Development of hydrometallurgical reactor leaching for recovery of zinc and gold
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 16.12.2016)Hydrometallurgical methods offer promising techniques for resolving the challenge of producing metals essential to modern life in an environmentally and economically sustainable manner. Leaching has a central role in ... -
Experimentally validated numerical modelling of reacting multiphase flows in stirred tank reactors
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 12.04.2019)Homogenization of reacting flows by mixing is often important in order to achieve high reaction rates. Mechanical RANSagitation is the usual way to homogenize fluids used in industry. When supplied to fluid media, mechanical ... -
Gas-liquid mass transfer in bubbly flow: Estimation of mass transfer, bubble size and reactor performance in various applications
Acta Universitatis LappeenrantaensisURN:ISSN:1456-4491 (05.12.2005)Gas-liquid mass transfer is an important issue in the design and operation of many chemical unit operations. Despite its importance, the evaluation of gas-liquid mass transfer is not straightforward due to the complex ... -
Hydrodynamics and mass transfer in airlift bioreactors: experimental and numerical simulation analysis
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 19.12.2017)Airlift bioreactors are widely used in industrial applications such as wastewater treatment, gas decontamination and other biochemical processes, and such systems have generated increasing academic and industrial interest. ... -
Methanol synthesis via CO2 hydrogenation in a periodically operated multifunctional reactor
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 02.12.2022)Recognising the unsustainable nature of the current production practices, the global economy is now steering away from fossil energy sources. Although wind and solar energy have seen tremendous improvements over the past ... -
Power-to-methanol via membrane contactor-based CO2 capture and low-temperature methanol synthesis
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 04.12.2020)In the power-to-methanol concept, methanol acts as a platform chemical facilitating the integration of renewable electricity and captured CO2 into the fuel and chemical value chains, helping to substitute fossil resources ... -
Reactive crystallisation studies of CaCO3 processing via a CO2 capture process : real-time crystallisation monitoring, fault detection, and hydrodynamic modelling
Acta Universitatis Lappeenrantaensis (Lappeenranta-Lahti University of Technology LUT, 04.11.2022)Currently, a broad spectrum of decarbonisation efforts are ongoing in fundamental areas of human lifestyle to mitigate the global concerns materialising from climate-related transformations. Within the framework of carbon ... -
Towards sustainable production of value-added chemicals and materials from lignocellulosic biomass: carboxylic acids and cellulose nanocrystals
Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 02.11.2018)Industrial production of many chemicals and chemical products depends primarily on fossil resources. Lignocellulosic biomass, which is the most abundant and sustainable biomass on earth, is a potential renewable resource ...
