The PTA (Purified Terephthalic Acid) market has experienced a steady upward trend in recent years, driven by growing demand and rising oil prices. Currently, the domestic price of PTA stands at 12,000 yuan per ton. As the world's largest PTA market, China consumed over 10 million tons in 2005, with approximately 52% sourced domestically. By 2010, demand is projected to reach 17 million tons, highlighting the industry's significant growth potential.
Since the start of the 21st century, China’s PTA sector has expanded rapidly, with both production capacity and output increasing substantially. In 2001, annual production was under 2.2 million tons, but by 2005, it had surged to about 5.5 million tons, reflecting an average annual growth rate of over 25%. Despite this progress, domestic supply still falls short of demand, leading to a growing import gap. In 2005, imports reached nearly 6.5 million tons, underscoring the need for further expansion and investment.
International players have been actively entering the Chinese PTA market. For instance, after completing its second phase, Zhuhai BP will have an annual PTA capacity of 1 million tons, joining Yangzi and Xianglu in a competitive three-way position. Looking ahead, Zhuhai BP plans to build four PTA facilities with a combined capacity of over 2.5 million tons per year, aiming to become the world's largest PTA production base. Meanwhile, Japan’s Mitsui Chemicals is investing $300 million in a 600,000-ton/year facility in Zhangjiagang, which will be completed in 2007 and expanded to 1.2 million tons by 2010. Similarly, Jiangsu Sanfangxiang and Taiwan’s Tenglong are constructing a 600,000-ton plant, while Mitsubishi and CITIC have invested around $1 billion in a 2.6 million-ton PTA project.
Domestic companies are also expanding their capacities. Yizheng Chemical Fiber, with an existing 900,000-ton/year PTA facility, plans to add another 900,000 tons by 2008. Yangzi Petrochemical is building a new 450,000-ton plant, raising its total capacity to 1.2 million tons. By 2010, Jiangsu Province is expected to account for 35.5% of China’s total PTA production, making it the country’s leading PTA producer. Sinopec, with over 2.5 million tons/year of PTA capacity, ranks as the world’s second-largest producer after BP, which has a total capacity of 6.5 million tons.
Currently, 70% of China’s PTA production is controlled by Sinopec and PetroChina, with the remaining 30% coming from joint ventures like Xiamen Xianglu and wholly-owned entities such as Zhuhai BP. However, rising oil prices and rapid expansion in the chemical fiber industry have led to tighter raw material supplies, creating opportunities for private enterprises to enter the petrochemical sector.
Despite the positive outlook, experts caution that China’s PTA industry remains uncertain. The sector is heavily dependent on foreign technology and raw materials, particularly PX and hydrocarbon equipment, which are weakly developed domestically. This dependency could lead to supply chain vulnerabilities if investments grow too quickly, potentially resulting in oversupply and financial instability.
Experts also note that while PTA manufacturing is highly active, there is doubt about whether demand will sustain such rapid growth. Additionally, unclear profitability and high production costs pose challenges. Some believe that adopting advanced technologies from BP or Sinopec can increase production efficiency and reduce costs, but large-scale projects carry higher risks.
To address these issues, the government has tightened approvals for new PTA projects to prevent overcapacity and ensure sustainable development. Industry leaders emphasize the importance of considering upstream raw material limitations, downstream demand, and technological challenges when planning new projects.
Developing independent PTA technology is critical. Currently, most PTA technology is imported, with companies like BP, DuPont, and Mitsui holding key patents. China pays $30 per ton in patent fees, which significantly impacts production costs. However, efforts to localize technology have made progress. Sinopec’s “Ten Dragon†project, led by Yangzi Petrochemical, has developed proprietary PTA technology, reducing energy consumption and improving efficiency. Sinopec Shanghai Petrochemical has also achieved breakthroughs in localizing PTA technology, breaking foreign monopolies and saving millions in costs.
Energy efficiency remains a major challenge. Under the “Eleventh Five-Year Plan,†the PTA industry must reduce energy consumption, and many older plants have significant energy-saving potential. For example, Yangzi Petrochemical’s upgraded PTA unit reduced energy use from 280 kg of standard oil/ton to 150 kg/ton, saving nearly 300 million yuan annually.
Environmental concerns are also rising, as many PTA plants are located along the Yangtze River and coastal areas, posing risks of water pollution and ecological damage. Regulatory bodies have identified deficiencies in risk management and emergency response measures.
Finally, the manufacturing of megaton-scale PTA equipment remains challenging. While domestic companies have made progress, key components like heavy-duty turbines and large centrifuges are still largely imported. Experts stress the need for coordinated research, design, and quality control to achieve full localization of major equipment.
In conclusion, while China’s PTA industry shows strong growth potential, it faces significant challenges related to technology dependence, environmental impact, and sustainable development. Balancing investment with demand and ensuring technological independence will be crucial for long-term success.
