石油化學工業(Petrochemical Industry)是以石油和天然氣為原料,通過裂解、重整、聚合等工藝生産基礎化學品及衍生材料的産業體系。其核心是将烴類化合物轉化為烯烴(如乙烯、丙烯)、芳烴(如苯、甲苯)等基礎化工原料,再進一步加工成塑料、合成纖維、橡膠、化肥等終端産品。該産業是現代化工體系的基礎支撐部門,直接影響農業、制造業、醫藥等領域的生産活動。
從原料構成來看,石油化工約70%的原料來自原油精煉産生的石腦油、液化氣等副産品,30%來自天然氣分離的乙烷、丙烷等組分(國際能源署2023年行業報告)。典型生産工藝中,蒸汽裂解裝置将原料在800-900℃高溫下分解,每生産1噸乙烯需消耗3噸石腦油,同時聯産丙烯、丁二烯等副産品。
主要産品鍊包含三條分支:①聚乙烯/聚丙烯等通用塑料,用于包裝材料和日用品制造;②對二甲苯(PX)-精對苯二甲酸(PTA)-聚酯産業鍊,支撐紡織業發展;③合成橡膠及特種化學品,服務于汽車制造和電子産業。根據美國化學理事會數據,全球每年約60%的合成材料産自石油化工體系。
該産業具有顯著規模效應,單個乙烯裂解裝置投資規模可達50億美元,年産能通常超過100萬噸。中國作為全球最大生産國,2024年乙烯總産能突破5000萬噸/年,主要生産基地分布在長三角、珠三角等石化産業園區(中國石油和化學工業聯合會年度報告)。技術創新方面,生物基原料替代和碳捕集技術正在推動行業向綠色低碳方向轉型。
petrochemical industry(石化工業)指以石油和天然氣為原料,通過化學加工生産各類化學品和合成材料的工業部門。以下是詳細解釋:
