Process intensification (PI) is transforming chemical, pharmaceutical, and specialty material manufacturing by merging reaction and separation steps, reducing energy consumption, and enhancing overall process efficiency. Traditional batch operations and multi-step separation processes often introduce inefficiencies, excessive energy demands, and material losses. Integrating thin-film evaporation with other advanced thermal separation techniques—including distillation, stripping, and rising/falling film evaporation—offers scalable, modular solutions that optimize product purity and yield.

This presentation focuses on thin-film evaporators (TFEs) as core technology for solvent recovery, post-reaction stripping, and continuous processing. TFEs are particularly advantageous for handling heat-sensitive, high-viscosity, and thermally unstable compounds. A comparative analysis demonstrates how TFEs outperform conventional technologies (e.g., batch distillation and rotary evaporators) in energy efficiency, separation effectiveness, and scalability.

Beyond thin-film evaporation, the discussion will extend to innovative thermal separation strategies that combine multiple unit operations to create highly intensified processes. The integration of distillation, stripping, and falling film evaporation with thin-film technology enables process designers to minimize footprint, reduce equipment redundancy, and maximize throughput. Real-world industrial applications in pharmaceutical solvent recovery, bio-based chemical purification, polymer processing, and petrochemical refining will be presented, demonstrating the advantages of hybrid separation approaches.

A key focus will be on how process intensification principles can be leveraged to overcome common scale-up challenges, such as residence time distribution, heat transfer limitations, and thermal degradation risks. Attendees will gain insights into the latest design advancements, energy optimization techniques, and modular system innovations that enable seamless scale-up from laboratory to commercial production.

By combining thin-film evaporation with other intensified separation techniques, this presentation provides a comprehensive framework for designing high-efficiency, sustainable, and economically viable separation processes. The findings will serve as a practical guide for engineers and decision-makers looking to implement cutting-edge process intensification strategies to enhance yield, reduce operational costs, and achieve superior product purity.
