Professor Qiu Ruchen is now working at HaiChuan. 【We currently handle design and calculation tasks as well as process package design work.】 If you have any needs, please contact the \"HaiChuan Online WeChat customer service\". Key achievements: Professor Qiu Ruchen from Qingdao University of Science and Technology has officially retired. The main achievements of the 33 process packages that have been developed and implemented are as follows: First, process packages available for technology transfer. 1. In collaboration with Professor Li Jianlong, a process package for the \"rapid biomass pyrolysis system\" was developed (the first of its kind in the country) ； The SHZ-980 biomass rapid pyrolysis device was listed under the **Torch Program** by the Ministry of Science and Technology in 2007. The scale of the biomass pyrolysis demonstration unit operated by Jilin Yiminbao New Energy Development Co., Ltd. has reached 1,000 Kg/h of material. Issue 473 of the Science and Technology Daily, in its front-page headline in the “Innovation Weekly” section, reported on this facility. The design and development of a biomass thermal pyrolysis unit with a capacity of 3000 Kg/h have been completed. 2. Developed offshore drilling oil sand dewaxing technology in collaboration with Professor Li Jianlong (performance indicators are world-leading; it represents the first such process flow in the world) ； 3. Developed a 10,000-ton-per-year continuous production technology for thionyl chloride in collaboration with Professor Li Jianlong (the first of its kind in the country, and successfully put into operation) ； 4. Developed a complete set of process technologies for organic silicon production with a capacity of 200,000 tons per year, in collaboration with Professor Li Jianlong. 5. Developed a concentrated acid hydrolysis process for dimethyl monomers used in organic silicon production, also in collaboration with Professor Li Jianlong; this was the first such process of its kind in China, as foreign countries imposed a technology blockade on China in this area. Three such systems have been built in China to date. 6. In collaboration with Professor Li Jianlong, a new distillation process for dimethyl monomers in silicone production was developed, resulting in >40% energy savings in distillation and a purity of the dimethyl product of >99.96% (wt). 7. Developed the diketene process in collaboration with Professor Li Jianlong. 8. Developed the vinyl acetate process in collaboration with Professor Li Jianlong. 9. In collaboration with Professor Li Jianlong, processes for the recovery of hydrogen chloride (electronic grade) and sulfur dioxide waste gases were developed (several such systems have been successfully developed and put into operation). Only process packages numbered 1 to 9 are available for transfer, and cooperation with Professor Li Jianlong’s research team is required. 10. In 2020, the recovery and purification of waste hydrogen fluoride at TSMC was completed (scheme design finished). 11. Catalyze dry gas recovery for compressed natural gas process (complete scheme design). 12. DMF waste gas recovery process (successful commissioning, significant economic benefits). Items 10 to 12 allow for the transfer of either the process package or the process calculation sheet. 13. Pharmaceutical-grade PG production and Class S DMC production processes at Shandong Shida Shenghua Chemical Group Co., Ltd. 14. Process for improving the quality of dimethyl carbonate production at Shida Shenghua Chemical Group Co., Ltd. in Shandong Province. 15. Development of a 40,000-ton/year EC process package by Shandong Shida Shenghua Chemical Group Co., Ltd. 16. Development of a 50,000 tons/year DMC production process package using the PC method by Shandong Shida Shenghua Chemical Group Co., Ltd. 17. Shandong Shida Shenghua Chemical Group Co., Ltd.’s 20,000 tons/year EC process. 18. The production process for 40,000 tons per year of EC using different raw materials at Shandong Shida Shenghua Chemical Group Co., Ltd. 19. Production process for 40,000 tons per year of PC using different raw materials at Shandong Sinopec Shenghua Chemical Group Co., Ltd. 20. The production process for different raw materials at Shandong Sinopec Shenghua Chemical Group Co., Ltd.: the DMC production process using the PC method with an annual capacity of 50,000 tons. 21. The production process for different raw materials at Shandong Shida Shenghua Chemical Group Co., Ltd.: a 50,000-ton/year DMC production process using the EC method. 22. Carbonate process optimization project of Shandong Shida Shenghua Chemical Group Co., Ltd. 23. Development of the technical package for the accelerator NS in the process technology package for Saint Oh Chemical’s Legend project. 24. Development of the technical package for the accelerator MDM in the process technology package for Saint Oh Chemical’s Legend project. 25. Design project for continuous distillation of 1,500 tons per year of ethyl chrysanthemic acid at Linyi Guangchen Chemical Co., Ltd. 26. Energy-saving and environmental-protection technology renovation project for the tertiary amine workshop (401) of Shandong Fuster Oil Co., Ltd. (including methamine and dimethamine recovery). Items 13 to 26: Due to a confidentiality agreement signed with the client, the process package will not be transferred, nor will any technologies be transferred, and the process calculation documents will not be sold. For display only as a development result. 27. Low-temperature super-efficient evaporation concentration process. 28. Integrated technology of enhanced evaporation concentration and crystallization. 29. Development of treatment processes for refractory organic wastewater. 30. Development of specialized distillation equipment and associated processes. 31. Technology for converting batch reaction processes to continuous reaction processes and equipment. 32. Water vapor recovery process for cooling towers and technologies for utilizing low-temperature waste heat. 33. Helium recovery process. Items 27 to 33 involve models such as process development on commission, collaborative development, equipment development, transfer of complete sets of equipment, and transfer of complete sets of technologies. We have a strong process development team with full capability to develop new processes. For advanced foreign process technologies, we can create process models for them (we have successfully developed and put into use multiple sets of process units whose use was restricted by foreign countries), and optimize the processes and equipment involved in order to break through such technical restrictions and improve economic efficiency. At the same time, specialized software can be developed to accurately establish process mathematical models based on actual operational data, thereby optimizing the processes and reducing energy consumption to meet the actual process requirements of manufacturing enterprises. Saves valuable process development funds, resources, and time for manufacturing enterprises. All the calculation documents are prepared for actual engineering design, using the production data of real enterprises as the basis for calculations; most of these calculations reach a level sufficient for detailed engineering design (except those marked as \"preliminary\" or \"conceptual study\”). It is firmly stated that all the process calculations were carried out by Professor Qiu Ruchen himself. Professor Qiu Ruchen holds all copyrights and rights to the calculation documents.
