“…However, recent works on multi-stage separation and vacuum permeate pumping have shown promise toward cost-effective CO 2 capture using membranes (Hasan et al, 2012a;Zhang et al, 2013;Ho et al, 2006;Kaldis et al, 2004;Hägg and Lindbråthen, 2005). Similar to adsorption-based processes, membrane-based processes also require the selection of an appropriate membrane materials from different polymeric, facilitated transport, inorganic and mixed matrix membranes which show potential for CO 2 capture (Powell and Qiao., 2006;Ramasubramanian et al, 2013;Shah et al, 2012;Bernardo et al, 2009).…”

a b s t r a c tWe present a multi-scale framework for the optimal design of CO 2 capture, utilization, and sequestration (CCUS) supply chain network to minimize the cost while reducing stationary CO 2 emissions in the United States. We also design a novel CO 2 capture and utilization (CCU) network for economic benefit through utilizing CO 2 for enhanced oil recovery. Both the designs of CCUS and CCU supply chain networks are multi-scale problems which require decision making at material, process and supply chain levels. We present a hierarchical and multi-scale framework to design CCUS and CCU supply chain networks with minimum investment, operating and material costs. While doing so, we take into consideration the selection of source plants, capture processes, capture materials, CO 2 pipelines, locations of utilization and sequestration sites, and amounts of CO 2 storage. Each CO 2 capture process is optimized, and the best materials are screened from large pool of candidate materials. Our optimized CCUS supply chain network can reduce 50% of the total stationary CO 2 emission in the U.S. at a cost of $35.63 per ton of CO 2 captured and managed. The optimum CCU supply chain network can capture and utilize CO 2 to make a total profit of more than 555 million dollars per year ($9.23 per ton). We have also shown that more than 3% of the total stationary CO 2 emissions in the United States can be eliminated through CCU networks at zero net cost. These results highlight both the environmental and economic benefits which can be gained through CCUS and CCU networks. We have designed the CCUS and CCU networks through (i) selecting novel materials and optimized process configurations for CO 2 capture, (ii) simultaneous selection of materials and capture technologies, (iii) CO 2 capture from diverse emission sources, and (iv) CO 2 utilization for enhanced oil recovery. While we demonstrate the CCUS and CCU networks to reduce stationary CO 2 emissions and generate profits in the United States, the proposed framework can be applied to other countries and regions as well.

“…2 shows various approaches to capturing CO 2 from flue gas or air. Typically, CO 2 capture technologies can be classified into several categories: (1) absorption using alkaline solutions (Yu et al, 2012;Lin and Chu, 2015); (2) adsorption using zeolite (Lee et al, 2013), activated carbon , and metal organic frameworks (Ganesh et al, 2014); (3) mineral carbonation using natural ores and/or solid wastes (Olivares-Marín and Maroto-Valer, 2012); (4) selective membrane Ramasubramanian et al, 2013); (5) cryogenic (Wang and Gan, 2014); (6) high-temperature solid looping processes such as calcium looping (Chang et al, 2013) and chemical looping (Chiu and Ku, 2012); (7) ionic liquid (Zhang et al, 2012); and (8) biological including microalgae and enzymebased processes (Klinthong et al, 2015). Some of the above capture technologies, such as mineral carbonation and biological methods, are directly related to utilization or conversion because the physicochemical property of CO 2 is changed after capture.…”

This paper provides an overview of state-of-the-art carbon fixation and utilization technologies. Several carbon capture processes, such as chemical absorption and chemical looping, are reviewed and illustrated. In addition, various types of chemicals and fuels that can be produced using concentrated CO 2 (or other forms) through physical, chemical, or enhanced biological methods are presented. Among those carbon conversion methods, two promising approaches, i.e., microalgae ponds and accelerated carbonation using alkaline solid wastes, are reviewed in detail. Microalgae are fast-growing and ubiquitous photosynthetic organisms, which are rich in protein and can be converted to biodiesel fuel. They have been recognized as an alternative feedstock not only because they use CO 2 from the atmosphere but also due to their high lipid content per biomass compared to other plants. In this study, for the microalgae technologies, the principles and applications of open pond systems are discussed in terms of both technological and economic considerations. The important operation parameters affecting productivity of microalgae, including light intensity, temperature, mixing, CO 2 delivery, accumulation of dissolved oxygen, and salinity are summarized. On the other hand, accelerated carbonation technologies are an attractive and feasible approach to integrating alkaline solid waste treatment with CO 2 fixation and utilization. In this study, the performance of various carbonation processes is critically reviewed from the perspectives of process design, energy consumption, and environmental benefits. The carbonated solid product can also be used as supplementary cementitious materials in a blended cement or concrete block. Accordingly, the performance of cement pastes with carbonated product, in terms of workability and strength development, are evaluated from the cement chemistry point of view. Cement manufacturing is an energy and material intensive process, with high annual production. It is noted that, through the accelerated carbonation process, significant indirect environmental benefits can be realized.

“…However, facilitated transport membranes have a major potential drawback of saturation of carriers under an elevated pressure. [7][8][9][10] Immobilization of suitable room-temperature ionic liquids in a porous support to form supported liquid membranes may increase the solubility of the fast permeating gas and thus 3 increase the permselectivity. However, the long term stability of supported liquid membranes remains a challenge for practical applications.…”
