China's petrochemical industry is accelerating its development, and expanding the scale of this sector will inevitably boost the demand for large-scale equipment. According to Wang Tingjun, a senior engineer at China Petroleum & Chemical Corporation (Sinopec), it is estimated that investment in petrochemical equipment will reach 30 billion yuan annually during the 11th Five-Year Plan period. He emphasized that Sinopec alone plans to invest 28 billion yuan each year in fixed assets during this time. When combined with investments from CNPC, CNOOC, and numerous local private petrochemical companies, the total annual investment across the entire industry could exceed 100 billion yuan.
Wang pointed out that under the guidance of intensive development and the "Guidance Catalogue for Industrial Structure Adjustment," smaller refining and ethylene plants—those with less than 8 million tons of annual refining capacity or 600,000 tons of ethylene output—are restricted from new construction. As a result, the push for large-scale equipment has become significant.
He highlighted several major projects across the three key groups. Sinopec is continuing with the expansion of its 10-million-ton refining facilities in Zhenhai, Maoming, Shanghai, Gaoqiao, Jinling, Yangzi, Qilu, Yanshan, and Guangzhou. The Maoming ethylene project, which will produce 800,000 tons annually, is under renovation with an investment of 4.3 billion yuan. In Fujian, a project involving 8 million tons of oil refining and 800,000 tons of ethylene is about to start, with an investment of 2.6 billion yuan. The Qingdao refinery, with a capacity of 10 million tons, has already begun with an investment of 11 billion yuan, while the Hainan project, involving 8 million tons of oil refining, is also underway.
CNPC is advancing multiple projects, including a 20-million-ton sulfur-containing crude oil refinery in Dalian, and 10-million-ton refineries in Lanzhou and Fushun. Meanwhile, Dushanzi and Changqing are preparing to start their 10-million-ton refineries. Jilin and Daqing are working on ethylene renovation projects, and several sites are preparing to build 800,000-ton ethylene units.
CNOOC has started the construction of a 12-million-ton refinery in Huizhou, with a total investment of 16.9 billion yuan.
Industry data shows that building a petrochemical plant requires between 500 million and 1 billion yuan, while a 10-million-ton refinery needs over 10 billion yuan. A million-ton ethylene plant demands more than 20 billion yuan in total investment.
Large-scale petrochemical projects, facility upgrades, and new installations all require advanced equipment. Wang stressed that expanding petrochemical equipment is not just about size—it involves significant improvements in design, manufacturing, inspection, transportation, on-site assembly, heat treatment, and material technology. Currently, China’s large-scale petrochemical equipment still struggles to meet the industry’s high-pressure, high-temperature, low-temperature, flammable, explosive, corrosive, and toxic conditions. There remains a gap in performance, quality, cost-effectiveness, safety, and environmental protection.
