The construction content of this project includes an annual output of 2 × 400,000 tons (55%wt) formaldehyde plant, 2 × 300,000 tons of BDO plant, 2 × 120,000 tons of PTMEG plant and corresponding supporting facilities, etc. The total investment of the project is 1.3 trillion yuan. Phase 1 covers an area of ​​390,000 m2, while Phase 1.2 covers an area of ​​230,000 m2, totaling 620,000 m2.

On June 17, 2022, Inner Mongolia Junzheng Chemical Co., Ltd. 2×600,000 tons of BDO and 2×1,000,000 tons of PBAT/PBS/PBT and PTMEG green environmental protection recycling industry projects related to the first phase of the environmental impact assessment work. Second announcement.

The first phase of the project will build 600,000 tons/year of BDO (1,4-butanediol), 1 million tons/year of PBAT/PBS/PBT (polyadipic acid/butylene terephthalate/polybutylene succinate) glycol ester/polybutylene terephthalate), 80,000 tons/year PTMEG (polytetramethylene ether glycol) and supporting auxiliary facilities.

Junzheng Group stated on the investor interaction platform on June 15 that in May 2021, the company’s board of directors will invest in the company’s wholly-owned subsidiary to invest in the first phase of the green degradable plastic recycling industry project in combination with the national industrial policy and the company’s strategic development goals. After deliberation, it was agreed that the company’s wholly-owned subsidiary would invest in the construction of the first-phase project of the green and environmentally friendly degradable plastic recycling industry, which was approved by the 2020 annual general meeting of shareholders. At present, the project has obtained the review opinions of the National Development and Reform Commission’s filing documents and energy-saving reports.

The first phase of the project will build a PBAT/PBS/PBT/PTMEG co-production plant with an annual output of 1 million tons, a BDO plant with an annual output of 600,000 tons, a carbon-based material hydrogen production plant, and an annual output of 800,000 tons of formaldehyde synthesis (55%wt) The total investment of the project is expected to be 20.7 billion yuan, which will be invested successively with the project construction.

Through the deep coupling of the above coal coking chemical industry and chlor-alkali chemical industry, the maximum utilization of resources and energy can be realized, the development goal of “extending the chain, supplementing the chain, and strengthening the chain” can be realized, and the green coupling and upgrading of the coking industry and the degradable plastics industry can be realized. , which helps to ensure the long-term competitiveness of the project.

Invista’s technology license is adopted for the BDO project of Invista Group. Previously, Chengda Company has cooperated with Invista Company to successfully complete the construction of more than 20 sets of BDO units in China, and the total production capacity accounts for more than 80% of the existing domestic production capacity. The BDO project with a single-line annual output of 300,000 tons that the two parties have joined hands with this time will greatly increase the global record of BDO’s single-line production capacity. effect.
