PX Project Domestic Investment Blocked Overseas

In recent months, a public protest erupted in Maoming City, Guangdong Province, against the local p-xylene (PX) project. In response, the Maoming City government stated that the aromatics project is still in the stage of public education and it's too early to start construction. This comes as the world’s largest PX plant was recently commissioned in Singapore, with one of its major shareholders being a Chinese chemical fiber and textile company. Over the past seven years, the PX project has been a recurring source of controversy across China, from Xiamen to Dalian, Kunming, and Maoming. Some projects have been delayed or postponed, while the rapid growth of downstream products like PTA has widened the domestic supply gap. Currently, more than half of the PX demand is met through imports. To address this, some large downstream manufacturers are exploring options to build overseas refineries and aromatics plants, aiming to produce their own PX and reduce dependency on foreign sources. This trend highlights the growing pressure on the industry to secure stable supply chains. PX, also known as para-xylene, is a colorless and transparent liquid commonly used in the production of terephthalic acid (PTA), dimethyl terephthalate (DMT), and polyester. It also serves as a raw material for solvents, pharmaceuticals, perfumes, and inks. According to Bian Huihui, an analyst at Treasure Island, global PX production has surged due to rising demand for polyester fiber. From 2010 to 2012, global PX capacity increased from 34.445 million tons to 39.99 million tons, with Asia accounting for about 79% of the total. The region remains the primary hub for PX production, driven by concentrated PTA manufacturing. As of 2013, 83% of global PTA capacity was located in Asia, further reinforcing the region’s role in the PX market. Despite global overcapacity, China continues to face a significant PX shortage. Domestic PX capacity stands at around 11.51 million tons per year, but demand exceeds supply, with imports playing a crucial role. In 2013, China imported approximately 9 million tons of PX, while domestic production reached only 7.4 million tons. With new PTA projects coming online, the demand for PX is expected to grow further. While the global PX market is expanding, particularly in South Korea, the Middle East, and Southeast Asia, the situation in China remains distinct. Major players like Sinopec, PetroChina, and CNOOC control most of the domestic PX production, giving them strong pricing power. However, the imbalance between PX supply and PTA demand continues to create challenges for the industry. Some PTA companies are now looking to integrate vertically by investing in overseas PX facilities, aiming to cut costs and ensure a stable supply chain. One example is Hengyi Petrochemical, which received approval to invest in a $4.32 billion petrochemical project in Brunei. This move reflects a broader strategy among Chinese firms to gain greater control over upstream resources. The controversy surrounding PX projects also highlights public concerns about environmental safety. Despite efforts to correct misinformation, such as changing the toxicity rating of PX on Baidu Encyclopedia, many people remain wary of new projects near residential areas. This sentiment poses a challenge for future expansion. As the industry evolves, the balance between supply, demand, and public perception will continue to shape the future of PX in China.
