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.
There are many cars that have a large impact on the environment in many places around the world. The emissions from fossil fuel cars are too high, and previous test methods have not given the full picture. Tests in a laboratory has, so far, been made indoors, in laboratories, and they do not match the reality, as they do not take into account the real driving conditions. Therefore, we have developed an accurate and reliable monitoring system that can measure the emissions in real life conditions. Based on our...
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.
To monitor H2S can be difficult. The UV absorption is without structure and the IR absorption has strong interference from H2O. The traditional way has been to remove all SO2 from the sample while keeping H2S, then convert H2S to SO2 ,and finally measure SO2 which then effectively yields the H2S concentration. The instruments used have often been ambient air SO2 analysers and extractive dilution systems. However, it is not unusual to experience practical problems with these type of installations.
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 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.
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.
Our Continuous Emission Monitoring (CEMS) DAS solution supports multiple emission regulation requirements and can work virtually anywhere in the world. We currently have a number of installations in North America and Middle East. Starting from Feb. 2014, after successful completion of the MCERTS certification process, the solution is offered in United Kingdom and other European countries. We are also interested in selling our products in Asia, South America and Australia regions.
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.
Process control and emission monitoring in a waste to energy plant is a challenge. A large number of gaseous components need to be measured with high accuracy. Almost 100% uptime is required and the monitoring system needs to be easy to maintain and fast to calibrate. The OPSIS system is tested and approved to have the best performance and longest calibration intervals, and provides the waste to energy plant with an accurate analyser that will operate with 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.
