1. 11. Impacts of Thermo–Physical Properties on the Design, Operation, and Cost of Monoethanolamine–Based Chemical Absorption

   Författare :Worrada Nookuea; Jinyue Yan; Eva Thorin; Hailong Li; Xiaoyan Ji; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The thermodynamic and transport properties of CO2 mixtures are essential to the design, operation, and optimization of all carbon capture and storage processes. To retrieve accurate property values, accurate property models are required. However, there are many properties, which are in turn affected by many factors. LÄS MER

3. 12. Tailoring of adsorptive properties of zeolites for biogas upgrading

   Författare :Kritika Narang; Farid Akhtar; Andreas Kaiser; George Shimizu; Chrystelle Salameh; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

   Sammanfattning : Biogas is a promising alternative fuel with low CO2 emissions and high market potential due to the abundance of organic biomass. Despite being a renewable form of energy, biogas consists of 40-45% CO2, which lowers its calorific value [1]. LÄS MER

4. 13. Analysis of drying wood based on nondestructive measurements and numerical tools

   Författare :Jonas Danvind; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

   Sammanfattning : Improved understanding of moisture and mechanical behaviour is a general objective for wood drying research. The main objective of this doctoral thesis was to develop nondestructive experimental methods suitable for collecting valuable response data related to the moisture behaviour and mechanical behaviour of drying wood and to refine this information into modelling parameters.

5. 14. Seasonal snow storage for space and process cooling

   Författare :Kjell Skogsberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

   Sammanfattning : The world’s cooling demand has increased considerably during the last decades due to increased population, industrialisation, comfort demands, electronic equipment usage and new building technologies. Conventional cooling is often produced by electrically driven devices. LÄS MER

7. 15. Modelling of dynamic and quasistatic events with special focus on wood-drying distortions

   Författare :Mats Ekevad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : This thesis deals mainly with computer simulations of wood-drying distortions, especially twist. The reason for this is that such distortions often appear in dried timber, and the results are quality downgrades and thus value losses in the wood value chain. LÄS MER
