Abstract:
The extractive distillation section of Butadiene unit has been simulated in steady-state conditions. It is mainly consists of three important interconnected columns so that their simulation should be done simultaneously. Simulation of columns carried out in two modes as programming in Matlab-7.5 and using Aspen-plus software. Equilibrium stage model and SRK equation of state were used in Matlab. The systems of equations including Mass balance, Equilibrium, Summation and Energy balance (MESH) were solved simultaneously by quasi-Newtonian Broyden-Householder method. Radfrac model and PSRK equation of state were used in Aspen-plus software. Simulation results for temperature, pressure, and composition of fifteen considered components were determined. The comparison between simulated results and industrial data extracted from Tabriz petrochemical complex shows good agreement.
