CNPC builds a 1.2 million-ton ethylene mega-factory. The main construction works and units include: a newly built 1.2 Mt/a ethylene cracker, 400 kt/a HDPE (high-density polyethylene), two sets of 400 kt/a FDPE (full-density polyethylene), and 1.3 Mt/a CCUS unit, totaling 12 sets of process units. Auxiliary production facilities, on-site public engineering works, off-site special railway lines and living bases will also be constructed as supporting facilities.
Adopting the ethane cracking process for ethylene production, the ethylene yield reaches 80%. Energy consumption is more than 30% lower than that of the traditional naphtha route. The supporting 1.3 Mt/a CCUS unit enables low-carbon production.
Domestic technologies are independently developed with a localization rate of 99%, driving the new energy industry chain in Northwest China and achieving a win-win situation for environmental protection and profitability!
