en.Wedoany.com Reported - Blue Ocean New Materials (Tongzhou Bay) Co., Ltd. recently published an environmental impact assessment public consultation notice for its project on comprehensive utilization of ethane/light hydrocarbons to produce high-end chemical new materials. Located in the Tongzhou Bay Green Chemical Expansion Zone (Main Port), the project has a total investment of 22,240.49 million yuan. It is a key initiative promoted by a subsidiary of China National Petroleum Corporation (CNPC) established in 2024, aiming to expand the high-end market in East China and promote the healthy development of China's new materials industry.
The project will construct an ethylene plant using self-owned and imported light hydrocarbons such as ethane and LPG as feedstock. The feedstock is light and high-quality, resulting in low ethylene production costs and strong product competitiveness. Main construction includes a 1 million t/a ethylene cracking unit, a 200,000 t/a cracked gasoline hydrogenation unit (including aromatics extraction), a 400,000 t/a FDPE unit (gas-phase method), a 200,000 t/a FDPE unit (liquid-phase method), a 60,000 t/a butadiene extraction unit, a 60,000/20,000 t/a MTBE/butene-1 unit, a 50,000 t/a low-cis polybutadiene rubber unit, a 100,000 t/a POE unit (gas-phase method), a 200,000 t/a synthetic ammonia unit, a 300,000 t/a PP unit, and supporting utilities and auxiliary facilities.
The ethylene plant adopts a three-motor electric drive design, effectively improving the electrification rate and achieving significant CO2 emission reduction under green electricity coupling conditions. Downstream products mainly consist of high-end new materials such as polyolefin elastomers, aiming to achieve high product value, enhance industrial chain resilience, and improve profitability. All production units utilize CNPC's self-developed processes, selecting mature, advanced, economically reasonable, efficient, and clean process technologies in the design, intended to break through foreign monopoly technical barriers.
The POE unit produces ethylene-octene copolymer, while the FDPE (solution-phase octene copolymerization) unit produces metallocene polyethylene. Currently, the overall construction progress of the high-end polyolefin new materials project being built by Blue Ocean New Materials (Tongzhou Bay) Co., Ltd. has reached 91.2%.
