On May 12, the environmental impact report of the 1,000-ton straw sugar to ethylene glycol pilot project of Henan Zhongyuan Dahua Group Co., Ltd. was announced before approval.
Henan Zhongyuan Dahua Group Co., Ltd. plans to actively participate in the design and development of biomass ethylene glycol pilot projects Development work, comprehensive mastery of biomass ethylene glycol process technology, accumulation of engineering experience, and laying a solid foundation for the company’s industrial amplification in this technology field. Against this background, the company plans to invest in the construction of a 1,000-ton straw sugar-to-ethylene glycol pilot project, relying on Zhongke Boyijin (Zhengzhou) New Energy Technology Co., Ltd. (Dalian Institute of Chemical Physics, Chinese Academy of Sciences and Henan Keyuan Industry Investment Fund Partnership) is the first new biomass-to-ethylene glycol route with independent intellectual property rights. It is jointly developed by Donghua Engineering Technology Co., Ltd., Zhongke Boyijin and Zhongyuan Dahua, and is designed for pilot scale-up.
After completion, the pilot project can produce 746.8t/a ethylene glycol and 194.4t/a propylene glycol annually. The main raw materials of the project are straw sugar aqueous solution and H2. Ethylene glycol is generated through ethylene glycol synthesis and ethylene glycol distillation reaction. Project H2 comes from the existing project of Zhongyuan Dahua Company. It does not require storage and is directly transported by pipeline.
On the morning of April 9, 2021, the opening ceremony of the Zhongyuan Dahua 1,000-ton straw sugar to ethylene glycol pilot project undertaken by the 11th Chemical Construction Ninth Engineering Company went smoothly. held. This project is a PC project, a design-and-construction project with a construction period of 184 days.
Project Overview
The project construction location is Puyang Economic, Technological and Industrial Cluster Area, Puyang City (including Puyang Economic Development Zone) Southwest corner of the intersection of Shihua Road and Pushui Road (within the existing factory area of Zhongyuan Dahua Company) Total investment: 20.98 million yuan, project code: 2020-410972-26-03-030443
The project mainly constructs a 1,000-ton ethylene glycol pilot plant. After completion, it can produce 746.8t/a of ethylene glycol and 194.4t/a of propylene glycol. This project uses biomass straw sugar aqueous solution and hydrogen as raw materials. It undergoes hydrogenation reaction in the ethylene glycol synthesis section to synthesize crude ethylene glycol, and then passes through the ethylene glycol distillation section to obtain high-quality ethylene glycol products. At the same time, the by-product industry grade propylene glycol, etc. The main construction equipment includes ethylene glycol synthesis, ethylene glycol distillation and other processes.
Henan Zhongyuan Dahua Group Co., Ltd. is located in Puyang Economic, Technological and Industrial Agglomeration Area and is divided into two factory areas: natural gas chemical equipment area and coal chemical equipment area. The construction site of this 1,000-ton straw sugar to ethylene glycol pilot project is located in the existing factory area of the coal chemical plant area. The public and auxiliary projects of the project rely on the existing facilities in the coal chemical plant area. Therefore, the existing projects in the coal chemical plant area are mainly affected. and its environmental protection measures are introduced.
The main projects in the coal chemical plant area include a 300,000-ton methanol project, a sewage treatment unit standard expansion and transformation project, and a 1,000-ton methyl methacrylate (MMA) synthesis pilot development project. Projects, coal-fired boiler flue gas desulfurization and dust removal integrated ultra-low emission transformation project, 300,000 tons/year liquid carbon dioxide recovery and utilization project (currently the first phase of 50,000 tons/year carbon dioxide recovery has been completed); among them, the sewage treatment device has been upgraded to expand its capacity The transformation project and the coal-fired boiler flue gas desulfurization and dust removal integrated ultra-low emission transformation project are the sewage treatment of the 300,000 tons/year methanol project and the environmental protection treatment project of the coal-fired boiler. </p
