Sinochem News News 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 domestic large-scale ethylene production unit built using the ethane cracking ethylene technology independently developed by PetroChina.
It uses the ethane component separated from the natural gas in the Changqing Oilfield to process ethylene, which is better than traditional naphtha processing ethylene technology.
, Has many advantages such as short process flow, small floor space, low investment in equipment, high ethylene yield, low production cost, etc.
, which can optimize the use of natural gas resources, improve the domestic ethylene production technology level, promote the high-quality development of the ethylene industry, and achieve upstream and downstream The integrated, large-scale key equipment "Ethylene Three Machines" and the localization of the DCS control system, and the implementation of the "Made in China 2025" strategy has great leading and demonstration significance

The Lanzhou Petrochemical Company’s Changqing Ethane to Ethylene Project was listed as a national demonstration project for ethane cracking to ethylene by the National Development and Reform Commission and the Ministry of Industry and Information Technology.
PetroChina completed its first large-scale refining and chemical project during the 14th Five-Year Plan period
.

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