Klas Andersson

Full Professor at Energy Technology

Klas Anderssonis is professor of Combustion and CO2 Capture Technologies. His research is focused on chemistry and transport phenomena in combustion and CO2 capture processes. The work is based on experimental and theoretic research which aims to provide generic knowledge on combustion and gas cleaning technologies. The overall objective is to contribute to a reduction of the environmental impact associated with the use of energy in various industrial applications. An important part of the research concerns new processes and solutions which can be employed to achieve drastic reductions in CO2 emissions, in particular CO2 capture technologies. The studied applications are mainly industrial and heat and power generation processes.
