In this work, continuous carbon dioxide (CO2) absorption-desorption experiments under simulated flue gas conditions and techno-economic analysis of CO2 capture using a novel water-lean ionic liquid (IL) absorbent were comprehensively combined to evaluate the feasibility of industrial applications. Thermodynamic and kinetic properties of the absorbent such as heat capacity, thermal conductivity, and absorption rate were explored and a reliable thermodynamic model was conducted. Meanwhile, continuous absorption-desorption experiments were carried out using a laboratory-scale continuous flow system (LCFS) to optimize operational parameters and assess the absorbent stability. Under optimal conditions, the CO2 concentration in the purified gas can be reduced to 0.70%, and the capture efficiency was as high as 95.76%. After 650 hours of continuous experiments under simulated flue gas, the IL concentration in the absorbent remained essentially unchanged, showing excellent stability. Based on above experimental results, a process model was developed in ASPEN Plus and validated. The validated model was further scaled up to a commercial scale and a techno-economic analysis was performed to evaluate the energy consumption and cost. The regeneration energy consumption (Qreg) for the absorbent was 1.31 GJ tCO2-1, and the total cost of capture was 38.81 $ tCO2-1, indicating strong potential for industrial application. © 2025, The Authors.

Water-lean ionic liquid absorbents for energy-efficient CO2 capture from flue gas: Continuous experiments and techno-economic evaluation

引用

Chemical engineering Journal 2025年 515卷

In this work, continuous CO2 absorption–desorption experiments under simulated flue gas (CO2, N2, O2, SO2 and NO) conditions and techno-economic analysis of CO2 capture using a novel water-lean ionic liquid (IL) absorbent (80 wt% IL, 14 wt% sulfoxide and 6 wt% water) were comprehensively combined to evaluate the feasibility of industrial applications. Thermodynamic and kinetic properties of the absorbent such as heat capacity, thermal conductivity, and absorption rate were explored and a reliable thermodynamic model was conducted. Meanwhile, continuous absorption–desorption experiments were carried out using a laboratory-scale continuous flow system (LCFS) to optimize operational parameters and assess the absorbent stability. Under optimal conditions, the CO2 concentration in the purified gas can be reduced to 0.70 mol%, and the capture efficiency was as high as 95.76 %. After 650 h of continuous experiments under simulated flue gas, the IL concentration in the absorbent remained essentially unchanged, showing excellent stability. Based on above experimental results, a process model was developed in ASPEN Plus and validated. The validated model was further scaled up to a commercial scale and a techno-economic analysis was performed to evaluate the energy consumption and cost. The regeneration energy consumption (Qreg) for the absorbent was 1.31 GJ tCO2-1, and the total cost of capture was 38.81 $ tCO2-1, indicating strong potential for industrial application. © 2025 Elsevier B.V.

The project manager's role and influence on the project's overall outcome have fascinated many academicians, researchers, and practitioners. The project manager's leadership and human skills play a vital role in the project's outcome;therefore, it is imperative for these competencies to be identified, learned, and leadership styles to be adopted. This study aims to define the most relevant competencies to multidimensional project success and their interrelationship. The quantitative method was used by applying a survey to project managers and team members working in the public sector of Pakistan. The results suggest that a combination of emotional, managerial intelligence, and transformational leadership are stronger predictors of multidimensional public project success. This study has shown that management and leadership need to be integrated to achieve better results. Project managers need to combine soft and hard skills, leadership competencies, and management to engage with people and be effective in terms of processes, tasks, and objectives. © 1973-2011 IEEE.

The stronger coordination ability of mercury ions with organic ligands than the metal ions in metal organic framework(MOFs) provides an accessible way to separate mercury ions from solution using specific MOFs. In this study, a Co-based MOF(ZIF-67, Co(mIM)) was synthesized. It did not introduce specific functional groups, such as-SH and-NH, into its structure through complicated steps. It separate Hgfrom wastewater with a new strategy, which utilized the stronger coordination ability of Hgwith the nitrogen atom on the imidazole ring of the organic ligand than the Coions. Hgreplaced Conodes from ZIF-67 and formed a more stable precipitate with m IM. The experimental results showed that this new strategy was efficient. ZIF-67 exhibited Hgadsorption capacity of 1740 mg/g, much higher than the known MOFs sorbents. m IMs is the reaction center and ZIF-67 can improve its utilization. The sample color faded from purple to white due to the loss of cobalt ion. It is a great feature of ZIF-67 that allows users to judge whether the sorbent is deactivated intuitively. ZIF-67 can be sustainable recycled by adding organic ligands to the solution after treatment due to its simple synthesis method at room temperature. It’s a high-efficient and sustainable sorbent for Hgseparation from wastewater.
