Abstract
This simulation experiment performed by Aspen Hysys is about theoretical investigation of gas sweetening performance of single amine solvents MEA1, MDEA2, DEA3, DGA4, DIPA5 and mixed amine solvents DGA-MEA, DEA-MDEA and SULFOLANE6-MDEA. Sweet gas having very high percentage of methane is produced by MEA (95.36%), DGA-MEA (95.37%), DEA-MDEA (95.51%) and SULFOLANE-MDEA (95.10%) and DGA (93.76%) shows lowest performance. DGA, SULFOLANE-MDEA, MDEA remove H2S at a lower circulation rate and DEA, DIPA need higher but satisfactory circulation rate. Increasing stage number shows positive effect on DEA, DIPA and SULFOLANE-MDEA. Pressure change has no significant effect. Temperature increase and methane percentage are negatively correlated for all solvents (except low circulating DIPA). With temperature increase H2S composition increases for DEA-MDEA, DGA-MEA; CO2 increases for DEA-MDEA, DGA-MEA and high circulating SULFOLANE-MDEA.
