  2. 21. Carbon Recovery in A Dual Fluidized Bed Gasifier

    Author : Sébastien Pissot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

    Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE

  4. 22. Modelling and Simulation of the Fifth-Generation District Heating and Cooling

    Author : Marwan Abugabbara; Avdelningen för Installations- och klimatiseringslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste heat recovery; Heat pumps; 5GDHC; Modelica; Ethical risk analyses;

    Abstract : District heating and cooling are efficient systems for distributing heat and cold in urban areas. They are a key solution for planning future urban energy-efficient systems due to their high potential for integrating renewable energy sources. READ MORE

  5. 23. Evaluation of new active technology for low-energy houses

    Author : Henrik Davidsson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-quality heat; hybrid ventilation; heat recovery; active house; solar window; PV T hybrid; building integration; TRNSYS;

    Abstract : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. READ MORE

  6. 24. Studies on the Recovery of Secondary Antimony Compounds from Waste

    Author : Toni Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

    Abstract : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. READ MORE

  7. 25. Optimum Design of Heat Exchanger Networks in Retrofit Situations

    Author : Annika Carlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimum design; pressure drop; process integration; pinch thechnology; heat transfer coefficients; heat exchanger networks; retrofit;

    Abstract : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. READ MORE
