In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.
The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a...
Ventilation Air Methane (VAM) is a Greenhouse Gas (GHG) released by coal or mineral mining operations, it is also commonly known as Coal Mine Methane (CMM). The air pollutants from this process have a global warming potential 21 times greater than carbon dioxide, which is another well known GHG. As alternative energy technologies have developed, methane is increasingly used to generate electricity and heat. Landfills and mines represent two of the most abundant sources, however reports indicate that more than...
Achieving cost effective local regulatory compliance in the printing and converting industry requires a complete understanding of both regulatory standards and the printing process. Through experience, Anguil has developed unparalleled expertise in meeting your unique requirements. We understand the effects of water versus solvent-based inks on the line, elimination of odors and toxic fumes from dryers and oven tunnel exhausts, and the capture of fugitive emissions. Over 300 successful printing installations...
For processes where plastics are molded or extruded (as evidenced by a “hazy” exhaust plume at the stack) scrubbers are used to treat the sub-micron particulates and oil mists generated. Certain other processes (e.g. Fiberglass Reinforced Plastic equipment fabrication) emit VOCs that can be captured with absorption.
The primary metals manufacturing industry includes aluminum production. A variety of clean air solutions are required for capturing, conveying, and collecting emissions from aluminum rolling mills, including fume exhaust, ventilation and process cooling systems. The aluminum industry also requires technologies for product recovery, along with dampers and expansion joints, and pumps and valves.
The metal plating line is the part of the metal finishing process where metal is applied to a substrate. Metal plating involves many complex processes related to reducing contamination of the process bath; ensuring regular monitoring of bath chemistry; wetting agents; anodes; purified water; ventilation and exhaust systems; acid solution regeneration; and spent acid bath reuse.
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.
The primary metals manufacturing industry includes iron & steel production. A variety of clean air solutions are required for capturing, conveying, and collecting emissions from steel rolling mills, including fume exhaust, ventilation and process cooling systems. The iron & steel industry also requires technologies for product recovery, along with dampers and expansion joints, and pumps and valves.
Cement manufacturing has an impact on the environment at every stage of the manufacturing process. Airborne pollutants are released in the form of dust, gases, noise, and vibration when operating machinery and during blasting in quarries. Technologies to reduce dust emissions during the quarrying and manufacture of cement are widely used, as are technologies to trap and separate exhaust gases.
Plants within the semiconductor and circuit manufacturing industry deals manufacture semiconductors, computers, printed circuit boards, and other very small electronic components, including transistors, capacitors, inductors, resistors, diodes, insulators and conductors. Semiconductor manufacturing process emissions and pollution control challenges include VOC abatement; acid gas scrubbing; fluid handling; filtration; and laboratory fume hood exhaust.
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.
In the mineral processing industries, such as calcination or catalysts production, solid intermediates and products are regularly handled in the fine powder form. There is a need to recover these powders from the exhaust streams of calciners, fluid bed dryers, incinerators, and storage silos, often at critical temperature conditions. Client`s needs include an efficient cyclone either for minimizing the escape of particles to downstream sections of the process at very high temperatures or to recover the maximum...
In calcination processes, solid intermediates and products are regularly handled in the fine powder form (ex: kaolin or metakaulin). There is a need to separate these very fine powders from the exhaust streams of calciners, fluid bed dryers or incinerators, often at critical temperature conditions. For PM emission control at very high temperature ( >600 ºC), traditional bag filters following temperature exchangers or scrubbers are used as end stage dedusters.
