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.
The Opsis monitoring solution for mining and smelting applications is based on either DOAS or laser diode technique. Opsis non-contact monitoring solutions are very well suited for applications in the Mining and Smelting Industries, as the flue gas conditions often involves high temperatures and high dust concentrations. The on-line, open-path systems are used for monitoring HF, sulphur dioxide, SO3 and HCl in potrooms, in fence-line applications and in continuous emissions monitoring.
The Opsis monitoring solution in aluminium smelters is based on either DOAS or laser diode technique. The on-line, open-path systems are used for monitoring HF and sulphur dioxide in potrooms, in fence-line applications and in continuous emissions monitoring. Opsis has long experience of monitoring in aluminium smelters.
The Opsis open path monitoring system is an excellent tool for monitoring 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.
Steel mills include a multitude of activities that generate gaseous emissions. Besides continuous emissions stack monitoring, the applications in a steel mill also include process mesaurements that provides important data to the operators in order to optimize the steel making process.
Various pollutants form in the cement manufacturing process, especially when alternative fuels and waste-derived fuels are used. Typically a cement kiln using these fuels is a required to monitor hydrogen chloride (HCl). Gasmet CEM II is EN 15267-3 approved for HCl measurement in 0 … 15 mg/Nm3 range.High process temperatures result in generation of more nitrogen oxides (NOx) than in typical municipal waste incineration.
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.
OPSIS non-contact monitoring solutions, based on either DOAS or TDL techniques, are very well suited for applications in the mining and smelting Industries, as the flue gas conditions often involve high temperatures and high dust concentrations.
GasFinderFC can be configured to monitor CO and CO2 simultaneously, and combined with the short open path probe, can be set up across roads to monitor instantaneous emissions of these gases from vehicles passing through the beam. Gross polluters can be identified and their number plates photographed.
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.
Opsis systems provide high-performance monitoring of the emission activities within an airport. The rapid system allows on-line monitoring of the emissions from each aircraft at take-offs and landings, monitoring of fugitive emissions from stationary sources and differing of the airport sources from the surrounding pollution sources.
The real-time monitoring of odorous gases or more classical pollutants emitted by industrial sites (wastewater treatment plants, refineries, landfills, etc.) appears nowadays as a requirement, in order to optimize the site process and operations, or communicate towards the neighborhoods and local public bodies.
While emissions can be measured directly at the source (in the stack, exhaust, etc.), ambient air measurement all around the sites provides a better accuracy and anticipate pollution episodes. This is why...
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.
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...
Traffic, especially in urban locations, is one of the greatest contributors to air pollution. Traffic produces a variety of different pollutants that include particulates, NO2, NO, CO, hydrocarbons and in some cases SO2.
The monitoring of roadside pollution can be challenging as often it is difficult to find suitable locations for large air quality monitoring systems and many sites that are available can be too far away to be representative of roadside air pollution.
Roadside pollution concentrations can change...
