One hundred and ten Qilu Petrochemical Industry 1995 STRA TCO sulfuric acid alkylation process Technical characteristics and influencing factors analysis Lijianlun (Qilu Petrochemical Industries Co Shengli Refinery, Zibo, 255434) Abstract this paper introduces the technical characteristics of STRA TCO nitric acid alkylation unit of Shengli Refinery introduction, and analysis the influence factors of sulfuric acid alkylation reaction and controlling the best operating conditions and reduce the acid consumption, improve product quality and yield and the way. 1 Preface The energy also allows the acid and hydrocarbon to have a greater contact interface, and olefins in the feed can be rapidly dispersed in the yogurt solution. These structural characteristics of the reactor are favorable to improve the yield and quality of the alkylated oil. For a circular emulsion is a core part of the STRA TCO settlement horizontal eccentric reactor and high acid, compared with acid circulation pump, improve the reaction conditions. Fresh acid acid into the circulating pipe with olefin recycle acid and mixed with refrigerant feed into each reactor in the impeller at the entrance, the entrance nozzle was immediately with the rotation of the impeller suction acid hydrocarbon emulsive state, and quickly leave the impeller. At this point, the reaction material and catalyst (H 2, SO 4) are strongly cut and stirred by the nozzle and impeller, and are fully mixed at the entrance of the reactor to accelerate the alkylation reaction and produce alkylated oil. The reaction product (including iC 0) enters the acid settler through an upward tube and is separated by 4 acid hydroc
