Chemical Technologies for Industry Lab

Lab Objectives

• Study the kinetics of batch enzymatic reactions – Analyse the isomerisation of glucose into fructose catalysed by glucose isomerase. – Observe the effect of operating variables such as temperature, concentration and time on the reaction rate.
• Develop skills in using optical instruments for continuous monitoring – Understand the principle of the optical flow polarimeter for determining sugar concentration. – Interpret data from integrated digital devices (rotation angle of polarised light, reaction curve).
• Apply process control and automation methods – Use a PID controller to regulate the temperature in the reactor. – Implement a system for automatic sampling and real-time monitoring of reactions.

Educational Aims

• Explore batch enzymatic catalysis in depth through a teaching plant that faithfully simulates industrial operating conditions.
• Become familiar with automated analytical instruments, in particular optical analysis devices (polarimeter) and integrated control systems.
• Encourage an interdisciplinary approach across biochemistry, chemical engineering and process control, building the ability to read experimental data critically.
• Get students used to software for recording and plotting data, making it easier to manage and interpret experimental information from an industrial perspective.

Conclusion

The batch enzyme reactor lab is an important learning experience for understanding the basics of biological catalysis, enzyme kinetics and automated measurement techniques. Combining a chemical process, advanced instruments and control software gives students the opportunity to work in a setting similar to industry, with a high degree of operational fidelity.
