1. 11. Developments in Feedstock Analysis and Process Control for Biogas Production

   Författare :Sten Strömberg; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

   Sammanfattning : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. LÄS MER

3. 12. Software Process Assessment & Improvement in Industrial Requirements Engineering

   Författare :Tony Gorschek; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Process Assessment; Process Improvement; Requirements Engineering; Abstraction; Requirements; SPI; RE;

   Sammanfattning : Requirements Engineering (RE) is a crucial part of any product management and product development activity, and as such deficiencies in the RE process may have severe consequences. There are reports from industry that point towards inadequate requirements being one of the leading sources for project failure. LÄS MER

4. 13. Continuous Ethanol Production from Dilute-acid Hydrolyzates: Detoxification and Fermentation Strategy

   Författare :Ronny Purwadi; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMF; serial bioreactor; immobilization; overliming; furfural; ethanol; continuous cultivation; S. cerevisiae; flocculating yeast; continuous detoxification; dilute-acid hydrolyzate;

   Sammanfattning : The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. LÄS MER

   Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER

7. 15. Fabriken som kulturarv : Frågan om industrilandskapets bevarande i Norrköping 1950-1985

   Författare :Annika Alzén; Linköpings universitet; []
