Study on generation of new crystal substances and design of crystallizer, crystallizing operation under high utilization of resource, less consumption of energy and out of pollution

工业结晶是将固体从液相中沉淀为晶体的操作，并通过利用相变产生（或吸收）的能量、所获得的晶体和/或晶体分离后剩余液体的性质来评价。近年来的技术发展趋势是与资源的高利用率、低能耗和无环境污染相协调，在化学工业中，希望开发低成本的新功能物质的生产技术。晶体具有高性能、稳定的纯固体的特点，适合于生产这些物质的工业结晶对建立21世纪化学工业新技术的贡献进行了讨论。在此背景下，本研究小组决定研究什么是对21世纪化学工业发展有贡献的工业结晶。 ...更多信息 当然，工业结晶的新发展需要什么样的研究项目，目前工业结晶的技术和研究情况如何，报告是根据会员和规划项目获得和调查的研究结果，通过六个小组按基本原理，新课题，结晶器的设计和控制以及操作进行分类。然后总结了以下结论：结晶器的设计理论和操作的化工商品的生产提出了所需的产品的大小和数量，并满意地应用于工业目的。介绍了利用多晶相转变生产高纯度、新功能晶体和控制操作过饱和度的结晶新技术，认为工业结晶是发展化工的有效技术，对化工、医药、食品等工业的发展，特别是对污染防治有很大的贡献。少

Industrial crystallization is an operation of precipitation of solid from liquid phase as crystal and evaluated by utilization of energy generated (or absorbed) by transformation of phase, properties of obtained crystal and/or remained liquid after separation of crystal. The recent trend of development of technology is expected to be done in harmony with the circumstances of high utilization of resource, less consumption of energy and out of environmental pollution, and in chemical industry, development of production technology of new faculty substances is hoped under low cost. Crystal is characterized by pure solid of stable property for high faculty and industrial crystallization suitable to production of these substances was discussed on contribution to establishment of new technologies in a chemical industry in 21 century.On these back grounds, this study team decided to investigate what is an industrial crystallization contributed for development of the chemical industry in 21 cen … More tury, what research projects are required for new development on industrial crystallization, how about are the present technology and research on industrial crystallization, and the report was made from research results obtained and surveyed by members and from the planning projects, through six subgroups classified by fundamentals, new topics, design and control of crystallizers and operations. Then the following conclusions were summarized : Design theories of crystallizers and operations for production of a chemical commodity are proposed for desired size and amount of a product and applied satisfactorily for industrial purposes. And new crystallizing technology for production of high purity and new faculty crystal and for control of operating supersaturation by utilization of transformation of polymorphology are introduced.From these investigations, industrial crystallization is regarded as a effective technology for development of chemical industries, and largely contributes to development of chemical, pharmaceutical, food and other industries especially to prevention of pollution.
