energy ball milling at room temperature, thus preventing ...

Catalytic filter technology provides important flexibilityfor controlling PM, NOx, SOx, O-HAPS - Case study
Catalyst-embedded ceramic filters offer a way to remove NOx at lower temperatures, while simultaneously removing PM, SOx, and HCI. The technology also removes organic hazardous air pollutants, THC, dioxins, and mercury. Applications include the Cement NESHAP; Boiler MACT; incinerator CISWI MACT; Hazardous Waste MACT; glass furnaces; ceramics manufacturing, including tracking proppants, kilns, ...

In-Pile thermal desorption for treatment of Dioxin-Contaminated soil in Japan
Abstract A demonstration of thermal treatment of dioxin-contaminated soil was completed in Japan, under the sponsorship of the Japan Ministry of the Environment. TerraTherm’s proprietary In-Pile Thermal Desorption process was demonstrated to successfully treat the soil to the required standard of 1,000 picograms of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) toxic equivalents (TEQ) per gram ...

Flux force condensation scrubbing
Flux force condensation scrubbing technology is used to capture fine (submicron) particulate at extremely high efficiency. It is a preferred method when using wet scrubbing to collect and control dioxins from combustion sources. As an added benefit, through the use of condensation, the water vapor plume commonly associated with a wet scrubbing system can be effectively eliminated. The overall ...

A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source
The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...

Evaluation of Ecological Risks Associated with the use of Chlorine Dioxide for the Bleaching of Pulp: Scientific Progress Since 1993
1.1 Scope and Objectives A small number of viable options are presently available for the bleaching of wood pulp (delignification and brightening) during the manufacture of pulp and paper. The use of chlorine dioxide (ClO2) in the bleaching process has largely superceded the earlier use of Cl2, or elemental chlorine, in the majority of North American pulp mills: It was discovered over a decade ...

Carbon Injection Proves Effective In Removing Dioxins
Untitled Document Summary: During the past several years, there has been growing concern about emission of polychlorinated di-benzo-p-dioxins and polychlorinated di-benzofurans (PCDDs/PCDFs). Dioxins and related compounds are byproducts of combustion formed by recombining other organic constituents and chemical reactions in the combustion effluent-gas stream. ...
