In the field of API and intermediate production, Continuous Flow Manufacturing (CFM) is revolutionizing traditional production models with its disruptive advantages.
This technology utilizes equipment such as microreactors and continuous stirred tank reactors to transform batch production into dynamic continuous processes, significantly enhancing efficiency and safety while serving as a critical stepping stone for the pharmaceutical industry’s transition toward intelligent manufacturing.
Continuous flow systems achieve millimeter-level reaction control by real-time monitoring of parameters such as temperature, pressure, and pH.
For example, in nitration reactions, traditional batch processes are prone to safety incidents due to heat accumulation, while microchannel reactors can reduce reaction time to seconds, improve heat diffusion efficiency by 90%, and maintain product purity above 99.5%.
Equipment footprint reduced by 70%: After renovation, the production capacity of a cephalosporin intermediate production line increased from 50 kg/day to 200 kg/day per unit.
Solvent consumption reduced by 40%: Continuous extraction processes replaced multi-stage liquid-liquid separation operations.
Labor costs reduced by 65%: Automated systems enable 24/7 unmanned operation.
Continuous flow processes enable VOC emissions to comply with EU REACH regulations. A certain anticancer drug intermediate production line achieves zero wastewater discharge through a closed-loop water circulation system.
