en.Wedoany.com Reported - As of June 2, Lanzhou Petrochemical Company's ethylene output this year has reached 657,000 tons, with cumulative ethylene output surpassing the 20 million ton mark. As an important basic chemical raw material, 20 million tons of ethylene can support the production and supply of over 30 billion food packaging items, tens of billions of textile and apparel products, and nearly 500 million television casings.

In ethylene production, Lanzhou Petrochemical adheres to the principle of "large-scale stability yields large-scale benefits," implementing a series of refined measures in raw materials, operations, and management. It has continuously improved and implemented the "separate storage and separate cracking" operation mode for the topping oil system, classifying and cracking raw materials of different properties to reduce the frequency of online raw material switching and effectively increase ethylene yield. It has innovatively applied a time-series large model to shift device operations from empirical judgment to predictive dynamic adjustments, making operating parameters more precise.

In recent years, Lanzhou Petrochemical has built and put into operation an 800,000-ton/year ethane-to-ethylene unit using China National Petroleum Corporation's proprietary technology, completing four technological iterations from "grain-to-coal chemical industry—dry gas-to-ethylene—heavy oil cracking—ethane-to-ethylene," achieving independent control over key core technologies. Through years of tackling core ethylene technologies, Lanzhou Petrochemical has overcome over a hundred key challenges and independently developed multiple complete technology systems with full independent intellectual property rights. Meanwhile, in optimizing the ethylene product structure, it continues to extend the high-end industrial chain, cultivating and building multiple high-value-added industrial chains such as high-end polyolefins and synthetic rubber, gradually forming a new industrial development pattern of "basic raw material supply + high-end material breakthroughs."
