[Construction of the main unit’s civil works for Yizheng Chemical Fiber’s 3-million-ton-per-year PTA project officially begins] On July 22, at the construction site of Yizheng Chemical Fiber’s 3-million-ton-per-year PTA project, the civil works contractor began trial pile driving. With the driving of the first test pile, the civil works for the main unit officially commenced, marking the official start of project implementation. This is a significant milestone in the project’s development, signaling the beginning of the construction of the largest single-unit facility in terms of investment in Yizheng Chemical Fiber’s 43-year history. PTA is a raw material for polyester products, and high-quality PTA serves as an essential factor in enabling Yizheng Chemical Fibers to develop stronger, higher-quality products and expand its production of mid-to-high-end synthetic fibers and new materials. Yizheng Chemical Fibers’ project with an annual production capacity of 3 million tons of PTA is Sinopec’s first facility of this kind, capable of producing 3 million tons of PTA per year. It represents an important step for Sinopec in strengthening its aromatic chemicals industry chain, developing high-end new materials, and accelerating the establishment of an industrial structure based on \"one core, two wings, and three new areas\" ; It is the flagship project for Yizheng Chemical Fibre’s transformation and upgrading during the 14th Five-Year Plan period, as well as for its high-quality development; it has been included in the list of projects under the supervision of Sinopec’s board of directors and among Sinopec’s key projects ; This project meets Jiangsu Province’s requirements regarding the optimization, strengthening, and supplementation of industrial chains, and it has been included in Jiangsu Province’s list of major projects for 2021. Since the start of the project construction, Yizheng Chemical Fiber has made great efforts to uphold the excellent work ethic demonstrated in the development of the melt-blown fabric project, taking initiative, following a planned approach, and overcoming various challenges. On July 22nd, an important milestone was reached: the 3 million-ton PTA project officially entered the implementation phase. (Photo/Text by Liu Yufu and Zhai Ruilong)
From June 8 to 9, the Development Planning Department of Sinopec Group held a review meeting for the basic design of the 3 million tons per year PTA project at Yizheng Chemical Fibers. Participants in the meeting included the Group’s Materials and Equipment Department and Chemicals Business Unit, as well as the design firms Engineering Construction Co., Ltd. and Nanjing Engineering Company, Jiangsu Electric Power Design Institute. The project owner, Yizheng Chemical Fibers, and invited experts also attended the meeting. The meeting was chaired by Gao Mingyu, deputy manager of the Project Review Department in the Group Company’s Development Planning Department. Liu Jianjun, the company’s deputy general manager, along with staff from relevant departments, attended the entire review session. The foundation design review for Yizheng Chemical Fiber’s 3 million tons per year PTA project has been completed, marking another significant advancement in the project’s progress. The three design firms—Engineering Construction Company, Nanjing Engineering Company, and Jiangsu Electric Power Institute—presented their respective foundation design proposals.
Sinopec Yizheng Chemical Fibers’ new PTA plant with an annual capacity of 3 million tons utilizes Inovance technology. Oil and chemical supply industry news: On January 21, according to Inovance’s official WeChat account, the company signed a technical agreement with Sinopec International Business Company, granting Yizheng Chemical Fibers the right to use Inovance’s latest P8++ technology to build a new production line – this will be Yizheng Chemical Fibers’ third PTA production line. The facility is located in Jiangsu Province, with a designed production capacity of 3 million tons per year. Yizheng Chemical Fibers had previously used Invista’s PTA P6 technology to build its second production facility, with a designed annual capacity of 450,000 tons. Yizheng Chemical Fiber and Invista are very pleased to work together again to create long-term value for both parties. At the recent project kickoff meeting, Mr. Guo Xiaojun, General Manager of Yizheng Chemical Fibers, expressed his confidence in Invista’s PTA technology and his gratitude to the technical team: “The 3 million-ton-per-year PTA project is a key development project under Sinopec’s 14th Five-Year Plan, and it is also considered the ‘lifeline’ project for Yizheng Chemical Fibers.” I look forward to the full cooperation between both parties to efficiently advance the project construction with the goals of \"high quality, rapid progress, and cost savings,\" and to ensure its successful implementation. ”
Starting from December 30, 2020, Sinopec Yizheng Chemical Fiber Company began carrying out the demolition work of 5 unused crude oil storage tanks and related facilities in the chemical tank farm of the PTA department, in order to prepare for the construction of the storage, transportation, and wastewater treatment renovation projects in that department. In 2021, the company will proceed as planned with the construction of a new PTA plant with an annual capacity of 3 million tons. To make room for this project, 5 old storage tanks will be demolished, and 5 new tanks for acetic acid, alkalis, and azeotropes will be built in their place, so as to ensure the safe and stable operation of the PTA plant’s first and second production lines. To ensure the timely commencement of the relocation project, it is necessary to complete the removal of the old tanks and site grading as soon as possible. To this end, the company’s project construction management department strictly adheres to the relevant requirements regarding the safe storage of hazardous chemicals and environmental protection, formulates a scientific plan for the demolition of the storage tanks, and accelerates the demolition process while ensuring the safe production in the tank area.
This demolition operation abandons traditional methods such as manual construction of scaffolding and welding, cutting, and heating processes; instead, it employs a new mechanical demolition approach that involves no use of fire, welding, or scaffolding. This reduces labor costs and the number of people present in the work area, thereby ensuring the safety of the construction process. . Additionally, traditional manual cutting takes nearly a month, whereas mechanical removal allows an entire tank to be taken down in just 4 hours, **saving time and ensuring that subsequent relocation projects can be carried out on schedule.
In what ways is this P8++ technology more advanced than P8?
Production capacity has increased; the capacity for P8 is 200–250 WT, while that for P8++ is 300 WT. There should be no significant changes in the manufacturing process
