Introduction Esterification and hydrolysis are cornerstone reactions in the chemical and specialty esters industries. Traditionally, these reactions require multi-step batch processes first carrying out the reaction, then separating the products using energy-intensive distillation. This not only increases operational complexity and waste but also limits product purity and selectivity. Sulzer’s reactive distillation technology, however, redefines industry standards by combinin

Introduction: a new era of chemical engineering Process intensification is reshaping the chemical process industry driven by climate goals, space constraints, cost pressures, and the mounting demand for higher product quality. One of the most effective tools in this revolution is reactive distillation: a technology that elegantly unites chemical reactions and high-efficiency separation in a single step. Sulzer, a leader in mass transfer and separation technologies, is pioneer
