The 100 tons/hour solids air flow test device developed by Shanghai Jinshende Powder Engineering Co., Ltd. and Shanghai Engineering Co., Ltd., and the large-scale powder PTA conveying engineering technology research and application technology development project, have recently passed the Sinopec Joint Stock Company. Technical appraisal organized by the Ministry of Science and Technology. The expert group believes that the research and development work of the project has met the technical requirements specified in the contract. After the industrial application assessment, the test device and technology have reached the international advanced level.
The engineering research of China's air-flow transportation specialist started late, and the scale of the research device is relatively small. This has led to a long-term dependence on imports for the domestic petrochemical enterprises' air-conveying technology. To this end, in 2003, the Science and Technology Development Department of Sinopec Corp. hired a German expert for technical guidance to build Sinopec's large-scale pneumatic conveying experimental device for powder pellets, and set up a professional research and engineering application company for airflow conveying. Shanghai Jinshende Powder Engineering Co., Ltd. , Started the engineering research on the solid material flow transportation test in the petrochemical industry to realize the localization of the large-scale pneumatic conveying technology of powder pellets.
During the three years, the project team completed the experimental research and data processing of PTA, PET, polypropylene, polyethylene, etc. The test device was completed and put into operation in July 2005. Has filed three patents and authorized two. At present, the technology has been successfully applied to the Shanghai Petrochemical PTA reconstruction project, and has provided technological transformation programs for the problems existing in the gas flow production equipment such as Zhongyuan Polypropylene, Qilu Petrochemical PVC, Yizheng Chemical Fiber PTA and so on.
Director of the appraisal committee, chief engineer of China Petrochemical Corporation and academician of the Chinese Academy of Engineering Cao Xianghong pointed out that the development and successful application of the solid material air flow transmission technology has taken an important step for the localization of Sinopec's polyolefin complete sets of technology, after turning back large domestic ethylene plants. The long-term dependence on the status quo of foreign countries is of great significance for the processing of solid material flow conveying technology.
