On the north wing of the Yangtze River estuary, a new material base carrying the ambitious transformation of energy central enterprises is awakening. Blue Ocean New Materials (Tongzhou Bay) Co., Ltd., which was registered and established in 2024, has just unveiled its first major project - the comprehensive utilization of ethane/light hydrocarbons to produce high-end chemical new materials project, which has officially entered the stage of environmental impact assessment publicity.

This is not only a heavy drop for the Tongzhou Bay Green Chemical Expansion Zone, but also a key chess piece set by China National Petroleum Corporation in the East China region.

Building a cornerstone with billions of investment

The project is located in the Tongzhou Bay Green Chemical Expansion Zone, with a total investment of 22.2 billion yuan. Based on the reserved land in the existing factory area, a modern chemical new city will move from blueprint to reality.

Its core is a 1 million ton/year ethylene cracking unit, which is the "heart" of the entire industry chain. Around this heart, a huge supporting system has been built for the project: a 200000 ton/year cracking gasoline hydrogenation unit will "squeeze out" the by-product aromatic hydrocarbons; Downstream, two sets of FDPE units using different processes have been precisely deployed, with a total polyolefin production capacity of 600000 tons, providing the market with diversified basic materials.

At the same time, facilities such as 60000 tons/year butadiene extraction and 60000 tons/year MTBE/butene-1 will effectively extend the industrial chain and improve resource utilization efficiency. The synchronous construction of public works and auxiliary facilities provides a solid guarantee for the smooth operation of this' chemical city '.

Technological breakthrough and breaking through monopoly

Another major highlight of the project is its ability to overcome the bottleneck technology. All production facilities are locked in China Petroleum's independently developed process technology, aiming to break through foreign technological barriers. The most notable ones are the 100000 tons/year gas-phase POE (polyolefin elastomer) plant and the FDPE plant using solution based octene copolymerization process.

These devices will produce high-end products such as high value-added metallocene polyethylene and ethylene octene copolymers. In the past, such high-performance materials relied heavily on imports. Now, PetroChina is trying to leave a Chinese mark in this high-tech field through independent innovation. The addition of 300000 tons/year PP plant and 50000 tons/year low cis rubber plant further enriches the product matrix of high-end synthetic resins and synthetic rubber.

Green Intelligent Manufacturing Plastic Benchmark

Under the dual carbon target, the green genes of the project are particularly prominent. On the raw material side, the project extensively uses self owned and imported light raw materials such as ethane and LPG. This "light hydrocarbon route" not only has a more competitive cost, but its cracking process itself also has lower carbon emissions than traditional naphtha routes.

More importantly, all three machines of the ethylene plant (cracking gas compressor, propylene compressor, and ethylene compressor) are equipped with electric drive, greatly improving the electrification level of the project. This design has cleared the obstacles for large-scale coupled green power applications in the future, and is expected to significantly reduce the carbon dioxide emission intensity per unit product, creating a new sample for the green and low-carbon transformation of the refining industry.keywords:New energy latest reports

It is worth mentioning that the construction progress of the high-end polyolefin new material project under construction by Blue Ocean New Materials has reached 91.2%. The launch of the new project will form a synergistic effect with it, jointly consolidating PetroChina's competitive barriers in the field of high-end new materials.Editor/Yang Meiling
