“…More research is needed to determine the potential for cost reductions by achieving a higher level of heat integration between the post-combustion capture unit and the industrial plants, particularly the refineries. Johansson et al (2012) showed that the utilization of excess heat for post-combustion CO 2 capture in the process industry can drive down avoidance costs to the same cost range as reported for oxyfuel combustion in industry (30-60 D /t CO 2 avoided (Kuramochi et al, 2012)), and post-combustion capture in the power sector (30-40 D /t CO 2 avoided; ZEP, 2011). The advent of solvents with low regeneration temperatures could result in even further cost reductions.…”

To date, literature often presents generic results on the techno-economic performance of CO 2 capture in industry. Insufficient knowledge is available on the impact of site-specific factors on the feasibility of CO 2 capture at industrial plant level. This article presents a techno-economic analysis and an inventory of potential implementation and operational challenges related to the three main CO 2 capture technologies applied at industrial plant level for the short term (2020-2025) and long term (2040-2050). Five industrial plants from various industrial sectors (a medium and large sized petroleum refinery, a small and medium sized chemical plant, and a large hydrogen plant) in the Netherlands were used for this study. The results show the lowest CO 2 avoidance costs for the refineries (24-57 D /t) and chemical plants (37-124 D /t) when operated in oxyfuel combustion mode, both for the short and long term, although post-combustion is economically preferable for the smallest chemical plant (117 D /t) in the short term. For the hydrogen plant, avoidance costs (67 D /t) are lowest when capturing CO 2 solely from the highpressure process gas. For the short term cases, spatial constraints on existing plant sites could increase the indicated CO 2 avoidance costs, especially for post-combustion capture; for the long term cases, newbuilt capture ready process units, plant integration and optimized utilities are expected to lower the avoidance costs for all three capture technologies.

“…The values for the economic lifetime found in literature range between 15 and 25 years (e.g. IEA GHG, 2000;Johansson et al, 2012;Kuramochi et al, 2012a;Switzer et al, 2005). The impact of the annual operating time and economic lifetime on the final results is examined indirectly by varying the total annualized capital costs (±30%) in the sensitivity analysis.…”

This article presents a method to assess deployment pathways for CO 2 capture infrastructure configurations in industrial zones. This method was demonstrated for the Botlek area consisting of 16 emitters (7.1 MtCO 2 /y). Pathways were developed for two optimal infrastructures: Post-Recsor based on postcombustion capture and Oxy-Hybrid based on oxyfuel capture (see part A). The pathways vary regarding the sequence and timing in which industrial plants are equipped with CCS, number of buildout phases, and whether capture equipment is oversized or not. Results show that Post-Recsor and Oxy-Hybrid can be realized in three phases while maintaining most cost advantages of an 'all-at-once' strategy (Post-Recsor: 94-97 D /tCO 2 ; Oxy-hybrid: 61-64 D /tCO 2) compared to CO 2 capture at industrial plant level (Post-Decentral: 100 D /tCO 2 ; Oxy-Decentral: 66 D /tCO 2). A fast deployment results in lower levelized avoidance costs (Post-Recsor: 86-88 D /tCO 2 ; Oxy-Hybrid: 55-58 D /tCO 2) and higher cumulative avoided emissions (Post-Recsor: 120-122 MtCO 2 ; Oxy-Hybrid: 116-117 MtCO 2) over a period of twenty years. This strategy requires a sufficiently high CO 2 price and a rapid replacement of the capital stock. Oversizing is economically interesting for oxyfuel pathways with a fast deployment, regardless of the discount rate. For post-combustion, oversizing is only feasible under a fast deployment and low discount rate.

“…In the literature alternative methods of supplying the heat for the desorption process are examined. The production of heat in an external source powered by a biomass boiler is analyzed in [4]. However, in [5][6][7] variant in which heat is extracted from the flue gas leaving the gas turbine assembly is analyzed.…”

The article presents the results of thermodynamic analysis of the supercritical coal-fired power plant with gross electrical output of 900 MW and a pulverized coal boiler. This unit is integrated with the absorption-based CO2 separation installation. The heat required for carrying out the desorption process, is supplied by the system with the gas turbine. Analyses were performed for two variants of the system. In the first case, in addition to the gas turbine there is an evaporator powered by exhaust gases from the gas turbine expander. The second expanded variant assumes the application of gas turbine combined cycle with heat recovery steam generator and backpressure steam turbine. The way of determining the efficiency of electricity generation and other defined indicators to assess the energy performance of the test block was showed. The size of the gas turbine system was chosen because of the need for heat for the desorption unit, taking the value of the heat demand 4 MJ/kg CO2. The analysis results obtained for the both variants of the installation with integrated CO2 separation plant were compared with the results of the analysis of the block where the separation is not conducted. 56 J.
