2. 1. Development of low-cost ionic liquids based technology for CO2 separation

   Author : Chunyan Ma; Xiaoyan Ji; Päivi Mäki-Arvela; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Abstract : CO2 separation plays an important role to mitigate the CO2 emissions due to burning of fossil fuels, and it is also of importance in biofuel production (e.g. biogas upgrading and bio-syngas purification and conditioning). The solvent-based absorption is the state-of-art technology for CO2 separation, where various solvents, e. READ MORE

4. 2. Processing and characterization of membranes based on cellulose nanocrystals for water purification : Nanocellulose as functional entity

   Author : Zoheb Karim; Marielle Henriksson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

   Abstract : Membrane technology is being extensively used in water purification as an energy efficient and low cost process. Nanostructured (NSM) and nanoenabled (NEM) membranes are favored in this context as nanoscaled entities are expected to provide high surface area, high mechanical properties and versatile surface chemistry as well as provide better control on the pore size and distribution, flux and selectivity of the membrane.

5. 3. Integration of Aqueous Two-Phase Systems into Recovery Processes for Biomolecules

   Author : Cecilia Kepka; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteins; proteins; plasmid DNA; large-scale; protein purification; integration; Expression; aqueous two-phase systems; enzymology; Proteiner; enzymologi;

   Abstract : The main scope of this thesis has been to study and develop new purification methods and also to further develop existing methods for purification to enhance their efficacy. Important parameters in the development of the methods are that they should be suitable for scale-up and possible to be integrated into recovery processes. READ MORE

6. 4. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes

   Author : Hailong Li; Jinyue Yan; Umberto Desideri; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic property; vapour liquid equilibrium; density; equation of state; interaction parameter; CO2 mixtures; evaporative gas turbine; chemical absorption; oxy-fuel combustion; cost evaluation; CO2 capture and storage; Chemical engineering; Kemiteknik;

   Abstract : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

7. 5. Renewables Based Polygeneration for Rural Development in Bangladesh

   Author : MD. Ershad Ullah Khan; Andrew R. Martin; Semida Silveira; Peter Hagström; Jochen Bundschuh; Erik Ahlgren; Marcus Öhman; Monica Odlare; Lasse Aistrup Rosendahl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digester; solar PV; polygeneration; cooking gas; gas engine; electricity; membrane distillation; arsenic safe water; Anaerobisk rötkammare; solceller; polygenerering; matlagningsgas; gasmotor; elektricitet; membrandestillering; arsenikfritt vatten; Energy Technology; Energiteknik;

   Abstract : Despite the country's rural electrification programme, kerosene is the predominant source for lighting, and unsustainable and polluting woody biomass is virtually the only option available for cooking. The rural population also struggles with unsafe drinking water in terms of widespread arsenic contamination of well water. READ MORE
