Basic project overview: Total investment of 21.307 billion yuan, on-site upgrading in the plant area

The project construction unit is Sinopec Shanghai Petroleum & Chemical Co., Ltd. The project is located in the existing plant area in Jinshan District, Shanghai, with no new land required. The total investment is 21.307 billion yuan, all funded by the enterprise itself. The main construction period of the project is about 3 years, and the longest supporting facility construction period is about 5 years.

The project will maintain the annual refining capacity of 14 million tons unchanged. Through optimizing the device structure, eliminate a batch of outdated units including the 700,000 t/a ethylene unit, and build new 1.2 million t/a ethylene and downstream new material units, so as to enhance the overall security and ecological preservation level of the plant area.

Device iteration: Alternation of old and new refining and chemical production capacities

Refining sector

7 new refining units will be built, 3 existing units will be renovated, and 8 outdated refining units will be shut down. The key new units include 3 million t/a hydrocracking unit, 200,000 NM³/h POX hydrogen production unit, 2×80,000 t/a sulfur recovery unit, sour aquatic environments stripping unit, MTBE/butene-1 unit and others; the hydrocracking unit, gasoline adsorptive processes desulfurization unit and gaseous fractionation unit will be renovated.

Chemical sector

8 new chemical units will be built, 2 units will be renovated, and a total of 10 outdated chemical and supporting units will be shut down. The key new units include 1.2 million t/a ethylene, butadiene extraction, cracked gasoline hydrogenation, aromatics extraction, vinyl acetate, polyethylene, carbonate, C5 separation units; the C5 separation and ethylene glycol units will be renovated simultaneously, and outdated production capacities such as ethylene, butadiene extraction and polyester will be eliminated.

Significance of the project

This project is a typical refining and chemical "minimize oil, increase chemical" transformation, which relies on the existing plant area to carry out production capacity replacement, minimize oil product output, and expand the supply of new material items such as ethylene, polyolefins and C5 complete utilization. The finalization of all the foundation pile bidding sections creates preconditions to subsequent civil construction and equipment installation, and promotes the transformation of Shanghai Petrochemical towards high-end new materials.
