Abstract

In this study, solubility of carbon dioxide (C02) in new aqueous blends of diethanolarnine (DEA) + 2-amino-2-hydroxymethyl-1, 3-propanediol (AHPD) was carried out at temperatures of (303 K and 333 K) and C02 partial pressure ranging from (I 00 - 2000 kPa). The total aqueous blends amine mass fraction was kept within 30 wt% in all solutions, varies at (30 wt"/o DEA + 0 wt% AHPD), (20 wt% DEA + 10 wt% AHPD), (10 wt% DEA + 20 wt% AHPD) and (0 wt"lo DEA + 30 wt% AHPD). The results show higher C02 loading capacity is achieved when the system is operated at lower temperature and at higher C02 partial pressure. At a fixed temperature, an increase in mass fraction of AHPD in the aqueous blends solution leads to higher COz loading capacity. C02 loading capacity was found highest in the blends of I 0 wt% DEA + 20 wt% AHPD at 1680 kPa and 303 K, which is 1.2814 mol of C02/ mol of absorbent. Physical properties such as density and viscosity ofDEA + AHPD are also measured at temperature of (303 K- 333 K).
