Rich-burn engine exhaust, when uncontrolled, can have wide concentration ranges and both CO and NOX can fluctuate significantly. The on-board CO dilution system will automatically set-up for optimum testing, perfect for a rich burn engine. Lean-burn engines have different exhaust characteristics, but NO2 can make up a significant portion of the total NOX measurement. The 350 measures both NO and NO2 for proper lean-burn engine set-up.
Due to high concentration, replaceable interference filters keep the sensors...
Monitoring stack emissions is a fundamental requirement for most industrial processes. Our gas analysers, dust monitors and flow monitors are designed for a wide range of applications and can operate as a fully integrated system or as stand alone instruments.
From the environmental point of view, an issue is any solid, liquid or gaseous substance introduced into the atmosphere that can cause air pollution. Given the wide variety of substances present in the atmosphere, have been proposed several methods of classification: Primary pollutants can be of gaseous or particulate.
The Environics Series Continuous Emissions Monitoring Calibration Systems (CEMCS) have been used in CEM vans and laboratories for over twenty years. They meet or exceed the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M.
Our systems are custom built, computerized, mass flow controller based gas calibration systems which allow you to dilute a single high concentration cylinder of span gas to low levels for the calibration of gas analyzers.
Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.
Modern nozzle and turbine technology developed by EmiControls is also used as a basis for the evaporation of water. This might typically be needed in open-pit mining, for example, to deal with large unwanted pools of water. Special nozzles can be used to atomize the water for evaporation. Evaporation is also useful in salt production. The tried and tested EmiControls technology can make the rate of evaporation much faster than the natural speed of evaporation, which helps the operators save an enormous amount of...
Protea has used our VOC gas analysers in many projects requiring the monitoring of complex mixes of VOCs. In the chemical and pharmaceutical industry, VOC abatement plants such as scrubbers and carbon-bed systems are typical installations where the use of Protea analysers and our VOC analysis expertise have proved valuable to plant operators. They prove a very powerful and flexible tool in both process gas measurements and VOC emissions monitoring. In the laboratory, Protea can deliver instruments with all the...
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives...
Continuous Emissions Monitoring Systems (CEMS) are used to measure flue gases from stationary sources at a wide variety of regulated industrial facilities, including power plants, petroleum refineries, petrochemical plants, waste incinerators, pulp and paper producers, and many others. The types of air pollution measured from these sources vary widely based on the industry and process, and many are regulated by government agencies around the world.
Motor vehicle emissions are a major source of air pollution in urban areas and impact the lives of billions of people every day around the world. Motor vehicle exhaust contains toxic chemicals that are harmful to people’s health when exposed at certain levels. These toxic fumes cause smog in the atmosphere, which can affect very broad regional air sheds and contribute to the formation of cancer. Teledyne API has several products specifically designed to meet the challenging demands of near-roadside air...
Commonly, activated carbon beds are used as abatement systems on plant, with emissions being reduced by adsorption onto the bed. The efficiency of any abatement system is critical to its operation, not just in ensuring emissions are reduced as much as possible, but an efficient bed has cost savings for the operator.
A large pharmaceutical plant runs a Thermal Oxidiser on plant to incinerate their solvent-containing gas streams before emission. When the oxidiser is offline, then the plant must monitor the release of solvent to the atmosphere. A ProtIR 204C fixed monitoring system was installed that continually measures 24 plant solvents, including Acetone, Cyclohexane, DCM, DMF, IPA, MIBK, Toluene and THF. Given the high levels that are possible, the system has an active dilution system, reducing the concentration of the...
Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.
The ultra-fast analysis capabilities of IONICON PTR-TOF instruments are essential for eddy covariance flux measurements, allowing to study deposition and emission rates of biogenic volatile organic compounds (BVOCs).
OPSIS offers fully automated system solutions for continuous monitoring in power plants. The monitoring systems have been tested and approved by the German TÜV and the U.S. EPA among others, for the best performance and longest calibration interval.
Make more out of your mill. OPSIS tested and approved monitoring systems provide cost-effective and reliable on-line monitoring of several gas compounds, such as both high and low concentrations of methane, moisture, carbon dioxide and hydrogen sulphide, at several locations.
A new EC regulation states that diesel engines need to have active cleaning with urea injection in order to reduce NOx emissions. In order to control the urea dosage, a reliable measurement system is required. OPSIS LD500 laser diode gas analyser for monitoring ammonia (NH3), has been tested and approved by German TÜV, in accordance with the EURO VI standard.
The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these organisms at the entrance and exit of the canal, generating alarms in the presence of toxic substances.
The OPSIS open-path monitoring system is an excellent tool for monitoring the air quality, fugitive emissions and gas leaks at industrial sites. By arranging monitoring paths strategically at locations outside the borderline of an industrial area, fugitive emissions and gas leaks will effectively be detected. By combining the measured gas data with meteorological parameters information such as where the pollution sources are located and the strength of the emissions can be calculated, using the EnviMan software.
