| Research Abstract |
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

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. Less
