The first pile of Phase I Project was driven into the ground in 1974 and the project was completed and put into operation in 1976 with 18 major plants for the production of ethylene, polyester fibre, PVA fibre, acrylic fibre and plastics. The completion of this project contributed to the promotion of China’s mastering new technology in petrochemical and synthetic fibre industry, producing on its own petrochemical products, speeding up the development of synthetic fibre industry and resolving the problem of not enough clothing for the people.
The construction of Phase II Project was started in 1980 and completed in 1985. The project includes 10 production plants, adding 200,000 tons of synthetic fibre feedstock to the existing capacity, quite substantially increased the production capacity.
The construction of Phase III Project was started in1987 and fully completed in 1992, primarily including 7 production plants with 300,000 T/Y Ethylene Plant as the key item. The completion of this project turned Shanghai Petrochemical Complex into the largest vertically integrated petrochemical production base in China at that time.
In 1993, the successful completion of joint stock system reform turned the former Shanghai Petrochemical Complex into Shanghai Petrochemical Co., Ltd. The joint stock system helped the Company to take the lead in the establishment of the basic framework of a modern enterprise system in China's petrochemical industry and blaze a new trail for the reform of state-owned enterprise (SOE) conforming to the Chinese reality and with its own characteristics.
The construction of Phase IV Project was commenced in 2000 and fully completed in 2002. This project was characterized by tapping potentials and technical revamping with 700,000 T/Y ethylene expansion project as the core. The completion of this project helped the Company make a significant step forward in its production scale, technical competence, product quality, sales revenue and comprehensive competitiveness.
From 2003 to 2009, the Company carried out the construction of Structural Adjustment Project (Phase V Project) with optimizing structure and realizing sustainable development as the theme. This project includes the refining de-bottlenecking projects such as 3,300,000 T/Y Diesel Hydrogenation Plant and 1,200,000 T/Y Delayed Coking Plant and the intermediate feedstock comprehensive utilization projects such as 600,000 T/Y PX Aromatics Complex, 150,000 T/Y C5 Fractions Separation Plant and 380,000 T/Y Ethylene Glycol Plant, as well as a number of energy-saving and environmental protection projects. With the completion of the Structural Adjustment Project, the Company can further optimize its resources utilization and products mix, maintain the comprehensive competitive advantage of being vertically integrated and enhance the competitiveness of the Company in aspects of scale, cost, technical content and product quality.
