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.

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.
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.
The history of air pollution regulation dates back as far as the 13th century when in 1273, Edward I (Longshanks) of England prohibited the burning of sea coal in London. The smoke produced by its combustion was considered detrimental to human health.
By the late 19th and early 20th centuries, regulations were being passed that sought to control air pollution predominantly for smoke and odour control. Traditionally, regulators were concerned with the visual impact of the discharge from a stack or chimney. Therefore...

Procal´s analysers are used extensively in reporting and control applications in modern Biomass plants. The flexible and reliable instruments form the heart of the systems, enabling CO, NO2, NO, SO2, H2O, CO2, O2, dust and velocity to be measured.
Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be...
• Development of documents substantiating the volumes of emissions of pollutants into the air from stationary sources for enterprises, organizations and private entrepreneurs;
• Inventory of air pollutants emissions from stationary sources;
• Preparing, maintenance support of documentation for receiving a Permit for Emissions of Pollutants into the Air from Stationary Sources (PEPASS) *, issued by the Departments of Environment and Natural Resources of the regional state administrations of Ukraine;
Triboelectric dust probes installed in the clean gas duct after bag filters, cartridge filters or centrifugal separators (cyclones) are used to detect faulty, damaged or leaking filters. This early detection of failures minimises product loss, improves environmental conditions and problematic dust emissions.
Benefits include low initial outlay, no consumables and low maintenance requirements.
There are more than 10,000 Dr. Foedisch filter monitor devices installed worldwide in the food processing, cement,...
Control of fugitive dust in the mining industry and in particular open cut operations is of great concern to the local community, environmental protection authorities and of course the mine operators. Dust emissions can cause both nuisance effects as well as health effects and so mines typically employ multiple dust suppression activities to minimise their environmental impact. Many of these activities can be expensive to operate and depending on environmental conditions, at the time, may not actually be effective...
