图为装置现场。(企业供图) 中化新网讯 10月26日，中国石油广西石化公司(以下简称广西石化)120万吨/年乙烯装置正式投料，于10 月27日凌晨产出合格产品，标志着该装置一次开车成功，将推动形成西南地区"龙头带动、集群发展"的 石化产业新生态。 广西石化相关负责人表示，这一关键节点标志着该公司彻底完成从"燃料型"炼厂向"化工产品及有机材 料型"炼化一体化企业的根本性跨越，也为西南地区石化产业形成"龙头带动、集群发展"的产业新生态 升级按下"加速键"。 据介绍，该装置由寰球工程有限公司总承包，采用中国石油自主知识产权的大型乙烯成套工艺技术，每 年可生产聚合级乙烯120万吨、聚合级丙烯61.6万吨、加氢汽油40万吨、苯乙烯3.5万吨，并副产氢气、 裂解碳五、碳九及裂解燃油等20多种化工原料、产品和半成品。该装置投产后，可推动广西石化每年减 少油品产量349万吨、增产化工品306万吨，其中高端膜料、管材料等产品将直接填补国内供给缺口，缓 解我国石化产业"油多化少、高端不足"的结构性矛盾。 ...

Core 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].

Core Viewpoint - Jilin Petrochemical's new 1.2 million tons/year ethylene plant has successfully produced qualified ethylene products, increasing its total ethylene capacity to 1.9 million tons/year [1] Investment and Capacity - The total investment for the new ethylene facility is 4.177 billion yuan (including tax), covering an area of 119,000 square meters [1] - The new plant is expected to produce 1.2 million tons of polymer-grade ethylene and 587,000 tons of polymer-grade propylene annually, along with over 20 types of chemical raw materials and products [1] Technology and Equipment - The plant utilizes domestic CBL cracking technology and LECT separation technology, achieving a domestic equipment localization rate of 96% [1] - Key core equipment has achieved 100% independent control, with comprehensive energy consumption and other technical indicators reaching advanced domestic levels [1] Project Timeline - The foundation work for the facility began on November 12, 2022, with civil construction starting on April 1, 2023 [1] - Mechanical completion is scheduled for November 30, 2024, with intermediate handover on April 30, 2025, and successful initial operation on August 31, 2025 [1]
