Yizheng Chemical Fiber: Projects with an annual output of 120,000 tons of PBT/60,000 tons of biodegradable materials started

Latest News: Recently, Sinopec Yizheng Chemical Fiber held the launching ceremony of the new generation bottle flake transformation project with an annual output of 500,000 tons and the flexible transformation project with an annual output of 120,000 tons of PBT/60,000 tons of biodegradable materials. This marks an important measure for Yizheng Chemical Fiber Company to strengthen and expand Sinopec’s PBT industry chain, and to refine and optimize biodegradable products. The project has entered the stage of comprehensive construction.

Yizheng Chemical Fiber’s new-generation bottle flake transformation project with an annual output of 500,000 tons and a flexible transformation project with an annual output of 120,000 tons of PBT/60,000 tons of PBXT are the “leading projects” for the transformation and upgrading of Yizheng Chemical Fiber during the “14th Five-Year Plan” – with an annual output of 300 The polyester and new material projects supporting the 10,000-ton PTA project are of great significance to accelerating the high-quality development of Yizheng Chemical Fiber and enhancing the competitiveness of the industrial chain.

500,000 tons/year new generation bottle flake transformation project

At present, Yizheng Chemical Fiber is accelerating the construction of a PTA project with an annual output of 3 million tons. The project is planned to be completed and put into operation in the first half of 2023. After the completion of the PTA project with an annual output of 3 million tons, the existing PTA units 1 and 2 will be shut down.
The annual surplus is about 850,000 tons. Therefore, it is planned to build a series of PTA downstream product projects with an annual output of 400,000 tons of staple fiber, an annual output of 500,000 tons of bottle flakes, and an annual output of 240,000 tons of flexible PBT, giving full play to the advantages of PTA raw materials and base scale to improve PXPTA-PET industry chain, enhance the company’s overall market competitiveness.

Bottle flakes are the traditional advantageous business of Yizheng Chemical Fiber. According to the development of the market, moderately speed up the production capacity layout, which is conducive to coping with the competition of private enterprises and consolidating the dominant position in the market. Therefore, the company plans to further expand the production capacity of bottle flakes, and invest about 1.06 billion yuan to build a new generation bottle flake transformation project with an annual output of 500,000 tons in the boundary area of ​​the PTA department of the existing plant.

The main construction contents include: a set of 500,000 tons/year bottle flakes device and supporting heat medium station, intelligent three-dimensional warehouse, etc. After the project is put into operation, the existing fourteen polyester unit of the original four polyester factory (now the bottle flake department) is 200,000 yuan. ton/year bottle-grade polyester chipping device and polyester fifteen unit 200,000 tons/year film-grade polyester chipping device were discontinued.

The annual output of 120,000 tons of PBT/60,000 tons of PBXT flexible transformation project

Yizheng Chemical Fiber plans to invest about 380 million yuan to build a flexible transformation project with an annual output of 120,000 tons of PBT/60,000 tons of PBXT. The proposed construction site is located in the north area of ​​the former security inspection company of Yizheng Chemical Fiber Company. After the project is completed, the annual output will be 120,000 tons of PBT/60,000 tons of PBXT.

Existing projects and their environmental protection:

Sinopec Group Asset Management Co., Ltd. Yizheng Branch currently has 3 production lines:

Line B01 is a 20,000-ton/year PBT unit (including a 1,300-ton/year by-product tetrahydrofuran rectification unit); B02 line is a 60,000-ton/year PBT unit (including a 3,660-ton/year by-product tetrahydrofuran rectification unit); B03 line is 6 10,000 tons/year PBT unit (including 5,072 tons/year by-product tetrahydrofuran rectification unit).

At present, the three production lines are running normally.
