“…The authors recommended the combustion process improvement via dividing the OTR into a series of units and adding the fuel at stages along the reactor network. Zanganeh et al used simulated process data to provide a comparison between different options for CO 2 capture in the case of refinery oxy‐fuel combustion. They conducted simulations and cost analysis for oxycombustion combined with CO 2 capturing of 2‐refinery fuel gases considering four different modes of combustion.…”

Summary The increased level of emissions of carbon dioxide into the atmosphere due to burning of fossil fuels represents one of the main barriers toward the reduction of greenhouse gases and the control of global warming. In the last decades, the use of renewable and clean sources of energies such as solar and wind energies has been increased extensively. However, due to the tremendously increasing world energy demand, fossil fuels would continue in use for decades which necessitates the integration of carbon capture technologies (CCTs) in power plants. These technologies include oxycombustion, pre‐combustion, and post‐combustion carbon capture. Oxycombustion technology is one of the most promising carbon capture technologies as it can be applied with slight modifications to existing power plants or to new power plants. In this technology, fuel is burned using an oxidizer mixture of pure oxygen plus recycled exhaust gases (consists mainly of CO2). The oxycombustion process results in highly CO2‐concentrated exhaust gases, which facilitates the capture process of CO2 after H2O condensation. The captured CO2 can be used for industrial applications or can be sequestrated. The current work reviews the current status of oxycombustion technology and its applications in existing conventional combustion systems (including gas turbines and boilers) and novel oxygen transport reactors (OTRs). The review starts with an introduction to the available CCTs with emphasis on their different applications and limitations of use, followed by a review on oxycombustion applications in different combustion systems utilizing gaseous, liquid, and coal fuels. The current status and technology readiness level of oxycombustion technology is discussed. The novel application of oxycombustion technology in OTRs is analyzed in some details. The analyses of OTRs include oxygen permeation technique, fabrication of oxygen transport membranes (OTMs), calculation of oxygen permeation flux, and coupling between oxygen separation and oxycombustion of fuel within the same unit called OTR. The oxycombustion process inside OTR is analyzed considering coal and gaseous fuels. The future trends of oxycombustion technology are itemized and discussed in details in the present study including: (i) ITMs for syngas production; (ii) combustion utilizing liquid fuels in OTRs; (iii) oxy‐combustion integrated power plants and (iv) third generation technologies for CO2 capture. Techno‐economic analysis of oxycombustion integrated systems is also discussed trying to assess the future prospects of this technology. Copyright © 2017 John Wiley & Sons, Ltd.

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.

“…Subbituminous coal (Highvale), at which composition is given in Table 3.15, is assumed as the fuel burned in producing electricity. The conversion efficiency of the coal plant is 42% [Zanganeh et al, 2004] and its equivalent CO 2 emission is calculated based on the high heating value (HHV) of the Highvale coal. additional HX operation is added (HTEX-4C) to produce steam for power generation.…”
