摘　　要：近年来,为满足国六汽油升级要求,炼油厂纷纷投产烷基化装置生产烷基化油,而大部分烷基化装置采用硫酸法工艺,生产过程中产生大量废酸,因而配套建设废酸再生装置解决废酸处置和新酸供应问题。废酸再生主要分干法和湿法两种工艺,本文主要介绍奥地利P&P公司湿法硫酸再生工艺的应用情况。In recent years, in order to meet the upgrading requirements of national sixth gasoline, refineries have put into operation alkylation units to produce alkylated oil one after another. Most of the alkylation units adopt sulfuric acid process, which generates a large amount of waste acid in the production process. Therefore, waste acid regeneration units are built to solve the problems of waste acid disposal and new acid supply. Waste acid regeneration is mainly divided into dry process and wet process. This paper mainly introduces the application of wet sulfuric acid regeneration process of P & P company in Austria.
