“…Since the concept of CCS was developed, solvent based CO 2 capture technologies have undergone constant development to meet the challenge of controlling CO 2 emissions [132][133][134] from large point sources. Over this period industry has gained excellent experience and sufficient confidence to commercialise solvent based carbon capture technologies both in pre-and post-combustion processes.…”

Currently, a large proportion of global fossil fuel emissions originate from large point sources such as power generation or industrial processes. This trend is expected to continue until the year 2030 and beyond. Carbon capture and storage (CCS), a straightforward and effective carbon reduction approach, will play a significant role in reducing emissions from these sources into the future if atmospheric carbon dioxide (CO 2 ) emissions are to be stabilized and global warming limited below a threshold of 2°C. This review provides an update on the status of large scale integrated CCS technologies using solvent absorption for CO 2 capture and provides an insight into the development of new solvents, including advanced amine solvents, amino acid salts, carbonate systems, aqueous ammonia, immiscible liquids and ionic liquids. These proposed new solvents aim to reduce the overall cost CO 2 capture by improving the CO 2 absorption rate, CO 2 capture capacity, thereby reducing equipment size and decreasing the energy required for solvent regeneration.

“…Though these numbers come from simulations containing only a single gas, the mixed gas systems tried gave comparable values, though no numbers were given for the full ternary system. There are a few papers 44,45 that 14 suggest the use of ionic liquids, but there is no evidence that this method of sweetening has been implemented commercially. Primary and secondary amines, like MEA and DEA respectively, can react directly with the acid gas components.…”

AbstractFossil fuels are still a necessary and important part of modern living, keeping cars running and houses heated for example. As demands have risen and reservoirs of oil and natural gas have depleted, it has become increasingly more important to tap in to fields that were once classified as undesirable. Sour fields, fields high in acidic gases such as hydrogen sulfide and carbon dioxide, are one such option. There are many difficulties and dangers associated with working sour fields, such as toxicity of the sour gases, hydrate formation and corrosion of equipment that have prevented these resources being used in the past. Many varied methods of overcoming these problems have been developed, from removing the sour components to inhibiting their effects. This review highlights the major issues raised by sour fields as well as a wide range of solutions in use today.

“…[6][7][8] In recent years, ionic liquids (ILs), with features of non-volatility, thermal stability, and tuneable properties, 9 were proposed as the favoured options to overcome some of the problems with amines. [10][11][12] In addition, it is also inevitable to develop more versatile alternatives with respect to the price and environmental benignness. [13][14][15] Research effects have been directed toward polymeric surfactants owing to their potential applications in many fields.…”

1-allyloxy-3-(4-nonylphenoxy)-2-propanol polyoxyethylene ethers (ANAPEs), a new type of absorbent, are polymeric surfactants with different adduct numbers. In this work, ANAPEs, including SN-10 with adduct number of 10 and SN-15 with adduct number of 15, were prepared for CO 2 absorption using the isochoric saturation method. Densities of the ANAPEs at atmospheric pressure were measured by a 5.567 ± 0.004 cm 3 pycnometer, which decreased with increased temperature. Solubility data of CO 2 in ANAPEs were measured within the pressure range of 0 - 600.0 kPa and temperature range of 303.15 - 323.15 K at 10 K intervals and could be calculated on the basis of experimental data of p, x CO2 and b CO2 . The solubility of CO 2 in absorbents increased linearly with increasing pressure and decreased with increasing temperature at all the pressures. The solubility of CO 2 in SN-15 is the highest at all temperatures, but almost the same with SN-10 at 303.15 K over pressures (p < 350kPa), which indicates physical dissolution process. Henry's constants were determined from solubility data. With increasing temperature, Henry's constants increased. Thermodynamics of CO 2 absorption were calculated including enthalpy, entropy, and Gibbs energy. The absolute value of Δ sol H based on H x of SN-15 is largest at 303.15 K and indicates stronger SN-15/CO 2 interactions, consistent with solubility of CO 2 based on H x . The negative enthalpy demonstrated exothermic process, which means the dissolution of CO 2 in ANAPEs is favourable enthalpically. The Δ sol G shows positive value.
