Zhong Guo Xin Wen Wang·2025-10-27 03:46Core Viewpoint - The successful commissioning of the 1.2 million tons/year ethylene unit by China Petroleum Guangxi Petrochemical Company marks a significant transition from a "fuel-type" refinery to a "chemical products and organic materials-type" integrated refining and chemical enterprise, accelerating the development of a new industrial ecosystem in the Southwest region [1][4]. Group 1: Project Overview - The ethylene unit, constructed by China National Petroleum Corporation, utilizes proprietary large-scale ethylene technology and is capable of producing 1.2 million tons of polymer-grade ethylene, 616,000 tons of polymer-grade propylene, 400,000 tons of hydrogenated gasoline, and 35,000 tons of styrene annually, along with over 20 types of chemical raw materials and products [3][4]. - The project, which began construction in July 2023, faced significant climatic challenges but achieved ground-breaking in 8 months and a "soil-less" construction goal in 3 months, setting a benchmark for engineering projects in China [3]. Group 2: Economic Impact - The commissioning of the unit is expected to reduce oil product output by 3.49 million tons annually while increasing chemical product output by 3.06 million tons, directly addressing domestic supply gaps in high-end membrane materials and pipe materials [3][4]. - The project aims to transform Guangxi's industrial landscape from basic chemicals to high-end chemical new materials, leveraging the Western Land-Sea New Corridor to serve the Southwest, South China, and ASEAN markets, ultimately contributing to the establishment of a trillion-level green chemical new materials industry cluster [4].
