“…The efficiency losses incurred by the gasification of the coal in an IGCC are not affected by the CO 2 capture efficiency penalty as they are the same for the non-capture and capture case. To date CO 2 capture in IGCC power plant has only been tested and demonstrated at pilot scale ) (Casero et al, 2014.…”

“…340-360 • C reactor inlet temperature) is very large at typically 2.4 kg.kg −1 (equaling overall steam/CO = 4.9 mol.mol −1 ) (van Dijk et al, 2014), . For start-of-life conditions as demonstrated in the Elcogas pre-combustion demonstration plant (Casero et al, 2014), the inlet temperature is much lower at around 300 • C and, accordingly the required steam/dry syngas ratio is lower at steam/CO = 3.0 mol.mol −1 (Casero et al, 2014). To limit the steam requirement, a split flow configuration can be applied in which the syngas is distributed together with quench water in between the reactors (Carbo et al, 2009a) (Carbo et al, 2009b).…”

This paper, which is part of a special issue of the International Journal of Greenhouse Gas Control, gives an overview of the latest achievements in the pre-combustion decarbonisation route for the production of electricity with CO2 capture. Pre-combustion technologies applied to two different fuels are considered, natural gas and coal, since they cover most of electricity production from fossil fuels worldwide. The work first discusses in detail the different sections in which a power plant with pre-combustion CO2 capture can be divided. For each section, the available technologies with corresponding advantages and disadvantages are presented. Next, the plant lay-outs for natural gas and coal proposed in literature, including heat & mass balances and the economic assessment, are discussed. In general, research activity in pre-combustion decarbonisation for power production focused more on coal than on natural gas-based plant since in the latter case the plant complexity and costs are not competitive with post-combustion CO2 capture, which is a technology on the verge of commercialization. Finally the paper briefly discusses pre-combustion CO2 capture in industry especially those projects where CO2 is captured and stored or used for EOR

“…Physical absorption-based pre-combustion capture, and capture following oxy-fuel combustion, are another two promising technologies for CO 2 capture, which are commonly studied [17][18][19][20]. Oxy-fuel combustion involves burning the fuel in a mixture of pure oxygen and recycled CO 2 (the CO 2 serves as thermal ballast, to reduce the overall flame temperature, which would be exceedingly high for a mixture of pure oxygen and fuel).…”

A B S T R A C TCarbon dioxide (CO 2 ) emitted from conventional coal-based power plants is a growing concern for the environment. Chemical looping combustion (CLC), pre-combustion and oxy-fuel combustion are promising CO 2 capture technologies which allow clean electricity generation from coal in an integrated gasification combined cycle (IGCC) power plant. This work compares the characteristics of the above three capture technologies to those of a conventional IGCC plant without CO 2 capture. CLC technology is also investigated for two different process configurations-(i) an integrated gasification combined cycle coupled with chemical looping combustion (IGCC-CLC), and (ii) coal direct chemical looping combustion (CDCLC)-using exergy analysis to exploit the complete potential of CLC. Power output, net electrical efficiency and CO 2 capture efficiency are the key parameters investigated for the assessment. Flowsheet models of five different types of IGCC power plants, (four with and one without CO 2 capture), were developed in the Aspen plus simulation package. The results indicate that with respect to conventional IGCC power plant, IGCC-CLC exhibited an energy penalty of 4.5%, compared with 7.1% and 9.1% for precombustion and oxy-fuel combustion technologies, respectively. IGCC-CLC and oxy-fuel combustion technologies achieved an overall CO 2 capture rate of $100% whereas pre-combustion technology could capture $94.8%. Modification of IGCC-CLC into CDCLC tends to increase the net electrical efficiency by 4.7% while maintaining 100% CO 2 capture rate. A detailed exergy analysis performed on the two CLC process configurations (IGCC-CLC and CDCLC) and conventional IGCC process demonstrates that CLC technology can be thermodynamically as efficient as a conventional IGCC process.

“…Indeed, the large-scale application of PSA for the separation of H 2 and CO 2 has been demonstrated at the Puertellano IGCC power plant in Spain owned by ELCOGAS. 14 The hydrogen purification unit obtains hydrogen with 99.99% purity from raw hydrogen coming from the separation unit. The PSA steps consist of an adsorption multibed system containing activated carbon, alumina, and a molecular sieve.…”

Carbon Dioxide Separation from Nitrogen/Hydrogen Mixtures over Activated Carbon Beads: Adsorption Isotherms and Breakthrough Studies

The high-pressure separation of carbon dioxide/nitrogen and carbon dioxide/hydrogen mixtures was investigated over two phenolic-resin-derived activated carbon bead samples: an unmodified activated carbon made from a phenolic resin precursor and a modified material manufactured by treating the former activated carbon with first nitric acid and then ammonia. Equilibrium tests on the material were performed with a high-pressure volumetric analysis with carbon dioxide and nitrogen. The dynamic response of the separation was tested using a fixed-bed rig to produce carbon dioxide breakthrough curves with several carbon dioxide feed fractions (0.1, 0.2, 0.3, 0.4, and 0.5) in nitrogen. This study represents one of the few studies that equilibrium capacities have been related to the breakthrough capacities achieved in packed-bed operation for high-pressure carbon dioxide capture applications and the first to apply the ideal adsorbed solution theory (IAST) model. The equilibrium tests showed that the Langmuir−Freundlich isotherm and the dual-site Langmuir isotherm gave a closer fit to all of the data than the Langmuir isotherm alone in the pure component adsorption studies. The capacity of the material based on the dynamic separation was found with mole fractions of 0.5 carbon dioxide in nitrogen leading to 6.09 mol kg −1 carbon dioxide being captured over the unmodified activated carbon and 7.48 mol kg −1 being captured over the modified activated carbon at 25 bar and 25°C. By comparison, the saturation capacity of the modified activated carbon in the Langmuir−Freundlich fit to the high-pressure volumetric adsorption data for 0.5 mole fraction carbon dioxide at the same temperature was 8.06 mol kg −1 for the unmodified material and 7.68 mol kg −1 for the modified material based on the pure component isotherm parameters. The breakthrough capacities were also found for feed fractions of carbon dioxide in the range of 0.1−0.5. A comparison between the dynamic capacities and those predicted by the isotherm show that pure component data are not necessarily representative of a dynamic multi-component system. Therefore, multi-component isotherm models were fitted to the data and compared to predictions using the IAST. A multi-component dual-site Langmuir equation was found to give the best fit to the binary component data. Breakthrough curves were also reported for carbon dioxide in hydrogen over the modified activated carbon, with the carbon beads showing considerable potential for application for carbon capture in pre-combustion separation units of power plants, because of their physically strength, meaning no further agglomeration of powdered samples is required for their use in packed beds.
