“…The PCC method can be applied wherever flue gases are emitted from their source, and CO 2 can be separated at regular atmospheric pressure and moderate temperature ranges. Technologies such as flue-gas desulfurization, selective catalytic reduction, and electrostatic precipitation can be utilized to eliminate CO 2 and other compounds present in flue gas, including N 2 , CO 2 , H 2 O, O 2 , as well as sulfur oxides, nitric oxides, and heavy metals [69][70][71][72]. The typical methods utilized for PCC include calcium looping, cryogenic separation, chemical absorption, physical adsorption, and membrane separation.…”

“…Sorbents play crucial roles in these methods, and they can be categorized into solid sorbents and liquid sorbents. Since CO 2 is classified as an acid gas (Lewis acid), most sorbents, whether in solid or liquid form, are treated to exhibit basic properties, thereby facilitating the sorption process [69]. In the case of liquid sorbents, high temperatures are essential to pass heated air through a chemical solution, extracting carbon in a liquid state and releasing the remaining components back into the air.…”

The synthesis of graphene through environmentally friendly and efficient methods has posed a persistent challenge, prompting extensive research in recent years to access sustainable source and attain high quality graphene competing with the one obtained from graphite ores. Addressing this challenge becomes even more intricate when aiming to convert captured CO2 into graphene structures, encountering hurdles stemming from the inherent stability of the CO2 molecule and its steadfast transformation. Together with CO2, there is a great potential to create carbon source by using natural biomass, cellulosic plant sources and industrial wastes. This comprehensive review delves into the recent synthesis techniques and developments, exploring both direct and indirect pathways for the integration of CO2 that strive to overcome the complexities associated with transforming CO2 into graphene. The review critically analyzes CO2 capturing mechanisms designed for air, ocean, and alternative sources, outlining the progress made in harnessing captured CO2 as a feedstock for graphene production by evaluating captured CO2 values. This review consolidates the recent advancements by providing a roadmap for future research directions in the sustainable synthesis of graphene from captured CO2 in the pursuit of a greener, circular economy.

“…Viola et al [20] studied the CO 2 capture on silica impregnated with amine. However, the regeneration of CO-rich amine solutions is cost-intensive due to energy consumption, accounting for approximately 70% of the cost of operation [21,22]. Addressing the cost remains a crucial challenge that requires further research and development.…”

In the realm of Natural Gas Combined Cycle (NGCC) power plants, it is crucial to prioritize the mitigation of CO2 emissions to ensure environmental sustainability. The integration of post-combustion carbon capture technologies plays a pivotal role in mitigating greenhouse gas emissions enhancing the NGCC’s environmental profile by minimizing its carbon footprint. This research paper presents a comprehensive investigation into the integration of solar thermal energy into the Besmaya Natural Gas Combined Cycle (NGCC) power plant, located in Baghdad, Iraq. Leveraging advanced process simulation and modeling techniques employing Aspen Plus software, the study aims to evaluate the performance and feasibility of augmenting the existing NGCC facility with solar assistance for post-carbon capture. The primary objective of this research is to conduct a thorough simulation of the Besmaya NGCC power plant under its current operational conditions, thereby establishing a baseline for subsequent analyses. Subsequently, a solar-assisted post-combustion capture (PCC) plant is simulated and seamlessly integrated into the existing power infrastructure. To accurately estimate solar thermal power potential at the Baghdad coordinates, the System Advisor Model (SAM) is employed. The integration of solar thermal energy into the NGCC power plant is meticulously examined, and the resulting hybrid system’s technical viability and performance metrics are rigorously evaluated. The paper contributes to the field by providing valuable insights into the technical feasibility and potential benefits of incorporating solar thermal energy into conventional natural gas power generation infrastructure, particularly in the context of the Besmaya NGCC plant in Baghdad. The power generation capacity of the plant was set at 750 MW. With this capacity, the annual CO2 generation was estimated at 2,119,318 tonnes/year which was reduced to 18,064 tonnes/year (a 99% reduction). The findings aim to inform future decisions in the pursuit of sustainable and efficient energy solutions, addressing both environmental concerns and energy security in the region.

In the pursuit of mitigating CO2 emissions, this study investigates the optimization of CO2 purification within a negative CO2 emission power plant using a spray ejector condenser (SEC) coupled with a separator. The approach involves direct‐contact condensation of vapor, primarily composed of an inert gas (CO2), facilitated by a subcooled liquid spray. A comprehensive analysis is presented, employing a numerical model to simulate a cyclone separator under various SEC outlet conditions. Methodologically, the simulation, conducted in Fluent, encompasses three‐dimensional, transient, and turbulent characteristics using the Reynolds stress model turbulent model and mixture model to replicate the turbulent two‐phase flow within a gas–liquid separator. Structural considerations are delved into, evaluating the efficacy of single‐ and dual‐inlet separators to enhance CO2 purification efficiency. The study reveals significant insights into the optimization process, highlighting a notable enhancement in separation efficiency within the dual‐inlet cyclone, compared to its single inlet counterpart. Specifically, a 90.7 % separation efficiency is observed in the former, characterized by symmetrical flow patterns devoid of wavering CO2 cores, whereas the latter exhibits less desirable velocity vectors. Furthermore, the investigation explores the influence of key parameters, such as liquid volume fraction (LVF) and water droplet diameter, on separation efficiency. It is ascertained that a 10 % LVF with a water droplet diameter of 10 µm yields the highest separation efficiency at 90.7 %, whereas a 20 % LVF with a water droplet diameter of 1 µm results in a reduced efficiency of 50.79 %. Moreover, the impact of structural modifications, such as the addition of vanes, on separation efficiency and pressure drop is explored. Remarkably, the incorporation of vanes leads to a 9.2 % improvement in separation efficiency and a 16.8 % reduction in pressure drop at a 10 % LVF. The findings underscore the significance of structural considerations and parameter optimization in advancing CO2 capture technologies, with implications for sustainable energy production and environmental conservation.
