1. 1. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency

   Författare :Christer Sandberg; Per Engstrand; Jan-Erik Berg; Göran Bengtsson; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This work shows that, for newsprint quality grades, the production processes for mechanical pulp can be simplified, and the specific electrical energy demand can be reduced with around 600 kWh/ton (30%). The purpose of the work is to demonstrate how the production cost for mechanical pulps can be decreased through increased energy efficiency and reduced number of unit operations. LÄS MER

   Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process control; process intensification; heat exchange reactor; mid-ranging control; extended Kalman filter; model predictive control;

   Sammanfattning : The focus of this thesis is on modeling and control of the Open Plate Reactor (OPR), a new heat exchange reactor being developed by Alfa Laval AB. It combines intensified mixing with enhanced heat transfer capacity into one operation. LÄS MER

7. 5. Intensification of the biogas process by improved process monitoring and biomass retention

   Författare :Lovisa Björnsson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOD; hydrogen; on-line; monitoring; biofilm; anaerobic digestion; biogas; Biotechnology; Bioteknik;

   Sammanfattning : The utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. LÄS MER
