    Emission control solutions for fuel oil combustion sector

    For PM emission control in high temperature exhaust streams, such as those from fuel oil boilers, common dedusters like Bag filters, have very high maintenance costs. The diesel and fuel oil fly ash can be quite sticky and clog to filter elements, which can be minimized with costly protection reagents or frequent filter elements changes. Flue gas cooling is needed in front of the filter when temperatures are higher than 200 ºC.

    Emission control solutions for steel and ferroalloys sector

    Steel and ferroalloysmanufacturing processes involve high temperature exhaust streams, often at more than 900ºC. Typically, the gas flows from the furnace (usually electric arch type) and goes into a gas conditioning tower to cool down below 200ºC so that it can be treated by a Bag Filter. It`s also common to have ESP´s as end dedusters that can be preceded by a multicyclone serving as pre-separators.

    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...

    Emission control solutions for clinker cooler and pre-heater dedusting sector

    The control of clinker fines emissions after the heatexchanger, placed downstream of the clinkercooler,is usually a problem for cementplant managers. The process is characterized by high material abrasiveness, high loads and variable flow ratein normal and maximum conditions.

    Emission control & air dedusting for Fertilizers

    The recovery of fertilizers typically after drying tunnels or drum dryers is associated with a high load of particulates and very humid gas streams. The recovery of these products is commonly performed by dryer cyclones as they allow for a direct powder capture and avoid filter clogging due to condensation. Arrangements with cyclones and/or with bag filters are usual in the industry.

    Emission control solutions for pyrolisis, incineration and gasification sector

    For PM emission control in very high temperature exhaust streams ( >600ºC ), such as gasification, pyrolysis and incineration, traditional bag filters following temperature exchangers, ceramic filters, or scrubbers are used as end stage dedusters. For most arrangements, a primary high temperature separator, namely a cyclone, is important to reduce as much ash and char as possible. A good efficiency is important to reduce concentration of solids to the final stage dedusters, avoiding plugging of scrubbers...

    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...
