    On August 3, good news came from the start-up headquarters of the Changqing Ethane to Ethylene Project of PetroChina Lanzhou Petrochemical Company.
    The 800,000 tons/year ethylene plant was put into operation on August 2.
    Produce qualified ethylene products
    .


    This indicates that the Changqing Ethane-to-Ethylene Project under the joint efforts of Lanzhou Petrochemical Company and all participating units, after two years of arduous hard work, successfully achieved the planned node goal and achieved a successful start-up


    Ethane is the highest quality raw material for ethylene cracking
    .


    The Lanzhou Petrochemical Company's Changqing Ethane to Ethylene Project is the first large-scale ethylene production unit in China built using the ethane cracking technology independently developed by PetroChina


    The Lanzhou Petrochemical Company Changqing Ethane to Ethylene Project is located in Yulin City, Shaanxi Province, the core area of ​​China Energy and Chemical’s "Golden Triangle".


    , 400,000 tons/year full density polyethylene, 30,000 tons/year butene-1/hexene-1 flexible switching device and related public works, supporting auxiliary facilities


    The project aims at the international advanced level, benchmarks against the advanced indicators of world-class enterprises, and breaks through the traditional ethylene production constraints of high energy and material consumption and low ethylene yield.


    The ethylene yield can be increased from about 30% of cracked naphtha to 80%.


    Under China’s solemn commitment to carbon neutrality and carbon peak goals, Lanzhou Petrochemical Company has truly built the Changqing Ethane to Ethylene Project into an environmentally friendly, green and low-carbon, environmentally friendly enterprise
    .


    The cracking furnace device adopts a new type of flue gas denitrification technology, which reduces the emission of nitrogen oxides by 70% compared with the conventional cracking furnace device, and realizes ultra-low emission of exhaust gas; adopts catalytic oxidation treatment of waste alkali, ultrafiltration + reverse osmosis and new technology of evaporative crystallization, waste water The recycling rate has reached more than 95%, making it the first refining and chemical project of PetroChina with nearly zero discharge of wastewater


    At the same time, the project makes full use of advanced information technologies such as big data and cloud computing, and integrates the advantages of communication and mobile platforms to build a production control, safety and environmental protection, and mechanical and electrical integration management platform to achieve efficient, intelligent and visual data integration and sharing.


    The four capabilities of comprehensive perception, analysis and forecasting, optimization of production, and coordinated execution have formed the integrated management of production scheduling, integrated management and control of mechanical and electrical instruments, and integrated coordinated information management methods for emergency command, and have established strong automation, networking, digitalization, and visualization.
    , Intelligent factory with superior capabilities of modeling and integration


      According to reports, the project has a total investment of 10.


    4 billion yuan.
