“…The raw syngas from the gasification process mainly consisted of carbon monoxide (CO) and hydrogen (H 2 ), and a small quantity of contaminant compounds such as hydrogen-sulfide (H 2 S) and carbonyl sulfide (COS), oxides of carbon and sulfur such as carbon dioxide (CO 2 ) and sulfur dioxide (SO 2 ), nitrogen compounds such as ammonia (NH 3 ), hydrogen cyanine (HCN), Hg, and particulates from the mineral fraction of the coal such as unconverted carbon and ash [32]. Some of the corrosive components such as sulfide, nitride, and dust were removed in this cleaning section.…”

Abstract:The methodology of life-cycle assessment was applied in order to evaluate the environmental performance of a hypothetical Saskatchewan lignite-fueled Integrated Gasification Combined Cycle (IGCC) electricity generation, with and without pre-combustion carbon dioxide (CO 2 ) capture from a full life-cycle perspective. The emphasis here is placed on environmental performance associated with air contaminants of the comparison between IGCC systems (with and without CO 2 capture) and a competing lignite pulverized coal-fired electricity generating station in order to reveal which technology offers the most positive environmental effects. Moreover, ambient air pollutant modeling was also conducted by using American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) air dispersion modeling to determine the ground-level concentration of pollutants emitted from four different electricity generating stations. This study assumes that all stations are located close to Estevan. The results showed a significant reduction in greenhouse gas (GHG) emissions and acidification potential by applying both post-combustion and pre-combustion CO 2 capture processes. The GHG emissions were found to have reduced by 27%-86%, and IGCC systems were found to compare favorably to pulverized coal systems. However, in other environmental impact categories, there are multiple environmental trade-offs depending on the capture technology used. In the case of post-combustion capture, it was observed that the environmental impact category of eutrophication potential, summer smog, and ozone depletion increased due to the application of the CO 2 capture process and the surface mining coal operation. IGCC systems, on the other hand, showed the same tendency as the conventional coal-fired electricity generation systems, but to a lesser degree. This is because the IGCC system is a cleaner technology that produces lower pollutant emission levels than the electricity generating station; thus, the benefits of capture are reduced on a comparative basis. The results from air dispersion analysis showed that the maximum ground-level concentrations of pollutants from all electricity generating stations are in compliance with all air quality standards, except for Co, Pb and Ni. The IGCC with capture revealed the lowest nitrogen dioxide (NO 2 ) ground-level concentration compared to all other scenarios. Moreover, IGCC systems both with and without pre-combustion CO 2 capture revealed no ground-level concentration of trace elements. This is because the IGCC system operates with an acid gas cleaning process that removes most of the trace contaminants from the syngas.

“…The shift reaction was repeated in the second reactor with a lower temperature than the first reactor. The syngas that left the WGS reactor had a much higher H 2 composition than the raw syngas with the CO conversion of 90% [32,33].…”

“…In the same study a BIGCC plant with CCS and net generation of 123 MW el might present a lower HHV efficiency ($28%), higher capital costs (approximately 1730 $/kW) while its COE could be as high as 0.082 $/kWh due to the high CCS costs. In a more recent study [9], higher net efficiencies are envisaged for the close future due to ongoing improvements on IGCC technology and some interesting data for IGCC plants already installed are listed within a capacity range 100-545 MW el . The assumptions for IGCC technology indicate capital costs $1450 $/kW, and net HHV efficiency in the range 40-50% provided that a CCS system is not installed.…”

“…IGCC pilot plants and industrial-scale demonstrations plants have shown potential for this technology to be implemented in commercial-scale; however; this technology still requires improvement in terms of process economics to become fully competitive [5]. Also, reliability and availability have challenged the development and commercialization of IGCC power plants in terms Pre-combustion technology [14] Lignite coal Units to be completed in the first half of 2013, non-slagging transport reactor integrated gasifier (TRIG) & two Siemens SGT6-5000F gas turbine Nakoso (Japan) 2014 500-600…”
