Some experimental installations applied in the separation integrated technology were designed. The experimental installations included saponification and extraction installation, cryogenic centrifugation crystallization installation and continuous midium pressure column chromatography separation installation In the paper, a separation integrated technology route was designed： saponification and extraction-crystallization - silica gel column chromatography-recrystallization. Finally, refined solanesol （-95.5%） was successfully got. The new method featured shorter experimental times, as well as lower solvent consumption, compared with the conventional extraction methods. So it showed great potential for efficient sample preparation and large-scale industrial application in the near future.展开更多

The system setup workflow models which conform to the existing system and resource and the system adopts flexible workflow process mechanism to enhance the adaptability and opening and solve the exception and abnormality manipulation. The results show that it can not only provide the better dyeing order process, but also set dyer free from the fussy daily business and predigest task flow and heighten production efficiency.展开更多

As the core unit in coal chemical industry, ASU will greatly impact the engineering construction and operation/production of coal chemical business. In this paper, major suppliers of ASU at home and abroad were reviewed, and the major supplying status of ASU in China was introduced. The ASUs in operation of SINOPEC were listed and discussed. On this basis, some suggestions of ASU selection strategies were provided on localization, standardization and operation methods.展开更多
