When extracting and refining valuable geological materials from the earth (eg. limestone, aluminum oxide, gold), a variety of industrial combustion processes are required. The machinery used in these processes such as industrial engines, boilers, and smelters can emit highly toxic gases that are harmful to the environment and to human life. Using a portable emissions analyzer enables mining personnel to ensure personal and environmental safety, while optimizing the performance of the mining operation.
There are many locations that should be measured and monitored with a portable emissions analyzer to maximize product quality, combustion efficiency, safety, and emissions reduction in a cement plant including the following:
Marine vessels can emit air pollution such as CO, CO2, NOx (NO+NO2), and SO2 from their diesel engines and onboard incinerators. MARPOL Annex VI and the technical code for control of emissions of nitrogen oxides (NOx Technical Code) issued by IMO are internationally recognized regulations for the prevention of air pollution and emissions from marine vessels. Ships over 400 gross tons are also required to have an International Air Pollution Prevention (IAPP) certificate which can be obtained by confirming compliance...
Cogeneration, or combined heat & power (CHP), is the utilization of boilers, turbines, and/or engines to simultaneously generate electricity power and heat that can be useful in several ways such as for hot water, steam, district heating, and water desalination.
Fixed CEMS (Continuous Emissions Monitors) Measure at One Location
CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces.
If the CEM is measuring emissions that are higher than the regulated or permitted limits, it can be difficult to determine the source of the high emissions which could be from...
Testing the Performance of a DeNOx System Using a Portable Emissions Analyzer
Using Portable Emissions Analyzers to Measure the Performance of a NOx Reduction System in a Power Plant Boiler
The majority of power plants utilize NOx reduction systems (eg. Ammonia Injection, SCR, etc.) in their power boilers to ensure that the NOx emissions levels comply with current regulations. The frequent evaluation of the De-NOx system is fundamental to indentifying the adjustments necessary for an optimal and most cost efficient...
Many forklift trucks have internal combustion engines that burn propane, natural gas, diesel, or other fossil fuels. A portable combustion gas and emissions analyzer can be used to optimize combustion efficiency & maximize fuel savings, identify and quantify sources that can adversely affect safety and comfort in the work environment, and measure and reduce harmful emissions in the forklift engine exhuast gas.
There are many types of stationary and mobile internal combustion engines that can run off gas or diesel fuels. Engines can be lean burning at a high air to fuel ratio (AFR) or rich burning at a low AFR. The exhaust stack gases from engines contain pollutant gases including CO, NO, NO2, NOx, and CxHy hydrocarbons as well as particulate matter. Measuring the engine exhaust emissions is important for engine tuning, performance optimization, safety, and proving emissions compliance to regulatory authorities.
Accurate emissions monitoring from industrial processes is critical for determining overall system combustion effciency, environmental compliance and safety. However, there is no “one-size-fits-all” approach to proper emissions monitoring as each application encompasses different system considerations. The art of emissions monitoring and sampling requires:
New regulation forces ships to lower the emissions of SO2. Ships travelling in SECA areas has to either run on low sulphur fuel, or install SO2 scrubbers. To measure the SO2 emissions from a ship is not an easy task. OPSIS provides the Port Authorities with a unique measurement principle where the emissions from the ship is measured remotely. Light is passing the emissions and by analyzing the light, concentrations of SO2 can be measured.
During car manufacturing, Volatile Organic Compounds (VOCs) associated with the paints are emitted to the atmosphere. These are carcinogen, toxic and lead to tropospheric ozone formation. Therefore, VOC emissions must be reduced. With this aim, Chromatotec® airmoVOC C6-C12 (GC-FID analyzer) has been used to monitor VOC emissions from a car painting line. Indeed, it can measure concentrations ranging from very low (ppt) to high (ppm) level, so it is suitable for emission measurements. When coupled to MS...
The Road to Environmental Efficiency: Monitoring Nitrogen Oxides (NOX) and Hydrocarbons (CXHY) for Combustion Efficiency and Environmental Compliance.
Why Monitor Nitrogen Oxides (NOx)?
Nitrogen oxides (NOX) are toxic gases common to combustion processes that are highly regulated by state and federal Environmental Protection Agencies (EPA). Exceeding the environmental limit not only compromises worker health and safety, but may require supervisors to shut down a plant and/or pay a fine for noncompliance....
Coupling the BTrap analyzer to a thermogravimetric analyzer, an emission/adsorption chamber or simply to an oven, enables a much more comprehensive characterization of materials (e.g. ageing, toxicity linked to its lifecycle, repurposing) than with the systems classically used.
In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.
