    Particulate matter, halogens and aerosols

    Without CTP's innovative upstream systems, regenerative thermal oxidation would not be possible, which would render the waste gas purification cost-intensive and inefficient. Continuous burning off in the RTOs eliminates the deposits which periodically clog the ceramic honeycomb blocks.

    Very large waste gas volumes with low contaminant concentration

    The CTP desorption allows for an especially high concentration factor which, in turn, reduces the cost of ownership and permits an auto-thermal operation (additional burner switched off) even when the contaminant concentration is low.

    Thermal waste gas purification of siliceous organic compounds

    The cleaning problem of the heat exchangers was solved. The contaminants were destroyed efficiently and economically while steam for the production process was generated at no additional cost.

    Industrial air pollution control for the electronics and electrical industry

    The world`s appetite for electronic devices - from simple household appliances to sophisticated computers - has led to rapid growth of both these industries. Typically for the electronics industry, there are large waste gas streams (up to 400,000 Nm³/h) with relatively low concentrations of different solvents. The waste gases mainly occur in coating, cleaning and etching processes during the production of semiconductors, CDs/DVDs, Blue-ray discs, DVTs, TFT-LCD and plasma displays. The electronics industry has important standards to meet regarding environmental protection. CTP complies with these requirements: From zero emission goals, to installations on the roofs of production facilities.

    Air Pollution Control for Microelectronics

    ERG`s purpose-designed scrubbing systems are engineered to suit each application and client`s requirements. During the microelectronics boom years in the 1990s, ERG installed a variety of plants treating acid off-gases (HF, F2, HCl, Cl2, etc) with the capability to handle the sticky silanes formed from chlorosilane hydrolysis.

  • 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.

  • Shredders for Electric and Electronic Equipment (WEEE) and Refrigerators

    Electric and electronic waste (WEEE), are coming from technology products such as home appliances (washing machines, vacuum cleaners), computers and tools. An economy based on the consumption such as today, provides a continuous increase of WEEE, and determines an increasing risk of dropping out in the environment or in landfills, with the consequences of pollution of soil, air, water and health human repercussions. These products should be handled properly and used for the differential recovery of the materials they are made of, such as copper, iron, steel, aluminum, glass, silver, thus avoiding a waste of resources that can be reused to build new equipment in addition to the environmental sustainability.

  • Waste gas treatment for the TFT industry

    Manufacturing TFT/LCD displays requires waste gas treatment as well. Processes that produce large scale Thinfilm Transistors (TFT) on glass substrates, for instance, use Chemical Vapour Deposition – CVD – to separate the thin films onto the material. The process requires cleaning the process chamber periodically and usually employs etching with NF3. Etching of the separated thin films typically utilises CF4, SF6 and chlorinated gases, which release large amounts of waste gas mixtures.

  • 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.

  • 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.
