At 11:38 a.m. on December 2, in the control room of Sichuan Yongying New Materials Co., Ltd. located in the Nanchong Economic Development Chemical Industrial Park, upon the command of the production scheduling manager, the control room operators carried out the ignition procedure as instructed. The natural gas valves were opened, the automatic ignition equipment was activated, and gradually, the flame of the safety flare began to burn steadily. The commissioning and trial production ceremony for Line A of Phase 1 of the Sichuan Yongying project, an integrated industrial chain for producing 800,000 tons per year of functional new materials, invested by Yongrong Holding Group, was successfully held. During the ceremony, natural gas was introduced to the project’s production facility area, and the safety torch for the acetylene cracking unit was successfully ignited. Various tasks related to trial production will be carried out in an orderly manner, marking the completion of the construction of Line A of the project’s first phase and the official entry into the stage of trial production with material feeding. At present, the fuel gas network across the entire plant has been put into operation. The exhaust heat recovery system and the organic tar recovery system have been started up to increase temperature and pressure, and the main unit is now in thermal integration mode. The acetylene cracking unit has begun the process of heating up and testing. Next, the pilot production will be launched safely as planned, with the processes of various main units connected together. Starting from acetylene, hydrogen, formaldehyde, and BYD, qualified BDO will be produced step by step, and in line with the principles of safety, sustainability, and efficiency, the designed quality standards and production capacity will be gradually achieved. It is understood that the Sichuan Yongying New Materials project is the largest single investment project in Nanchong’s industrial sector. The successful commissioning of this project enables the conversion of natural gas into chemicals with high added value, providing essential chemical raw materials for the market in the southwestern region. It facilitates the integration of downstream enterprises within the Economic Development Chemical Park, promotes the upgrading of the industries in the entire park, increases local tax revenues, and thus contributes effectively to the economic development of the Nanchong area. The 800,000-ton integrated industrial chain project for functional new materials involves a total investment of 33 billion yuan. It is located in the Hexi Chemical Park of Nanchong Economic Development Zone, and the natural gas acrolein method is used in its production. The project aims to produce 600,000 tons per year of BDO, 500,000 tons per year of PBAT, and 300,000 tons per year of spandex. It will be implemented in three phases: Phase 1 will involve the production of 300,000 tons per year of BDO, 60,000 tons per year of PBAT, and 60,000 tons per year of PTMEG ； Phase 2: 300,000 tons/year BDO production capacity ； Phase 3: Using the BDO produced in Phases 1 and 2 as raw material, the project will expand downstream to build the remaining PBAT plants, PTMEG plants, and spandex plants. One phase of this project is constructed in two lines, A and B: Line A includes a facility for producing acetylene from natural gas at a capacity of 50,000 tons per year, a facility for producing formaldehyde from acetylene waste gas at a capacity of 2×240,000 tons per year, as well as a BDO production plant with an annual capacity of 150,000 tons. In addition, there are supporting utilities, environmental protection systems, as well as service facilities such as a production control center, a cultural center, a management center, and a innovation center ； Line B includes 50,000 tons per year of acetylene produced from natural gas, 240,000 tons per year of formaldehyde produced from acetylene off-gases, a BDO plant with an output of 150,000 tons per year, a PBAT plant with an output of 60,000 tons per year, and a PTMEG plant with an output of 60,000 tons per year, along with the associated utility and environmental protection facilities.
