“…For a 'classical' IGCC power plant, the study was based on the Puertollano [15] scheme operating at 27 bars and where 100% of air feeding the air separation unit (ASU) producing oxygen and nitrogen is extracted from the gas turbine (full integration). As the coal is injected in dry form using pure nitrogen (given by the ASU) as the transportation medium from coal grinder to the gasifier, the necessary steam for the gasification is extracted from the combined cycle.…”

“…We have based our evaluation on the IGCC unit of Puertollano [8,15] revaluated under ISO conditions (1.013 bar, 15°C, 60% relative humidity) and using an international coal (16% ash, 2% moisture and 1% sulfur) instead of the mixture of Puertollano local coal + petroleum coke. Under these 'standard' conditions, the net power of the plant is 326 MW and the LHV efficiency is 44%.…”

This paper presents the results of technical and economic studies in order to evaluate, in the French context, the future production cost of electricity from IGCC coal power plants with CO 2 capture and the resulting cost per tonne of CO 2 avoided. The economic evaluation shows that the total cost of base load electricity produced in France by coal IGCC power plants with CO 2 capture could be increased by 39% for 'classical' IGCC and 28% for 'advanced' IGCC. The cost per tonne of avoided CO 2 is lower by 18% in 'advanced' IGCC relatively to 'classical' IGCC. The approach aimed to be as realistic as possible for the evaluation of the energy penalty due to the integration of CO 2 capture in IGCC power plants. Concerning the CO 2 capture, six physical and chemical absorption processes were modeled with the Aspen Plus TM software. After a selection based on energy performance three processes were selected and studied in detail: two physical processes based on methanol and Selexol TM solvents, and a chemical process using activated MDEA. For 'advanced' IGCC operating at high-pressure, only one physical process is assessed: methanol.

Partitioning of Lead and Lead Compounds under Gasification-Like Conditions

An investigation of the chemical form, the concentration, and distribution of lead species between the gas and condensed phase was carried out under gasification-like conditions. The influence of hydrogen sulfide, hydrogen chloride, and steam on the speciation of lead was studied. The gaseous species were determined online by molecular-beam-mass-spectrometry. The condensates were analyzed by standard methods. The dominant chemical forms were metallic Pb, PbCl2, and PbS. The experimental data were compared with the results of thermodynamic Scheil–Gulliver cooling calculations. Further, the experimental data was used as an input for a pseudoequilibrium model aiming at the determination of kinetic information on the underlying transformations.

“…In this plant, a 50:50 local coal/pet-coke blend is gasified with 2%-4% w/w of limestone (fluxing agent), in a pressurized entrained flow gasifier, at 1600 °C and 25 bars. The Puertollano coal is a high volatile bituminous coal, rich in a number of metals [6], while pet-coke, supplied by an oil refinery is generally a C-rich material with high concentrations of S, V and Ni [7]. The high slag/FA ratio (90:10 or 85:15) produced in the Puertollano IGCC plant is the opposite with respect to that of conventional pulverized coal combustion plants (20:80).…”

Demonstration Plant Equipment Design and Scale-Up from Pilot Plant of a Leaching and Solvent Extraction Process

Germanium recovery from coal fly ash by hydrometallurgical procedures was studied at the pilot scale (5 kg of fly ash/h). Results were used to design the equipment of a demonstration-sized plant (200 kg of fly ash/h). The process is based on hydrometallurgical operations: firstly a germanium extraction from fly ash by leaching and a consequent Ge separation from the other elements present in the solution by solvent extraction procedures. Based on the experimental results, mass balances and McCabe-Thiele diagrams were applied to determine the number of steps of the solvent extraction stage. Different arrangements have been studied and a countercurrent process with three steps in extraction and six steps in elution was defined. A residence time of 5 min was fixed in both the extraction and elution stages. Volumetric ratios in extraction and stripping were: aqueous phase/organic phase = 5 and organic phase/stripping phase = 5, so a concentration factor of 25 is achieved. Mixers and decanters were completely defined. The maximum extracted and eluted germanium was estimated and a global efficiency of 94% was achieved. The cost-effectiveness of the equipment was estimated using the Lang factors.
