PETROCHINA(SH:601857) Zhong Guo Hua Gong Bao·2025-10-28 03:21Core Viewpoint - The successful commissioning of the 1.2 million tons per year ethylene unit at Guangxi Petrochemical marks a significant transition from a fuel-based refinery to a comprehensive refining and chemical enterprise, enhancing the petrochemical industry ecosystem in Southwest China [1][4]. Group 1: Production Capacity and Technology - The ethylene unit, contracted by Huanyu Engineering Co., Ltd., utilizes proprietary technology from China National Petroleum Corporation, 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 [4]. - The unit will also produce over 20 types of chemical raw materials, products, and semi-finished products, including hydrogen, cracked C5, C9, and cracked fuel oil [4]. Group 2: Impact on Industry and Supply - The commissioning of the unit is expected to reduce oil product output by 3.49 million tons and increase chemical product output by 3.06 million tons annually, addressing the domestic supply gap for high-end materials such as membrane and pipe materials [4]. - This development aims to alleviate the structural contradiction in China's petrochemical industry characterized by an excess of oil products and a shortage of high-end chemical products [4].
