Abstract

A thermodynamic model of Aspen Plus was developed for studying a novel direct steam stripping system based on detailed experimental tests, of which the simulation results were compared with relevant experimental data. Results show that the simulation results are in good agreement with relevant experimental data. The CO₂ regeneration energy obtained by simulation is 2.44 MJ/kg, lower than the experimental data 3.05 MJ/kg, which could be reduced to get near to the simulation results by modifying the stripper structure and promoting the mass transfer, and could be further reduced to 2.24 MJ/kg by reducing the temperature pinch of the economizer to 5 K.
