“…The drying of flue gas for post-combustion CO 2 capture process incurs high-energy demands and is thus often considered impractical. [22][23][24] If flue gas can be dried, however, the options available for CO 2 capture broaden considerably. In our process, flue gas drying is carried out in three stages, first using cooling water from the plant, then taking advantage of Joule-Thomson cooling from the subambient process, and finally, an adsorbent dryer bed.…”

“…20,21 These issues with scale lead to the commonly held opinion, for membrane and adsorptive capture processes in particular, that additional pretreatment beyond the already existing infrastructure for CO 2 capture from dilute point sources will result in impractical economics. [22][23][24] In this article, we will reexamine this assumption. Inspired by the work of Hasse et al and others, who proposed a sub-ambient membrane process that required considerable pretreatment, the work discussed here primarily focuses on the holistic design of the subambient CO 2 capture process for any separation process that relies on pressure driving forces (in particular, membranes and pressure swing adsorption [PSA]).…”

Adsorption of CO 2 from post-combustion flue gas is one of the leading candidates for globally impactful carbon capture systems. This work focused on understanding the opportunities and limitations of sub-ambient CO 2 capture processes utilizing a multistage separation process. A hybrid process design using a combination of pressure-driven separation of CO 2 from flue gas (e.g., adsorption-or membrane-based separation) followed by CO 2 -rich product liquefaction to produce high-purity (>99%) CO 2 at pipeline conditions is considered. The operating pressure of the separation unit is a key cost parameter and also an important process variable that regulates the available heat removal necessary to reach the sub-ambient operating conditions. The economic viability of applying pressure swing adsorption (PSA) processes using fiber sorbent contactors with internal heat management was found to be most influenced by the productivity of the adsorption system, with productivities as high as 0.015 mol CO 2 /kg sorb À1 sec À1 being required to reduce costs of capture below $60/ ton CO 2 captured. This analysis was carried out using a simplified two-bed process, and thus there is opportunity for further cost reduction with exploration of more complex cycle designs. Three exemplar fiber sorbents (MIL-101(Cr), UiO-66, and zeolite 13X) were considered for application in the sub-ambient process of PSA unit.Among the considered sorbents, zeolite 13X fiber composites were found to perform better at ambient temperatures as compared to sub-ambient. MIL-101(Cr) and UiO-66 fiber composites had improved purity, recovery, and productivity at colder temperatures reducing costs of capture as low as $61/ton CO 2 . Future economic improvement could be achieved by reducing the required operating pressure of the PSA unit and pushing the Pareto frontier closer to the final pipeline requirement via a combination of PSA cycle design and material selection.

“…Finally, the bed is cooled to start another cycle of adsorption [82][83][84][85]. In general, the main limitations of this process are the reduction in the adsorption capacity when the FG stream is wet due to the hydrophilic character of the materials [86] and the low q (Table 2), which necessitates a large amount of material to achieve more quantities of captured CO 2 . However, the adsorption process can be adapted to several operation conditions because of its flexibility to configure the reactors [86][87][88].…”

The transport sector powered by internal combustion engines (ICE) requires novel approaches to achieve near-zero CO2 emissions. In this direction, using CO2 capture and storage (CCS) systems onboard could be a good option. However, CO2 capture in mobile sources is currently challenging due to the operational and space requirements to install a CCS system onboard. This paper presents a systematic review of the CO2 capture in ICE driven transport to know the methods, techniques, and results of the different studies published so far. Subsequently, a case study of a CCS system working in an ICE is presented, where the energy and space needs are evaluated. The review reveals that the most suitable technique for CO2 capture is temperature swing adsorption (TSA). Moreover, the sorbents with better properties for this task are PPN-6-CH2-DETA and MOF-74-Mg. Finally, it shows that it is necessary to supply the energy demand of the CCS system and the option is to take advantage of the waste heat in the flue gas. The case study shows that it is possible to have a carbon capture rate above 68% without affecting engine performance. It was also found that the total volume required by the CCS system and fuel tank is 3.75 times smaller than buses operating with hydrogen fuel cells. According to the review and the case study, it is possible to run a CCS system in the maritime sector and road freight transport.
