  • Waste Gas in Metal Recycling: Hydrocarbons and carbon monoxide - Case Study

    Waste Gas in Metal Recycling: Hydrocarbons and carbon monoxide - Case Study

    Example: Aluminium recycling Similar tasks: Recycling of copper, lead, cink The waste gas in metal recycling usually contains particles (abraded metal, mineral dust), inorganic, acid substances (HF, HCI, SOx) and dioxins (PCDD/F) as well as a ...

  • Nitrous oxide (laughing gas) - Case Study

    Nitrous oxide (laughing gas) - Case Study

    Example: Uranium enrichment Similar tasks: Nitric acid caprolactam production When uranium ore is converted into uranium hexafluoride (UF6) for uranium enrichment employing the diffusion process, or also when producing nitric acid and nitrogenous ...

  • Extraction of many emission sources in extensive factory premises - Case Study

    Extraction of many emission sources in extensive factory premises - Case Study

    Example: Packaging Similar tasks: Coating, Automobile industry, paint production Different production processes lead to decentralised ventilation of emission sources. These decentralised ventilations are consolidated within a central air pollution ...

  • Thermal waste gas purification of siliceous organic compounds - Case Study

    Thermal waste gas purification of siliceous organic compounds - Case Study

    Example: Electrical industry Similar tasks: Electronic industry, Coating, Waste management When coating mica insulation materials, peaks of high contamination occur. The exhaust air containing organic compounds generates excess heat when oxidised ...

    Example: Waste disposal for tanneries Similar tasks: Leather industry, fish cannery, bio-ethanol production, coffee roasters Various leather producers operating a tannery founded a joint waste disposal company which produces valuable proteins from ...

  • Particulate matter, halogen and aerosols - Case Study

    Particulate matter, halogen and aerosols - Case Study

    Example: Production of anodes for aluminium smelters as well as electronic industry (TFT-LCD) Similar tasks: Carbon and graphite industry, smelting of aluminium, coating of metals An anode producer has several ring furnaces to stabilise the anodes ...

  • Dioxines and furanes - Case Study

    Dioxines and furanes - Case Study

    Example: Scrap copper recycling, cobalt for battery production Similar tasks: Metal recycling, roast processes, thermal waste disposal When recycling metals - as in scrap copper recycling (mostly cable material) - toxic waste gases often occur. The ...

  • Particles and alkaline compounds - Case Study

    Particles and alkaline compounds - Case Study

    Example: Refining of bauxite Similar tasks: Metallurgy The production of aluminium oxide during the Bayer process - as a raw material for the aluminium industry - is done by refining the bauxite with sodium hydroxide solution. For better economic ...

  • Humid, corrosive and malodorous waste gases - Case Study

    Humid, corrosive and malodorous waste gases - Case Study

    Example: Production of bio-ethanol Similar tasks: Dryers, Fibre board industry The production of bio-ethanol - fermentation, distillation, pelleting and drying - generates odorous and humid waste gas. Upstream lamellar demisters reduce both drop ...

  • Several waste gas streams: Highly contaminated oxygen-free waste gas, and medium waste gas stream - Case Study

    Several waste gas streams: Highly contaminated oxygen-free waste gas, and medium waste gas stream - Case Study

    Example: Chemical industry Similar tasks: Petrochemical and pharmaceutical industries A producer of synthetic rubber creates a medium waste gas as well as a highly contaminated oxygen-free waste gas which contains primarily low hydrocarbons. The ...

  • Chlorinated hydrocarbons - Case Study

    Chlorinated hydrocarbons - Case Study

    Example: Pharmaceutical industry Similar tasks: Chemical industry The Pharmaceutical industry uses different processes to create chlorinated hydrocarbons. In a regenerative thermal oxidiser (RTO) the chlorinated organic contaminants are destroyed ...
