How To Overcome Process Scale-Up Challenges Using Process Analytical Technology (PAT)

Process Analytical Technology for Scale-up

Process Analytical Technology

During Part I of his two part The Role of Process Analytical Technology (PAT) in Green Chemistry and Green Engineering online seminar series, Dominique Hebrault discussed scale-up challenges faced today by chemists and engineers.  Too often, offline sampling methods – mostly chromatographic methods such as High Performance Liquid Chromatography (HPLC) or Gas Chromatography (GC) – are used to monitor processes which fail to resolve common issues like reaction monitoring, poor mass balance, delayed initiation/reaction stalled, and loss of yield/by-products.  From a reaction engineering standpoint, obtaining heat mass balance information and preliminary kinetic data can be difficult using traditional offline methods during process scale-up.  Forming the final solid can be challenging using traditional offline methods, including filtration/drying a bottleneck, excessive washing, polymorph inconsistency, and batch to batch variability can be difficult.

Why is Kinetic Data Valuable?

Arguably, kinetics is one of the least popular subjects in academic or industrial research.  During her recent webinar – Reaction Progress Kinetic Analysis: A Powerful Methodology for Streamlining the Study of Complex Organic Reactions, Donna Blackmond reiterated why having kinetic data can be valuable:
