Abstract: In order to meet the needs of China phase-VI gasoline, a new alkylation unit is imperative. The new 0.20 Mt/a alkylation unit of SINOPEC Luoyang Company adopted the SINOALKY, a sulfuric acid alkylation technology, independently developed by SINOPEC. Industrial results confirmed that the technology has the advantages of simple process, easy maintenance of reactor, low acid consumption and good product quality. When the reaction temperature was 0 ℃, the octane number of alkylate was 97, acid consumption was 65 kg/t alkylate, while unit energy consumption was 4598 MJ/t . Since the start of the unit, the process parameters and the operation of the unit has been stable, it can produce more than 16 kt of alkylae per month, which fundamentally solves the problem of gasoline blending and creates economic benefits of nearly 10 million Yuan for the company per month.

Key words: sulfuric acid alkylation, static mixing, octane munber, energy consumption
