“…The final capture ratio and CO2 purity in each scenario are assigned to be 90% and 95% (mol), respectively. The parameters are mainly from literature, industrial data and engineering heuristics (Anantharaman et al, 2010;Favre, 2011;Husebye et al, 2012;Hussain and Hagg, 2010;Merkel et al, 2010;Stern, 1968;Zhang et al, 2012a), and also based on the sensitivity analysis in this work.…”

“…The absorber is a simple RadFrac column, whereas the stripper column has a condenser on the top and a reboiler at the bottom. Considering the low efficiency of the gas absorber, it is modeled with a Murphree efficiency of 25~30% (Husebye et al, 2012). In the MEA-based CO2 capture process, another major issue is the degradation of the solvents through the irreversible side reactions with other flue gas components as SO2, NOx and O2, leading to solvent losses and degradation wastes (Ho et al, 2011;Koornneef et al, 2008;Portal, 2011).…”

An integrated framework focusing on the energetic analysis and environmental impacts of a CO2 capture and storage (CCS) system is presented, in which the process simulation method and the life cycle assessment (LCA) method are integrated and applied to the CCS value chain.Three scenarios for carbon capture from post-combustion power plant -an MEA-based system, a gas separation membrane process and a hybrid membrane-cryogenic process are studied. The energy efficiency of power plant and the specific capture energy consumption for each scenario are estimated from process simulation. The environmental impacts for each scenario and the base case without CCS are assessed with LCA method. The results show that the MEA-based capture system faces the challenges of higher energy consumption, and higher environmental impact caused by solvent degradation and emissions compared to gas membrane separation processes. The hybrid membrane-cryogenic process shows a better environmental potential for CO2 capture from flue gases due to much lower power consumption and relatively lower environmental impacts.

“…This mix is separated from the gases by flashing (F204), leading to a 61 wt.% ethanol concentration and 96 % recovery. The gas stream containing carbon dioxide and non‐consumed CO and H 2 is treated in a monoethanolamine (MEA)‐based process to remove the CO 2 . The remaining fractions of CO and H 2 are mixed with fresh syngas and then fed back to the fermenter.…”

“…The final product purity is 99.8 wt.% (the remaining 0.2 % is water) with an overall recovery of 99.9%. Similarly as for the ethanol DSP, this DSP also includes CO 2 removal (by the MEA‐based process) from the recycling of off‐gas due to its partial consumption during fermentation stage.…”

“…CAPEX was based on multiple factors related to the total equipment purchase costs (EPC), which in turn depends on individual equipment's characteristic size. The EPC of this study were adapted from multiple sources: the NREL's reports for all equipment used in the syngas production process and also for ‐adsorbers; Seider et al for membrane‐based operations and compressors; http://matche.com for fermentors; Husebye et al . for the CO 2 MEA‐based process; SuperPro Designer V9.0 for centrifuges; and Aspen Plus V8.8 for typical processing equipment such as distillation columns, extraction units, heat exchangers, evaporators, condensers and flash separators.…”

This study presents the design and assessment of site‐specific supply chains and related manufacturing processes for the production of bio‐based chemicals from the syngas platform and via gasification of lignocellulosic biomass followed by syngas fermentation. The supply chains include feedstocks production and collection, biomass gasification, syngas fermentation, and downstream processing. For each of these stages, different alternatives were considered: four feedstocks (pine, corn stover, sugarcane bagasse, and eucalyptus), three products (ethanol, 2,3‐butanediol and hexanoic acid), and three geographical locations (the Netherlands, the USA, and Brazil). Conceptual development and analysis of the supply chains were done through the combination of different design and assessment tools, namely biomass supply chains design, fermentation process design (based on thermodynamics and transport), process simulation, and economic and environmental assessments. The minimum selling price (MSP) and two environmental impact categories, i.e., global warming potential (GWP) and non‐renewable energy use (NREU), were used as performance indicators. These were compared to data reported in scientific literature and commercial sources for similar processes and products. The best overall performance was obtained for the production of 2,3‐butanediol from pine sourced in the USA. In the cases of ethanol and hexanoic acid, the syngas fermentation stage had significant contributions to MSP, GWP, and NREU, due mainly to its high energy requirements. Regarding the geographical location, the best economic performance was obtained for the USA followed by the Netherlands and Brazil respectively. Furthermore, operation in Brazil led to the lowest environmental impacts, followed by the Netherlands and the USA. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd

This article addresses the sustainable design of hydrogen (H2) production systems that integrate brown and blue pathways with green hydrogen infrastructure. We develop a systematic framework to simultaneously optimize the process superstructure and operating conditions of steam methane reforming (SMR)‐based hydrogen production systems. A comprehensive superstructure that integrates SMR with multiple carbon dioxide capture technologies, electrolyzers, fuel cells, and working fluids in the organic rankine cycle is proposed under varying operating conditions. A life cycle optimization model is then developed by integrating superstructure optimization, life cycle assessment approach, techno‐economic assessment, and process optimization using extensive process simulation models and formulated as a mixed‐integer nonlinear program. We find that the optimal unit‐levelized cost of hydrogen ranges from $1.49 to $3.18 per kg H2. Moreover, the most environmentally friendly process attains net‐zero life cycle greenhouse gas emissions compared to 10.55 kg CO2‐eq per kg H2 for the most economically competitive process design.
