    Emission control solutions for biomass and coal combustion sector

    For particulate matter (PM) emission control in high temperature exhaust streams, such as those from biomass or coal boilers and heaters, common dedusters such as cyclones and multicyclones are not able to comply with current emission limits. This is mainly due to their low efficiency, particularly for small particles (less than 10µm). In order to meet emission limits this usually requires an additional investment in a final stage deduster. Bag filters (BF) are very efficient dedusters. They can also be...

    Gas monitoring instruments and systems for DeNOx process control

    In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

    Gas monitoring instruments and systems for flavoring agents

    Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.

  • Industrial monitoring solutions for the flue gas desulphurisation areas

    Most large coal fired plants have a flue gas desulphurisation (FGD) plant to lower SO2 levels to below emission limit levels. The CODEL GCEM 40 series is used to monitor SO2 levels after the FGD to ensure they are below required levels and to ensure that the process is not too efficient and using too much sorbent. In addition, many plants monitor pre and post the FGD to ascertain the efficiency of the plant.

    Air pollution control solution for cement industry

    The fundamental ingredient in concrete is portland cement. The cement manufacturing process requires a great deal of energy to heat the mixture of raw materials in a cement kiln. The main source of toxic emissions from a portland cement plant is the kiln. The treatment of kiln exhaust is similar to most incinerators processes. Scrubbers are the best choices for control of acid gases, fine particulate, heavy metals as well as dioxin and furans. The MACT II regulations, yet to be finalized, for cement kilns are...

    Gas monitoring instruments and systems for nitric acid process

    Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...

    Product recovery solutions for chemicals industry

    Efficient recovery of active pharmaceutical ingredients (APIs), chemical substances or food powders after drying applications such as spray and fluid bed drying is frequently a problem. The same problem occurs in many milling and micronization applications. The preferred way to recover these sensitive products is with cyclone collectors due to their direct powder capture. Unlike bag filters or wet scrubbers, cyclones minimize filter or product contamination and product cross contamination and can easily handle a...

  • Measurement solution for HF emissions from brickworks

    Brick kilns, as well as other plants such as ceramics manufacturers and fertiliser producers, are a major producer of hydrogen fluoride (HF) emissions. HF is highly reactive gas and seriously damaging to human health, so has strict emissions limits imposed by legislation. In addition to the effects to humans, emissions have been found to damage crops and fruit trees, as well as the general environment. The brick industry strives to reduce the amount of HF emissions and numerous projects have been carried out into...

  • Opacity monitoring for continuous emissions

    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...

    Emission control solutions for oil & gas industry

    In Fluid Catalytic Cracking (FCC)processes, widely used in oil refineries, the separation and recovery of powder catalysts is a major concern. Particularly, the concentration of catalyst after the FCC regenerator is usually over 150 mg/Nm3. Since these levels of emissions didn`t represent any environmental harm in the past, they were not controlled by any separator or filter. Plant managers main concern was to clean a fraction of the gas to produce energy in a Turbo Expander, or similar, while concentrating the...
