“…Looking at all of these cases the CO 2 emissions vary from 1538 g/kW h to 3864 g/kW h when the systems are operated in electricity generation mode. These figures are significantly higher than the number of an advanced coal fired electricity power station which has CO 2 emissions of 782 g/kW h [31]. However use of CHP instead of power-only generation the CO 2 emissions decrease to a quite low level (between 421 g/kW h and 562 g/kW h).…”

“…In recent years more and more literatures have been focused on CO 2 emissions at power plant level. Through testing an 800 MW e supercritical power plant with specific coal content, Huang et al [5] suggest that emission intensity is 782.88 gCO 2 /KWh. Obiorien et al [6] simulate six power plants in South Africa, with coal-specific as well as unit capacity between 600 and 686 MW e , and their result is among 919-1005 gCO 2 /KWh.…”

Focusing on greenhouse gases (GHGs), this article explores the actual emissions and mitigation burden of coal‐fired power plants in western region of China. Utilizing the 2006 IPCC technology‐detailed methodology, this article developed a coal content‐based GHG measurement system under consideration of N2O emission and SO2 removal, thereafter employed it to evaluate 151 power plants in western China in 2014. At regional level, the three segmented emission sources: CO2 and N2O from coal combustion, and CO2 from sulfur content depreciation, each contributes to emission intensity at 1011.26, 8.24 and 6.09 gCO2e/KWh, respectively. At plant‐specific level, emission intensity is very different, with an average of 1025.60 as well as an interval of 722.38–1796.67 gCO2e/KWh, which implies large gap in mitigation burden among power plants. Comparing mitigation cost of two pathways: CCS technology and carbon market mechanism, it is verified that on average, the former induces electricity price raised by 64.84%–97.26%, while the latter only induces 8.32% upward. From mitigation burden perspective, carbon market is more feasible than CCS technology to motivate power plant to carry out GHGs abatement in the short‐run period. © 2019 American Institute of Chemical Engineers Environ Prog, 38: e13224, 2019

“…It is expected that this alternative minimizes investment and operating costs and increases energy efficiency of CO 2 capture in fossil-fuels power plants [10]. Reboiler duty can be reduced up to 30% in partial oxy-combustion operations in comparison with post-combustion capture based on chemical absorption using MEA [6].Several authors have shown that partial oxycombustion is a technically and economically feasible technology that can provide significantly reductions of both electricity price and CO 2 capture cost [6,11]. Partial oxy-combustion offers some potential advantages for CCS technologies.…”

Development of Partial Oxy-combustion Technology: New Solvents Applied to CO2 Capture in Fossil-fuels Power Plants

Carbon Capture and Storage Technologies (CCS) applied to fossil-fuels power plants have shown some issues that has not been solved yet. Post-combustion using amine-based chemical absorption is a mature and industrially developed technology but the solvent regeneration requires a high-intensive energy consumption. On the other hand, oxy-combustion requires a large amount of high-purity oxygen that can only be supplied by cryogenics. Therefore, the oxygen production is its higher energy penalty. Partial oxy-combustion is a hybrid technology between both technologies that proposes an optimized operation that can lead to further reductions on the overall energy consumption. A comprehensive study of solvents applied in CO 2 capture have been carried out under higher CO 2 partial pressures. Two new solvents, namely HYBRID-1 and HYBRID-2 have been formulated and tested. Results extracted from the experiments with MEA have shown absorption improvements in higher CO 2 concentrated flue gas cases in comparison with air-fired cases (15% v/v CO 2 ). In particular, HYBRID-1 reported the most promising results in terms of equilibrium CO 2 loading and CO 2 absorption rate compared with MEA. HYBRID-1 have been considered as a potential solvent for partial oxy-combustion applications
