Resilient decision making in steam network investments

François Maréchal, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener

Steam is a key energy vector for industrial sites, used for process heating, direct injection and stripping, tracing and cogeneration of mechanical power. Steam networks transport steam from producers to consumers and across different pressure levels. The ...

Optimisation of unit investment and load shedding in a steam network facing undercapacity

François Maréchal, Greta Martha Van Eetvelde, Laurent Gabriel Félix Alexandre Stéphane Bungener

Steam networks and their utilities should be dimensioned to satisfy day-to-day demand as well peaks. Peaks can be caused by unit start-ups, extreme weather conditions or combinations of high demand from process units. During maintenance operations or unexp ...

MINLP Model and two-level Algorithm for the Simultaneous Synthesis of Heat Exchanger Networks and Utility Systems

François Maréchal, Alberto Mian, Emanuele Martelli

This work proposes a novel approach for the simultaneous synthesis of Heat Exchanger Networks (HEN) and Utility Systems. Given a set of hot and cold process streams and a set of available utility systems (e.g., gas turbine, steam cycle, boiler, etc), the m ...

Unsteady Aerodynamics of Low-Pressure Steam Turbines Operating Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

Nonsynchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in low-pressure (LP) steam turbines. These vibrations are often induced by a rotating aerodynamic instability similar to ro ...

Modelling of a steam network using data reconciliation as a management tool

Laurent Gabriel Félix Alexandre Stéphane Bungener

The first step towards managing and optimising the steam network of an industrial cluster or plant is to accurately measure the production and consumption of the different levels of steam. Measurement errors as well as unmeasured contributors lead to inacc ...

Effect of Steam-to-Carbon Ratio on Degradation of Ni-YSZ Anode Supported Cells

Jan Van Herle, Stefan Diethelm, Hossein Madi

Internal steam reforming (IR) of methane was investigated on Ni- YSZ anode supported cells, looking in particular at the effect of the steam to carbon (S/C) ratio on the degradation rate. The cells were fed with different H2O/CH4 mixtures during 100 hours ...

Thermo-economic optimization of a Solid Oxide Fuel Cell - Gas Turbine system fuelled with gasified lignocellulosic biomass

François Maréchal, Adriano Viana Ensinas, Laurence Tock, Priscilla Caliandro

Within the context of sustainable energy supply and CO2 emissions reduction a Solid Oxide Fuel Cell (SOFC) - Gas Turbine hybrid system, fuelled with gasified woody biomass for medium scale applications (8MWth,BM of dry biomass) is studied in detail. The sy ...

Accounting for expectations about the future: a dynamic discrete-continuous choice model (DDCCM) of car ownership, usage and fuel type

Michel Bierlaire, Aurélie Glerum, Emma Frejinger

Car ownership and usage can vary importantly across years due to various factors, such as the introduction of new governmental policies, changes in the available technologies or variations of the market features. In order to explain and predict these chang ...
