Model based analysis of the post-combustion calcium looping process for carbon dioxide capture
(Lappeenranta University of Technology, 2013-12-09)
This thesis presents a one-dimensional, semi-empirical dynamic model for the
simulation and analysis of a calcium looping process for post-combustion CO2 capture.
Reduction of greenhouse emissions from fossil fuel power ...
Comprehensive Study of Crystal Growth from Solution
(2004)
Crystal growth is an essential phase in crystallization kinetics. The rate of crystal growth provides significant information for the design and control of crystallization processes; nevertheless, obtaining accurate growth ...
Item-level life-cycle model for maintenance network – from cost to additional value
(Lappeenranta University of Technology, 2015-12-11)
The importance of industrial maintenance has been emphasized during the last decades;
it is no longer a mere cost item, but one of the mainstays of business. Market conditions
have worsened lately, investments in production ...
Analysis of sorption-enhanced gasification for production of synthetic biofuels from solid biomass
(Lappeenranta-Lahti University of Technology LUT, 2021-12-01)
Anthrophonic greenhouse gas emissions have led to climate change. The transportation sector is one of the most significant greenhouse gas emitters. Mitigation of carbon dioxide (CO2) emissions from transportation is a great ...
