Mineral carbonation process for CO2 sequestration
(2009)Energy Procedia ~ Greenhouse Gas Control Technologies 9The most promising route for mineral carbonation is the aqueous process using naturally occurring silicate minerals. The overall carbonation reaction consists of the dissolution of MgO- or CaO-bearing silicates such as olivine, serpentine, and wollastonite, followed by the precipitation of carbonates such as magnesite and calcite. In this paper, we report the experiments to investigate both the dissolution and the precipitation processes, ...Conference Paper -
Pre-combustion CO2 capture for IGCC plants by an adsorption process
(2009)Energy Procedia ~ Greenhouse Gas Control Technologies 9A promising approach to provide in the near future electricity from fossil fuels, for the worldwide increasing energy requirements with near-zero CO2 emissions is the IGCC (Integrated Gasification Combined Cycle) technology with pre-combustion CO2 capture. One important aspect within this technology is the development of advanced processes for the capture of CO2, i.e. its separation from hydrogen, with improved efficiency to decrease the ...Conference Paper -
CO2 storage through ECBM recovery: An experimental and modeling study
(2009)Energy Procedia ~ Greenhouse Gas Control Technologies 9The permeability of the coal seam is the main petrophysical property controlling the performance of the ECBM operation, since it affects both the CO2 injection and CH4 recovery. In the present paper, coal swelling of intact coal samples is studied both under unconstrained and constrained conditions. Unconstrained swelling experiments are performed in a view cell under a static high pressure gas atmosphere, whereas gas injection experiments ...Conference Paper -
An improved classification procedure for the Hump Yard Lausanne Triage
(2009)OpenAccess Series in Informatics (OASIcs) ~ 9th Workshop on Algorithmic Approaches for Transportation Modeling, Optimization, and Systems (ATMOS'09)In this paper we combine an integer programming approach and a computer simulation tool to successfully develop and verify an improved classification schedule for a real-world train classification instance. First, we derive an integer program for computing train classification schedules based on an earlier developed bitstring representation of such schedules. We show how to incorporate various practical restrictions in this model. Secondly, ...Conference Paper -
