摘要
介绍在油价高企时期烷基化装置的重要性以及国内外烷基化油的生产情况,分析了烷基化装置在国内发展不足的原因;介绍烷基化技术的历史沿革以及以清洁生产为主线的国内外最新技术进展;针对目前烷基化装置的经济效益问题,以240 kt/a烷基化装置为例,依据中石化技术经济评价方法,烷基化油作为汽油调合组分,计算得出烷基化油价格与原料液化石油气价差为2 981 RMB$/t(含税)时,项目的税后财务内部收益率可达到基准值13%,若扣除消费税因素的影响,价差只需1 357 RMB$/t(含税)即可达到内部收益率基准值;指出在液化石油气充足地区,以液化石油气为原料生产烷基化油,具有一定的经济效益,同时随着天然气在民用燃料领域的广泛使用,液化石油气与汽油的差价将不断扩大,烷基化装置的发展将有更大的空间。
The importance of alkylation unit at the time of high crude oil price and production of alkylation units both in China and abroad are introduced. The development of alkylation units and insufficient instal- lation in China are analyzed. The history of alkylation process and latest development of technologies for producing clean fuel are described. In a case study of a 240,000 TPY alkylation unit, the financial internal rate of return （FIRR） reaches benchmark 13% when the alkylate is used as gasoline blending component and price difference between alkylate and LPG feed is 2 981 Yuan RMB/t （ including tax） based upon the technoeconomic assessment method of SINOPEC. When the consumer tax is deducted, the benchmark value of FIRR can be reached at a price difference of 1 357 Yuan RMB （including tax）. In the areas with sufficient LPG supply, it is economic to produce alkylate from LPG feed. With increased utilization of natural gas as civilian fuel, the price difference between LPG and gasoline will become increasingly greater. There will be a greater room for the development of alkylation units.
