Thread Content

Inner Mongolia Jiutai Xinyuan New Materials Co., Ltd. is the construction unit of the carbon dioxide/synthesis gas to aromatics industrial pilot project: Inner Mongolia Jiutai Xinyuan New Materials Co., Ltd. ； construction nature: New ； construction site: Dalu Industrial Park, Zhungar Banner, Ordos City, Inner Mongolia Autonomous Region ； Total investment and environmental protection investment: The total investment of this project is 136.51 million yuan, of which environmental protection investment is 9.555 million yuan, accounting for 7.0% of the total investment. ； Covered area: The total area of ​​the project is approximately 32.25hm2, and the actual land area is 5.98hm2 ； Construction period: 2021-2022 ； The production scale project adopts the carbon dioxide/synthesis gas-to-aromatics process developed by Tsinghua University. The production scale is 9722.8656 tons/year of 1,2,4,5-tetramethylbenzene and 12755.52 tons/year (49.4542 million Nm3/a) of crude hydrogen. The project is divided into two production working conditions, of which working condition 1: The raw gases are carbon dioxide and synthesis gas, and the working hours are 1440h (60 days) ； Working condition two: The raw material gas is synthesis gas, and the working hours are 7200h (300 days). Project Product Plan The main product is 1,2,4,5-tetramethylbenzene 9722.8656t/a, and the by-product crude hydrogen is 12755.52 tons/year (49.4542 million Nm3/a) Construction content: Inner Mongolia Jiutai Xinyuan New Materials Co., Ltd. has invested in a new carbon dioxide/syngas to aromatics project in the Coal Chemical Industrial Park of Dalu New District, Jungar Banner, Inner Mongolia, with a production scale of 9722.8656 tons/year of 1,2,4,5-tetramethylbenzene and 1 2755.52 tons/year (49.4542 million Nm3/a) crude hydrogen, 8640 hours of annual operation, 70 employees in the plant, and a total investment of 136.51 million yuan, of which 9.555 million yuan is environmental protection investment, accounting for 7.0% of the total investment. The project consists of main engineering, public engineering, storage and transportation engineering, auxiliary engineering, environmental protection engineering and supporting engineering. Main project: The project includes working condition one (carbon dioxide and syngas feeding) and working condition two (syngas feeding). This project is a test project. The working condition one runs for 1440h and the working condition two runs for 7200h. After the test reaches the expectation, it will be re-approved and transferred to industrial production. Each working condition includes five working sections: raw gas pretreatment section, reaction section, quenching and circulating gas compression section, aromatic hydrocarbon distillation section, and crystallization separation section. The raw gas pretreatment section of the two working conditions each uses a set of process equipment. The four sections of the reaction section, quenching and circulating gas compression section, aromatic hydrocarbon distillation section, and crystallization separation section share a set of process equipment. Public works: Water supply and drainage (including circulating water system, desalted water station, deaeration system), steam, gas supply, power supply, etc. Storage and transportation engineering: Pipe corridors, hazardous chemical warehouses, finished product warehouses, hazardous waste temporary storage warehouses, atmospheric tank areas (including C6~C9 storage tanks, light removal tower feed tanks, heavy weight removal tower feed tanks, all intermediate tanks), etc. Auxiliary works: Laboratory, control room and substation, etc.
