  • Waste gas treatment for the LED industry

    Market analysts predict sustained growth in demand in the LED industry. After LED backlighting for the small LC displays of mobile phones and the LC displays of larger screens in the television market, the next potential growth market is the lighting industry: Sales of LEDs in this market in 2012 are almost USD 3.5 billion – thus nearly doubling since 2010. Analysts are expecting a growth of more than USD 7 billion in 2014 and believe that the total market for LEDs should peak at USD 17.7 billion.* A mass market of this scale for LEDs also means increasing emissions that need to be abated by specific waste gas treatment systems at the point of use. In the manufacture of products based on innovative light emitting diode (LED) technology, ammonia and hydrogen are used in large quantities as process gases. The environmental engineers at DAS have recognised this market trend and developed new solutions such as LARCH for waste gas treatment in MOCVD processes.

  • Waste gas treatment for the semiconductor industry

    In the early 1990s no appropriate and comprehensive technical solution had been available for waste gas treatment in the semiconductor industry. Back then as well as today many industrial and research production procedures use process gases and generate waste gases. These waste gases, considered greenhouse gases, are toxic and/or highly flammable and very often pose a significant risk to production facilities and the environment. The semiconductor industry, for instance, uses perfluorocarbons, whose global warming potential is extremely high and therefore requires an efficient waste gas treatment. Combining and transporting different gases into a fab’s central waste gas system might produce highly flammable and highly explosive gaseous mixtures, which in the past has occasionally caused the total loss of entire production facilities. Particles contained within gases may also cause exhaust blockages. To eliminate these risks, process waste gases need to be treated at the “Point-of-Use” (POU) where harmful exhausts are abated immediately.

  • Oxygen Generating Systems for Waste Gas Treatment in the Semiconductor, PV and LED Industries

    Waste gas treatment is an often overlooked but important function of Semiconductor, PV and LED fabrication. Several serious accidents have taken place in factories where no abatement was installed. Even today waste treatment is often seen as a cost rather than a safety issue. There are three main reasons why waste gas treatment is installed in factories: health and safety, environmental factors, and quality control.

    High quality gas sensor solutions for landfill

    State-of-the-art systems enabling easy monitoring of CO2 and CH4 gases. Capped Landfill Sites produce a range of gases, mostly methane and carbon dioxide. Legislation requires that these gases are safely removed from beneath the cap to avoid a physical explosion due to the build-up of pressure beneath the cap. Safe disposal usually entails burning such as flare stacks, internal combustion engines or by processing to produce Methane gas fuel. For large sites with access to power distribution infrastructure internal combustion engines are used to generate electricity which is fed into the local electricity grid. All of the above safe disposal process require the measurement of the Methane content (and in many cases the CO2 concentration). Edinburgh Sensors provide gas sensors for both Methane and CO2 that can be integrated into landfill gas processing systems enabling easy monitoring of these gases.

    Gas monitoring instruments and systems for anesthetic gases

    The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.

    Several waste gas streams: Short, high concentration peaks and a constant |medium concentration

    Concentration peaks and liquid waste posed a tough challenge on the air pollution control system. With the CTP solution, this waste is not only disposed of but also reduces the burner energy considerably.

  • High performance solid-liquid separation system for deepwell industry

    Deepwell facilities for the disposal of plant waste streams often employ nominally rated spray spun elements, bags, diatomaceous earth filters, and various other types of conventional filtration technology. These labor intensive systems provide protection of the well from occlusion by suspended particle matter, albeit often with high operational cost and limited assurance of reliable fluid quality. The ongoing challenge facing a deepwell system is the requirement that the formation into which the waste is being pumped must maintain its porous nature in order to operate effectively. Therefore, reliable, effective filtration to capture particles with the potential to plug the formation is critical. Pentair Porous Media’s proven advanced separation technologies have been employed in deepwell disposal systems to enhance system reliability, assure well integrity and lower operating costs and system maintenance.

    Waste recovery for glass manufacturing

    Tetronics` twin torch system has been used continuously for the commercial production of high quality silica glass for optical applications since 1992. Tetronics’ unique twin torch technology allows a plasma arc to be created in space, which enables a falling stream of high quality silica powder to be melted at the junction of the two arcs to form an ingot of high optical quality silica glass. By using plasma as a clean and controllable heat source, the product has a high degree of integrity, because the absence of a natural gas flame means the resulting product is free from bubbles, contamination and other defects.
