“…CO 2 capture and sequestration (CCS) could reduce greenhouse gas emissions and enable low-carbon electricity generation from power plants [1]. In order to reduce the overall cost and increase the possibility of practical application of CCS, solid adsorption becomes a competitive and viable method for CO 2 removal, and most of the researches focus on the development of adsorbents with high CO 2 capacity and efficiency [2][3][4][5].…”

Tetraethylenepentamine (TEPA)-based mesoporous MCM-41 is used as the adsorbent to determine the CO 2 desorption kinetics of amine-modified materials after adsorption. The experimental data of CO 2 desorption as a function of time are derived by zero-length column at different temperatures (35, 50, and 70 • C) and analyzed by Avrami's fractional-order kinetic model. A new method is used to distinguish the physical desorption and chemical desorption performance of surface-modified mesoporous MCM-41. The activation energy E a of CO 2 physical desorption and chemical desorption calculated from Arrhenius equation are 15.86 kJ/mol and 57.15 kJ/mol, respectively. Furthermore, intraparticle diffusion and Boyd's film models are selected to investigate the mechanism of CO 2 desorption from MCM-41 and surface-modified MCM-41. For MCM-41, there are three rate-limiting steps during the desorption process. Film diffusion is more prominent for the CO 2 desorption rates at low temperatures, and pore diffusion mainly governs the rate-limiting process under higher temperatures. Besides the surface reaction, the desorption process contains four rate-limiting steps on surface-modified MCM-41.

“…The cryogenic separation method for CO 2 capture is mainly based on the principle of condensation and cooling [106][107][108][109][110]. It is mostly applied in CO 2 capture systems where the gas streams contain a high concentration of CO 2 .…”

Abstract:The global atmospheric concentration of anthropogenic gases, such as carbon dioxide, has increased substantially over the past few decades due to the high level of industrialization and urbanization that is occurring in developing countries, like South Africa. This has escalated the challenges of global warming. In South Africa, carbon capture and storage (CCS) from coal-fired power plants is attracting increasing attention as an alternative approach towards the mitigation of carbon dioxide emission. Therefore, innovative strategies and process optimization of CCS systems is essential in order to improve the process efficiency of this technology in South Africa. This review assesses the potential of CCS as an alternative approach to reducing the amount CO 2 emitted from the South African coal-fired power plants. It examines the various CCS processes that could be used for capturing the emitted CO 2 . Finally, it proposes the use of new adsorbents that could be incorporated towards the improvement of CCS technology.

“…CO 2 in the dense phase is particularly sensitive to the existence of steep elevations and impurities. This does not only impact on the repressurisation distance in the pipeline system, but also affects the fluid dynamics and thermodynamic behaviour of the CO 2 stream, resulting in different flow regimes that alter the pipeline operating conditions [38,[51][52][53][54][55][56][57][58][59]. Detailed consideration is required to get the optimal pipeline sizing, distance before repressurisation, and the number of pumps/size of pumping or compressor stations, as well as their energy requirements [27,[60][61][62][63].…”

Transport of carbon dioxide (CO 2 ) via pipeline from the point of capture to a geologically suitable location for either sequestration or enhanced hydrocarbon recovery is a vital aspect of the carbon capture and storage (CCS) chain. This means of CO 2 transport has a number of advantages over other means of CO 2 transport, such as truck, rail, and ship. Pipelines ensure continuous transport of CO 2 from the capture point to the storage site, which is essential to transport the amount of CO 2 captured from the source facilities, such as fossil fuel power plants, operating in a continuous manner. Furthermore, using pipelines is regarded as more economical than other means of CO 2 transportThe greatest challenges of CO 2 transport via pipelines are related to integrity, flow assurance, capital and operating costs, and health, safety and environmental factors. Deployment of CCS pipeline projects is based either on point-to-point transport, in which case a specific source matches a specific storage point, or through the development of pipeline networks with a backbone CO 2 pipeline. In the latter case, the CO 2 streams, which are characterised by a varying impurity level and handled by the individual operators, are linked to the backbone CO 2 pipeline for further compression and transport. This may pose some additional challenges.This review involves a systematic evaluation of various challenges that delay the deployment of CO 2 pipeline transport and is based on an extensive survey of the literature. It is aimed at confidence-building in the technology and improving economics in the long run. Moreover, the knowledge gaps were identified, including lack of analyses on a holistic assessment of component impurities, corrosion consideration at the conceptual stage, the effect of elevation on CO 2 dense phase characteristics, permissible water levels in liquefied CO 2 , and commercial risks associated with project abandonment or cancellation resulting from high project capital and operating costs.2
