업계의 과제 – 기존 공정이 비싸고 비효율적인 이유 수십 년 동안 화학 제품 생산은 “먼저 반응, 그다음 분리”라는 순차적인 방식을 따르고 있습니다. 반응기에서 전환 반응이 완료되고, 증류탑에서 정제 과정이 이루어집니다. 그 결과 공정이 길어지고…

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…
