烷基化工艺技术经济比较

摘要
烷基化油具有辛烷值高、蒸气压低、不含烯烃和芳烃以及燃烧清洁等优点。近年来国家不断出台更为严格的汽油质量标准,烷基化油成为汽油池中必要调合组分。本文介绍了国内外主要的烷基化技术,对硫酸法烷基化、离子液烷基化和固体酸烷基化的工艺特点、原料杂质要求及主要操作条件进行了分析对比,测算了不同技术生产烷基化油的成本,从投资、物耗、能耗、安全环保等方面进行优劣势分析,为技术选择提供借鉴与帮助。
Alkylated oil has advantages of high octane number,low steam pressure,no olefins and aromatics,and clean combustion.In recent years,more strict gasoline quality standards are issued by government,alkylated oil becomes the necessary harmonic component in the gasoline pool.In this paper,the characteristics as well as raw material impurity and operating conditions of alkylation processes of sulfuric acid,ionic liquid and solid acid were compared.The costs for producing alkylated oil by different technology were calculated.Analysis of advantages and disadvantages in terms of investment,material consumption,energy consumption,safety and environmental protection was conducted.The work can be used for technology selection.
