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.
