The control of the particle size distribution of metal nanoparticles produced via aerosol condensation is a technologically relevant open problem, constrained by the limits of the construction materials and by the desire to minimise carrier gas consumption. As reactive impurities can be present in the carrier gas, we have reviewed the physical...

A systematic sensitivity analysis requires computing the model on all points of a multi-dimensional grid covering the domain of interest, defined by the ranges of variability of the inputs. The issues to efficiently perform such analyses on algebraic models are handling solution failures within and close to the feasible region and minimizing...

IGCC (Integrated Gasification Combined Cycle) power plants look promising for the environmentally- friendly, large-scale production of electrical energy from low-cost fossil feedstocks such as coal or refinery residues. In IGCC plants hydrogen is an intermediate product, as a syngas component, between the thermochemical section and the power...

The steady-state model of a molten carbonate fuel cell (MCFC) energy plant can be formulated with differing degrees of detail and implemented within any of the frameworks available today, but it is difficult to obtain an efficient, lean, robust simulation tool also capable of providing sensitivities. If such a tool were available, there would...

Molten Carbonate Fuel Cells (MCFCs) can be used for concentration of carbon dioxide in Natural Gas Combined Cycles (NGCCs) exhaust gas, at the same time increasing electrical energy: when used in combination with Gas Separation Membranes (GSMs) for final segregation of CO2, they constitute an interesting carbon capture solution. This paper...
