On August 3, the Changqing ethane-to-ethylene project of PetroChina Lanzhou Petrochemical Company was put into operation and produced qualified ethylene products

This project is the first large-scale ethylene production unit in China built using the ethane cracking technology independently developed by PetroChina.
It uses the ethane component separated from the natural gas in Changqing Oilfield to process ethylene, which is more advanced than the traditional naphtha processing ethylene technology.
, has many advantages such as short process flow, small floor area, low equipment investment, high ethylene yield, low production cost, etc.
It is very important for optimizing the utilization of natural gas resources, improving the technical level of domestic ethylene production, promoting the high-quality development of the ethylene industry, and realizing upstream and downstream.
The integration and localization of large-scale key equipment "ethylene tertiary machine" and DCS control system, and the implementation of the "Made in China 2025" strategy have great leading and demonstration significance

The Changqing Ethane-to-Ethylene Project of Lanzhou Petrochemical Company is a key project for PetroChina to implement oil reduction and increase chemical conversion and realize transformation and upgrading

Under China's solemn commitment to the goal of "carbon neutrality" and "carbon peaking", Lanzhou Petrochemical Company has truly built the Changqing ethane-to-ethylene project into an environmentally friendly, green and low-carbon environment-friendly enterprise

The cracking furnace unit adopts the new flue gas denitration technology, which reduces the nitrogen oxide emission by 70% compared with the conventional cracking furnace unit, and realizes the ultra-low emission of exhaust gas;

Adopting the new technologies of catalytic oxidation treatment of waste alkali, ultrafiltration + reverse osmosis and evaporative crystallization, the deep reuse of wastewater has been realized, and the reuse rate has reached more than 95%

After the project is put into use, the carbon dioxide emission is about 342,400 tons per year, and the annual comprehensive energy consumption is 755,200 tons of standard coal (excluding ethane raw materials), reaching the world advanced level

The Changqing Ethane-to-Ethylene Project of Lanzhou Petrochemical Company 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 management platform for production control, safety and environmental protection, and an integrated electromechanical instrument to achieve high efficiency, intelligence and visualization.
It provides four capabilities of comprehensive perception, analysis and prediction, optimization of production, and coordinated execution, and forms integrated management of production scheduling, integrated management and control of electromechanical instruments, and integrated collaborative information management of emergency command.
An intelligent factory with networked, digitized, visualized, modeled and integrated superior capabilities
