A Comparison of Post-combustion Capture Technologies for the NGCC

CO2 capture from reheating furnace based on the sensible heat of continuous casting slabs

“…The CO 2 concentration after purification is 98.4%, which can be used for enhanced oil recovery. References 32,33 showed that the specific regeneration energy is about 4.0 MJ/kgCO 2 for MEA absorption in NGCC power plants. Figures 6 and 7 show CO 2 mole fraction and temperature profiles in the absorber and stripper, respectively.…”

“…This paper is based on the flue gas of the reheating furnace, and the CO 2 concentration of reheating furnace is much lower than that in coal-fired power plants (~15 mol %), but approximate to the concentration of natural gas combined cycle (NGCC) power plants (4-12 mol %). References 32,33 showed that the specific regeneration energy is about 4.0 MJ/kgCO 2 for MEA absorption in NGCC power plants. The simulation results in this paper are within the range of coal-fired power plants, and close to NGCC power plants, so the results are considered to be quite reasonable.…”

Offshore power generation with carbon capture and storage to decarbonise mainland electricity and offshore oil and gas installations: A techno-economic analysis

“…This would result in an LCOE decrease of 6.2 and 6.9 % for the concept delivering power to, respectively, mainland and offshore oil and gas platforms. Regarding CO2 capture technologies [17], an alternative case considering a 40% reduction in capture and conditioning energy penalty and a 20% reduction in investments and non-fuel operating costs is investigated. Although other capture technologies than solvent could reach these targets, it is worth noting that recent solvent developments have displayed a promising potential to reduce both energy and cost penalties [74].…”

“…Meanwhile, other studies have sought cost reduction opportunities through development of novel capture technologies. Several studies reported that these technologies could achieve significant reductions in CO2 capture energy penalty [17]. Turi et al [18] reported that a membrane-based process could lower the CO2 capture energy penalty by up to 38%.…”

Feasibility of Selective Exhaust Gas Recycle Process for Membrane-based CO2 Capture from Natural Gas Combined Cycles – Showstoppers and Alternative Process Configurations

“…Membrane-based post-combustion capture from NGCC is however challenging due to the low CO 2 concentration in the NGCC exhaust gas (3-4 vol%). Exhaust Gas Recirculation (EGR) has the potential to increase the CO 2 concentration in flue gas to around 8 vol% [2], however membrane-based post-combustion capture is still not competitive at these conditions [3]. Merkel et al [4] presented a novel Selective Exhaust Gas Recycle (S-EGR) scheme to increase the exhaust gas CO 2 concentration to 15-20 vol%.…”
