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.
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 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.
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.
Requirements for monitoring emissions to air are governed by EU/UK legislation and are implemented in the form of a permit by the Environment Agency or local authority. The Dr Foedisch muti-component gas analysers continuously extract a gas sample from the exhaust stream via a stack probe into the analyser cabinet.
Both hot and cold gas systems are available, please contact us to discuss which system best suits your requirements.
The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a...
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.
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.
Measurement of greenhouse gases released from soil and water surface forms an important part of climate change study. Microbial activity in the soil or for instance the melting of permafrost releases greenhouse gases such as Methane and nitrous oxide N2O into the atmosphere. Measurement of the concentration for these gases inside an open-bottom soil chamber placed on the soil over time tells the emission rate (flux) per chamber footprint area.
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...
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...
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.
Opsis provides state-of-the-art monitoring equipment, fully meeting the high standards of monitoring performance and reliability that the cement industry requires. The Opsis in situ systems are designed to withstand environments with high particulate levels and high temperatures.
