As reported on January 16 by Daya Bay, the ethylene production project for Phase 3 in the Huizhou Daya Bay Petrochemical Zone, carried out by CNOOC Shell Huizhou, is in full swing, with a total completion rate of 42.49% so far. Upon completion of the project, CNOOC Shell’s ethylene production capacity will reach 3.8 million tons per year, allowing it to maintain its status as the largest single ethylene plant in China as well as the largest ethylene production base in terms of scale. The total investment for CNOOC Shell Huizhou Phase III ethylene project is approximately 48 billion yuan, covering the construction of an ethylene cracking plant with a capacity of 1.6 million tons per year, as well as 16 other chemical processing units, along with utility systems and supporting facilities. Upon completion of the project, CNOOC Shell’s ethylene production capacity will reach 3.8 million tons per year, allowing it to maintain its status as the largest single ethylene plant in China as well as the largest ethylene production base in terms of scale. CNOOC Shell Huizhou Phase III ethylene and polycarbonate projects represent another collaboration between China National Offshore Oil Corporation and Shell, building on the successful partnerships established in the Phase I and II projects of CNOOC Shell. The new project will be integrated with the existing resources from phases 1 and 2, as well as Huizhou Petrochemical’s refining industry, in order to improve the energy efficiency of integrated refining and chemical processing, effectively extend the product value chain, and deepen involvement in the field of high-end new materials, thereby meeting the needs of domestic customers for the further development of the petrochemical industry chain. This project introduces a number of process technologies that are used for the first time in Asia and within China. Seven of these units utilize Shell’s proprietary technologies, and together they are capable of supplying over 5 million tons of chemical products to the market each year. These products include metallocene polyethylene, polypropylene, styrene, polyether polyols, ethylene glycol, α-olefins, synthetic alcohols, and polyα-olefins. This will help fill the gap in demand for high-end chemical products in the domestic market, thereby facilitating the advancement of China’s petrochemical industry to higher positions in the global value chain. At the same time, through measures such as optimizing the project scope and electrifying large-scale compression units, Phase 3 of the project will achieve an overall 20% reduction in carbon dioxide emissions, promote the use of renewable green energy, and contribute to the implementation of the **\"Dual Carbon\" strategy. The construction includes a total of 16 chemical processing units for ethylene and its downstream products, namely: an ethylene cracking unit with a capacity of 1.6 million tons per year, a butadiene extraction unit with a capacity of 305,000 tons per year, a cracked gasoline hydrogenation unit with a capacity of 1.46 million tons per year, an aromatic extraction unit with a capacity of 1.1 million tons per year, an ethylene oxide-ethylene glycol (EO-EG) production unit with a capacity of 645,000 tons per year (including a unit for producing high-purity ethylene oxide with a capacity of 190,000 tons per year), a metallocene linear low-density polyethylene (mLLDPE) production unit with a capacity of 600,000 tons per year, a polypropylene (PP) production unit with a capacity of 500,000 tons per year, a linear α-olefin (LAO) production unit with a capacity of 400,000 tons per year, an isomerization and disproportionation (ID) unit with a capacity of 130,000 tons per year, a Shell hydroformylation (SHF) unit with a capacity of 130,000 tons per year, a polyα-olefin (PAO) production unit with a capacity of 50,000 tons per year, an ethylbenzene (EB) production unit with a capacity of 1 million tons per year, a styrene-propylene oxide (SM-PO) production unit with capacities of 875,000/400,000 tons per year respectively, a polyether polyol (DMC-POD) production unit with a capacity of 450,000 tons per year, a polymer polyol (POP-POD) production unit with a capacity of 100,000 tons per year, and an MTBE/butene-1 production unit with capacities of 270,000/80,000 tons per year.
