Real- Time Monitoring andd Process Analytical Technology (PAT)

CSTR are e increate increate continuingly used in serie with plug- flow reactors (PFRS) to create corrigend continuous producturing lines. This configuation allows precise control of residence time distribution, improwing yield andd selectivity. Many commerces are transitioning from batch to continuous processes because operation inherently reduces reactor volume, solvent inventory, and energy neeeded for heating / cooling cycles.

For example, continuous producturing of activee appeeutical contexents (API) using a CSTR-PFR train has been shown to reduce total waste by up to 70% compared to batch syntetis.
