Stirred‐Cell Minireactor with Modular Setup for Liquid‐Liquid Reactions

Abstract Modularization of chemical plants has gained recently importance due to its flexibility and shorter time‐to‐market. This is explored for stirred‐tank reactors (STRs) in the ENPRO initiative REUNION. A modular DN15 extraction cell, used as a highly automated continuous STR (CSTR), represents a reactor cascade and utilizes saponification reactions for performance assessment. Depending on the reactant ratio, the reaction occurs as a single‐phase (second‐order) or two‐phase (first‐order) process. The service design of modules is outlined and compared for different intentions and their application.
