Investment and Scale - The project has a total investment exceeding 30 billion yuan, establishing the largest million-ton ethylene facility in Southwest China, which signifies a critical shift from scale dependency to quality improvement in the petrochemical sector [3]. Technological Innovations - The project features several technological advancements, including the world's largest 200,000-ton diesel adsorption separation unit, which enhances raw material utilization efficiency by over 15% compared to traditional methods [22]. - It employs CNPC's proprietary technology for a 50,000-ton/year 1-hexene production unit, showcasing the company's capacity for independent technological development [10]. - The facility includes the first domestically designed and built 30000 cubic meter ethylene low-temperature tank, ensuring safe storage of ethylene at ultra-low temperatures [19]. Production and Environmental Impact - Upon full operation, the project is expected to reduce refined oil output by 3.49 million tons annually while increasing chemical product output by 3.06 million tons, addressing domestic supply gaps in functional rubber, high-end polyolefins, and advanced membrane materials [23]. - The project achieves 100% green electricity for its new power consumption, with energy consumption metrics for refining and ethylene units exceeding national benchmark standards, aligning with national green and low-carbon development goals [23]. Market and Economic Implications - The project is set to transform Guangxi's industrial landscape from basic chemicals to high-end chemical new materials, leveraging the Western Land-Sea New Corridor to expand market reach into Southwest China, South China, and ASEAN markets [23]. - It aims to create a trillion-yuan green chemical new materials industry cluster, stimulating downstream industries such as packaging, construction materials, and automotive sectors, fostering a "leading role and cluster development" industrial ecosystem [23].
