“…Each technology has (Wang et al, 2011;Hasan et al, 2012a;Rao and Rubin, 2002;Mores et al, 2011;Rochelle, 2006, 2009;Pellegrini et al, 2011;Rodríguez et al, 2011; Oexmann et al, 2008;Harkin et al, 2010). However, the cost of post-combustion CO 2 capture from power plants using absorption technology, based on monoethanol amine (MEA) solvent, is currently over $70 per metric ton of CO 2 avoided (Raksajati et al, 2013).…”

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.

“…The reactive absorption and desorption of carbon-dioxide with any kinds of amines are always modeled with the rate based modeling technique (Inga von Harbou and Imle, 2014; Moioli and Pellegrini, 2015;Laura et al, 2011;Dawid et al, 2015;Patricia Moresa and Scennaa, 2012;Morteza Afkhamipour, 2013). To the best of the authors' knowledge, however, there is no clear demonstration and/or explanation of the necessity of this model selection.…”

“…The CO 2 recovery technology employed here is a solvent based absorption process. The simulations are so designed to make it relatively simpler to replace the MEA components with any alternate solvent available for CO 2 capture. This can be extended in comparing the efficiency of different solvents.…”

“…They emphasized that PCC is probably the first technology that will be deployed in the existing and new thermal power plants. Laura et al [2] compared energy saving using different solvent with respect to PCC process by doing process simulation and configuration in Aspen platform. For their base line configuration in which 2.1053 kmol/h of CO 2 captured by 30 mass% MEA, they found that the reboiler heat duty was 187.5 kW.…”

Abstract-In this work flowsheet simulation of a coal fired power plant retrofitted with a CO 2 capture unit has been carried out in the AspenPlus process simulator platform. The simulation is an attempt for the detailed process involved in CO 2 capture starting from generation of flue gas, CO 2 capture by monoethanolamine (MEA) and regeneration of solvent using unit operation models available in Aspen Plus and appropriate calculator blocks wherever necessary using FORTRAN codes. The parametric study includes effect of absorber column height, regenerator pressure, on reboiler heat duty and power plant efficiency. Parametric study such as energy penalty on the power plant, reboiler duty of the capture unit, evolution of energy requirement has been done and presented. The contribution of desorption energy is about 47% of the total capture energy and the power plant penalty is about 30% lower when low pressure steam has been utilized to supply heat energy to reboiler. Index Terms-CO 2 capture, MEA, absorption, coal-fired power plant, simulation.
