The total investment is 33 billion yuan! This new material project has started trial production with feedstock input
At 11:38 a.m. on December 2nd, in the control room of Sichuan Yongying New Materials Co., Ltd. in the Chemical Industrial Park of Nanchong Economic Development Zone, with the order given by the production dispatching manager, the central control operator carried out the ignition operation as instructed. The natural gas valve was opened, and the automatic ignition equipment was activated. Slowly, the flame of the safety torch and the eternal light rose.
Under the joint witness of over 100 leaders and guests including the Sichuan Provincial Committee and Provincial Government, the Nanchong Municipal Committee and Municipal Government, financial institutions, industry associations, and customer representatives, the trial production ceremony of the first phase A line of the Sichuan Yongying 800,000-ton annual functional new materials integrated industrial chain Project, invested by Yongrong Holding Group, was successfully held. At the ceremony, natural gas was introduced to the production facility area of the project, and the safety torch of the acetylene cracking unit was successfully ignited. All the trial production work will be carried out in an orderly manner, marking the completion of the A line construction of the first phase of the project and the official entry into the trial production stage of feeding materials.
At present, the fuel gas pipeline network of the entire plant has been put into operation. The tail gas waste heat recovery and utilization device and the organic tar recovery and utilization device have been ignited, heated up and pressurized. The main device has entered the heat combined operation mode. The acetylene cracking unit has begun to be ignited for furnace drying and trial furnace operation. Next, the trial production work will be safely launched as planned, and the processes of each main unit will be unblocked. From acetylene, hydrogen, formaldehyde, BYD to the production of qualified BDO, step by step, under the principles of safety, greenness and efficiency, the designed quality indicators and production capacity will be gradually achieved.
It is understood that the Sichuan Yongying New Materials Project is the largest single project in terms of investment scale in the industrial field of Nanchong. The successful commissioning of this project will convert natural gas into high-value-added chemical products, providing basic chemical raw materials for the market in the southwest region, promoting the integration of downstream enterprises within the Economic Development Zone Chemical Park, facilitating the industrial development and upgrading of the entire park, increasing local tax revenue, and effectively promoting the economic development of the Nanchong area.
Project Details
The Yongying New Materials 800,000-ton functional new materials integrated industrial chain project has a total investment of approximately 33 billion yuan and covers an area of about 5,000 mu.
In June 2022, the draft of the environmental impact report for the first phase of the 800,000-ton functional new materials integrated industrial chain project of Sichuan Yongying New Materials Co., Ltd. was released for public display. The environmental impact report shows that Yongrong Group plans to produce BDO using natural gas as raw material and the acetylene-aldehyde method technology, and extend to the downstream industrial chain to implement the "800,000-ton functional new Materials integrated industrial Chain Project".
The project is planned once and implemented in phases. The first phase of the project includes the construction of an acetylene plant from natural gas, a formaldehyde plant, a 1, 4-butanediol (BDO) plant, a polybutylene adipate/terephthalate (PBAT) plant and a polytetrahydrofuran (PTMEG) plant, as well as the supporting public utilities and auxiliary production facilities. Form a production scale of 300,000 tons/year BDO, 60,000 tons/year PBAT and 60,000 tons/year PTMEG. The second phase has a production capacity of 300,000 tons per year for BDO. The third phase of the project will use the BDO produced in the first and second phases as raw materials and extend downstream to build the remaining PBAT unit, PTMEG unit and spandex unit.
