精细化工与高新分离技术

Fine Chemicals and High and New Separation Technology

随着近几年新兴精细化工行业不断出现和对精细化工产品纯度要求越来越高的发展趋势,运用高新分离技术成为促进我国精细化工行业发展的关键。本文介绍了三项高新分离技术:分子蒸馏技术、超临界萃取技术及高效离心传质技术。通过与传统分离方法的对比和应用实例说明了新技术的优点。

With the emerging of nearly-risen fine chemicals and increasingly higher requirements for product purity of fine chemicals in these years, the adoption of high and new separation technology has become the key of promoting the development of fine chemicals in China. Three high and new separation technologies are introduced in this article: molecular distillation technology, supercritical extraction technology, high efficiency centrifugal mass transfer technology. This article also discribes the advantage of the new technology through comparison with traditional separation methods and application examples.
