Simulation of CO_2 removal with aqueous sodium glycinate solutions in a pilot plant

摘要

In this paper, density, viscosity, surface tension and vapor pressure of aqueous sodium glycinate solutions of different mass fractions (0.1-0.5) at different temperatures (20-100 ℃) were simulated using Pro/II (version 6.01), a commercial process simulator, and compared with corresponding experimentally measured data. It was found that simulated data of physicochemical properties compared well with corresponding experimental data. We have also predicted concentration of CO_2 with each ideal stage in an absorber/stripper tower.
