    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...

    Continuous emissions monitoring for sulphuric acid production plants

    The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.

    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...

    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.

    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.

    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 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.
