What types of chemistries are suitable for continuous flow?

Continuous flow is well-suited for reactions that benefit from precise temperature and residence time control, such as nitrations, hydrogenations, photochemical reactions, and multi-step telescopic sequences. The suitability is assessed on a case-by-case basis during the initial feasibility review.

How do you handle heterogeneous or gas-liquid reactions?

We have experience with slurry and gas-liquid reactions using specialized reactors such as continuous stirred-tank reactors (CSTRs) and tubular reactors with static mixers or gas injection modules. The optimal configuration is scoped per project to ensure efficient mass transfer and reaction control.

Can you integrate in-line analytics?

Yes, we routinely integrate Process Analytical Technology (PAT) such as FTIR, Raman, and UV-Vis spectroscopy for real-time monitoring of reaction progress and product quality. The specific analytical method is selected based on the chemical system and project requirements.

How do you ensure scalability?

Scale-up is achieved through either identical geometry scale-up (increasing tube diameter while maintaining flow regime) or numbering-up (parallel reactor channels). Our modular skid designs facilitate direct transfer from lab to commercial production scales, with process parameters documented in the technology transfer package.

What documentation do I receive?

You receive a comprehensive development report including optimized process conditions, kinetic and mass transfer data, safety assessment, and analytical methods. A technology transfer package is prepared to facilitate seamless scale-up at a CMO or internal facility.
