In lab-scale trials of melt crystallization, our primary objective is not achieving peak purity initially, but rather determining the technical viability of the material for further process development. When clients inquire whether a specific substance can be purified via melt…

Industry Challenge – Why Conventional Processes Are Expensive and Inefficient For decades, chemical production has followed a sequential “reaction first, separation later” configuration. Reactors complete conversion, while distillation columns handle purification. The result is a long process route with high…

Preface: Why “Catalyst Packing” Becomes the Make-or-Break Factor for Reactive Distillation Reactive distillation (RD) and catalytic distillation (CD) are representative process intensification technologies that synergistically integrate reaction and separation within a single column. On one hand, timely removal of products/by-products…

In typical reactions such as etherification, esterification, and hydrogenation, traditional processes usually face three common bottlenecks: (1) Due to balance constraints, the conversion rate cannot be further increased; (2) Strong heat release leads to hotspots and side reactions; (3) The…

Surging Demand for High-Purity Chemicals Is Pushing Conventional Separation Technologies to Their Limits Chemical separation is often described as the “invisible heart” of the chemical industry. A less recognized fact is that separation processes account for approximately 40%–70% of the…

An Invisible Problem Inside Everyday Plastics The plastic baby bottle used for infant formula, the cling film wrapped around a sandwich, and even the interior trim responsible for the “new car smell” may all contain trace amounts of unreacted raw…

A Counterintuitive Fact — A Pipe Can Also Be a Reactor Imagine two cooking methods. One uses a large pot where all ingredients are added together and mixed slowly with a stirring spoon, while temperature control depends heavily on operator…
