  1. 1. Acid retardation : recovery and recycling of acid and metal

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Cecilia Bood; [2020]
    Keywords : Acid retardation; Ion exchange; Pickling; Stainless steel;

    Abstract : During the production of steel, an oxide scale is formed on the surface and to achieve anadequate quality of the surface the scale needs to be removed. Acid pickling is a surfacetreatment where the oxide scale is removed by acid. READ MORE

  2. 2. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Per Kautto; [2020]
    Keywords : palladium ceramics; silver smelting slag; PbO-SiO2-Sb2O3;

    Abstract : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. READ MORE

    University essay from KTH/Industriell ekonomi och organisation (Inst.); KTH/Maskinkonstruktion (Inst.)

    Author : Melika Abedi; Elin Thun; [2020]
    Keywords : Stainless Steel Industry; Metal Recovery; Sustainability; Material Reuse; Circular Economy; Customer Value; Pricing Management; Pricing Models; Value-Based Pricing; Rostfria Stålindustrin; Metallåtervinning; Hållbarhet; Materialåteranvändning; Cirkulär Ekonomi; Kundvärde; Prishantering; Prissättningsmodeller; Värdebaserad Prissättning;

    Abstract : As the stainless steel industry continues to grow, so does the environmental impacts generated by the various production processes. Such impacts not only affect the environment but pose great health concerns for humans and other living things. Therefore, it is necessary for all stakeholders to continuously improve their sustainability work. READ MORE

  4. 4. Theoretical and Experimental Characterizationof a Soft Polymer Heat Exchanger forWastewater Heat Recovery

    University essay from KTH/Energiteknik

    Author : Sixiang Lyu; [2020]
    Keywords : polymer heat exchanger; wastewater; heat recovery; heat transfer enhancement; oscillation i; polymervärmeväxlare; avloppsvatten; värmeåtervinning; förbättring av värmeöverföring; svängning;

    Abstract : Wastewater released from showers, sinks, and washers contains a considerable amount of wasteheat that can be recovered by using a heat exchanger. Conventional metal heat exchangers for wastewater heat recovery have common problems of corrosion, fouling and clogging, which makes it necessary to develop a new type of heat exchanger for such low-grade thermalenergy recovery applications.

  5. 5. An investigation of some properties of Shredder Fines and an element analysis of its ash to find new ways of dealing with this waste

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Adeel Naidoo; [2020]
    Keywords : Shredder fines; Bottom ash; Ash analysis; Combustion; Chemical fractionation; Elemental analysis; Cement industry; Metal recovery;

    Abstract : Shredder fines are the materials with a particle size of less than 10 mm resulting from the shredding of vehicles and complex metal scrap from industries and municipalities. This waste is currently used as landfill construction material, but Stena Recycling wanted to know whether the bottom ash from the combustion of this waste could be useful to the cement industry, and whether it would be feasible to extract Cu and Zn from this ash.
