Modelling VLE data of CO2 and H2S in aqueous solutions of N-methyldiethanolamine based on non-random mixing rules

- We simulated the VLE data of CO2 and H2S in MDEA solutions with two parameter EOS.
- Random mixing rules have not worked well for this simulation.
- Adding binary interaction parameters (kij) gives more deviations from experimental data.
- Non-random mixing rules are well-suited for the modelling of these systems.
- We compared our modelling results to results of e-NRTL, ePC-SAFT and UNIQUAC models.
