Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.
To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate. The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.
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.
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.
To monitor benzene emissions can be a challenge, but OPSIS makes it easy. Benzene is an aromatic hydrocarbon liquid that evaporates quickly if exposed to ambient air. It is one of the most commonly used substances in the chemical industry and it is known to cause cancer. For this reason, refineries in the United States must start monitoring fugitive emissions of benzene from January 30, 2018. This is part of the 2015 U.S. EPA Petroleum Refinery rule. In case a yearly rolling average of benzene concentrations...
OPSIS provides real-time, flexible monitoring of particulate matter in the ambient air. Particulate matter monitoring with OPSIS, is a cost-effective solution, is ideally suited for use in modern monitoring stations. It can be remote controlled and includes automatic calibration, features that frees time. The SM200 meets the new regulation for automatic monitoring of PM10 and PM2.5. It also meets the new regulation for particulate matter sampling on filter membranes for further analysis of cadmium, nickel, PAH...
To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.
Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring. Cerex multi-gas analyzers offer significant advantages over single gas analyzer arrays, electro-chemical sensor arrays and time integrated air sampling hardware.
Measurement of SO2, sulfuric acid mist and greenhouse gas emissions from sulfuric acid plants requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.
Measurement of particulates, SO2, NOX, TRS and greenhouse gas emissions from the Pulp & Paper industry requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.
