In order to effectively utilize the surplus production capacity of some of the company's plants and maximize the benefits, Shanghai Petrochemical Company purchased related raw materials for blending in some plants to achieve increased production and efficiency.

In 2021, some units of the company are limited by the amount of raw materials, and the operating load has not been high, and the units have surplus capacity. The company sorted out the operation status of each unit and determined that resources such as cracked carbon 4, carbon 5 and cracked gasoline could be supplied to butadiene units, carbon 5 units and gasoline hydrogenation units for blending through purchased sources. To this end, the company actively takes the lead in promoting the relevant business process, negotiating and determining the appropriate purchase price, concluding the relevant purchase terms and implementing the contract signing work. Through the purchase of resources, the company increased production by 7.7 million yuan.

In addition, the company continued to carry out the petroleum coke replacement work, by tracking the petroleum coke market, in the case of a significant price difference between the imported petroleum coke purchased by the company and the self-produced coke produced by Shanghai Petrochemical, the company purchased imported coke at a low price into the factory, while increasing the sales volume of self-produced coke sold at a high price to achieve the replacement price difference, and achieved 55,000 tons of petroleum coke replacement in the year. With a benefit of 9.1 million yuan.
