The metal industry comprises a large variety of different branches, beginning with metal winning and recovery, metallurgy, metalworking and extending to manufacture of machines and devices for which metal finishing and electroplating are indispensable process steps for quality standards. These industries face the difficulties of improved process control and lower environmental stress. AppliTek implements on-line monitoring in specific processes of the metal industry to increase process efficiency and lower...
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.
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...
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.
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.
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.
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.
The nature of steel manufacturing processes places severe limitations on the monitoring methods that can be used. Aggressive environments combined with high levels of particulates and gases make the choice very limited.
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 gas monitoring system is designed for monitoring in stacks and gas ducts in chemical industries, both in order to increase plant efficiency and to monitor emissions. The Opsis systems have been internationally approved by e.g. the German TÜV and the U.S. EPA.
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 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 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.
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.
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.
