In March, Zhenhai Refining and Chemical Co., Ltd. solidly carried out the theme action of "remember the entrustment, make new contributions, create new achievements, and welcome the 20th National Congress", and seized the opportunity of strong ethylene market demand. Quickly adjust the product structure, stop the No. 3 polyethylene unit, and increase the output of ethylene monomer with significant synergies.

Zhenhai Refinery kept in mind General Secretary Xi Jinping's ardent entrustment of "world-class, high-tech, and integration", combined with the group company's theme action requirements, sorted out 59 key tasks and 206 major measures, adopted project-based management and supervised the whole process, and continued to optimize. In terms of production and operation, we explored the establishment of an optimization model under the new integrated structure. In the first quarter, we processed 6 million tons of crude oil and produced 506,000 tons of ethylene, ranking first among refining and chemical enterprises in terms of efficiency in the first quarter.

As the first-phase project of Zhenhai Base is fully put into operation, and 11 sets of main units have entered the production sequence, the company's optimization team continues to explore and establish an optimization model under the new integrated structure, and promote the integration between the new area and the old area of ??Zhenhai Base, as well as between the refining and chemical businesses. Collaborative optimization. In terms of oil refining, optimize the rhythm of crude oil procurement, strengthen the management of crude oil demurrage, optimize the crude oil processing plan, and strive to increase the crude oil processing volume; continue to promote "if oil is suitable for oil, ene is suitable for ene, and aromatic is suitable for fragrant", and hydrogenated naphtha is well prepared. Optimize the flow direction of oil, residual hydrogenated naphtha, atmospheric and vacuum naphtha. In terms of chemical industry, adhere to the market orientation, continue to optimize the structure of ethylene raw materials, dynamically adjust the benefit ranking of ethylene raw materials, improve the operating economy of the two sets of ethylene plants, and make the optimization model under the new integrated structure more perfect. At the same time, formulate and implement an annual energy efficiency improvement plan, and achieve energy saving and consumption reduction through measures such as joint optimization of upstream and downstream devices.

In March, as the market demand for asphalt, naphtha, jet fuel and other products decreased, Zhenhai Refinery adhered to market orientation, continuously optimized product structure, reduced asphalt production, and increased the coking unit load. The effect is remarkable. Flexibly adjust the production plan, produce more gasoline and less naphtha, change the jet fuel component to diesel as much as possible, do a good job of full production, full sales, fast production and fast sales, and strive to maximize benefits. Adhere to the linkage of production, sales, research and application, increase research and development of new products, and continue to optimize the structure of polyolefin products. In the first quarter, 160,000 tons of new polyolefin products and special materials were produced, accounting for 61.5% of the total output of polyolefin, with obvious differentiation and efficiency increase.

At the same time, Zhenhai Refinery has strengthened cooperation with 23 joint ventures and cooperative enterprises in Zhenhai Base and enterprises in the park, and has formed a new pattern of "1+23+N" integrated development. Implementation and integrated assessment" thinking, coordinating the plan management, operation optimization, raw material procurement, product sales and other work of member enterprises to maximize the overall benefit. They have achieved mutual supply of materials with more than 20 enterprises in the chemical park. More than 460 kilometers of inter-plant pipelines are closely connected with the park. With large ethylene as the leader and pipelines as the medium, an integrated pipeline transportation and logistics system in the park has been formed. In the first quarter, the mutual supply of products and materials between Zhenhai Refinery and Chemical Park exceeded 800,000 tons, which effectively drove local economic development.
