In this chapter, a general description of data-mining techniques is done in the context of IGCC operation. The different control philosophies applicable to IGCC operation are discussed together with different examples of data reconciliation based on process simulation. The problem of process monitorisation, as an example of data-mining application, is extensively discussed and an approach based on PCA is presented. © Springer-Verlag London Limited 2011. Source

The description of the 335 MWeISO coal-based Puertollano IGCC power plant as example of industrial application of IGCC technology together with its main lessons learnt are summarised in this chapter. This chapter includes process description, syngas analysis, main operational real data (power production and emissions), and main causes of unavailability as well as R&D lines. These are mainly focused on improvement of IGCC technology taking into account efficiency increase and emissions reduction. So, first results of the CO2 capture and H2 co-production 14MWth pilot plant installed in the Puertollano IGCC are included. © Springer-Verlag London Limited 2011. Source

Catalysis Today

The effects of the addition of alkali metal and alkali-earth metal promoters over cobalt based catalyst on Fischer-Tropsch activity and on hydrocarbon product distribution were studied. The influence of promoters on the reducibility and cobalt particle size was studied by different techniques, including N2 adsorption, X-ray diffraction, temperature-programmed reduction, temperature-programmed desorption and acid-base titrations. Experiments were carried out on a bench scale fixed bed reactor and catalysts were prepared by incipient wetness impregnation. It was observed that the addition of small amounts of these promoters (0.5 wt%) improved the cobalt oxide reducibility by reducing the formation of cobalt aluminate species. The interaction between cobalt oxide and promoted support was reduced and larger cobalt oxide particles were formed on the surface. A positive correlation between basicity and particle size was observed with the exception of K promoted sample. Furthermore, CO conversion and C5 + selectivity were found to be also influenced by the addition of promoters. An enhanced dispersion that provides abundant catalytically active sites was observed on promoted catalyst. The addition of Ca to the cobalt based catalyst greatly improved the diesel selectivity. However Ca promoted catalyst yield a higher amount of methane at 242 °C than the Na sample. © 2010 Elsevier B.V. All rights reserved. Source

Greenhouse Gases: Science and Technology

This paper introduces the main research, development and innovation (R&D&I) activities of ELCOGAS related to CO2 emissions reduction. The largest R&D&I investment in the last decade focused on CO2 capture, with the aim of (i) demonstrating the feasibility of CO2 capture and H2 production in an integrated gasifi cation combined cycle (IGCC) that uses solid fossil fuels and residues as feedstock and (ii) obtaining representative economic data. Its main milestone was the commissioning in 2010 of a carbon capture pilot plant integrated in Puertollano IGCC power plant which captured 100 t/d of CO2 while producing 2 t/d of high purity H2, using proven and commercial technology. In this paper, technical results obtained, lessons learnt during the project, as well as, economic data using this pilot plant are reported. ELCOGAS is also acquiring relevant knowledge in the fi eld of co-gasifi cation of biomass. The most recent milestone in this subject is the execution in 2012 of real tests at two levels (2 and 4% in weight) and with two different kinds of biomass (olive oil residue and grape seed meal) pointing at assessing the infl uence of biomass in the IGCC process including CO2 capture within FECUNDUS (RFCR-CT-2010-00009).

This paper introduces the experiences from the operation of a pilot-scale pre-combustion CO2 capture and H2 production plant, and the results obtained in the assessment of various economic scenarios considering the real information coming from this installation unique in the world. The pilot of 14 MWth is in operation since October 2010 in the Puertollano IGCC Plant, and uses proven and commercial technology. Source
