In midwinter, a reporter visited the construction site of Inner Mongolia Yili Chemical Industry Co., Ltd., a key project in the Inner Mongolia Autonomous Region. The project involves the construction of a 1 million-ton-per-year PVC plant and a 400,000-ton-per-year ion-exchange membrane caustic soda facility, along with supporting infrastructure. The site was bustling with activity, as workers from the third, sixth, eleventh, and thirteenth construction companies under China National Chemical Engineering Corporation (Sinochem) were striving to complete the project on time for production, which was set to begin in October 2006. They were currently working on a vast 3,500-acre site.
According to Wang Yi, the general manager of Yili Company, the project was jointly funded by Yili Resources Group, Shanghai Huayi Group, and Shenhua Group, with a total investment of 4 billion yuan. Yili Group has significant strengths in heavy chemical industry, coal chemical industry, organic and inorganic chemistry, salt chemical industry, as well as resources, capital, and environmental management. Shanghai Huayi is one of China's largest PVC manufacturers, known for its advanced technology and skilled workforce. Shenhua Group, the country's largest coal company, also possesses import-export rights and operates in coal-electricity integration, shipping, railways, and ports.
Feng Guangtian, deputy general manager of Yili Company, highlighted the project’s advantages in raw materials, power, water, and human resources. He noted that demand for PVC in China would remain strong in the coming years, with domestic production capacity and technology struggling to keep up. As a result, large quantities of PVC are still imported. Currently, Inner Mongolia’s PVC production capacity is around 200,000 tons per year, leaving a significant market gap. The Yili project aims to utilize local coal gangue resources efficiently, ensuring cost competitiveness. The project is planned in two phases, with the first phase involving 400,000 tons/year of PVC and 400,000 tons/year of caustic soda. Construction began in April 2005, with completion expected in October 2006. By 2010, the full capacity of 1 million tons/year is anticipated, making it the largest single-project PVC facility in China.
Despite the cold weather in Erdos during the visit, the construction site remained active, with workers braving the wind to work inside towering equipment areas. The first phase of the project was undertaken by Sinochem’s third, sixth, eleventh, and thirteenth construction companies.
Sinochem Shijianjian was responsible for several critical components, including desalination water supply, polymerization, chemical preparation, wastewater treatment, VCM monomer recovery, product packaging, electrical systems, and storage facilities. Since the project began last June, the team has overcome numerous challenges and made steady progress.
Sinochem Sanjian constructed the cooling tower, chimney, and acetylene plant. They implemented strict safety protocols and performance evaluations, ensuring a safe and controlled environment with zero accidents.
Sinochem Shihua Chemical Construction handled the circulating water system, water purification station, captive power plant, and coal transportation. Their work has been consistently smooth and has received high praise from the client and supervisory units.
