Chemical process engineering
Chemical Process Engineering is the branch of engineering science which focuses on the transformation of low-value raw materials into high-value goods supporting the everyday life of people, such as food, drugs, fuel, automotive and packaging materials, fabrics, adhesives, bio-compatible materials (e.g. contact lenses, implants and prosthetics). This transformation typically requires a number of physical steps (separation and purification processes) and chemical steps (chemical reactions), which need to be combined in an optimal way to give the desired products with minimal consumption of raw materials and energy, minimal impact on the environment and safety for the operators. Chemical Process Engineering is the scientific area focusing on conceptual, equipment, control and monitoring aspects of both single process units (separation units and chemical reactors) and their overall combination. The unitary principles of Chemical Process Engineering find therefore application in a wide range of industries, spanning from traditional to new areas.

The department of Chemistry and Bioscience has built world class laboratory facilities in collaboration with industry. This include excellent research infrastructures in within the area of chemical process engineering.
Highlighting some of our core equipment:
SITEC PVT cell
PVT-cell with a variable volume (11-61 ml) and full visualization of the sample volume this PVT-cell allows for studies of phase equilibria in the range from ambient condition to 500 bar and 200 oC.
Raman RXN1 spectrometer (Kaiser Optics, Ltd) with 785 nm laser, fiber connection and several probes allowing to acquire spectra with (immersion probe) and without (non-contact probe) interaction with samples. Can be used for solid and liquid samples as well as with powders.
SITEC CO2 Extractor
Supercritical CO2 extractor with a volume of 345 ml and operating range from ambient to 500 bar and 200 oC. Applicable for the use of supercritical CO2 as a benign solvent compared to conventional organic solvents.
SITEC Biomass reactor
This 99ml reactor system is designed for injection of water and slurries into an already heated reaction chamber to allow for fast heating of reactants. This novel design allows for investigation of reactions in near and supercritical water with a much better control of pressure, and reaction time than traditional batch reactors. Operating window is ambient to 300 bar and 400 oC.
Several NIR spectrometers including lab scale Quant (Q-Interline) which can work both for reflectance and transmittance in the range of 1000-2500 nm and two handheld spectrometers from Hyspex (900-1800 nm and 1800-2500 nm)
