Our research areas:

  1. Techno-economic assessments of plant scale processes

  2. Process and plant design for bio-based, sustainable products

Research:

The research in Plant Design focuses on process feasibility study, synthesis, design, operation, integration, simulation and optimization, as well as  inherent safety, occupational health, pollution prevention and industrial risk. The key theme is the development of systematic methodologies to identify optimum, sustainable and creative strategies that lead to process intensification, yield improvement, debottlenecking, costing, safety, pollution prevention and energy conservation. Fundamental chemical engineering principles are coupled with systems engineering approaches to develop methods and computer-aided tools that are applicable in all areas of chemical process industry.

Current research projects:

1. LignoSphere -spherical lignin particle as a platform material for sustainable adhesives and beyond:

Within the forest industry there is high interest in converting lignin into high value added products. We aim to convert industrial lignin side-stream into value-added products.

4. SO4 Control:

Mining waters contain often sulfates in excessive amounts. The target is to convert sulfates to sulfides by bioreaction and separate the gases produced (CO2, H2S).

5. Modeling and scale-up of centrifugal filtration:

The project is planned to aid the industry, especially pharmaceuticals field, to make better investments and have better abilities to represent their scenarios computationally without the need to experiment in large scale production.

Education:

The education in Plant Design is directed at process design and development methods in B.Sc, M.Sc and Ph.D levels. This includes preliminary process design, process synthesis, cost engineering, process simulation and environmental and safety aspects of design. This knowledge can be used for the development of new processes, engineering of new plants and improvement of existing ones in the chemical, petrochemical, biofuel, pulp and paper, minerals, food and biotech and pharmaceutical industries. The teaching is based on problem-based learning, in which process design and development problems are solved using modern design tools such as simulation programs and other design methods. The teaching also includes advanced practical design projects performed as group work and guided by industrial engineers from appropriate companies.
