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

工业结晶是指以晶体的形式从液体中析出固体的过程，并通过利用相转变产生(或吸收)的能量、得到的晶体的性质和/或结晶分离后的残留液体来进行评价。目前的技术发展趋势是与资源利用率高、能源消耗少、环境污染小的环境相协调的，在化学工业方面，希望在低成本下开发新的教员物质生产技术。晶体是一种性能稳定的高性能纯固体，适合于生产这些物质的工业结晶在21世纪对化学工业新技术的建立做出了贡献。在此背景下，本课题组决定研究什么是对21世纪化学工业发展做出贡献的工业结晶。…更重要的是，工业结晶的新发展需要哪些研究项目，目前工业结晶的技术和研究情况如何，报告是根据成员和规划项目获得和调查的研究成果，按基础、新课题、结晶器设计和控制和操作等六个子组进行分类的。总结出以下结论：提出了满足产品尺寸和用量要求的结晶器设计理论和化工产品生产操作，并成功地应用于工业生产。介绍了利用晶型变化控制操作过饱和度、生产高纯度新型晶体的新结晶技术，认为工业结晶是发展化学工业的有效技术，对化工、医药、食品等行业的发展，特别是对污染的防治有很大贡献。较少

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.
