Summary: This study investigates the phase behavior of phase separation solvents before and after CO2 absorption using a predictive model. The results reveal that the hydrophilicity of amines affects the molecular interactions and miscibility of the solvents. The study suggests that amines with balanced interactions with water and glycol ether are potential candidates for CO2 capture phase separation solvents.

Summary: In this work, the solid-liquid equilibrium (SLE) and vapor-liquid-liquid equilibrium (VLLE) of a cryogenic mixture of difluoromethane (R32) + octafluoropropane (R218) were studied. The experimental results showed that this binary mixture does not exhibit the common eutectic behavior, and the temperatures of the liquidus line remain constant at different mole fractions. The experimental VLLE data was analyzed using polynomial and rectilinear diameter methods, and both methods showed good agreement. Additionally, a solid-liquid-liquid equilibrium (SLLE) of R32 + R218 was inferred based on the experimental data, providing an explanation for the unusual experimental data in mixed refrigerants.

Summary: This study focuses on separating a mixture of 1,2-ethanediol, 1,3-propanediol, and 1,4-butanediol. Different activity coefficient models were used to fit the vapor-liquid equilibrium data, and then the NRTL model was used to design the separation process. The results showed that using a liquid-only transfer dividing wall column can reduce the total cost and energy consumption.

Summary: The Aquivion (R) E87-12S membrane material has shown promising separation performance for natural gas sweetening from CO2 and H2S due to its chemical and mechanical stability, especially in humid environments. The permeation behavior of the H2S/CO2/CH4 ternary mixture through this membrane was found to be dependent on water activity and temperature, with the membrane showing higher permeability to H2S compared to CO2 and CH4.

Summary: The compression-absorption cascade system (CACS) is a highly efficient method to utilize waste heat or renewable energy. However, most current studies focus on heating scenarios and the cooling characteristics of CACS have not been explored. Ionic liquids (ILs) show promise as alternative working fluids for absorption systems, but their high price hinders large-scale application. This study proposes a feasible strategy to overcome this economic constraint by using a relatively inexpensive salt to replace part of the costly IL as the absorbent. Experimental measurements of the vapor-liquid equilibrium data and analysis of the cooling performance of CACS using the proposed working pair, LiBr/[EMIM][OAC]/H2O, reveal that it outperforms traditional absorption chillers and other reference working fluids in terms of cooling efficiency and economic limitations.

Summary: Poor interfacial compatibility is a challenge in fabricating high-performance polymer-MOF composites. Introducing compatible chemistries, such as carboxylic acid, is a compelling strategy to enhance polymer-MOF interactions. By leveraging compatible functionalities in UiO-66-NH2 and carboxylic acid-functionalized PIM-1, mixed-matrix membranes (MMMs) with improved separation performance were successfully fabricated. The addition of UiO-66-NH2 in PIM-COOH and PIM-1 mitigated plasticization effects and enhanced interfacial compatibility, resulting in MMMs with high selectivity combinations under industrially relevant conditions.

Summary: A concentration-dependent surface area parameter model was modified to remove the restrictions on the parameters of pure components. This model successfully correlated ternary liquid-liquid equilibria and constituent binary phase equilibria using a single set of binary parameters. The correlated results outperformed those obtained by the NRTL and UNIQUAC models. Additionally, the model accurately represented experimental data for both liquid-liquid and vapor-liquid equilibria at multiple temperatures using a single parameter set.

Summary: Compositional control in III-V ternary nanowires grown through the vapor-liquid-solid method is crucial for bandgap engineering and the design of functional nanowire nano-heterostructures. The vapor-solid distribution of these nanowires is found to be kinetically controlled, while the liquid-solid distribution is in equilibrium or nucleation-limited. The developed approach, which eliminates unknown parameters and circumvents uncertainty in choosing the relevant compositional model, allows for precise compositional tuning of these nanowires.

Summary: The primary objective of this study is to develop an empirical correlation model to predict the solid-liquid-vapor phase equilibria (SLVE) for the ternary system of N-2-Kr-Xe, using the Peng-Robinson equation of state. The model is optimized by correlating experimental data from literature for the binary systems N-2-Kr, N-2-Xe, and Kr-Xe, and then expanded to predict the SLVE and construct the phase envelope of the ternary system.
