Successful Commissioning of First in China Integrated Coal, Oil and Gas-based Olefins Production Project

After three years of construction all units of the integrated coal, oil and gas resources conversion project at the Yanchang Jingbian Chemical Park, the investment of which totals 27 billion RMB, have been operating to deliver the on-spec PE and PP products, symbolizing the successful start-up of the first in the world integrated coal, oil and gas conversion project.

This project is the energy chemical project, the initial investment scale of which is the largest in the Shaanxi province, and is also the first in the world giant integrated project for manufacture of olefins from coal, oil and gas resources. The said project mainly includes an 1.8 Mt/a methanol unit, an 1.5 Mt/a unit for catalytic pyrolysis of residue, an 1.2 Mt/a polyolefins unit and other five units, among which the syn-gas compressor train of the 1.8 Mt/a methanol unit is the largest machine in the world. The methanol-to-olefins technique, the heavy oil catalytic pyrolysis technology, and the gasification process of water-coal slurry made from multiple feedstocks are all Chinese independent proprietary innovative technologies which have assumed an internationally leading position.
