Lanzhou Petrochemical Company’s Ethylene Transformation Project for Transformation and Upgrading: This is a renovation and expansion project located in the Xigu Chemical Industrial Park in Lanzhou, which was established with provincial approval. It involves the refining complex and the chemical plant area of Lanzhou Petrochemical Company. The total investment in this project is approximately 23.17 billion yuan. The renovation plan for this project can be divided into three parts: 1) Ethylene renovation: By shutting down the existing 240,000 tons/year ethylene plant, removing the cracking, quenching, compression, and propylene units from the existing 460,000 tons/year ethylene plant, and constructing a new 1.2 million tons/year ethylene cracking + quenching + cracked gas compression + propylene production unit along with an 800,000 tons/year cold separation system; meanwhile, the cold separation system of the 460,000 tons/year ethylene plant will be reused, thereby creating an ethylene production system with one input and two outputs. 2) Refining upgrade: After the implementation of this project, the types of crude oil processed and the processing volumes in the refining system will remain unchanged. By carrying out adaptive upgrades to three existing units—namely, a 1.2 million tons/year catalytic cracking unit, a 3 million tons/year diesel hydrogenation unit, and another 1.2 million tons/year diesel hydrogenation unit—it is possible to increase the supply of raw materials for ethylene production. At the same time, new PSA units and carbon dioxide recovery units will be built. 3) Downstream chemical industry support: 7 new production units will be built (20,000 tons per year of octene-1, 100,000 tons per year of POE, 140,000 tons per year of EVA, 450,000 tons per year of high-density polyethylene, 400,000 tons per year of polypropylene, 700,000 tons per year for the hydrogenation of pyrolysis gasoline, and 700,000 tons per year for aromatic extraction); meanwhile, the existing 170,000 tons per year high-density polyethylene plant will be converted into a plant capable of producing 60,000 tons per year of ultra-high molecular weight polyethylene. As a result of the implementation of the ethylene transformation project aimed at the transformation and upgrading of Lanzhou Petrochemical Company, its output of refined oil products will be reduced to 5.3049 million tons per year; the production of gasoline and diesel will decrease by 1.3907 million tons per year, while the output of aviation fuel will remain unchanged. At the same time, the production capacity of new chemical materials will be increased by 2.0092 million tons per year (of which 140,000 tons per year will be for EVA, 100,000 tons per year for POE, 50,000 tons per year for ultra-high molecular weight polyethylene, and 1.035 million tons per year for high-end materials such as metallocene polyethylene and metallocene polypropylene), with the goal of establishing a production base capable of producing millions of tons of such new materials as planned. The implementation of the ethylene transformation project for the transformation and upgrading of Lanzhou Petrochemical Company will overcome the technical barriers associated with octene-1, POE, and high-end polyolefins such as polypropylene, thereby enabling CNPC to industrialize its own proprietary technologies. This transformation effort focuses on both energy savings and carbon reduction, aiming to achieve high-quality development for Lanzhou Petrochemical Company in terms of transformation and upgrading, as well as sustainability, low carbon emissions, and environmental protection.
