Abstract: Based on SINOALKY sulfuric acid alkylation process, a 20-lump reaction kinetics model and a reactor model were established. On the basis, an alkylation reactor module conforming to CAPE-OPEN standard with six material interfaces, a numerical solver and a visual user interface were developed. The reactor module was loaded into Aspen Plus simulation software, and a full process model of a 0.2 Mt/a SINOALKY alkylation unit was built, the simulation effect by the model was good. Furthermore, the effects of reaction parameters on the composition and properties of alkylation products were investigated. The results showed that the model simulation values were in accordance with the actual alkylation process, and the full process model including the SINOALKY alkylation reactor module could give important reference for the simulation and optimization of SINOALKY alkylation unit.
