“…Following this suggestion, numerous investigations were devoted for the measurement of CO 2 solubility in MDEA-based solvents. A comprehensive set of data on CO 2 equilibrium solubility in MDEA-DEA and MDEA-MEA systems under various operating conditions can be found in the open literature [3][4][5][6][7].…”

Solubilities of CO 2 in aqueous solutions of activated methyldiethanolamine (MDEA) has been investigated for temperatures and CO 2 partial pressures ranging from 40 to 80 • C and 0.1 to 100 kPa, respectively. Piperazine (PZ) is used as activator, with a concentration ranging from 0.01 to 0.1 M, keeping the amine total concentration in the aqueous solution at 2 M. The experimental solubility results were represented by the mole ratio of CO 2 per activated amine present in the liquid mixture. The addition of piperazine, as activator for MDEA, increased the solubility of CO 2 in the region of low CO 2 partial pressure compared to pure MDEA. The CO 2 loading increased with decreasing temperature, increasing CO 2 partial pressure, and increasing PZ concentration.

“…The enthalpy of solution can be derived from solubility measurements by using the Gibbs-Helmholtz equation. Enthalpy of solution values have been derived from solubility data for carbon dioxide in aqueous monoethanolamine by Jou et al, (2) carbon dioxide in aqueous diethanolamine by Lee et al (3) and carbon dioxide in aqueous N -methyldiethanolamine by Jou et al (4) The enthalpy of solution of both carbon dioxide and hydrogen sulfide has been measured in aqueous diethanolamine at T = (298.15 K, 323.15 K, and 348.15 K) by Kahrim (5) using an isoperibol calorimeter. At Brigham Young University measurements have been made using isothermal flow calorimetry of carbon dioxide in aqueous 2-[2-aminoethoxy]ethanol (diglycolamine), (6) aqueous diethanolamine (6) and aqueous Nmethyldiethanolamine.…”

“…Commercially available amine absorbents have been broadly investigated by a number of researchers [4][5][6][7][8][9][10][11]. A new class of amines referred to as sterically hindered amines, such as 2-amino-2-methyl-1-propanol (AMP) and 2-Piperidineethanol (2-PPE), have been proposed as commercially attractive new solvents for treating acid gas and to replace existing commercial amines such as monoethanolamine (MEA), diethanolamine (DEA), 2-(ethylamino)ethanol, (EAE), and N-methyldiethanolamine (MDEA) [6,12].…”

COURSE50 (ultimate reduction of CO 2 in the steelmaking process through innovative technology for Cool Earth 50) aims to capture, separate, and recover CO 2 from blast furnace gas. From a practical realization viewpoint, three points are important. The first is energy consumption to regenerate the absorbent, second is the energy cost of the heat for regeneration, and third is the facility cost. The advantage afforded by the COURSE50 approach in relation to the CO 2 capture process is the utilization of unused waste heat from the steel mills. Energy consumption to regenerate the absorbent is determined mainly by three factors: the regeneration reaction determined primarily by the structure of the chemical absorbent, the energy required to heat that volume of absorption liquid, which is affected by the absorption rate of the agent, and the heat loss from the processes. The most influential factor is the energy required for the regeneration reaction. We discovered high-performance absorbents with the advantages of high absorption rates, high cyclic capacities, and low heats of reaction, and we then compared these with monoethanolamine (MEA) and N-methyldiethanolamine (MDEA). The newly discovered absorbents performed well in terms of absorption rates and cyclic capacities. Among these absorbents, some showed lower heats of reaction than MDEA. These results provide a basic guideline for the discovery of potential amine-based absorbents that may lead to the development of new absorbent systems for CO 2 capture.Keywords CO 2 emissions mitigation Á Steelworks Á Separation and recovery of CO 2 from blast furnace gas Á Unused exhaust heat in steelworks Preface OverviewWe have executed technology development through an innovative R&D program, the COURSE50 project [1,2]. This project, which commenced in fiscal 2008, aims to mitigate CO 2 emissions from integrated steel plants. Figure 1 presents an outline of the COURSE50 project and the two major areas of research.One area is the development of technology to reduce CO 2 emissions from blast furnaces, involving (1) reaction control technology to reduce iron ore by using hydrogen, (2) reforming technology for coke oven gas (COG) that increases the amount of hydrogen produce, and (3) technology to manufacture high-strength and high-reactivity coke for hydrogen-reduction blast furnaces.The other area is the development of technology to capture CO 2 from blast furnace gas (BFG) through chemical absorption and physical adsorption methods using unused waste heat in the steelworks. The final objective is
