organic pollutant Applications

  • Organic Micro-Pollutants Removal

    Organic Micro-pollutants are low and trace levels of synthetic organic substances released in water through human activity. They can be found in industrial, agricultural and domestic wastewater streams. Some of the most difficult-to-treat wastewater contains micro-pollutants such as persistent organic pollutants (POPs), herbicides and pesticides, personal care products (PCPs), toxic chemicals, carcinogenic and endocrine disruptive compounds (EDCs), and emerging contaminants.

    High quality gas sensor solutions for total organic carbon (TOC)

    Minimising costs through measurement of CO2 concentration. Both water suppliers and water users need to know the quality of the water they are supplying, using and disposing of so as to minimise their costs. One measure of water quality is the organic carbon content (TOC). TOC is measured by oxidising the organic carbon to produce CO2 which is then measured and the value converted into a TOC measurement. Edinburgh Sensors supply sensors to measure the CO2 concentration produced by oxidising the organic carbon in a water sample, allowing the TOC to be calculated. This TOC value determines one measure of how clean the water sample is.

    Petrochemical

    Durable regenerative thermal oxidizer (RTO) technology is at the core of our systems. MEGTEC designs and engineers system solutions to meet your special requirements, ranging from energy-efficient treatment of dilute volatile organic compound (VOC) flows, such as tank ventilation, to demanding applications utilizing VOC energy for secondary heat recovery; for example, in the form of process streams. This can include pre- and tail gas treatment systems, and could handle hazardous components such as sulphurous or chlorinated hydrocarbons. For special requirements, we can offer FTO (flameless thermal oxidation) and we can design systems operating safely on oxygen contents below 5%.

    VOC and HAP Abatement

    As is the case for many industrial manufacturing processes, emissions are best destroyed through the use of thermal and catalytic oxidation technologies. Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) are destroyed through the use of high temperature combustion with direct heat recovery. The harmful air pollutants are converted to heat, water vapor and carbon dioxide, creating a destruction efficiency greater than 99%.

    Air pollution control for the ethanol/biodesel industry

    Renewable energy plants are expanding and developing at a significant rate in North America and throughout the world. In the United States, the Clean Air Act for reformulated gasoline (RFG) mandates a 2wt.% oxygen requirement, driving the demand for more production. Ethanol is the most viable additive because it is a clean-burning fuel produced from renewable, domestic biomass sources. However, the production of these fuels can result in unacceptable levels of volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM) and hazardous air pollutants (HAPs), all regulated by environmental agencies.

    Industrial air pollution control for the chemical and petrochemical industry

    CTP systems can be found in every leading production company: thanks to the experience and the expertise developed in partnership with our customers for processes with inconsistent waste gas volumes; varying concentrations of organic components; gases contaminated with aerosols. CTP has installed systems for waste gas streams ranging from 1,000 to 200,000 Nm³/h. CTP supplies this industry with mainly catalytic systems, regenerative thermal oxidisers (RTO) and adsorbers. As the flue gases in this industry are often explosive mixtures, CTP systems have to be completed with special safety conduits and filters to help reduce hazards during continued operation.

  • Removal of organic compounds & toxity for wastewater treatment industry

    Federal and State regulatory agencies are increasingly requiring additional water quality testing and controls of the toxicity of discharges to receiving streams. Granular Activated Carbon (GAC) helps meet these pollution regulations. If organic chemicals have been identified as contributing to discharge toxicity, Calgon Carbon Corporation can work with facilities, and their engineering firms, to help meet stringent criteria associated with their NPDES permit. GAC can be employed as a cost-effective treatment for removal of organic compounds and toxicity. Even in situations where activated sludge treatment or powdered activated carbon is used for primary wastewater treatment, post treatment with GAC may be necessary to achieve toxicity compliance.

    Measuring aromatic hydrocarbons (BTEX) for pollution control and environmental monitoring

    The Series 8900 BTEX Analyzer provides direct measurement of Benzene, Toluene, Ethylbenzene, and Xylenes in ambient air. This instrument is utilized in ambient air networks around metropolitan areas and fence-line monitoring at industrial sites. The Series 8900 BTEX Analyzer employs a photoionization detector (PID) as the sensing element. This detector is specific to volatile organic compounds. The Benzene, Toluene, Ethylbenzene, and Xylene`s in the gas sample are physically separated using proprietary GC columns.

    Low concentrations monitoring of benzene and aromatic hydrocarbons (BTEX) for pollution control and environmental monitoring

    With over 15 years of experience in the measurement of volatile organic compounds (VOC), Environment SA announces the VOC72M, a new generation analyzer for the measurement of BTEX compounds by gas chromatography with photo-ionization detector (PID). The VOC72M can handle up to 40 compounds and eight configurations for analysis. This compact and fully automated analyzer with wide voltage range specifications (90-240V) provides equivalent performance to the laboratory chromatographs and is particularly suited to fixe or mobile ambient air quality monitoring laboratories. The VOC72M is fitted with a PID detector new generation, much more sensitive, more stable and whose lamp does not need to be cleaned; the analyzer integrates flow control fittings a 3 levels security system built on and uses only one gas (nitrogen).

    Odor control for composite

    A Single Solution To Manage Composite Odors: Many resins used in the composite industry emit styrene vapors which are considered hazardous in high concentrations and whose odor is an unpleasant nuisance. This gas is categorized as a volatile organic compound (VOC) and listed by the United States Environmental Protection Agency (US EPA) as a Hazardous Air Pollutant (HAP). Styrene is considered highly reactive in the atmosphere and may contribute to smog formation and the production of secondary air pollutants.

    Waste recovery for energy & utilities

    In order to stay competitive and to be seen as being environmentally responsible, energy and utility companies are always looking for alternative routes to generate power. One method of doing this is by leveraging waste to energy incineration plants linked to the processing municipal solid waste. During this incineration process, APC residues, which are a mixture of fly ash, organic pollutants (including dioxins and furans), are generated and are classified as hazardous waste and have a detrimental environmental impact. This fly ash is subject to Air Pollution Control as it is contaminated with extremely high concentrations of heavy metals and toxic compounds like dioxins, linked to cancer and other health problems. Tetronics offers valuable waste recovery plants that can eliminate the hazardous element within the fly ash while generating an inert building aggregate with the remaining material.

    Determination of TOC in stack

    PROBLEM: The industrial chimney's emissions of Volatile Organic Compounds (VOCs) are becoming issues of global importance and to have an accurate knowledge about how to test VOC turns into a strategic issue. VOC emissions are quantified and monitored according to standard EN 12619, using FID analyser which uses hydrogen and other reference gases in pressurized cylinder. Operators must then approach the sampling point, often placed several meters from the ground, climbing chimneys of industrial settlements with instruments and cylinders. Is it possible making this job easier and safer? SOLUTION: Using the Polaris FID analyser produced by Pollution Srl, Italy, it is possible to carry out the VOCs monitoring according to EN 12619 without lifting accessories and heavy weights typically involved with FID analyser. Polaris FID analyser complies with this standard regulation but what is really a breakthrough and cutting-edge, is the unmatched portability and the next generation technology
