Dazhou vulcanization industry ready to go

On April 4, Dazhou hosted the launch ceremony of the PetroChina-Chevron-Chuanchuan Northeast cooperation project and the opening of Unocal Donghai Co., Ltd. This event marked the official start of China’s largest onshore oil and gas cooperation project—the high-sulfur gas development initiative in Northeast Sichuan. Expected to begin production in 2009, the project aims to produce 2 billion cubic meters of natural gas annually by 2010, increasing to 6 billion cubic meters by 2013. Dazhou is rich in natural gas resources, with an estimated 3.8 trillion cubic meters of reserves and 660 billion cubic meters of proven reserves. The region's natural gas is characterized by high production, high pressure, and high sulfur content, with some wells containing up to 17% hydrogen sulfide. To manage this, CNPC and Sinopec are constructing five gas purification plants in the area. By 2010, sulfur production from Dazhou’s natural gas is expected to reach 4.5 million tons, accounting for half of China’s total sulfur output and making it Asia’s largest sulfur production base. Seizing the opportunity presented by the development of sulfur resources, Dazhou has focused on expanding its natural gas industry chain, promoting sulfur-based industries, and transforming resource advantages into economic benefits. As a result, the city has become a major hub for vulcanization and sulfur processing. To further boost its sulfur industry, Dazhou plans to establish a 30-square-kilometer natural gas energy and chemical industrial zone. The city is actively attracting foreign investment and encouraging large companies to set up operations there. So far, eight projects have been completed, and the vulcanization industry has become a key component of the chemical park. International multinationals have shown strong interest in deepening the processing of natural gas-derived chemicals, providing Dazhou with access to advanced capital, technology, and management practices. In recent years, Dazhou has prioritized the development of its natural gas chemical industry. Advanced technologies, particularly in desulfurization, sulfur recovery, and tail gas treatment, have been widely adopted. The city also utilizes state-of-the-art automation systems, achieving sulfur recovery rates over 99.8% and purity levels reaching 99.99%. To address the challenges of low-value sulfur products and inefficient processing, Dazhou is reorganizing its sulfur product layout, seeking new markets, and focusing on deep processing. The city has partnered with institutions like China University of Petroleum (Beijing) and Southwest Petroleum University to develop sulfur-based chemical technologies and strategies. With government support and collaboration with Sinopec and PetroChina, Dazhou is working to establish a sulfur chemical engineering technology center. Currently, the city is focusing on developing high-potential products such as polymer sulfur, dimethyl sulfoxide, sulfur-concrete, and sulfur-asphalt—products that offer environmental benefits, high economic returns, and reduced investment risks. These efforts aim to achieve comprehensive sulfur utilization, protect the environment, and enhance overall economic efficiency. Dazhou is steadily becoming China’s leading sulfur processing base, setting a new standard for sustainable and high-tech industrial development.
