The total investment is 13 billion yuan! Inner Mongolia Sanwei Phase I 300,000-ton BDO and 100,000-ton PBAT project trial operation

Sanwei Shares announced on the evening of November 21 that the main body of the BDO integrated project (Phase I) constructed by its holding subsidiary Inner Mongolia Sanwei New Materials Co., Ltd. has been completed and put into trial operation. The calcium carbide and BDO equipment have been The whole line is connected, and the products reach the level of high-quality products.

The project applies innovative processes and devices, has a high degree of automation and intelligence, and has significantly improved unit consumption, production efficiency, product quality and clean production. At the same time, it relies on Wuhai’s high-quality blue charcoal, limestone and other rich resources, combined with The company has its own raw material calcium carbide production capacity, self-provided generator sets and other cost reduction and carbon reduction projects, and has obvious market competitive advantages. The commissioning of this project marks the company’s formal entry into the new materials industry, which will help broaden revenue growth channels, improve profitability, enhance risk resistance, and push the company’s development to a new level.

Sanwei shares stated that the above-mentioned projects will take some time from trial operation to full production, and may also face the impact of uncertain factors such as changes in the market environment and competitive landscape. Investors are advised to pay attention to investment risks.

In addition, Sanwei Holdings has optimized and upgraded the BDO and degradable plastic integrated project (Phase II) constructed in Wuhai, and plans to invest in the construction of 700,000 tons/year BDO and 500,000 tons/year in Wuhai High-tech Industrial Development Zone. Annual biodegradable plastic PBAT, 240,000 tons/year high-end polyether material PTMEG, 100,000 tons/year NMP and supporting green power projects. After all the projects are completed, the total scale of Sanwei’s BDO integrated project will reach 1 million tons/year BDO, 600,000 tons/year PBAT, 300,000 tons/year PTMEG, 100,000 tons/year GBL and 100,000 tons/year NMP.

On April 12, 2022, the 300,000-ton/year BDO (1,4-butanediol) cycle of Inner Mongolia Sanwei New Materials Co., Ltd. was constructed by the Northwest Branch of China Chemical Engineering No.11 Construction Co., Ltd. The cooling tower of the water station has successfully completed the pouring and capping work, marking the completion of an important stage of the main project of the project.

On March 13, 2022, the BDO integration project (Phase I) of Inner Mongolia Sanwei New Materials Co., Ltd. (Abbreviation: Inner Mongolia Sanwei), a subsidiary of Sanwei Co., Ltd., was launched in the Wuhai Economic and Technological Development Zone, Inner Mongolia Autonomous Region. The carbon industrial park held a groundbreaking ceremony.

Project Overview

Inner Mongolia Sanwei New Materials Co., Ltd. BDO integrated project, the project is expected to have a total investment of 13 billion yuan, a total planned land area of ​​160 hectares, and a total planned construction scale of 900,000 tons/year of 1,4 butanediol (BDO), 600,000 tons/year degradable plastic PBAT, 300,000 tons/year high-end polyether material PTMEG, 1.8 million tons/year formaldehyde device, 100,000 tons/year electronic grade fine chemical product Y-butyrolactone (GBL) and 50,000 tons/year annual N-methylpyrrolidone (NMP), supporting a 1.2 million tons/year acetylene raw material (carbide) combined device.

The first phase of the project construction includes 300,000 tons/year 1,4-butanediol (BDO), 100,000 tons/year degradable plastic PBAT, 60,000 tons/year high-end polyether material PTMEG, and 600,000 tons/year formaldehyde device , supporting a 360,000 tons/year acetylene raw material (carbide) combined device, which is planned to be completed before May 30, 2023, and is ready for production.

The project has the characteristics of low energy consumption, high efficiency, low carbon and cleanliness. After the project is fully put into operation, it is expected to become an industry benchmark with leading scale, quality, energy consumption and efficiency, and is committed to creating advanced materials for coal chemical industry and functional polymers. , electronic-grade new materials’ integrated industrial chain, forming an industrial pattern of industrial complementarity, positive interaction, and coordinated development.
