精细化学品这个名词,沿用已久,原指产量小、纯度高、价格贵的化工产品,如医药、染料、涂料等。但是,这个含义还没有充分揭示精细化学品的本质。近年来,各国专家对精细化学品的定义有了一些新的见解,欧美一些国家把产量小、按不同化学结构进行生产和销售的化学物质,称为精细化学品(fine chemicals);把产量小、经过加工配制、具有专门功能或最终使用性能的产品,称为专用化学品(specialty chemicals)。中国、日本等则把这两类产品统称为精细化学品。 相似文献

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。 相似文献

Chemical Apparatus Engineering at a Turning Point? The ACHEMA conference is the leading international exhibition on chemical‐apparatus engineering, closely connected with the epochal developments of chemical and process engineering. At the moment it is most timely to think about new opportunities of development. Large‐scale plant engineering and general plant construction has experienced considerable improvement over the past decades, and the effects of these changes are particularly perceptible in the economic sector of German apparatus engineering. Economic pressures have given an additional impetus to a considerable shrinking process. Chemical apparatus engineering will have to focus on two main pillars in the near future: highly qualified standard and innovative products. Especially the latter must be developed in close interaction with chemical engineering in order to put the hardware required for new technologies and process strategies on the market. This article names the important fields of current general technical progress, showing that the main thrust is directed toward an elevated level of product quality that can be achieved through apparatus engineering. Such superior product properties are one important means to achieve higher profitability. 相似文献

The paradigms of chemical engineering discipline are discussed. The first paradigm of Unit Operations and the second paradigm of Transport Phenomena are well recognized among the chemical engineers all over the world, and what the next paradigm is remains still an open question. Several proposals such as Chemical product engineering, Sustainable chemical engineering and Multi-scale methodology are considered as candidates for next paradigm. Might Computational Chemical Engineering be the next one, which is advancing the discipline of chemical engineering toward ultimate mechanism-based understanding of chemical processes? This possibility is comparatively expounded with other proposals, and the scope and depth of computational chemical engineering are shortly listed. 相似文献
