化学产品工程再认识

A revisit of chemical product engineering

化学产品工程作为化学工程学科的一个新方向或化学工程学科的新范式已提出很多年,但学术界对其学科内涵理解不一。本文对化学产品工程的学科内涵进行了分析和探讨,认为其核心是通过过程和设备对产品的纳微结构和复杂大分子结构进行调控;化学产品工程仍隶属过程工程,是面向高附加值产品、实现产品结构可控、定向、高效制备的过程工程。通过与传统的以满足市场需求和提高生产效率为目标的过程开发和放大的化学工程研究类比,提出了化学产品工程的主要研究内容,并讨论了其研究的方法论问题,以推动相关的基础研究工作。

Chemical product engineering(CPdE)as a new direction of research and education,or a new paradigm of chemical engineering(ChE)has been proposed for twenty years.However,interpretation of the core of the CPdE discipline is diverse and chemical engineers working for process development and scale-up feel confused and lost about their role in CPdE.In this perspective,the CPdE discipline is revisited and analyzed and the core of the discipline is proposed as the manipulation of the microstructure of products through chemical processes and achieved by using chemical equipments.CPdE still falls into chemical process engineering,which is the process engineering for controllable,targeted,and efficient fabrication of the structure of high value-added products.By analogy with process development and scale-up to meet market demand and to increase production efficiency,the research needs are identified for CPdE to control the microstructure and optimize the performance of products.Finally,the methodologies for CPdE are briefly discussed.
