China National Petroleum Corp. has started up a 600,000-tonne/year ethylene unit that doubles capacity of Daqing Petrochemical with the country’s first ethylene plant based on domestically developed technology.

The project is part of a national push to increase ethylene production capacity (OGJ Online, May 19, 2009).

CNPC subsidiary China Huanqiu Contracting & Engineering Corp. developed pyrolysis technology and front-end depropanization and front-end hydrogenation separation technologies for the project.

“This enables China to be independent from importing technologies for ethylene production which lasted for half a century,” CNPC said in a press statement.
