Development of structured catalyst and reactor technologies for biomass conversion - Continuous production of sugar alcohols
(Åbo Akademi University, 2021-05-19)
Energy-efficient technologies have been an aspiration for chemical industries, especially the design of chemical reactors. Structured catalysts play an important role to achieve this purpose. Several types of structured ...
Lipase catalyzed chemo-enzymatic epoxidation of fatty acids using ultrasound as a process intensification method
(2021)
The recent trend in switching from fossil to renewable sources in the production of essential chemicals has revealed novel methods within the concept of green chemistry. This work focuses on the epoxidation of oleic acid ...
Effect of Dust Sintering on Fouling of Recovery Boiler Flue Gas Ducting
(2021)
Recovery boilers today are 100 times the capacity of the original design. The fuel, black liquor, used in recovery boilers has also changed. To improve the efficiency of the boiler, the fuel contains less water. Increased ...
Degradation of polydimethylsiloxane in simulated industrial process environments
(2021)
Polydimethylsiloxane (PDMS) is commonly used in the Kraft process as an anti-foaming agent, which is added during the pulp-washing stage, where the pulp is separated from the black liquor. Crude tall oil (CTO) is later ...
A Study of Glucose Transformation to Lactic acid and Methyl lactate
(2021)
Lactic acid and methyl lactate are platform molecules that hold great potential within the biorefinery industry. They are currently produced through a combination of enzymatic and fermentation processes within the industry, ...
Inventory and management of process wastewater streams in a pharmaceutical production plant in Finland
(2021)
Pharmaceuticals and their effects on the environment have become continually a more and more interesting topic. Even though only 2% of all European API (Active Pharmaceutical Ingredient) discharges are from the pharmaceutical ...
Project and portfolio cash flow development
(2021)
Efficient cash flow management is vital for the survival and long-term success of every company. The nature of the construction business often forces contractors to work with less internal financing and trust that customer ...
Monomers from vegetable oil feedstock : kinetics, catalysis and thermal risk
(Åbo Akademi University & Institut National des Sciences Appliquées de Rouen, 2021-07-09)
Polyurethanes are among the most important polymers in our everyday life, they are industrially produced via the reaction of polyols and di-isocyanates. This process present multiple severe drawbacks such as high toxicity ...
