Absorption rates of carbon dioxide and hydrogen sulphide in sterically hindered amines

Thermal effects of CO2 absorption in aqueous solutions of 2‐amino‐2‐methyl‐1‐propanol

“…These results partially coincide with those of Sartori et al 15 and Zioudas and Dadach. 23 These latter authors detected, when using pure CO 2 and a concentration of 0.05 kmol/m 3 , that the absorption rate in AMP was 25% higher than when aqueous MEA solutions were used in experiments conducted at 297 K. Similar comparisons to those in Figure 5 resulted for the other temperatures assayed in the absorption processes with AMP.…”

Reaction mechanism and kinetics of aqueous solutions of 2-amino-2-methyl-1-propanol and carbon dioxide

“…In the case of AMP, a number of heterogeneous gas absorption studies were carried out previously. Sharma (1965) reported a second-order rate constant of 1048 m3/(kmobs) at 298 K. Sartori et al (1987) and Chakraborty et al (1986) deduced a rate constant of about 100 m3/(kmol's) at 313 K. The recent study by Yih and Shen (1988) reports a rate constant of 1270 m3/(kmol-s) at 313 K. Absorption rates of C02 and H2S (but not direct kinetic data) were also reported for AMP by Zioudas and Dadach (1986). These gas absorption studies were all analyzed by 0888-5885/90/ 2629-1725$02.50/ 0 which subsequently hydrolyzed.…”

Simulation of the Effects of Turbine Exhaust Recirculation on the Composition of Flue Gas for A CO2 Capture Unit

“…Unlike Pre-combustion and Oxy fuel strategies, Post-combustion CO 2 Capture can be integrated with the existing power generation stations. At the moment, the post-combustion CO 2 capture using amine scrubbing is the most mature technology, and arguably the preferred technology, since the process of absorption has been used for decades in gas treatments [4,5]. The existing size of commercial CO 2 amine scrubbing plants is relatively small (few 100,000 metric tons/year).…”
