On March 14, reporters learned from Jinxi Petrochemical that the company continues to implement the strategic initiatives of \"reducing oil content and increasing chemical products,\" \"reducing oil content and increasing specialty products,\" and \"reducing oil content and increasing green products.\" Keeping up with market trends, it has repositioned its petroleum coke products, and while ensuring that the product quality meets 3A standard, it is actively working on improving product quality through technical innovations. Since the beginning of this year, over 50,000 tons of petroleum coke have been produced. As a by-product of the petroleum refining process, petroleum coke is one of the main materials used in the production of anodes for new energy lithium batteries. In recent years, the new energy vehicle industry has seen rapid development. Jinxi Petrochemical has focused on the demands of the new energy market and actively explored pathways for green development. Increasing the production of petroleum coke has become a key measure for alleviating the pressure on the company’s refined oil output and achieving the goal of “reducing oil production while increasing the output of specialty products”. To improve the quality of petroleum coke products, Jinxī Petrochemical has carried out technical exchanges with the Petrochemical Research Institute in areas such as raw material pretreatment technology and process optimization for coking units, focusing on optimizing coking raw materials and key analysis indicators as the next steps. The company makes full use of the critical role that process simulation plays in process optimization and technological innovation. By simulating changes in the sulfur content of crude oil and petroleum coke, it identifies the critical value for the sulfur content in crude oil, thereby enabling the improvement of the quality of petroleum coke. Jinxī Petrochemical adjusted the processing capacity of its delayed coking unit and the load on the heating furnaces; by increasing the unit’s circulation ratio and controlling the temperature at the top of the distillation tower as well as the temperature at the outlet of the heating furnaces, it ensured that the coking reaction proceeded properly ； By operating the \"two furnaces and four towers\" in parallel, the plant’s capacity to process raw materials is increased, thereby raising the production of petroleum coke. Meanwhile, Jinxi Petrochemical has adjusted its sales strategies flexibly in light of the domestic surplus of refined oil products and the strong demand for petroleum coke, focusing on strengthening the brand image of low-sulfur petroleum coke in order to become a benchmark in the regional market. “Currently, the coking plants in western Liaoning all promote the ability to process the petroleum coke produced by Jinxi Petrochemical as a key selling point. ”said Du Heng, deputy head of the Comprehensive Management Group in the Marketing and Transportation Department of Jinxi Petrochemical. Next, Jinxi Petrochemical will continue to work together with research institutions to study the impact of crude oil properties on the quality of petroleum coke, establish a database, and implement segmented production of petroleum coke, aiming to produce 2B and 2A grade petroleum coke by the first quarter.
