MODELING AND FULL PROCESS SIMULATION OF SULFURIC ACID ALKYLATION REACTOR BASED ON CAPE-OPEN STANDARD

Abstract

Abstract: Based on the mechanism model of sulfuric acid alkylation established by Stratco process of the DuPont company, the unit operation module of sulfuric acid alkylation reactor was developed by using C++ and COM technology, which conformed to CAPE-OPEN standard, the model could interact with the general chemical process simulation software through unit operation interface and the thermodynamic physical property interface, and a convenient and friendly user interface was established. The module of sulphuric acid alkylation reactor was embedded in Aspen Plus, and the whole process simulation of the sulfuric acid alkylation process could be realized by means of Aspen Plus's physical property data, thermodynamic method and conventional unit operation module of the simulation software itself. The simulation results are in good agreement with the actual industrial data, which shows that the CAPE-OPEN sulfuric acid alkylation reactor module is stable and reliable, it will plays an important role in the process simulation and parameter optimization of the sulfuric acid alkylation unit.

Key words: sulfuric acid alkylation process, mechanism model, Stratco reactor, CAPE-OPEN, process simulation
