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 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.
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.
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.
Process control and emissions monitoring in a brick plant is a challenge due to the high concentrations of HF. The HF is generated in the process and gas phase HF can reach 50 mg/m3 or more. To use an extractive system in this environment will demand a lot of maintanence.
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.
Process control and emissions monitoring in a glass manufacturing plant is a challenge due to high temperature in the flue gas. The OPSIS DOAS system provides the glass industry with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method that uses an optical path to measure across the duct. A single OPSIS system will measure all relevant gas componensts such as NOX, SO2, CO, CO2, H2O, O2, and others.
Process control and emissions monitoring in a chemical plant is a challenge due to corrosive gases, high dust load, and high temperatures. To use an extractive system in this environment will demand a lot of maintenance.
Process control and emissions monitoring in a mineral wool plant is a challenge due to the presence of phenol and formaldehyde. To use an extractive system in this environment will demand a lot of maintenance. The OPSIS DOAS system is different and provides plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the duct.
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.
Process control and emissions monitoring in cement plants, can be a challenge due to the dusty and corrosive environment. OPSIS provides an accurate system that will operate with high performance and a minimum of maintenance.
The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.
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.
Local authorities incinerate domestic waste and other kinds of waste that typically include plastics, batteries and a diversity of unknown compounds. These may all produce acidic and other toxic emissions. Therefore, efficient flue-gas cleaning systems are needed to prevent their release into the environment.
The Sorbisense method allows for efficient monitoring of the sewage system and can help reduce costs of operation and environmental impact.
The method is particularly well suited for tracking the source of periodic discharges, the identification of faulty pipe connections of the measuring of values in the recipient.
The method also allows for measurements in dynamic sources - such as emissions from roads, roofs, parking lots and overflow
The Sorbisense method allows for measuring the average concentration of substances in groundwater over a period of up to 1 month with only one sample.
The system provides methods for measurements in both unsaturated and saturated zone and provides access to dynamic boundaries of contaminants and more realistic risk assessments. For example, through direct measurements of seepage from contaminants and by continuous measurement of emissions from cropland.
The Procal 2000 emissions analyser is ideally suited to the harsh environments associated with Paper & Pulp Plants. The in situ, multi-component Continuous Emission Monitoring (CEM) system has an integrated auto-zero and calibration facility, thereby removing the need for intervention by maintenance staff under normal conditions.
Monitoring of emissions from incinerators is a demanding application for Continuous Emission Monitoring Systems. The emissions produced are highly corrosive, some of the gases are soluble and, because the waste being burnt is constantly changing, the resulting stack gas temperature varies widely.
