Chemical Process Systems Engineering & Process Intensification (CPSE&PI)

The research focuses on the development of new manufacturing methods and processes. One important research topic is related to carbon neutral and carbon negative process development, especially Power-to-X theme (https://www.lut.fi/web/en/research/platforms/reflex). Other key topic areas in this sector include intensification of processes, modelling and simulation, design methodology, process safety and development of new process units, especially multiphase processing equipment.

Process intensification is currently one of the most important trends in chemical engineering. It aims at making manufacturing processes more efficient. New, intensified processes are usually more efficient, smaller in size, combining different technologies and often also safer and more eco-friendly.  Innovation is key in the field of intensification. Process intensification does not refer to incremental improvements to processes, e.g. computational optimization, but rather to rethinking of the entire process. Fundamental to this is understanding of process behavior through chemical process modelling and simulation tools.

LUT Chemical Process Systems Engineering & Process Intensification (CPSE&PI) is actively involved in process intensification (https://efce.info/WP_PI.html), both in the development of methods and practical applications.

General themes of the Research Group

  • Physicochemical phenomena based process modelling
  • Simulation of larger process entities
  • Process Intensification: experimentation and modelling

Accomplishments and expertise of the Research Group

  • Applying CFD (Computational Fluid Dynamics) in chemical processes: Measurement and modelling of local gas-liquid mass transfer in bioprocesses
  • Parameter estimation and uncertainty quantification: Dynamic modelling in the leaching of gold and other metals
  • Machine-vision based measurement methods: rotating drum fluid dynamics, local concentration topology inside particles (droplet).
  • Development of risk analysis methods: handling of nanotube materials
  • Carbon neutral/negative process development: carbon dioxide capture using membrane contactors, methanol production from CO2, kinetic modelling of carbon dioxide hydrogenation phenomena
  • Development of continuous, intensified crystallization processes
  • Wet oxidation of bio-based side streams

The main areas of the research are related to carbon footprint reducing applications: carbon capture, chemical production using renewable energies, recovery of valuables from biomasses and bio-based side streams.

Educational activities

  • Courses in process design and intensification, process simulation and analysis, and CFD (Computational Fluid Dynamics) modelling. They support research methods and skills needed in process industries as well as skills needed in academic research.
  • Supervised Bachelor and Master theses are from industrial topics in process industries and from the cutting-edge research projects carried out within the research group. Large part of graduated chemical engineers at LUT are closely connected the topics from our research group.
