Formaldehyde serves as a key feedstock for various substances, including plastics and renewable fuels. Traditional production methods are highly energy-intensive due to the requirement for high-temperature conditions. Typically, formaldehyde is produced in an aqueous solution and concentrated through distillation, utilizing well-established and state-of-the-art technologies. At the Laboratory of Chemical Process Engineering, we are studying the effects of different electrolytes on the liquid-liquid equilibrium (LLE) of formaldehyde-water-alcohol solutions. The collected data will be used to develop a phase equilibrium model that accurately accounts for the presence of these substances. The successful candidate will play a crucial role in advancing this sustainable production method.

Requirements
• High interest and prior knowledge of laboratory analytical work desirable.
• Basic knowledge of thermodynamics and phase equilibrium.
• High degree of independence and personal responsibility.

Tasks
• Familiarization with the formaldehyde systems, and experimental set-up.
• Designing and conducting liquid-liquid equilibrium (LLE) and vapor-liquid equilibrium (VLE) measurements.
• Fitting experimental data to model phase equilibrium.

What You Will Gain:
• Hands-on experience in experimental design and data analysis.
• Knowledge in extraction processes and downstream chemical engineering.
• Experience with GC, IC, and different analytical methods
• Opportunity to contribute to an energy-efficient industrial process.
