Reactor Chemistry and Chemical Processes Lab

Lab Objectives

• Study the dynamics of chemical reactors in series – Analyse the dynamic behaviour of perfectly mixed multi-stage reactions. – Observe how the conductivity of the solution changes along a series of reactors. – Understand the relationship between flow rate, residence time and conversion.
• Determine liquid and gas diffusion coefficients – Experiment with cells specifically designed for diffusion in the liquid phase (honeycomb) and the gas phase (heated capillary tube). – Gain skills in monitoring diffusion over time using conductivity meters and digital technologies. – Analyse the effect of temperature, concentration and pressure difference on diffusion.
• Analyse fluid mixing phenomena – Assess the effectiveness of mixing in stirred vessels with different impellers and at various speeds. – Study the behaviour of the drive torque during mixing. – Monitor fluid homogenisation visually and digitally as a function of the baffles.
• Explore heat transfer in stirred systems – Measure fluid temperature inside vessels using heated or cooled coils. – Calculate the change in viscosity and heat transfer performance. – Assess the impact of temperature on chemical reactions or mixing.

Educational Aims

• Develop a practical and theoretical understanding of chemical kinetics and mass transfer through real simulations.
• Train students in the use of advanced lab instruments: stirrers, conductivity meters, temperature sensors and graphing software.
• Foster the integration of physics, chemistry and engineering concepts in applied contexts.
• Develop skills in experimental analysis and data interpretation, including with digital tools and automatic acquisition.
• Prepare students for the world of the chemical industry and biotechnology, where mixing, diffusion and thermal control are fundamental processes.

Conclusion

The lab offers students a complete, structured programme on the fundamental principles of mass and heat transfer, reactivity and mixing in fluid systems. The activities allow not only qualitative observation of phenomena but also quantitative collection and analysis of data with advanced instruments and professional software. By carrying out experiments on diffusion, conduction, mixing and chemical reactions in series, students develop transferable skills that are useful both for continuing into higher education and for working in industrial, environmental and biotechnology settings. This lab experience therefore bridges theory and practice, promoting high-level technical, scientific and operational training. This solution includes technology that supports inclusion and equal opportunities through innovative teaching methods. It is designed to promote active, collaborative learning.
