1. 11. Interaction between defossilisation of basic industries and relocation : Scenario-based explorative and normative transition pathways to electrification for European basic industries and specific clusters

   Författare :Clemens Schneider; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel; petrochemicals; defossilisation; climate-neutral production; electrification; industry clusters;

   Sammanfattning : The steel and chemical production industries are the largest industrial emitters of greenhouse gases in the European Union, together accounting for half of the EU’s industrial greenhouse gas (GHG) emissions. A promising strategy for achieving deep GHG emissions reductions is the electrification of these two industries, which would depend on the rapid expansion of renewable electricity supply. LÄS MER

3. 12. Partial carbon capture – an opportunity to decarbonize primary steelmaking

   Författare :Max Biermann; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; amine absorption; partial CO2 capture; process industry; cost estimation; CCS; steel making;

   Sammanfattning : Climate change requires that all energy-related sectors drastically reduce their greenhouse gas emissions (GHG). To have a high likelihood of limiting global warming to 1.5°C, large-scale mitigation of GHG has to start being implemented and cause emissions to fall well before Year 2030. LÄS MER

4. 13. Closed-die forging and slab hot rolling with focus on material yield : some industrial problems analysed by FEM

   Författare :Esa Ervasti; Ulf Ståhlberg; Hans Keife; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material yield; Closed-die forging; Hot rolling; Cracks; Macro-inclusions; Steel; FEM; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : The thesis is focussed on improving the material yield in closed-die forging and rolling. The former is restricted to the manufacturing of heavy crown wheels and front axle beams and the latter to the hot rolling of steel slabs. To enhance the yield the commercial FE-codes Form2D and Dyna3D are used. LÄS MER

5. 14. Planning production and supply chain in energy intensive process industries

   Författare :Martin Waldemarsson; Helene Lidestam; Martin Rudberg; Magnus Karlsson; Sophie D'Amours; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Energy-intensive production processes; Energy system; Energy management; Production planning; Supply chain planning; Case studies; Mixed Integer Linear Programming; Modelling; Specialty chemicals; Pulp; Steel;

   Sammanfattning : To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users.

7. 15. Conjoint analysis as a tool for communication and corporate environmental decision-making

   Författare :Stina Alriksson; Tomas Öberg; Marianne Lindström; Högskolan i Kalmar; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conjoint analysis; PLS; Cluster analysis; Communication; Environmental; Decision-making; Environmental engineering; Miljöteknik; Miljövetenskap; Environmental Science;

   Sammanfattning : Conjoint analysis has been used extensively in marketing, transportation and healthcare for the past 50 years. Since the mid-1990s, it has also been applied to an increasing number of environmental issues. In this thesis, conjoint analysis is applied to environmental objectives of the Swedish steel industry.
