Review of carbon capture absorbents for CO₂utilization

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. Carbon capture and storage (CCS) is preferred over carbon conversion and utilization (CCU) due to its lower operating costs and higher CO2 reduction capability. Nevertheless, CO2 utilization has the potential to be more economical if value‐added products are produced. This highlights the importance of assessing CO2 utilization routes and alternatives in carbon management. This review paper aims to evaluate the carbon utilization potential of major CO2‐capturing absorbents including amine, hydroxide, ionic liquid, amino acids and carbonate absorbents. All absorbents show potential application for CO2 utilization except for ionic liquids (ILs) due to their unclear CO2 capture mechanisms. Absorbents that require a desorption process for CO2 utilization include MEA, MDEA, K2CO3 and Na2CO3 due to their high absorption capacity. Industries have utilized the desorbed CO2 as chemical feedstocks, enhanced oil recovery (EOR) and mineral carbonation. For hydroxide absorbents and CaCO3, desorption of CO2 is unnecessary as the absorbed CO2 can be directly utilized to produce construction materials. Apart from that, the incorporation of advanced technologies and business models introduced by the fourth industrial revolution are plausible considerations to accelerate the development of carbon capture technologies. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Fugacity affects both the direction of diffusion and the rate of diffusion. − Net transfer continues from regions of higher fugacity to regions of lower fugacity until a condition of equal fugacity, or equilibrium, is achieved. The concept of fugacity has long been used in the field of chemical engineering in designing processes such as distillation, gas absorption, solvent extraction, etc. − The importance of fugacity as an index of toxicity was later discussed by Ferguson . Mackay expanded on the concept of fugacity in mass transfer models in environmental exposure studies.…”

Transdermal uptake models compliment in vitro and in vivo experiments in assessing risk of environmental exposures to semi-volatile organic compounds (SVOCs). A key parameter for mechanistic models is a chemical driving force for mass transfer from environmental media to human skin. In this research, we measure this driving force in the form of fugacity for chemicals in cosmetic cream and use it to model uptake from cosmetics as a surrogate for condensed environmental media. A simple cosmetic cream, containing no target analytes, was mixed with diethylphthalate (DEP), di-n-butylphthalate (DnBP), and butyl paraben (BP) and diluted to make creams with concentrations ranging from 0.025% to 6%. The fugacity, relative to the pure compound, was measured using solid-phase micro extraction (SPME). We found that the relationship between the concentration and fugacity is highly non-linear. The relative fugacity of Page 1 of 43 ACS Paragon Plus Environment Environmental Science & Technology 2 the chemicals for a 2% w/w formulation was used in a diffusion-based model to predict transdermal uptake of each chemical and compared with excretion data from a prior human subject study with the same formulation. Dynamic simulations of excretion are generally consistent with the results of the human subject experiment but sensitive to the input parameters, especially the time between cream application and showering.
