In the 1970s, power plant emissions from southern and central Europe began impacting Scandinavian forests. As a result, regulations took effect in countries like Germany restricting the emission of sulfur dioxide, the primary component of acid rain.
As the concern for “paper pollution” increases, pulp and paper companies are seeking for superior ways of controlling their emissions. Chemical recovery furnaces, combustion units, as well as lime kilns are some sources of SO2 and CO2 discharge from paper mills.Gases from recovery boilers are typically treated for SO2 removal with ...
With the dwindling supply of low sulfur content fuel, power generators will soon face the dilemma of switching to a higher sulfur content fuel in order to generate electricity; while still being required to meet their strict environmental SO2 emissions restrictions. Historically, non-regenerable alkali scrubbing processes (such as caustic, ...
The PeGASyS system incorporates the latest technology in portable gas chromatography, gas sampling and computer hardware. Because it is portable, the system can be easily transported to the plant site and quickly set up in an area as small as a desktop. The PeGASyS system analyzes the SO2 and O2 converter gas streams, detects leaks in gas-to-gas ...
Sulfur oxides are generated in combustion, especially SO2. Part of these oxides arrives at SO3, in variable proportions depending on each fuel compositions and the intrinsic performance of firing system. In the burned gases, SO3 meets the necessary conditions to change into sulfuric acid: water molecules, necessary catalysts (V2O5 or Fe2O3) ...
NILU can offer indoor air quality (IAQ) monitoring and assessment of possible impacts on both human health and materials, including cultural artefacts and structures. The institute conducts indoor air pollution measurements and assessments based on extensive experience in the field and the expertise obtained from research projects. The ...
Industrial pollution has historically represented the largest environmental impact in Norway. NILU has performed measurements, calculations, evaluations and impact assessments for the industry since the institute was first established in 1969. Air emissions can contain several different types of pollution, depending on the industry and what is ...
Here is a better way to make the important and urgent power plant air pollution control decisions. An integrated system provides the four knowledge needs: Alerts, Answers, Analysis, Advancement. You receive weekly Alerts with the latest regulatory and technical information on mercury, SO2, NOx and particulate. Answers to your questions are quickly ...
The latest intelligence on the volatile U.S. market as well as comprehensive current analyses of Asian and European power plant SO2 removal plans are included in this new on line version of a report which had been periodically published for more than two decades. Now thousands of forecasts are reviewed and needed changes made quarterly. Markets ...
