    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%.

    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%.

    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.

    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.

    Analysis of VOC compounds in water by Purge & Trap or dynamic headspace

    Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA – “Volatile organic compounds in water by purge and trap capillary column gas chromatography with photoionization and electrolytic conductivity detectors in series – Revision 2.1”. - 524.2 method from US EPA – “Measurement of purgeable organic compounds in water by capillary column gas chromatography/mass spectrometry – Revision 4.0”.

    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

    Low level measurement of VOCs and Terpenes close to the sea and the Landes Forest

    It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle phase. The current number is that, on a global scale, SOA would represent around 60% of the overall OA.3 However, recent global mass-balance estimations for the removal of volatile organic compounds (VOC) suggest that this number could under-predicts SOA production.4 Recent field measurements in urban locations are also in support of a larger share, indicating that SOA is the dominant fraction of OA, with amounts considerably 20 greater than models predictions.

  • Measurement solution for measuring total VOC via FTIR

    Current Total VOC Measurements

    The most common, and current standard, method for measuring Total Volatile Organic Compounds (VOC) is the use of a Flamed Ionisation Detector (FID). This gives a representative value of the total carbon content of a gas stream, as the FID cannot tell which specific organic compounds are present.
